Damp in Slough Property

Slough has one of the most varied housing stocks in the Thames Valley, and the damp work reflects it. The town grew quickly along the Great West Road and around the Trading Estate, and at its heart are densely packed Victorian and Edwardian terraces, in central Slough, Chalvey and Salt Hill, often solid-walled. In these the damp proof course can be bridged, failed or missing, letting genuine rising damp up the wall.

Around them are the big post-war estates, the Britwell and Langley council estates and the Manor Park and Cippenham estates built for Trading Estate workers, along with 1930s and 1950s semis. In these cavity and non-traditional homes the problem is more often penetrating damp or condensation. And in Slough's many flats, converted houses and shared homes, the most common complaint of all is black mould from condensation, where warm, moist air and too little ventilation leave mould growing in corners and around windows.

The ground plays its part too: Slough sits on Thames river-terrace gravels over London clay, with lower, wetter ground near the Thames and the Jubilee River. With that range of property and ground, from terraces and estates to flats and commercial units on the Trading Estate, the only reliable starting point is a proper survey.

I have damp in a Victorian terrace in Slough. Is it rising damp?

It can be. Slough has densely packed Victorian and Edwardian terraced streets, especially in central Slough, Chalvey and Salt Hill, and in solid-walled terraces the damp proof course may be bridged, failed or missing, which lets genuine rising damp up the wall. Penetrating damp and condensation are common too, so we always confirm the real cause with a survey first.

I keep getting black mould in my Slough flat or rented house. Why?

In Slough's flats, converted houses and shared or multi-occupied homes, most black mould is condensation, not rising or penetrating damp. Warm, moist air from cooking, washing and drying, with not enough ventilation, settles on cold surfaces and grows mould in corners and around windows. The fix is usually the right ventilation and insulation rather than a damp proof course, and a survey identifies what is needed.

Could the gravel and clay ground be causing my damp?

It can contribute. Slough sits on Thames river-terrace gravels over London clay, with lower ground near the Thames and the Jubilee River. Water can sit in the gravels above the clay and a higher water table in low-lying spots can push ground moisture into floors and walls. We check the ground conditions as part of the survey rather than assuming every damp wall is rising damp.

How much does damp proofing cost in Slough?

It depends on the cause, how much of the property is affected, access, and whether replastering or waterproofing is needed, so there is no honest one-size figure. After a survey we provide a clear, itemised written report so you know exactly what the work involves and what it costs before deciding anything.

Is the work guaranteed?

Yes. Our installed damp proofing and waterproofing work is backed by a written 10 year guarantee, which is transferable if you sell and is accepted by solicitors and lenders during a sale.
