I’ve only just finished watching this and being a roofer myself I’m sorry to say you would be better off ripping it off and doing it properly.

​@@TelferroofingI am not, you're right. I had a reroof done which was awful. I couldn't afford a reroof, did some research, worked round the mess and patched it up. 16 years later, not a single leak. It's not ideal, but sometimes you have to work around bad things to save the costs. That's all.

[@Telferroofing]

@@PhilipAlexander-rz6hy in some cases yes you could repair the bad areas and save the rest but this is beyond saving as the tiles used just aren’t up for the job even if they were fitted correctly, yes you probably could patch it up in a way but for me if it was my house I’d want it done properly regardless of cost to rectify but I guess that’s why they are in that position

[@nickhaley4663]

After 40 odd years in the building trade i'm glad that in a few years i can walk away. The ever increasing technicalities and specifications of modern building has just made it so much harder. And yet , here we have a couple of rank amateurs who think it's simply a matter of doing "the easy bits" and getting "an expert" in to do the hard stuff. Maybe when my arthritic knee gets to painful i'll do the easy bit, cutting it open, and then get an "expert" in to do the rest. He's assured me he's an experienced surgeon. Seriously though, this just highlights how little most people understand about modern building. None of it's easy, you can f**k it up in so many ways. They might stop that roof leaking but it will never be right. Firstly it's to shallow, 17.5 min for those tiles. Something like a Sandtoft 20/20 will go down to 15 but then the devil is literally in the detail. Anywhere that you have a penetration , like a roof light or soil pipe then it's so difficult to flash, as soon as a tile kicks up slightly you pretty much lose the fall and the water will run out sideways, your flashing have to be much wider. You better make sure your underfelt is good. Velux flashings at these low pitches are pretty much useless , on site lead secret gutters are much better but expensive to do And on another point, soakers DO NOT work on those large interlocking tiles, again the water will simply run off the side before it reaches the next tile, you might possibly get away with a WIDE cover flashing but a secret gutter is the approved solution, especially for wall abutments. Sorry for being pedantic but we are having to deal with these low pitches so often because of big single storey extensions. The "architects" draw it and then somehow we have to build it. Don't even start on the insulation/ventilation/VCL saga.

[@Palo-jm7xc]

@@ItzD3fW1sH It's exactly this. They think project management is easy but as soon as there is a problem it all goes tits up because they lack the technical knowledge to not only solve the problems but foresee them before they arise.

Also I didn’t see any ventilation in the roof. Assuming they have adhered to current Uk Building Regulations, they will have used a Pir Insulation that will promote Interstitial condensation. Amateurs should not run their own jobs. From further listening to their response the emphasis was always on the cheapest not the best or even the correct process to accomplish a good build. It was always bound to fail. Building is easy though !!!! Innit. It’s terrible easy to get it wrong that’s a fact.

I don’t know where to start Roger, I’m a general builder not a roofer but do most of my own roofs, I’ve seen some terrible work but that is right up there. The gauge of the tiles is terrible, doesn’t even match the other side, I’m guessing they weren’t roofers or experienced guys, I can’t believe any half decent trade would leave it like that. I’ve lost count the amount of jobs I’ve seen like this where customers have tried to save money by project managing the job themselves and trying to save money, what you get is each trade coming in and frankly not giving a f**k. It’s why I prefer to be in charge, that way, the buck stops with me. It’s pretty shitty of the window glass supplier not to supply a flashing kit too in my opinion. Whole roof needs stripping off and redoing tbh, I wouldn’t trust any of it.

[@benmason9135]

Looks like they've built the kerb too wide for your rooflights, they're not overhanging enough. And that lead is atrocious. Then they've used insulated plasterboard inside, so the overall thickness is so wide that it exceeds the black margin of the glass. Those rooflights can be absolutely fine if installed correctly - mine is perfect, but my single ply membrane dresses up and over the kerb, they have a generous overhang, and the water all drains away on the flat roof. That particular manufacturer doesn't recommend them for pitched roofs, whereas some don't care... but they're not guaranteeing the roof are they Sadly for this family there are just so many defects with this extension that can clearly be seen, that we can safely say there will be countless things wrong that can't be seen, some that could take longer than 8 months to manifest - woes won't end with those rooflights

[@lanista78]

