Stop damp before it ruins your walls
Rising damp, penetrating damp, and condensation each damage your property in different ways, but they all get worse when ignored. We diagnose the exact cause, fix it at the source, and make sure it stays fixed.
We don’t just cover up damp. We find the root cause and eliminate it permanently.
Rising damp, penetrating damp, and condensation each require completely different treatments. We use moisture meters and thermal imaging to identify the exact source before any work begins, so you only pay for what’s actually needed.
Every damp proof course we install comes with a written 20-year guarantee. We use proven chemical DPCs, specialist renders, and tanking systems that stop moisture returning, not temporary fixes that fail within a year.
Damp treatment often means removing plaster back to the masonry. We don’t leave you with bare walls. We replaster with renovation plaster, skim to a smooth finish, and leave the room ready for decorating.
We quote a fixed price after surveying the problem. No hourly rates, no surprise extras, no hidden charges for materials. The price we quote is the price you pay. Guaranteed.
A proven four-step process that fixes damp at the source.
We visit your property, take moisture readings, and identify the exact type of damp affecting your walls.
Contaminated plaster is removed back to bare masonry. Salts and moisture are cleared to give treatments a clean surface.
Chemical DPC injection, tanking slurry, or waterproof membrane is applied depending on the diagnosis.
Renovation plaster is applied, skimmed smooth, and left ready for painting. The room looks better than before.
Damp is three different problems that look alike from the sofa. Rising damp climbs from the ground through brick and mortar and leaves a tide mark, salts and blown plaster along the bottom metre of a wall. Penetrating damp comes through the wall from outside, follows the weather, and sits wherever the render, pointing, cill or gutter has failed. Condensation forms on cold surfaces in rooms that are not ventilated or heated enough, and shows as black mould in corners, behind furniture and around windows. Each needs a different fix, and the most expensive mistake we see is a wall replastered, or a damp course injected, over a problem nobody diagnosed.
So the survey comes first, every time. We take moisture readings up the wall and across the room, look at the outside of the house, check ground levels, render and gutters, and look at how the room is heated and ventilated. Then we tell you which kind of damp you have and quote the right job. Where it is rising damp, that means a new chemical damp proof course, the salty plaster removed and a renovation plaster system that resists the salts left in the wall. Where it is penetrating, the fix is outside and the replastering waits until the wall has dried. Where it is condensation, we treat the mould, repair the finish and tell you straight what ventilation and heating will stop it, because a damp course does nothing for condensation.
The North East's housing makes damp common: solid-walled Victorian terraces and Tyneside flats with bridged or missing damp courses, Sunderland cottages that are all ground floor, coastal homes from Whitley Bay to Seaham taking salt-laden rain, and new-town estates in Washington and Cramlington where condensation rules. We have worked on all of them since 2009, with our own team and no subcontractors, and we hand the room back replastered and ready to decorate.
Where we install a damp proof course, you get a written 20-year guarantee against rising damp coming back through it, and it transfers to a new owner if you sell. For penetrating damp, condensation and the replastering that goes with them, our workmanship promise applies: if something we did is not right, we come back and sort it.
The problem, what we did and the result, each from a real review.
Rising damp leaves a tide mark up to about a metre high with salts and blown plaster along the bottom of the wall. Condensation is black mould in corners, behind furniture and around windows, often upstairs. Penetrating damp comes and goes with the weather and sits where water gets in. We take moisture readings and tell you which it is before we quote.
Stripping, treating and replastering one room is usually two to three days on site. The new plaster then needs a few weeks to dry before painting, and we tell you when it is ready.
Yes. We come out, take readings, find the cause and give you a fixed written quote with no obligation and no travel charge. If the right answer is ventilation rather than a damp course, we say so.
No. Damp-proof paint hides the stain for a season and traps moisture in the wall, which makes the plaster fail faster. The wall needs the cause fixed and the salty plaster replaced.

“On pricing this job, the customer used an 'experienced tradesman' who used a steamer to remove wallpaper from plasterboard walls and they were removing the jointing tape and the skin from the plasterboard, thus leaving an unlevel surface. I suggested reboarding but they said they didn't have a lot of money to play with. While the 'tradesman' was removing the wallpaper the customer demanded via text that I go that very minute to see what a mess this tradesman was making. While we were working, her husband commented on how we were the best tradesmen they'd had, as we just got on with the job. I'd mistakingly missed out a price for a ceiling, so I skimmed that for no extra charge as the price had already been agreed. (No mention of this was in her review however). We always ask customers to check the work before we leave and both said they were 'over the moon' with the work and they paid via bank transfer a few hours after I'd left. It's clear the 'tradesman' hasn't prepped the newly plastered walls properly, as the paint has now blebbed. That's not a fault with the plastering, but with the lack of preparation on the decorator's behalf. It took 7 days for the customer to let me know she wasn't happy (and that was after the walls had been painted!).”
Checked & Vetted“I contacted Dean about the job and he was on hand to review damage, give a reasonable estimate within my budget and was on stand by once property dried out. Work started promptly and done with the estimated 3 days to a very high standard as always by Dean and his soon. Clean and tidy work too. .”

Very professional, workmanship to very high standards was told the ins and outs of process of work to be carried out and very clean. Amazing job for the price. Always on time, would highly recommend. Will definitely be using dean in the near future. .”
Checked & Vetted“Dean came out to give me a quote, he knew what needed doing and I was happy with what he quoted. He took down 2 ceilings, replaced them, skimmed and then put up some coving. I can’t fault his work at all, the ceilings look amazing, he left my home clean and tidy. I’d highly recommend. .”
Checked & Vetted“Dean at Absolutely Plastered is the only tradesmen I know that I can rely on! He always responds to requests! In this instance, we wanted some pretty poor brickwork covered at back of house & Dean advised other options that I was not aware...”
Google“I had Absolutely Plastered out to inspect a damp problem in my home, he was knowledgeable and we agreed a price. Dean was prompt, came out when he said he would, installed a new damp course and plastered. Very reasonable and I’d highly recommend.”
