I was at a house doing some minor plumbing when the damp proofing company came in with their meter and very quickly told the householder there was a lot of damp so needed tanking, replastering etc. I was there on my own when it rained and I saw a cascade of water coming off the roof because of a damaged gutter so water was going down the wall. The dampproof man never looked at the outside of the house.

[@alanyoung7532]

This sort of useless guesswork is not untypical, particularly by sales based damp-proofers. Ironically moisture meters are only reliable for use with untreated timber. Here is a quote from the manufacturer (Protimeter) “Contrary to popular belief, a moisture meter is not a diagnosis tool. Rather, it helps an inspector make an informed call about moisture’s presence within a space or material. If your meter is giving you a high reading, that merits further investigation -- dampness may not be the reason for the measurement; metals and salts cause false-positive readings.” What is needed is a thorough investigation of the whole house to track down the actual sources/s of excess moisture, rather than concentrate on its symptoms (damp patch).

[@crazykittenvideos855]

Great video Roger. We got a survey on our house that cost us hundreds and was rubbish. They didn’t look in the loft or lift drain covers and said we might need a new roof. In the end I got a local builder round and for £50 he did the lot. He said it was a great house, roof was completely sound. We have been happily living here for 15 years. Would never get a home buyers report again!

[@spanishpeaches2930]

On the three properties we have bought I , as a builder, did my own surveys. Have seen too many surveyors talk bollox about house problems and half arsed checking. I was a builder btw.

A good builder knows more than 95 percent of these surveyors. Real experience and expertise comes from hands on experience. I have two degrees one in construction management and one in building surveying, but I have worked most of my life as a builder. Most of my knowledge was gained from being a builder and getting my hands dirty

[@rumtumbugger]

Before I even watched this video I could diagnose all the problems. Solid stone walls - check. Vinyl paint - check. Cement render - check. Gypsum plaster - check, bad drainage - check. Basically the full set there all the ingredients needed to make your house damp. Roger pretty much nails them here so kudos to him - most builders are completely ignorant of old techniques and requirements, understandably - and he's absolutely right about damp proofing salesmen - selling crap with a meaningless guarantee. Old property needs to to be breathable - if that sounds nuts it did to me too, but its beyond doubt - anyone with similar issues should grab a copy of a book 'The Warm Dry Home' > it absolutely explains all the causes of damp and solutions and might be the best £30 you ever spend if your older house is given you angst!

[@mikeg7746]

Spot on Roger. Always look outside at gutters, down pipes, drains and surface water. We had an issue where a surface drain and down pipe where running down the outside of the drain i.e. into the ground. £250 in materials and a weekends work, problem solved.

[@markthomasson5077]

As an retired architect, I 100% agree. Most problems are leaking drains and blocked gutters.

[@justmeEnglandUK]

I always find most damp is caused by broken gully pots or bad cracked connection to drains . Pot gully pots are heavy and settle over time and often cause collars connection to break . I did a front gully a few week ago again it had been chopped badly to fit onto the drainage pipe originally in the 1800s . It was replaced with plastic gully and rubber adaptor connector No more damp. . it's always a good idea to look in the pouring rain to see if the downpipe are filling up and the gully's are taking all the water off the roof . Make sure the water actually going into the gully not backing up or spilling over . Look in the manhole to see if it's flowing correctly . Another one I did was a house build around 1800 again the drain went off at 45° from the pot gully which had a 90° outlet to make it fit the smashed off the bottom of the gully outlet pipe and the bottom of the drain collar and butted them together . All the rain for 124 years had been seeping out the bottom of the drain and back under the suspend floor . A drain CCTV inspection only shows the inside of the pipe and the connect looked good but the external pot chipped off the connection caused the issue . The front door stone surround had dropped slightly near the drain and the damp around the subfloor increase during rain which pointed to the pot gully . The customer and the drainage company were skeptical about my diagnosis so it was exposed all the soil removed and first rain it became obvious it was the cause of the damp . The house also had a damp kitchen in the rear extension floor outside wall had a cast iron soil stack to the bathroom above to a pot slow radius bend below the concrete flags again just remove the flags exposed the pot bend and left it open it was obvious what the cause was the cast iron pipe had been cemented into to pot bend collar sewer pipe , the cast pipe had rusted causing the iron pipe to expand in the pot collar which cracked the pipe out of sight in the back side of the bend in the soil . So every time the toilet was flush the water would trickel out and under the kitchen concrete floor . A plastic slow bend radius pipe was fitted and rubber straight adaptor collar was chopped off and new plastic soil pipe to the toilet with a access point on the bottom of the stack . No more leaking soil stack and the floor dried out within a month and all the damp went away. Roger spot on with all he said often damp is a combination of lots of little things a few additional air bricks under the floor marking sure it cleans unobstructed airflow is possible also Louvred vents deflect water from getting in rather thank the open square type . New concrete damp courses in old houses don't work that well and it often takes months to dry out especially over winter . Damp is caused by excessive water in the area remove the majority of water and the damp goes away . It's cause by leaking drain leaking gutters .blocked drains and gully pots clean them out by hand with a thick rubber Gloves ever six months Make sure they are flowing freely sometime damp is causing by leaking water mains in the area if water is ponding utilities can sample test water and tell the difference between tap water sewer water or rain water . If it leaking water main utilities companies have listening devices which can pin point the leak often this service is free under leak lines the repair my not be unless it a shared communal Water main . Often the majority of this water leaks into the drainage system so if drainage is flowing permanently during in a manhole it's leaking water mains this is very common . If you can dig and exposure gullies and clean out gullies lift manhole covers and crawl under floor do the detective work it . Often damp proofing not required it simple masks the problem it doesn't cure it . And sometimes damp is caused by ground water which can't be stopped it can only be managed and diverted .