This video made me genuinely sad, but not for Ross&Vicky, rather for our trade. The reason why they are in this mess is not that they cannot afford a better builder or a high quality project. They drive a Tesla (to see at the begin of the video), they can afford such a two storey extension etc. etc. I suspect that the real reason is, and this is a huge problem nowadays, that they simply don't value the job of a (roof) builder. The fact that you have to pay for a good, high quality job hasn't dawned on them. People have stopped valuing blue collar jobs, they stopped appreciating the experience, skills developed over years, knowledge. They watch a couple of KZbin videos and think "oh that's so simple, I can do it too, if not, I won't pay much for this job". It is a mess - I am almost tempted to say they deserve this. As for the job itself, honestly, tear it down, do it again, properly. It would save you a lot more in the long run.

[@Gward28]

A proper lead worker could create the correct traditional flashing to code that would solve the problem without a doubt but unfortunately the glass needs to be removed to flash it correctly as detailed otherwise is is just a matter of time before it fails again, unlikely to be a DIY enthusiast job though, you need to employ someone with the right skills and knowledge, it will cost what it costs but you will only need to pay once to have the issue rectified.

[@benmason9135]

I'm willing to bet there isn't an effective vapour barrier in that roof (especially with the lack of attention applied outside), especially with those recessed downlights, and I doubt they made a service void - and with moisture from a kitchen it's likely that the roof develops issues from the inside over time

[@SBIGDTSM]

Don’t forget on a vaulted ceilings, there’s two layers of insulation, between rafters then another cross laid across the rafters, in all the ones I’ve done, a vapour barrier has never been specified by the architect or asked for by building control.

[@benmason9135]

The foil face can be good enough as a vapour barrier IF it is foil taped together AND you don't puncture it with downlights etc. If fitting services, lighting etc. then companies like Celotex will insist that a service void if formed beneath the vapour barrier. As an architectural designer I always spec a vapour barrier, and building control should pick up on it (doesn't mean they will, and they don't take responsibility anyway). I see this done wrong all the time, and the importance of the vapour barrier often isn't understood, particularly when people order the electrician to fit lighting etc.

[@Beerpopnana]

There the wrong tiles on the roof. Marley mods go to 17.5 degrees

[@glenr901]

Poor advice given in my opinion the roof needs to come off and correct tiles for the low pitch situation fitted. The coursing of the tiles differs on both pitches of the roof. The correct water proofing and flashing detail around the roof lights also needs to be introduced. Not good advice given in my opinion.

[@gtimoney1]

Agree, Rogers a plumber or general builder? He is knowledgeable but he’s talking crap on this one.

[@craiglowe44]

Those windows will always cause headache, take them out and replace them with a proper window kit, even if you put a valley in and do a nice job of the flashing, ultimately you would still want to lift the window to get the flashing undernesth, which I assume some sort of Tiger Seal has been used to glue it down, in which case the chances of lifting it are very slim without damage. I have removed it before with a heat gun and acetone but the problem would be actually getting the acetone onto the sealant to start to melt it. Get an endoscope camera and check the inside of the ceiling void, the stains where the joists are running across the ceiling could very well be condensation. I don't know if you've used a vapour barrier, however, I can see there's alot of downlighters & speakers, so even if there was a vapour barrier there would be alot of weak points. It's best to check sooner rather than later, if you have condensation occuring in that ceiling/roof void it won't take long to rot the timbers. I'd say you'll probably be okay as tiles will give you some ventilation above, but do check before any damage is done to the timbers.

[@RPT7]

I’m sorry but that is horrendous workmanship, Just a few things spring to mind: • Roof battens/tiles incorrectly gauged leading to a terrible short course. • Roof tile bonds not central. • Dry verge caps terrible installed. • Need to ensure lead soakers are installed where it meets the wall not just lead cover flashing. • The flashing needs redoing around the roof windows with soakers installed. • Ensure at least 100mm headlap on the tiles due to low pitch. • Ensure 150mm lap on the membrane due to low pitch. • Probably no eaves ventilation. If they planned to live in the house long term i would personally start fresh on the roof, Remove all the tiles, batten, membrane and roof lights. Install the new low pitch Velux roof windows which has their our flashing kit instead of that terrible lead around the windows, New low pitch klober membrane, New marley mendip 12.5 degree roof tiles that are designed for these lower pitches and new lead step flashing against the wall with soakers.

