Damp in Northampton homes
Northampton grew on the boot and shoe trade, and whole districts of Victorian terraces were built for that workforce in Far Cotton, St James, Semilong, The Mounts and Kingsley. Built with solid walls and damp proof courses now well over a century old, this is exactly the stock where damp problems take hold.
In that older housing the common issues are rising damp from a failed or bridged DPC and penetrating damp through the solid walls. Many older town and village properties are also built from local Northamptonshire ironstone and limestone, which are porous and need to breathe, so the wrong cement based repair can trap moisture and make things worse. Low lying ground along the River Nene, in areas like Far Cotton and St James, adds flood history and ground moisture to the picture.
Northampton expanded hugely from the late 1960s, so the town also has large modern estates at Hunsbury, Wootton, Weston Favell and the Eastern District, where the main problem is condensation and black mould rather than structural damp. Because the cause varies so much, we establish it with a professional survey before recommending anything.

Signs of Damp in Northampton Homes
Whether you are in an older terrace, an ironstone property or a newer estate home, these are the signs worth a professional look:
Important: treating rising damp as condensation, or the other way around, is one of the most common and costly mistakes made by non specialists. A professional survey is essential before any treatment is recommended.
How We Work, Survey to Completion
Professional damp survey
A qualified specialist surveys your property with a calibrated moisture meter. Where rising damp is suspected we take plaster samples for salt analysis to confirm it, separating rising damp from condensation or penetrating damp.
Written report and diagnosis
You receive a written report with what was found, the diagnosis and the recommended treatment. If the problem is less serious than another company quoted, we will tell you that too.
Fixed price in your report
A fixed price is included in your report. No day rates and no hidden extras, so you know the full cost before deciding. The survey fee is deducted from the works if you proceed.
Treatment and installation
Our trained technicians carry out all treatment to current British Standards, BS 6576 for chemical DPC injection and BS 8102 for any below ground waterproofing.
Written guarantee
Every installation comes with a written 10 year guarantee, transferable on property sale and accepted by solicitors and mortgage lenders.
What Our Customers Say
Genuine reviews from Advanced Damp customers.
"I had two other damp surveys on my home and they were only interested in concluding that it was rising damp so that they could charge me a lot to inject into my walls. Matt on the other hand has proper experience and techniques with thermal imaging, and he understood what the issues really were. He gave holistic advice on how to really solve the problem, and at much less cost."
"Michael was an incredible support during a very stressful period. He provided a thorough, fair, and honest assessment, and his use of modern testing and technology ensured everything was measured accurately. Thanks to him, we now have a clear and reasonable remediation plan."
"Lionel was super helpful and efficient. He sent the detailed follow-up docs the same day. Very impressed by excellent service provided by Advanced Damp, thank you."
