Say Goodbye to Rising Damp - A Simple Solution!

[@Nettsinthewoods]

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

[@HorusOne-p9o]

well done

[@daves4026]

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

Same here got the rods, and about to do it over the weekend. Did you chase off ALL the plaster upto say a metre? Or just tidy it up and repaint?

[@huntergatherer8972]

How have you found having the rods in? Has it worked?

[@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

[@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. 🤔😎🇦🇺👌

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.

[@JackSmith-kp2vs]

@davidvestey6014 Why not just lime render and plaster the wall and use a breathable paint. What is the obsession with trapping damp in. Walls have to breath

[@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

[@houseinavan194]

My thought's....many cavity walled houses I have worked on had the BPC bridged by decades of debris, the solution is take out a few bricks at intervals scuff your arms to pieces getting in there to clear the Debis to below BPC, one I did has 400mm built up!!!, then put in several air brick's along the wall, no return of internal damp after severe years, keep the solution simple in keeping with the construction of the building.

[@bp4682]

i had severe rising damp on an internal fire breast wall i used the Dryzone rods , 7 months on the wall is Bone dry....thanks to watching one of your videos Roger

[@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.

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.

"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]

Completely agree. Good intentions, lack of research.

[@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.

[@jhutfre4855]

@lksf9820 True, they also didn't say anything about the temperature in the room. If it "feels cold." Already an indication if a cement render was used along with obvious question if the issues were there before.

[@completepreservation]

WOW….Must be the only house of cavity construction without a physical damp proof course. At least eliminate bridging of the damp proof course by plaster, solid floor, or debris within the cavity…. What about drains, or even a mains leak.

[@hunchanchoc8418]

My 130 year old house surprisingly has cavity walls. But no dampproof course. Or foundations. They just laid big flagstones on the earth and started building the walls on top. The soil is only about 14 inches below the floor. It's very very damp.

[@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.

[@stevenmarquiss9213]

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.

[@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.

[@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]

[@lg_believe333]

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.

The walls of the house are brick cavity which go all the way to basement, DPC level was 600mm basement level, I have used tanking slurry to waterproof the internal walls then foam grabbed 37mm insulation plasterboards on. I drilled a hole through cavity wall this morning which was the original external wall now part of interior as extended out 2.4m.

[@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!

we have rising damp. Had it for 15 years and now really want it sorted. The floor is concrete and that is damp and we can see mould forming on the carpet tiles. Is there anything which can be done (a treatment) for the floor? Then paint the brick work outside to stop penetrating damp...? Any suggestions would be greatly appreciated. Thank you

Sam said he did a 200 year old house - Mine is 230 with rubble walls yet the insurance Co OK'd the damp Co to inject. Some of the stones are solid granite and I pointed this out i.e. there's no way that would work as the liquid would just squirt out.. Now I have the same damp problems.. and the cowboy firm doesn't want to know. (full & final settlement paid so ins Co don't want to know either)

[@chrisp3330]

See my comment above, mate - my house is 320 years old of similar construction and is now breathing, dry as a bone, and holds more heat that any modern house ever will.

Can you do a video on the digging of a French drain mentioned in thus ?

[@awilderireland]

Loads of vids on French drains on KZbin. Although some say you shouldn't put one right against the house. Fecked if I know. Like so many things building related there's lots of conflicting info. Sorry if I've made matters worse! But the KZbin vids would at least give you an idea.

I’ve had good results with these on a 200 year old property recommended!

[@alanyoung7532]

I could be wrong but it appears that the cavity has now been bridged with these rods, which is inconsistent with the manufacturers recommendation viz : With cavity walls "If dryzone rods are being used, each leaf should be treated separately" They also say "It is essential when investigating the potential for rising damp to eliminate other sources of water ingress. Care must be taken to eliminate other potential sources of moisture, especially in the colder months, and it is therefore essential to ensure that a full investigation is always undertaken. If any other sources are identified then these must be first eliminated before a proper assessment of any rising dampness can be made as it can be very difficult to distinguish between two or more interfering sources of water ingress".

[@SkillBuilder]

Nothing wrong with that. It would seem to me to be honest.

