We refuse to have unhappy customers
At Damp Armour Cardiff, we know how unsettling it can be to discover damp in your home. That damp patch on the bedroom wall, the peeling wallpaper in the hallway, the smell you just can’t shift — it can feel overwhelming, and the last thing you need is a contractor who makes it worse with confusing reports and unexpected costs.
That’s why we do things differently. Every job starts with a thorough survey carried out by one of our PCA qualified specialists. We take the time to properly understand the source of the problem before recommending any treatment, because treating the symptom without understanding the cause is a waste of your money.
We’re proud to be approved contractors for Sovereign Chemicals and Wykamol — two of the most trusted names in the damp proofing industry. That means the products we use are backed by proper guarantees, and the work we carry out is done to the highest professional standards.
We cover Cardiff and the Vale of Glamorgan, and we’re particularly familiar with the challenges that come with the older housing stock you find across the city — from the Victorian terraces of Roath and Canton to the period properties of Pontcanna and Llandaff. If you’re in Cardiff, we know your type of property and we know how to treat it properly.

Damp problems come in all shapes and sizes. Whether it’s a freshly discovered patch of rising damp or a serious timber rot issue that’s been building for years, our team has the skills and qualifications to deal with it. Here’s what we do:.
Damp Proofing
Rising damp is one of the most common problems in older Cardiff properties — and one of the most misdiagnosed. Our surveyors carry out a full inspection before recommending any treatment, including damp proof course injection, re-plastering with salt-resistant renders, and waterproof tanking systems for basements and below-ground spaces. We don’t just mask the problem — we fix it at source.
Dry Rot & Wet Rot Treatment
Rot can spread quickly through the timber structure of your home, and if it’s left untreated it can cause serious structural damage. Dry rot in particular can travel through brickwork and masonry, meaning it’s rarely limited to where you first spot it. Our specialists will trace the full extent of the problem, remove the affected timber, treat the surrounding area, and reinstate with quality materials — all backed by a guarantee.
Woodworm Treatment
Woodworm can weaken floorboards, roof timbers, joists, and structural beams over time. The good news is that if it’s caught early, treatment is straightforward and effective. We’ll survey the affected timber, confirm whether the infestation is active, and apply the appropriate treatment to protect your property going forward.
Property Surveys
Buying a property in Cardiff and want peace of mind before you commit? Or perhaps your mortgage lender or solicitor has flagged a damp issue in a survey report? We offer independent damp and timber surveys carried out by PCA qualified specialists, giving you an accurate picture of the property’s condition and a clear report you can rely on.
There’s no shortage of Damp proofing and timber treatment contractors out there claiming to fix damp.
The difference with Damp Armour Cardiff is that we’re fully qualified, fully accredited, and fully focused on getting it right first time.

“Dry rot in the floor joists — not what you want to discover! But the team at Damp Armour were fantastic.
Explained everything clearly, did a thorough job, and the price matched the quote exactly. Really pleased.”
Mark & Helen P., Canton
“I called them after a damp survey flagged issues on a property I was buying in Pontcanna. They came out quickly, gave me a really clear report, and were completely honest about what needed doing. Didn’t try to oversell anything. Would recommend them to anyone.”
James T., Pontcanna
“We’d been living with a damp problem in our Victorian terrace in Roath for two years, and two previous contractors hadn’t sorted it. Damp Armour actually took the time to survey properly and found the real cause. The work was done quickly, the team were tidy and friendly, and we haven’t had a problem since. Brilliant service.”
Sarah M., Roath
