Damp in Hitchin Homes
Old Town with timber-framed houses on Tilehouse Street and Bucklesbury hidden behind brick or render, and the Georgian town houses along Bancroft, are among the most difficult buildings to work on. The solid walls, old DPC, and the render that is not supposed to be watertight in the first place allow for moisture ingress, before considering the River Hiz flowing through the middle of the town, which causes a high degree of ground moisture in the surrounding old streets.
Head out into Walsworth, Hermitage Road, and Victorian terraces around, and rising damp starts to become the more common cause, where the original DPC has deteriorated or is bridged by the raised paths and flowerbeds. On the newer estates towards Letchworth Road and the edges of town, it's more often penetrating damp from tired guttering and render, or condensation building up in homes with limited ventilation. Either way, the smart move is always to do a proper waterproofing survey first, and where rising groundwater is a factor, we'll include rising damp treatment in the plan too.
Damp Proofing Services in in Hitchin
No two properties fail in quite the same way, so here's how we customise damp proofing in Hitchin to what's actually going on.
Rising Damp Treatment
Where rising damp is confirmed in Hitchin’s older solid-walled properties, we install a replacement damp-proof course but only after a thorough survey confirms it’s the genuine cause.
Penetrating damp
Worn render, ageing pointing and deteriorating window reveals can allow water into Hitchin’s timber-framed and Victorian properties. We identify the exact entry point and tailor the treatment to address the underlying cause.
Condensation & Mould
Homes and flats with poor airflow around Hitchin town centre and the Old Town often need improved ventilation rather than an unnecessary damp-proof course. We focus on the actual cause to provide the right solution.
Timber & Rot Treatment
Woodworm and timber decay can affect floor and roof timbers in Hitchin’s older medieval and Victorian properties. We treat the damage and address the underlying moisture issues to support a lasting damp wall treatment solution.
Basement & Subterranean Waterproofing
Properties near the River Hiz may experience increased water pressure affecting basements and lower-ground spaces. We install high-performance tanking and waterproofing systems designed to withstand hydrostatic pressure and provide long-term protection.
Damp Surveys
Our damp surveys provide a clear written report, helping buyers understand the condition of period properties in Hitchin’s Old Town or Victorian terraces around Walsworth before committing to a purchase.
How to Tell Which Type of Damp You Have
Rising damp: Usually affects the lower sections of ground-floor walls and may cause tide marks, flaking plaster or salt deposits near skirting level.
Penetrating damp: Typically occurs when rainwater enters through defects such as damaged render, pointing, gutters, roofs or window surrounds, often creating localised damp patches.
Condensation: It is caused by moisture in the indoor air and commonly appears as misted windows, surface moisture and mould around windows, bathrooms or poorly ventilated areas.
These signs can overlap, so a professional damp survey is the best way to confirm the actual cause before treatment is recommended.

From Damp-Affected to Dry and Healthy
Restoring a Damp-Affected Home
Persistent moisture had already caused visible damage to the internal walls of this North West London property. Following a thorough survey, we developed a tailored damp proofing solution, replaced the affected finishes, and addressed the underlying issues. The result was a genuinely dry, healthier home with noticeably improved indoor air quality.