Nice to hear that damp can be solved with these little tricks! What an honest, helpful guy!

[@glennpowell3444]

The very reason so many old 16th and 17th timber framed buildings still exist is because they were drafty and no fancy moisture treatments applied to either the infill brickwork or wattle and daubing.They breathed very well.Ok they were buggars to heat but no condensation issues.Also they sat their timbers typically on hard stone peg points and "bund" masonary which was impervious to water.Much like we use class A engineered bricks today as the footings spring.

As a builder of 8 years i can really appreciate these videos - Problem solving is a real skill that requires a ton of experience and common sense, thanks roge!

[@justinstephenson9360]

Great video. Reminds me of the "damp issue" in the living room when I bought my current house 30 years ago. As required by the mortgage provider we paid for one entire wall to be subject to damp proofing. About 18 months later we discovered what the real problem was - there was a leak in the bath drain which was directly above the living room. Simple to correct and should have been spotted by the mortgage provider surveyor. Times move on but damp proofing scams remain constant.

[@rumtumbugger]

Scam is the most appropriate word, that's exactly what they are.

[@Cotterdale]

Coincidentally, we had a similar story - our bath emptied straight into a 'coal house' that was adjacent to our kitchen wall. The surveyor missed it - but reported signs of damp in the kitchen. Of course, the damp-proof expert recommended a full treatment of the kitchen wall - neither spotted the real problem. I fixed the 'real' problem with the usual plastic fittings for a few pounds.

Once you have dealt with gutters, drains, external levels, underfloor vents, The cement based external render is a big part of the issue as it doesn’t breath very well. Ideally a soft lime based render. Internally, the best product is one of the studded vertical DPC.

It's comfortable, economic, cheap and healthy

[@malachy1847]

Great Upload, and great Advice, i remember someone talking about ," Air Changes" in an old Edwardian Property, after Double Glazing was installed the people thought of a simple centralised unit pushing fresh air down from the loft , to flush out and dilute the warm damp air, but achieving that throughout a property would be a bigger job without duct work, a lad said just make sure as you said that the all Vent bricks are doing their Job and even put in a few more at a higher level then do go a head and install that unit , BUT Scalp a Half Inch off all the internal Doors to the rooms thus allowing the property to get air flows going and to breath ...

Great video. Hope Rosalind’s house is sorted.

[@peterwoodhead2569]

Had a similar problem in my house when I bought it 35 years ago. I was told a damp course had been installed but there was clear evidence of rising damp. 4 damp eradication companies all suggested the same expensive remedial work. I discovered that there was a damp proof course one brick up from floor level and the house had then been rendered and plastered to the floor. The damp was being drawn up in the render and plaster. Removed skirting boards and tanked up to damp course inside and out, cut the render off to just above damp course and added a bell mouth and the problem which had been there for 25 years before we bought disappeared over night.

[@LivingALife4Me]

Brings back memories of work on previous homes. I am pleased I learnt a lot from good tradesmen ready for the next time. Sure helps when looking around houses before buying as my son found to his benefit!

