Damp Proofing Pinner
Pinner pairs one of the most intact old village centres in north west London with the Metro-land semis it helped invent, and the two need very different treatment. We diagnose the real cause, penetrating damp, condensation or rising damp, and put it right. Survey-led, with a written 10 year guarantee.

Damp in Pinner Homes
Pinner has a split personality when it comes to property. Most of its housing is interwar Metro-land, in fact Cecil Park, laid out from around 1902, is often called the first piece of Metro-land England ever built, the prototype for the semis that went on to cover north west London. In those cavity-walled houses the problem is rarely classic rising damp. Far more often it is penetrating damp through bays, render and bridged cavities, or condensation and black mould once newer windows have cut the ventilation right down.
Then there is the village itself, one of the best-preserved old centres in the area. Around the sloping High Street and the flint church there are timber-framed buildings, conservation areas and many listed homes, plus the white-rendered Art Deco flats of the 1930s. Solid-walled, flint and timber-framed property like this needs a breathable approach, not the cement renders and waterproof plasters that trap moisture in old fabric, while rendered Art Deco blocks tend toward render cracking and condensation.
Underneath it is mostly London clay, which drains poorly and shifts with the seasons, with gravels capping Pinner Hill and historic chalk workings below ground. Homes low down near the River Pinn, which runs through the village and is culverted in places, can also see a higher water table. With that range of property and ground, the only reliable starting point is a proper survey.

Penetrating Damp
Damp driven through bays, render and clay-cracked walls, the most common issue in Pinner's Metro-land semis.

Black mould in sealed semis and Art Deco flats, cured with the right ventilation rather than a damp proof course.