These tiles have a minimum pitch of 17.5 and require a 100mm head lap (which needs checking) meaning they are not suitable for this purpose. Some of the setting out looks awful and rain could drive back up. I’d not sleep at night during heavy rain with this roof. With cost in mind, I would have those tiles off set aside and install onduline prior to reinstating the tiles and re doing the roof light. Admire people tackling self build/project management but this is an example where it’s not a straightforward build and specialist details that require professional advice. If this was drawn by an architect/technician these issues wouldn’t have arisen they would have been spotted.

Hi Roger, it looks as if I am a bit late to the party on this one but having spent the best forty years of my life dealing with these issues . Watching his video which is very good and clear as you say, I am reminded of just how difficult it is to see the cause of the problem from the outside when it is all covered over. In the old reliable style of starting with careful, persistent inspection and observation after a while my brain starts to join some of the dots, raising other questions requiring further observations. What I can see from outside is that the side cover flashings over the soakers do no come down far enough!, there should be at least seventy millimetres of cover, or down to no more that twenty millimetres above the soakers. A bit later we see the ridiculous badly fitted flashing along the back gutters!, that lead has to be fitted over the up-stand and doubled back on itself to prevent capillary transmission. Then an appropriate sealant between that lead and the glass. The next point is that the back gutters should have a flat 'floor' constructed in timber and covered with a sarking to prevent abrasion and adhesion, it should not be on the top of any tiles!, terminating at a step down to the side gutter thus allowing for an up-stand at the overlap of the lead. The next part shows the inside where the damp patches indicate any number of issues!, the primary one that I would like to know much more about is the exact sequence and application of the appropriate membranes and insulation, it is absolutely imperative that the vapour barrier is complete unbroken and effective and always between the inside and the insulation. With all that in place and working to prevent any condensation the roofing membrane must be fitted very carefully so that any water coming through the tiling gets diverted away from any cuts or corners in the roof-lights, Listening to your conversation with them I hear you explain much of the same points and by the look on your face I think that you also think that the whole thing has to be taken apart and done properly!. At the same time you are clearly trying to help them to avoid spending too much money and the 'fixes' you offer might help them but if as I suspect that they have serious condensation issues that will never go away!.

Hi Roger. The main take away for me, which is obvious but so easy to neglect, is to understand how structures are put together, how they work, so you understand the vulnerabilities, and the best way for me to learn about structure, and how things fit together is by observing 'detailed drawings'. A 'plan' and a 'section' is largely all you need to get an understanding of the structure. Then you learn more about loads and spans by checking out 'span tables' and then you could listen to an engineer talk about loads. Then I learn most about the quality of materials, and how they are used and work in the real world by people who have experience, such as you Roger. So thanks so much for your knowledge.

[@allthegearuk]

Surely the lead should be lapped over the top of the timber up-stand? That would be my guess is the main culprit. Also you should get a window with a frame that sits over and down the up-stand. Even if you do flash the lead over up-stand you would still need to seal with silicone/mastic which will eventually fail. Doesn't seem a good detail/design. We have had a similar window installed recently where the lead was lapped over and the window frame sits down over the up-stand. A bad design made worse by bad installation.

Hello Roger, I have a leak I think from my my flashing at a secondary chimney on my house. It leaks down the wall underneath into the property (slowly). I have been onto the roof and had a good look and now I think I see the problem. The chimney acts as a pivot point to where a small extension and rood was made (before my time). where the water may flow down to this chimney and around and off to a gutter, there is a section around the chimney where the flashing become flat and even dips before rising ever so slightly which causes a pooling and around there is the leak. I was hoping to do a quick job but now it looks like a possible restructure just to give an extra inch. I don't know what to do. I could remove a load of tiles but I'm not sure I can raise it to create water flow. the chimney is adjoined to my neighbours house he does not want me to remove the chimney even though it not in use. we still have another chimney which I fixed another leak from. what can I do abut my problem

[@jamespratt6600]

It is possible to produce the bespoke style skylight that has been attempted here, if you use something like the Cappex system . The glass should have an overhang on the front etc. As others have said the pitch is wrong for the tiles. Also with any flat concrete cross bonded tile, you need to use a secret gutter system at all abutments and then a small lead saddle to bring the water back onto the tiles. I think this style of tile is a bit shit myself anyway for this reason and the fact that you rely on an unseen, brittle water-track with a 5mm upstand to keep the water out! Oh yeah and they battened it in wrong too lol

