How working with us usually goes
Call us and tell us what's happening
You tell us what you've noticed, from mould spots to crumbling plaster. We listen, ask the right questions, and arrange a suitable time to inspect the property.
We survey the problem properly
We visit, assess the signs, and work out what is causing the moisture issue. You get honest feedback and a free quotation based on what your property actually needs.
We carry out the right solution
Once you're happy to go ahead, we complete the work with care and clear communication. You get a property that feels drier, sounder, and far less stressful to live or work in.
What we offer

A straightforward way to deal with damp
Damp has a habit of starting small and turning into a proper headache before you know it. At Northeast Damp and Ventilation, we've spent more than 30 years helping people get to the root of the problem, and we still believe clear advice matters just as much as the treatment itself.
As a family-run business, we know you want someone who turns up, tells you the truth, and does the job properly. We carry out free damp surveys and quotations across Durham, Newcastle and Sunderland so you can understand what your property needs without feeling pushed into anything.
Practical help for homes and commercial properties
You might be looking at flaking plaster, black mould, or that musty smell that never quite goes away. We tackle rising damp, condensation, dry lining, ventilation and exterior moisture problems with a practical approach that starts with proper diagnosis. Northeast Damp and Ventilation works with homeowners and commercial customers who want the cause found before money is spent on the fix. We serve Durham and surrounding parts of the North East with workmanship that aims to sort the issue properly, not just cover it up.

Damp-proof course injection
Long-Term Damp Control: Designed to provide effective rising damp control for at least 20 years.
We install chemical damp-proof courses to stop rising damp in walls. This involves injecting a damp-proof cream into the mortar course to create a barrier that prevents moisture from rising through the walls. Suitable for homes, extensions, garages, and older properties.
