Damp Proofing Stevenage

Stevenage is a town of two halves: the medieval Old Town with its coaching inns and cottages, and the post-war New Town estates built as one of Britain's first designated New Towns. Each brings different damp problems, and we diagnose the real cause, rising, penetrating, condensation, or construction-related moisture, then fix it with a survey-led approach backed by a written 10-year guarantee.

Damp in Stevenage Homes

Stevenage Old Town's High Street cottages and coaching inns are centuries old, often solid-walled with no original damp proof course, making genuine rising damp a common finding once other causes are ruled out.

The New Town estates, built from the late 1940s onwards around Bedwell, Broadwater, Shephall and Chells, use a mix of construction methods including some concrete and system-built homes, where penetrating damp, cold bridging and condensation tend to be the bigger issues rather than rising damp.

Pin Green, Symonds Green, and the newer developments towards Great Ashby often show condensation problems linked to modern insulation and sealed windows trapping moisture indoors. Whatever the era of your property, the right starting point is always a damp survey, and where structural moisture is suspected, we also offer a waterproofing survey.

Damp proofing solutions

Damp Proofing Services in Stevenage

Whatever the property and whatever the cause, we cover it, with each job linked to the right specialist treatment.

Rising Damp

Confirmed rising damp in Old Town's solid-walled cottages and older buildings, treated with a new damp proof course only where the survey shows it's genuinely needed.

Penetrating damp

Penetrating damp through render, flat roofs, and poor pointing is common across Stevenage's New Town estates in Bedwell, Broadwater, and Chells.

Condensation & Mould

Condensation and black mould in New Town homes with sealed windows and modern insulation were resolved with proper ventilation rather than an unnecessary damp course.

Timber & Rot Treatment

Woodworm and timber decay treatment for roof and floor timbers in Old Town's older cottages and converted buildings.

Basement & Below-Ground Waterproofing

Waterproofing and tanking for cellars and lower-ground rooms in Stevenage's older housing stock.

Damp Proofing Stevenage FAQs

Which parts of Stevenage do you cover?
All of Stevenage, including Old Town, Bedwell, Broadwater, Chells and the surrounding New Town estates.
I have damp in an Old Town cottage. Is it rising damp?
Often, yes, but we confirm the cause with a survey rather than assume, since penetrating damp and condensation are just as possible.
Does Stevenage's New Town construction affect damp treatment?
Yes, many New Town homes use system-built or concrete construction, so condensation and cold bridging are more common than rising damp, and treatment differs accordingly.
Can you treat damp in a New Town flat or maisonette?
Yes. It's usually condensation from poor ventilation or penetrating damp through flat roofs, and we identify which before recommending work.
How much does damp proofing cost in Stevenage?
It depends on the cause and extent of the problem, so we give a clear, itemised quote after the survey rather than a generic figure.
Is the work guaranteed?
Yes, with a written 10-year guarantee that's transferable if you sell.
