Say Goodbye to Rising Damp - A Simple Solution!

I’ve just been installing the rods. I’ve not done anything like this before. It’s amazingly easy, but hard work for a small female like me. I’ve got the Stormdry express waterproof mortar to tidy up the holes. It’s always so helpful to have tutorials like these and see what the professionals do. Thank you

Used it on a terrace chimney breast which was salting on the plaster surface. So far so good. Viewers should note the rods have a best before date as the chemical has an active ingredient so there is a shelf life to unopened rods

[@mikeraphone6745]

The old pub in East Hagbourne called the travelers welcome had a unpainted brick exterior. When the property was sold and converted into a house the owners complained about the damp . It was there painting of the old clay bricks stopped the wall from breathing and it was down hill all the way. The solution I told them is to strip off the outside paintwork as that was causing the problem.

[@rodmills4071]

I see people here in australia paint old houses and decks with acrylic paint. If it's no maintained, that's the end of the timber... dryrot. The moisture gets in and can't get out. Like wrapping it in plastic. 🤔😎🇦🇺👌

[@waynewinky2754]

As an architect following investigation if the root cause of the damp cannot be identified and remedied on site, then we sometimes specify an injected DPC resin system into the masonry applied at around 150mm above floor level. Internally we then specify 2 coats of a painted waterproof coating system, whether it be bitumen based or liquid tanking applied to the exposed brick/block from the floor level up to and 50mm above the injected DPM line so that their is a continuous barrier at the base of a wall if water is trying to move upward. However, we would then specify a lime plaster scratch coat and finishing coat as it allows the plaster to breath compared to standard gypsum plasters. Lime plaster is used in damp and cold environments like churches as it doesnt show any inherent damp or tide marks visually caused by a damp masonry substrate.

[@halbraun123]

Could you make a video on this

[@Uk-Writer]

Well you need to find a new career as rising damp is usual,y caused by bridging the damp proof course by platiscide in the awful render on this building basically sealing the damp inside the building , ask the Dutch they don’t use any form of a damp proof membrane and laugh at us doing so and look how wet their country is

[@m4inline]

I used these on my garage wall but miscalculated the wall thickness and drilled straight into my winter tyres.

[@baldutt3223]

So helpful

[@philprice12]

I believe the small amount of damp would be dispersed if you had sandblasted the useless bitumen coating off to let the wall breath. Also cleaning out the debris from the cavity would solve this. Pointing the holes with cement rather than lime mortar will also not help the wall breath. Last job we did was an old Manse that was dripping wet. We dug out the floors and fitted underfloor heating . After cutting 3 foot sections through the 9 inch solid walls with a concrete chain saw . Fitted 9 inch dpc through the wall repointed and came back 2 weeks later to cut out the 3 foot in between and over lapted the pieces of dpc THen did the 4 inch internal walls the same way . So the whole house was sliced through and a perfect damp barrier installed. 3 chains used at £290 each. Saw cost 2 grand. Was water fed so a messy job. You could sell the saw on after doing the job. Doubt you can hire these. Brilliant tool slices concrete/ mortar like butter. The only way to do a perfect damp cure on an old house. Phil

[@SkillBuilder]

Hi Phil I have one of those saws but you can cut out lime mortar with a block saw of recip saw with tile cutting blade. I don't like the bitumen but the damp is on the inner skin so your theory is not applicable to that. The damp was there before the bitumen. breathe not breath.

[@kevinhancock4064]

@Skill Builder hi mate love your channel so informative and how you meet woth other skilled people . I'm a qualified brickie I do mostly jobs I fit in around main job 4 now (family and security wins here ) I can run my hand over bottom of front room above skirts and paint will be kn my hand it's clearly not dry snd tbh fed up of trying to make good that wall . I've in the past (past house with an ex) had damp done . And a good job was done. That time the walls were hacked off a metre up and tanked and replastered. . I think those pods be an easier place to start 4 now I'm not to bad at plastering but if I can get it done easier I'd like to . And maybe a water proofer on outer skin. But bearing in mind I have a pebble dashed house with 100mm gap at bottom where red tile has been fixed(easily removed)

Hi! do you such works? How can I contact you to carry out such works? Do you cover W2 area in London or know anyone who does?

