Damp, mould & leak services in Addlestone

Addlestone's housing spans Victorian and Edwardian terraces near the town centre, interwar semis in Woodham and Row Town, postwar estates around New Haw, and new-build flats from the Addlestone One regeneration. Proximity to the River Bourne and Wey Navigation adds groundwater and flood risk, while older solid-wall properties and poorly ventilated modern flats each bring their own damp and condensation problems.

Common damp problems in Addlestone homes

Riverside damp near the Bourne and Wey Navigation

Properties in Ongar Hill, Coppermill and parts of Addlestone Moor sit close to the River Bourne and Wey Navigation, where high water tables and periodic flooding drive rising damp and saturated solid floors. We regularly find tide-marked plaster, failed damp-proof courses and slow-drying subfloors in these homes, often worsened by garden levels built up against original brickwork over decades.

Interwar semis with solid walls and pebbledash

The 1930s semis common through Woodham and Row Town were built with solid or early cavity walls and pebbledash render that traps moisture when cracked or poorly maintained. Combined with single-glazed bay windows and shallow lofts, these homes show classic penetrating damp at wall junctions and condensation-driven mould in bedrooms and stairwells during colder months.

New-build flats and regeneration developments

Flats in the Addlestone One town-centre regeneration and other recent developments near St Paul's often suffer from tight airtight construction without adequate mechanical ventilation, leading to interstitial and surface condensation in bathrooms and kitchens. Snagging issues such as poorly sealed balcony doors and plumbing penetrations have also caused early leaks behind plasterboard in several new blocks we've surveyed.

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

Tip: If a damp patch keeps coming back after redecorating, it is almost always a symptom, not the problem. A survey that finds the source first saves paying for the same repair twice.
