Damp Proofing Greenford
Greenford is a 1930s suburb, and its cavity-walled semis throw up very different damp problems to its older period homes and canal-side flats. We diagnose the real cause, penetrating damp, condensation or genuine rising damp, and put it right rather than guessing. Survey-led, with a written 10 year guarantee.

Damp in Greenford Homes
Greenford changed from a farming village into a west London suburb in the great speculative building boom of the 1920s and 1930s, and that history shapes its damp. Most of the housing here is interwar semi-detached, terraced, bungalows and maisonettes, with cavity walls. In that stock the problem is rarely classic rising damp. Far more often it is penetrating damp through bridged or failed cavities, leaking bays and tired render, or condensation and black mould once double glazing and draught proofing have cut down the ventilation these homes were built to rely on.
There is an older Greenford too, around Holy Cross Church and Oldfield Lane, with some solid brick period property that can suffer genuine rising and penetrating damp and needs a breathable approach. And there is the water: the River Brent and the Grand Union Canal run through the low-lying middle of the area, historically prone to flooding, so homes near them can have a high water table and ground damp.
Add the canal-side and ex-industrial sites now being converted to flats, where sealed, airtight construction brings condensation, and Greenford becomes a place where the symptom on the wall rarely tells you the cause. That is why we always start with a proper survey.
Damp Proofing Services in Greenford
Whatever the property and whatever the cause, we cover it, and we link each job to the right specialist treatment.
Penetrating Damp
Damp driven through walls, bays and failed render, the most common issue in Greenford's ageing 1930s cavity-walled semis.
Condensation & Mould
Black mould in sealed, under-ventilated semis and modern flats, cured with the right ventilation rather than a damp proof course.
Rising Damp
Genuine rising damp in the area's older solid brick period homes, treated with a new damp proof course where a survey confirms it.
Mould Removal
Safe removal of black mould, paired with fixing the underlying damp so it does not simply return.
Waterproofing
Structural waterproofing and tanking for cellars and ground floors near the Brent and the Grand Union Canal.