[@tracer1127]

Unfortunately, this stuff happens when people try and cut costs and skimp on stuff. I fit kitchens and bathrooms and see shocking workmanship all the time. I have a job in a few weeks time where the customer has had an electrician fit his twenty grand kitchen and it’s a right mess. The customer having to pay for new end panels at over a grand and have all of the units unscrewed and re levelled as they are not flush with one another. If you try and save money or get stuff done on the cheap it often comes back to bite. This is a typical example of what happens when a bunch of builders that are happy to try and do the job on the cheap rock up. Everything has a cost to it if you want it done right. The second I get the impression that the customer is after a cheap job I just say it’s not for me and I’m not interested. I want to walk away knowing that both the customer and myself are pleased with the job so that they are happy to recommend me to someone else as I don’t advertise for work. If you haven’t got any pride in your work you aren’t a builder your a cowboy.

[@joekool5005]

That's designed to fail and leak. Two things I noticed without even watching the whole video but I have watched it all now. That's a ridiculously low pitch for a tiled roof. It should be a metal roof. Second, what are those dodgy skylights? Why not use Velux or similar? I would redo the whole job.

You need to name and shame that roofing company as if he did this to you then he will do it to others as well.

[@ballisticsmeg]

Good job we haven't had any rain in months otherwise you would have a pond indoors, hope and no hope ! not sure which one you had fit the roof lights

[@knott4me561]

The whole extension looks like a DIY project gone wrong.the Blockwork alone would question if it's been done right ,tied in etc cavity trays where needed .I'd rip them out for velux as there always going to be an issue

[@Virtualmassslave]

do you have beams around doors, windows, large openings in this construction? in the uk?

[@Solidsnake0208]

Why oh why would you not have just bought a proper pitched roof window such as a Velux, Keylite or even Fakro? EDIT: I now know, all in the name of saving money! Personally if a customer had told me they wanted to fit these roof windows in a pitched roof I would insist they change to Velux/Keylite or I would refuse the job.

[@VictoriousGardenosaurus]

Journeyman glazier from across the pond, only commercial though. I would put some roll on tar like flashing underneath your roof tiles. Next, install an aluminium flashing that will dive underneath your roof tiles, and capture the top edge of the glass, with a 1/4" or like 6mm(?) gap, which can be sealed with silicone. I had to replace an entire commercial job I installed back in 2016, as every window leaked. Haven't suffered from leak issues since, and I've glazed a million square feet since then.

My heart goes out to them, I can see the pain of their faces. We desperately needed a new combi boiler but everyone was fully booked. We did find someone that wasn't. That should have rung some alarm bells but we were desperate. What an absolute lazy install. Gas pipe running from an old live pilot lit heater that we asked them to remove. They removed the heater but ran the gas supply from that to the boiler so just as ugly at the end. Thankfully some 6 months later our star of a heating engineer Rob was available. He came to us and discussed the options. He came back for a day and made it all good. I have photos and video of the firm that came originally and just left us with an eyesore of a working boiler. At least we had hot water and heating. Rob removed all their pipe work, put in new copper and not the plastic push fit they had used and he hid it all, plus he bricked up the gaping hole left in the interior and exterior wall where the original flu was. They didn't even do that. Rob was so upset for us he charged a "mates rate" bless him and what a wonderful job he did. Modern Heating in Portsmouth. I won't name the other company but will say "If you can't get anyone because they are fully booked, avoid the lads that are available. They are available for a reason and it won't be a good one". I hope this lovely couple get their dream.

You should have refused Robs mates rates and paid him what he’s worth. He may feel bad for you but he’s still got to run a business.

Can sympathise - As a retired carpenter with a dodgy knee I got a firm (specialists - sic) in to sort some roof problems, I was so appalled by the work when I got up to check I threw them off the job and now (painfully) doing the job myself to get it done before the weather breaks

Thanks Roger for helping out

I live in Stafford interested to know who did this

[@rush211251]

Great video , it doesn’t look a great job to be honest . They should have used velux windows . Ive had my velux windows in over twenty years now , and have never let me down . I also fitted them myself just following the instructions . They’re also not that expensive to be honest .

