Recommend someone for damp-proof treatment?

lukester

Wondering if anyone here can personally recommend a good outfit to damp-proof a few walls. I have damp on two party walls, and got it treated by a cowboy over a year ago- there was a slight improvement in some areas, but still damp there. He has since left the country, so I'm looking for someone reputable now

Thanks

Naming of companies and/or individuals is against the rules as it can lead to spamming or shilling. It's well covered in the charter.

I spent several years working at this craic in UK and Ireland.

I'll come back with justifications if needed but for a short comment the following are facts.

Chemical injected remedial DPC's do not work.

check out the small print you have to get the wall dry in order for the DPC to become effective, if you can get the wall dry why do you want a remedial DPC?

electomagnetic Remedial DPC's are a scam you will be told if you query this that no body has proved that they don't work, this is true but you would be poorly served if this was the logic you based your decision on.

99.9% of the time where either of the systems appears to work is through the use of remedial plasters with salt inhibitors and waterproof additives and/or fixing the leaking gutter/high ground level/poorly detailed solid floor etc.

If you are seeking professional advice, do not seek it off someone selling a product, seek it off someone selling independent advice.

Abso-bloody-lutely. And make sure the "consultant" confirms to you in writing that s/he has no product to sell and no connection to any company that does have a product to sell. Anyone can call themselves a consultant, even though some of them are no more than salemen.

Cheers for the advice.

I already had the DPC injected into the walls, 2 years ago, by my disappearing act builder, and the damp has not gone away. It's funny, I spoke to a friend yesterday who's an engineer, didn't realise he'd worked on stuff like this too, and he said pretty much what you did, that injected DPCs don't work, and the best solution is some kind of waterproof plaster, he mentioned something called Thoroseal (think that's it, had to Google it).

waterproof plasters can have their own problems, weak points, try fixing anything through them sockets etc, and watch what happens

if possible in the location of the problem consider the solution used for a few hundred years, wainscotting, effectively a ventilated dry lineing to dado level, can be done to ceiling or even a vented skirting detail depending on extent/severity of the problem, ensure you isolate any timber from the wet masonry with brickies DPC not polythene across the whole area

good ventilation of any sub floor void adjacent will allow evaporation of water from the base of the walls and take the pressure off higher up