[@SimonHunter1959]

Key moment at 1:49 "we decorated the outside to stop any penetrating damp". Presumably with the bitumen? The salts on the inside wall look fairly recent so it is plausible that they only appeared AFTER the bitumen was applied. Bitumen won't let the bricks breathe naturally so the salts (carried via moisture) have to go somewhere. Was the bitumen applied as a response to damp issues elsewhere? But yes, would agree with other comments that the source needs to be established first eg remove the skirting, check for bridging of plaster to floor, floor coverings, floor, water/drain pipes etc.

[@twmd]

but its a cavity wall. so the main issue in these houses is rubble and cavity wall insulation - it's an absolute must to inspect the cavity - should always take out a few bricks

[@davidhunt1760]

I agree, the second I heard him say they had painted the outside I was thinking a different way to Roger. Sounds like the mositure is pushing out around the sides of the slab. I would ease off the skirting boards and check the plasterboard wasn't touching the slab also. First time I've disagreed with Roger however

[@jannenreuben7398]

By "decorating" the outside wall with what looks like modern plastic paint all you've done is seal in any moisture in the wall. It's like putting on a plastic mac immediately after a shower. The bitumen on the brick plinth will have the same effect. The concrete floor will likely just push more moisture into the walls which now can't escape because of the coatings and those damp sticks you've just fitted (if they work at all). This house looks like it has had everything done that you should never do to an old house. I bet someone has done the pointing in OPC as well.

[@gilespanton9354]

Great vid showing your techniques but Cement is one of the main reasons those old buildings suffer from damp, using lime based mortor is so essential to maintain breathability throughout an old house

[@benedictearlson9044]

You can avoid that by only painting the walls when they are fully dry, after months of hot dry weather, difficult that in the UK. Masonry waterproofing liquid rather than bitumen paint is the thing to use, it's breathable and rain washes off the wall meaning the walls above the DPC will be much drier and the house warmer. Or try breathable masonry paint.

[@jannenreuben7398]

@@benedictearlson9044 Waterproofing liquid is the worst thing to use on old porous bricks because, like plastic paint, it only seals moisture IN. Remember that water exists as a vapour as well as a liquid and if that vapour condenses in a cold wall (i.e one below the dew point) then those coatings will only stop it evaporating. That's when you start getting damp pushed through internally. If the water freezes it'll spall the outer brick face. The only paint you should ever use on old brick is limewash. The trick to treating damp in an old property is to accept that the fabric probably will get damp and doing your best to help that moisture evaporate with ventilation and appropriate materials.

"We decorated the outsides" There is the issue right there, they've locked the moisture into the walls and it can't get out. So they've charged the customer for causing a damp issue, then charged them again to try and cure it. If you took the paint off you'll find the brickwork is sopping wet. Looking in the background in the first few seconds shows similar houses with no paint on them, i'd be asking them if they have any issues first.

[@Scott-cm8sv]

[@patrickhouston2610]

And you know what happens to brick when you lock in the moisture, the brick will eventually fall apart, collapse and some moisture through evaporation may still escape into the cavity air space, especially if there is no decent ventilation.

[@willbee6785]

Be brutal. Check rainwater down pipes under the ground at the point of dampness. Take out some plinth bricks to see the cavity detail and to check for a d.p.c. Dig a trench at same location for clues. Lift that room flooring and do the same; dig down below expected d.p.c. height to investigate build details. Use your technical X-ray specs (knowledge) and using process of elimination to eventually come up with a permanent solution. Specifically in the video, that plinth paint is definitely not helping, plus the wall paint; what type is it? There’s a lot more things you can do, but each building has it’s problems and solutions. It’s having the knowledge and experience to solve them.

[@AQIB32]

[@RLFWE1]

The external cement render is probably a big contributor, not vapour permeable. Well done on putting the "french drains" in that's definitely going to help.

[@davidvestey6014]

As a Chartered Building Surveyor I make my living diagnosing damp problems. The house wasn’t damp when it was built so often it is a question of just reversing all the “improvements” that people have made. Now you have tried to insert a DPC just above the internal floor level so if it works (which I doubt) you have trapped all the rising damp in the skirtings, exactly where you don’t want it. Ask a Chartered Building Surveyor… we don’t sell products.