[@davidmiller7771]

The whole building wants knocked down and done again , absolute shambles

[@NicholasFarnell-te3el]

Roger - as a Roofer with almost forty years experience - the first thing that struck me was; I can't believe the Architect specified singe lap concrete tiles on this extra low pitch - it's just asking for trouble - If I was given this job I would have take one look at the pitch and said No - you need a double lap roof covering - Eternits or composite slates, whatever, but not concrete tiles! the underfelt should not be relied on to keep the roof dry under driving rain conditions as it is obviously going to be doing here, and that gutter down pipe from the upper valley - handsome!

[@ats-tj9rc]

Surely, Building control and the Architect are employed to prevent this. Roger, Please set up a list of contractors vetted by yourself, that can prove that they have a minimum standard of workmanship and proud of the work they do. Paying you 0.1% of the contract, for arguement sake. Recommendation is always best! Another great disaster film.

[@andyharpist2938]

Ummm Total responsibility of design and construction from start-to-finish for, say, £100,000 of building for 0.1% (= £100). Sounds too good to miss. Form a queue here.

[@marcovanbaston1]

The first sign that slaps you in the face that screams out cowboy is the gauging of the tiles. I think the main problem is the lack of headlap on the pitch of the roof. Shocking.

[@PNH63]

Any time you have to use flash band flashing other than a temporary repair , it’s a bodge job

[@thegrandmuftiofwakanda]

Hi I'm that Roger Busy Bee off that Skill Builder channel wot you all like and tonight I'm off out for a night on the tiles.

[@shaunhennessy603]

What makes someone think they can project manage something they have no experience in? As a main contractor/project manager you have to know (even if its not your trade) if somethings right or wrong and that comes with years of experience. Most builders would have spotted this at drawing stage. I would have suggested dropping the eaves level to achieve 17° and get some proper roof windows not that shite! The fact they don't come with a flashing kit says it all! All though the roof is a bit of a bodge it's the design that's at fault.... The pitch and those windows!

[@superlazy3355]

The headlaps on those tiles on one side of the roof is woeful

[@scottnever8732]

the timber frame at 2.23 should be sealed, usually with this type of window its a rubber membrane nowadays. I would suggest in your situation you remove the window and install a lead apron to the frame and reinstall the window.

[@Mole-Skin]

I am a retired Carpenter/joiner (and have a reasonable knowledge of most other trades) and one thing that has shocked me when trying to hire Tradespeople these days is that virtually none of the people who come to quote had basic Public Liability insurance. Last time I worked it was only about £80 a year so there is NO excuse for not having it.. If you ask to SEE proof of Insurance they can get quite bolshy as if you are questioning their skill.. but.. they could burn your house down or injure your child.. It's not just about getting dodgy work sorted out.. Insist..! Thats my Rant.. One tip for the Roof I would offer would be to try to see what is happening actually when it is torentially raining.. I am not saying clamber on the roof but perhaps set up a camera.. It can be surprising how intense the effects can be when wind and rain work together. Stuff you can't see when it's dry. I would say the very low pitch could prove to be long term problem with our Climate change issues.. Perhaps change to Interlocking tiles (Santoft 20/20) I assume these aren't..? Possibly even over-heating the Glazing bonding adhesive keeping the 3x Sealed unit together.. It depends if they used a hot bitumen type or the better 'Tiger' brand.. If over-heated.. the outer glass could just slide down. I don't think this was the correct Sealed Unit design for a pitched roof. Your one is a flat roof design where the overhang of the glass deflects water evenly around the edge.. BUT... If the outer sheet of glass was the same size as the other sheets.. apart from the bottom 50mm overhang, then a suitable flashing could bond over the top and side edges of the glass helping to keep it in place and also deflect excessive Sun heat. I hired a 'clown' to do some Roofing for me some years ago and he left a stack of Concrete roof tiles balanced on the back of a Dormer ridge where it joined the main roof and went home.. Could have killed someone if someone hadn't spotted them and told me..

[@michaelhughes1131]

Anything that is done to repair will be reliant on a sealant which isn’t good long term The glass is sitting flat on wood even if the lead was folded under the glass it would not make a great deal of difference there is no drip to stop the weather getting under the glass panel

[@leeaston7101]

Wonder if they sorted it out iam not far away from Stafford

[@ziggyedison2409]

Roger, you mentioned the flashing around the rooflights should be underneath the tiles... Should the flashing from the wall be underneath too?

