“Great company — built my extension years ago and recently a garage conversion into an office, plus other building work. Respectful and quality finish, I highly recommend.”
“Scott… has completed the groundworks and drainage for my wrap-around side/rear extension. Scott was professional from start to finish, he has great communication, and exceeded my expectations. He turned up everyday, rain or…”
“Great guys to work with, highly skilled and people you can trust to do work properly and leave to it. I would highly recommend to anyone wanting quality service.”
Damp gets blamed for a lot in older Leeds housing that isn't actually rising damp — condensation from poor ventilation, penetrating damp from failed pointing or a blocked gutter, and a bridged damp-proof course from an outside level built up too high all get lumped together and treated the same way, which is why so many damp 'fixes' don't actually work. CLM Projects assesses damp honestly first, then treats the actual cause: repointing, guttering and drainage repairs for penetrating damp, ventilation improvements and extraction for condensation, and re-plastering with the right breathable materials once the source is dealt with. Where a job genuinely needs an insurance-backed guarantee from a certified damp specialist, or turns out to be rising damp needing a new damp-proof course, we bring the right specialist in and manage their work as part of the project — we won't claim a certification we don't hold, but we will make sure it gets done properly and you're not left finding that specialist yourself. Fully insured, Leeds-based, built on trust and built to last. Send us photos of the damp and we'll give you an honest read on what's likely going on — free, no-obligation.

FAQs
Damp Proofing — Your Questions
Is all damp the same problem?
No, and that's usually where damp treatment goes wrong. Rising damp, penetrating damp and condensation have completely different causes and completely different fixes — treating condensation like rising damp, for example, achieves nothing. We diagnose which one you actually have before recommending anything.
Do you do damp-proof course work yourselves?
We assess it honestly first — a lot of what looks like rising damp is actually penetrating damp or a bridged damp course from ground levels built up too high, both of which we fix directly. Where it's genuine rising damp needing a new chemical damp-proof course with an insurance-backed guarantee, we bring in a certified specialist and manage their work as part of the project.
Why would I need a certified specialist rather than just you?
Mainly for the guarantee. An insurance-backed guarantee on a damp-proof course has to come from a certified surveyor — we're honest about that rather than claiming a certification we don't hold. What we do is bring the right person in and stay in charge of the project, so you're not left finding and managing a specialist yourself.
What's the most common cause of damp in Leeds homes?
On older terraces it's often penetrating damp — failed pointing, a blocked or overflowing gutter, or a ground level outside that's been built up above the damp-proof course over the years. Condensation from poor ventilation is also very common in well-sealed, well-insulated modern homes. True rising damp is less common than people assume.
Will you just re-plaster over it?
Not without dealing with the cause first. Re-plastering over an unresolved damp problem just means it reappears, usually within a year or two. We fix or arrange the fix for what's causing it, then re-plaster with the right breathable materials.