[@jimh4072]

I had dampness on an upstairs bedroom wall caused by cracks in the render. I was told the wall had to have breathable paint to let the moisture out. After two years of problems I bought some wet rot hardener that is basically a very liquid plastic. I sprayed it on the outside of the wall with a cheap hand sprayer (thrown away afterwards) two months later and the inside wall is almost dry. I am painting over it with some stain block paint then normal masonry paint. Saved me a fortune in re rendering costs.

The outside skin of brickwork with a cavity was designed with a view to take the rain and then dry out. The air gap between the inner and outer skin may have been bridged with mortar etc on the wall ties. Thus encouraging damp to traverse these "bridges" making the inner wall damp. Insulated cavities use other technology together rid of moisture build-up, ie drip vents in the perpendicular motar lines.

I have the same problem with my wall in the cupboard under the staircase where the smart meter and gas boiler is. It’s an end terrace house with render covering a solid brick wall that was built in 1935. I had a damp surveyor look at it and he said the moisture on your wall is caused by condensation and recommended shaving off an inch from the bottom of my wooden door using a hand plane. And then cutting out a hole in the door and screwing a metal vent to increase ventilation. The damp surveyor also recommended using a chisel and a mallet to take off an inch of plaster from the bottom of the wall, just above the wooden laminate flooring thats glued to a subfloor with air bricks outside. Chiseling off the plaster all the way along the bottom of the wall and leaving it for a while to dry the wall out before placing some skirting board over it and painting over it and re-plastering the wall above. I’ve done the door but I haven’t chiseled off the plaster at the bottom of my wall yet. I ventilate my home everyday now as well. And sometime ago Rentokil put dryrods in my outside wall but because the brick is hidden under my render I was concerned the dryrods wasn’t drilled into the mortar, in between the bricks but was drilled into my bricks. Also as well I recently noticed my block paving outside is just above my air bricks outside. I was considering installing an eco drain outside but I feel my block paving needs to be lowered 75-150mm below my airbricks and then re-plaster the black plinth either side of my airbricks which is below my render before sorting out my wall inside my house. My neighbor also suggested never use waterproof sealants on walls but lime mortar cement instead. So, for the moment I still have salts on my inside wall in the cupboard under my staircase that comes back when I use the hoover to remove the salts from my wall.

[@joncarolepaish2899]

Tanking a damp/wet wall is only hiding the problem! The answer is to let the moisture naturally out by using a properly breathable lime plaster and mineral based paints which also breathe properly. By tanking the walls you'll trap the moisture in and the salts from the ground will eventually cause the bricks to crumble. The se dry rods might stop further moisture ingress, but you've got to let the existing moisture out!

Ok, I misunderstood. Roger's explanation @5:45 to 6:10, is worth listening to a second time. Thanks lads!

[@jackkruese4258]

Hi I noticed that you drilled holes in the cement between the bricks, how essential is that ? What would you have done if the wall had been covered in pebble dash and you didn’t know where the gaps between the bricks where ?

[@SkillBuilder]

You need to find the mortar line for best results and cut the render so it doesn't bridge the dpc.

[@jackkruese4258]

@@SkillBuilder Ok thanks for letting me know.

[@chasnbons]

Brilliant video. I've just bought the kit and it arrived today. I wondered if you or any of your subscribers could tell me what the opposite end of the rod cutter is used for? Thanks

Can I get this in Ghana?

[@johna7075]

Not convinced this time Roger. A lot of your stuff on here is solid gold but I'd be looking at a lot other things before sticking these things in. Most damp issues like I see here are penetrating issues from dodgy gutters, render, cavity trays/bridging (if you have cavities). Years ago, before I knew better I tried something similar and the results were generally disappointing.

[@SkillBuilder]

Nobody said you should ignore other causes of damp. The rods are effective with rising damp and that is proven.

[@Scott-cm8sv]

@@SkillBuilderSorry, disagree completely there mate. Rising damp doesn’t exist, there’s always another source of moisture that’s usually fixed really easily. Complete waste of money 🤷‍♂️

[@chrissyjames7711]

@@Scott-cm8sv water penetration through brick does exists though scott ,

[@Scott-cm8sv]

@@chrissyjames7711 Hey Chrissy, yes it does, but rising damp it is not the 'cause' of dampness that is implied by the Damp Industry (and this video). Water will travel through brickwork for sure, but it is a process, not the cause. The fact of the matter is if you treat the cause of the dampness (penetrating, leakage, condensation etc.) then the problem will go away. Inserting rods into a wall and not addressing the real problem is not the way to go, you will likely just see the problem move elsewhere.