[@stevesvids]

To test for Rising Damp do a salts test. This tells you the degree of hygroscopic salts in the evaporation line which indicates that ground salts have travelled with the ground water up to the point where pure water evaporated away, leaving salts behind. If there are high salt readings this is indicative of rising damp problem due to lack of or broken down damp proof course. All salt contaminated plaster should be removed as hygroscopic salts will even attract atmospheric moisture causing condensation issues. Signed An expert. P.s. also that front render issue was due to that downpipe discharging into the ground .

I had to double check this was Roger and not Pete! What has happened to you? Some good sensible advice.

[@SkillBuilder]

It is all about balance and that is something sadly lacking in Peter Ward's advice. The idea that there is no such thing as rising damp and all damp treatment companies are crooks is just plain cranky and you can see it has become an unhealthy obsession. His latest book is full of contradictions and repetitive ranting against individuals who have dared to disagree with him. What we are looking for is truth not dogma and you get to the truth through calm analysis not by starting out with a mindset. If this house had a straight mortar bed I would have recommended DryRods because they would do some good and no harm but it is not suitable for a chemical damp proof course so we have to look elsewhere. The damp proof company recommended tanking but I think that has been done. The excess moisture in the ground around the property is very easy to reduce and, hopefully, it will help any issues.

[@GK-qc5ry]

Would be nice to do a follow up Roger on the house when it's done 👍

[@grahamblake7198]

I am amazed that qualified surveyors still recommend these specialist damp companies. So many obvious causes of dampness in that property. Did I see bamboo growing around the possible cracked drain?

[@tomf4087]

It is indeed common for it to be condensation. I think a lot of people do their cooking with boiling water steam that hits the walls and turns to water again. Then people do a ton of washing and constant drying of clothes. But dont open windows. Not easy in winter i know, but they will dry faster with less condensation.

[@Henry.Riccato-Smith]

Great video to get in the mindset of a builder inspecting a property. Useful stuff for the house I'm off to view with a big damp wall.

[@MrJFoster1984]

Helifix Patch Pins for the render. Pin the drummy render back with stainless steel pins which are then bonded to the render with resin. Only a drill hole to patch after installation. Save you knocking off the the old render and reapplying new render. 👍

[@stephenribchester2185]

The kitchen only looked bad because of the wallpaper. If it gets hacked off and re rendered wont be a problem. The "knock it off to 1.2m" would ring alarm bells to me as there seems to be an idea now to coat the wall then stick 8x4 plasterboard on with special grip fill. Damp Sam swears by it but it is a load of bollocks as far as I am concerned. You could say her surveyor is at fault but then again he might not of been able to see it. When I sold a terrace house few years ago, surveyor came and was chatting and said he wouldn't move any furniture. He then put his damp meter down on the table and went outside to look at the roof, so I used his meter to pinpoint were I thought the damp in the living room was, then shoved the settee up against it. Problem solved no damp in my house. House looks ok just wants tidying up.

[@SkillBuilder]

Sticking plasterboard on a wall with a damp history is nonsense. Elements board is waterproof and insulating and you can plaster straight onto it. It also keeps the salts out.

[@wilkes27]

Would love to see you go back, or get some footage of some of the work discussed having been completed and an idea of how much better the place is. I installed Aco drainage myself, had the old lime mortar reinstated and used wet room plasterboard on the internal wall. Its worked wonders!

[@geoffpeirce406]

Period buildings require period materials and techniques. Replastering only seals damp in the wall and prevents testing finding dampness after the works have been completed, suggesting that the damp is cured but you have just trapped it in the wall. Use Lime, it breathes and evaporates moisture. Chemical damp proof course. Has it ever been proved to form a new damp proof barrier? Chartered Surveyor

[@SkillBuilder]

It is somewhat depressing to find a chartered surveyor who doesn't do his research. The use of siloxane as a chemical damp proof course is highly effective and has been tested independently all over the world. Nothing beats a physical damp proof course but a reduction of 90% in rising damp is not to be dismissed. Your observations about lime are also a little wide of the mark. Buildings do not breathe. The process of evaporation will dry a wall out but some of the moisture ends up in the house and that has to be removed through ventilation. Basically you are using your home heating to dry out the walls and you are then throwing the heat out through extraction to get rid of the excess moisture. That is why we have damp proof courses. I don't know why some people find that hard to grasp.

Is a humidistat an expensive dehumidifier ? It sounds to me like a drainage issue coupled with a lack of ventilation solved very easily with a large dehumidifier inside. That solved my problem. My issue is I don't open windows and have little permanent ventilation. Since the fireplaces were closed down of course morning condensation caused mould etc. the dehumidifier stopped that and reversed it nearly overnight. Dig the garden over, resettle the ground making sure it finds a drain and bobs your uncle...