[@alanyoung7532]

@@SkillBuilder Roger as you will know wall ties contain a drip (or similar) in the middle for good reason as water always gets through the outer skin of a cavity wall and is likely to cross the cavity unless prevented from doing so by design. Reducing the integrity of a cavity wall could conceivable also be a Building Regs issue. This is why the manufacturers of the rods state and illustrate (in their guide) each leaf should be dealt with separately to retain a clear cavity rather than provide it with bridges every 115mm or so. It is not good practice and will probably negate any assurance offered by the manufacturer. As a general rule the manufacturers guidance must be followed unless there is a justified reason for not doing so. Sorry to disagree on this one.

[@spencerphillips983]

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

[@kevinp4771]

Your channel is amazing! Thanks for everything you are doing! Hoping to move into an old Victorian place soon and damp is an issue in the rear section which is basically half the house underground. Do you think these could be installed internally as well and plastered back over?

[@Dave-in-France]

Excellent, clearly explained video, as always. These dry rods seem to be a pretty good product, I'll have to get some.😃😃

[@francisrobbins1499]

Had outside of house done In that coloured silicon render, don’t want to go hacking it off so can you drill from the inside by taking off the skirting and drilling nearly all the way to the outside?

[@billrook829]

Will this technique work if you have damp coming in from above.I have s flat under s house snd damp comes in from soil surrounding and from associated contact with steps and structures above?

[@andriuxandriux4818]

What if the inside wall was block and the mirror line did not match ...will the rods still create barrier on inside wall? What if block was used for both walls ...can I drill I to old dpc..insert rods and create new barrier or next mortor line above old dpc...which would seem pointless to stop damp

[@michaeljones2478]

Can I do this from the inside to out, as outside is under ground and inaccessible ? TIA

[@collinsoseibonsu4544]

[@mrai9199]

What's the update, did it do the job?

[@eugenemcgowan2575]

Would dry rods work in a stone built house. Our house. has 1m thick walls and we have a damp problem.

[@knowitall3503]

Clear cavities to ground level are key. Especially in the corners. The drive to "save the planet" by turning your house into a fluff filled hamster house will have a negative impact on your house. Like the pipe over the drill bit tip. I'd leave the drill holes to vent.

[@tonyefc8423]

It's why God invented 'depth stops" on hammer drills.

[@pjmoseley243]

My house was built in a slight dip where rain pooled looking back I remember the carpet underlay would always smell damp. many years later far past the 10 year NHBC Its still damp. and smells damp. I missed the chance to get it properly surveyed by a soil specialist I imagine its lost alot of value due to this. Is all Lost for me?

[@willdrake6646]

I have used the dry rods, and I'm still having issues. I even put a second layer under the floor on my Victorian terrace in Brixton. What would be your other suggestion? Re-render with Slka 1 on the interior or add a membrane-like your other video?

[@SkillBuilder]

I am sorry to hear that DryRods haven't solved your problem. Can you send me photographs? I will come and look if you like because I am not far away but I would need to film if for Skill Builder

[@willdrake6646]

​@@SkillBuilderno problem at all. How would you like me to send the photos?

[@stevesvids]

Internal plaster line just nipping down below the original damp proof course will cause these very symptoms. Always check this first. Simple remedy. Chop away plaster that breaches the DPC line. Done.

[@vimtohasatoe1]

Hi we've had vinyl floor in the passage there was damp in the floor so we had a damp proof membrane and finding slight damp coming up surrounding walls. Will the rods be enough to sort the issue? Thanks

[@TrevorMcGrathPhotography]

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

[@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.

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

Hi I’ve got rising damp from a block internall wall , but it’s bin layed on a concrete pad, , how do i get around this please ??

[@pip1723]

We have a 1830s cottage sandstone construction a new roof and gutters and we had a problem with rising damp on the back wall, so I used stormseal on the said wall the damp has now moved from the back wall to the upstairs partition wall it's baffling the house has been refinished top to bottom can't work out were it comes from .Perhaps a dehumidifier up stairs will solve it ?

[@SkillBuilder]

I think you need to consider that it is condensation.

[@djpaulsid]

Do these work on concrete walls?