Absolutely true john a...this is the biggest con trick by builder's like the ones on this video..they make £5000 or more per house...😢and it does not work- I repeat it does Not work..don't be fooled guys- research peter ward English heritage on KZbin and you will see the truth of these rotten to the core con-men.....

What would you recommend for a house 200 years old stone 600mm thick walls

[@CambridgeCookie]

Don't seal them with anything, let the walls breathe as they are meant to. Remove any cement and repoint in lime. Lime plaster any internal walls rather than gypsum or plasterboard.

[@paulgallagher6225]

If the rising damp is more apparent in the inside wall than the outside, should you drill and insert rods in the interior wall?....or must it be done from the outside. Thanks for getting back to me.

[@SkillBuilder]

In or out is fine.

[@YorkshireD1]

Can i not use these rods if i have damp on internal walls?

[@michaelwilliams4086]

I was really pleased to find out that it wasn’t Sam who had the dampness problem, but the building he was working in. I wonder if the bitumen on the outside of the wall was slowing down evaporation of any moisture in the bricks. I don’t know how the damp proof cream works when you’re pumping into a wall with a cavity, there must be quite a bit of loss as it tickles into the wall void🤔

[@jonp6798]

I hadn’t heard of these rods until now. Handy solution if there’s a cavity, not used it myself though.

[@DMC888]

They’re meant to stop the holes just shy of breaking through the brick, because as you say it would just go straight through to the cavity.

[@SkillBuilder]

The cream is leached out by the moisture. It doesn't drip down

[@Retro-cabin]

Your supposed to damp a cavity from both sides which manages cream loss.

[@robertmawby3021]

Bitumen paint? There is your problem, get it off and let the damp evaporate out.

[@TrevorMcGrathPhotography]

Can these rods be used in a single 6" block wall?

[@megaz1963]

Hi I got the same problem on the walls but my floor is wood suspended on beams with a cavity under. My walls outside are pebble dashed rendered how would i drill the rods into that without knowing where the morter line is, is it possible Thanks.

[@CambridgeCookie]

Removing the cement render wall so the walls can breathe would be a good start in a addressing any trapped moisture, rather than masking inherent issues.

[@full-affect7580]

Do you place below dpc or above??

[@SkillBuilder]

If you have a dpc it is unlikely to have failed. Look for other causes first

[@andriuxandriux4818]

Can't find any info as to inserting these into block at dpc level

[@only1kingofsing]

Will these rods dampproof the last inch as if you think the damp could be seeping up from inside floor it could still make its way up through the inside inch the rods never covered....

[@impamiizgraa]

Are you vacuuming after drilling the holes, or blowing air?

[@SkillBuilder]

yes

[@jamespaterson9801]

if the original damp proof course fails on your 1970s bungalow. do you use the dry rods above or below the original damp proof course?

[@SkillBuilder]

I am not sure why the original damp proof course would fail but I would either go one above or one below. I don't see a lot of damp proof course failing unless there has been a lot of structural movement or bridging from debris in the cavity.

[@SkillBuilder]

On the landing. The boiler needs a carbon monoxide detector but that is different to the Nu Aire unit.

[@jamespaterson9801]

Ok thank you for the reply and information, ive go a damp surveyor coming out today i will see what he has to say. Then take the necessary action. As i can see a water mark rising from tge skirting board on the ground floor only in one room though. Seems it could be rising damp..

[@jamespaterson9801]

@@SkillBuilder hi the damp poof surveyor has said the walls through out the bungalow including the party wall and internal walls all have very high moisture readings and has concluded we have rising damp?

[@theK174]

I have a similar situation but on stone cavity walls. Can this be applied in the same way ? Regards

[@frankellymusic]

Can Dry Rods only be used on brick walls. My walls stone. Would they still work?

[@spencerphillips983]

Interesting, so for this job it's purely exterior? You don't have to do this on the inside?