[@pureblood1415]

Water is getting in behind the lead at the top of the window. The breathable felt should go up to top of timber upstand. Bigger headlap on tile or higher pitch

[@michaelhughes1131]

The roof pitch determines the flashing anything under 17.5degrees is in my view too shallow using a proper manufactured roof window is the way to go

[@raymondpiper8294]

(Kevin McCloud walks in the rain over the untidy deserted house-build). "...and has returned to London, to her work in the city as a legal manager, despite the builders wanting decisions on the cladding. And now the full floor-to-roof German eco-glazing system is arriving tonight by lorry, needing a crane to off-load.. And the costs are in the region of £350,000 over budget." ( cut to adverts for Walkers Crisps)

[@peterdallyn6440]

It's absolutely shocking; any architect, architectural technologist or surveyor would have designed an extension that worked from the outset. A holistic approach is required, not just package by package (silo thinking).This would have negated all of the massive mistakes. Low pitch uncomfortable abutments to other windows. Nobody would let a DiY mechanic do an in-depth service on a modern car like a BMW; but people seem to be quite happy to take this approach on construction, nuts !!!!

[@petermaidment1175]

You were correct, MArley moderns are 17.5 degrees. That flashing is horrendous, i would b interested to see the manufacturer's spec for preventing water running down undeneath the glass at the top edge. Great content as always.

[@pureblood1415]

That was the first thing I noticed too, they are all over the place but not in a straight line, there is a straight steel above these doors but the gaps between the doors and steel are very inconsistent.

[@MrAndysoul]

That's a huge span for the bi-fold doors i did a few large spans like that a few years ago & Cat-Nic had to make special order lintols for them where they increased the thickness of the steel by a few grades It looks like a Bricklayer built the sides up to lintol level & then after a cheap fix was found someone else filled in the pike

[@lapinchiloca]

Two of my neighbours have had extensions made ovef the last 6 months, both with cracked roof tiles, exposed insulation and wooden frames flying away with the first storm...what's going on with "trade experts"?

[@itscoconutsaregood]

"Lead soakers" on interlocking tiles (single lap)! No, wrong technology. True soakers are for double lap tiles like slates or Rosemarys etc. Continuous overlapping lengths of lead strips are required like shown BUT with at least a 100 upstand, preferable 150. Secret gutters not recommended on "flat" roofs like these, get clogged up too quickly. Extremely poor detailing on top abutment gutter.

[@acraftman2823]

Turned in a bid on a complete custom built kitchen redo with everything they asked for along with two days of hand drawings had to take today off while they drive three hours to IKEA to look at "less expensive"cabinets I think you can probably guess at least one thing these skylights, those cabinets and a turd all have in common.I have been a certified Pella/Velux installer for thirty years and have to say that is one crappy looking kit and install. Best advice for the homeowner would be to not request those fella's return back again.They should have at least asked the provider of the units for installer referral's.

[@nickjones9254]

Am pretty sure Marley Moderns need minimum of 17.5 degree. Also, am pretty sure the black visible part of the glass should cover the timber upstaged. It looks like they have used a standard say 4 x 2 timber to form the upstaged and not followed manufacturers guidance on that.

[@simonthompson2107]

The client is still trying to cut costs on.the solution. Take it out and put a Velux in or another one with a purpose kit. It looks like the client is the issue here cutting corners and costs. The client says "if we can do the same fir half the cost." Hindsight is a wonderful thing, never cut costs on the roof, everything else is affected as a result. I wonder if they used green plasterboard.

[@240soundwave]

Flashband the hall mark of a cowboy agreed, quick fix, requires no skill. However I have used it on my own house as a "temporary" fix, it had a corrugated tin roof over the kitchen (high spec!) and it did a brilliant job for 7 years, when I took it off to re- do the roof it was so ridiculously well stuck to both the render and tin after all that time.

Judging by that workmanship, unlikely they requested visits from Building Control

[@Daniells1982]

Not convinced building control know what they're looking at to find the issues. Their expectation is that the roofer knows what they're doing and will question anything that doesn't seem right, which we know isn't always the case.

[@pauldavies7251]

Building control don't look at overall quality of work They just do the basic is the build safe to sign off at various stages Not to sound too harsh but she's tried to save pennies from day one it was only ever going to end one way by scrimping & doing some of the jobs themselves 🙈 I blame home improvement shows on TV everyone thinks it's easy to complete a job to a high standard, until they try themselves 🙈
