Damp in Enfield Homes

Enfield is a borough of very mixed housing, and each type brings its own damp. The older solid brick Victorian and Edwardian terraces, around Bush Hill Park, Ponders End, Edmonton and Palmers Green, can suffer genuine rising damp where the damp proof course has failed, along with penetrating damp through worn pointing and render.

Much of the rest of the borough went up in the 1920s and 1930s, when the railways and the Piccadilly line out to Cockfosters turned farmland into suburb almost overnight. Those cavity-walled semis in Southgate, Winchmore Hill, Grange Park and across Enfield are more prone to penetrating damp through flat roof defects, leaking bays and bridged cavities, or to condensation once double glazing has cut their ventilation. And because so much of Enfield sits on London clay, seasonal shrink and swell cracks walls and lets water track in, a very common north London problem.

To the east, around Ponders End, Enfield Lock and the Meridian Water regeneration, the ground drops into the low-lying Lea Valley, with the River Lea and the New River close by, so a high water table can bring ground damp to floors and cellars. With this range of property and ground, the only reliable starting point is a proper survey.

Damp Proofing Services in Enfield

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, render and clay-cracked masonry, the most common issue in Enfield's terraces and 1930s semis.

Rising Damp

Genuine rising damp in the borough's older solid brick terraces, treated with a new damp proof course where a survey confirms it.

Condensation & Mould

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

Waterproofing

Structural waterproofing, tanking and cavity drain membranes for cellars and ground floors in the low-lying Lea Valley.

Timber & Rot

Woodworm, dry rot and wet rot in the floor and roof timbers of older and period Enfield homes, treated at the cause.

Damp Surveys

Independent, survey-led diagnosis with a clear written report, ideal for homebuyers and pre-purchase building surveys.

Damp Proofing Enfield FAQs

All of the borough, including Enfield Town, Bush Hill Park, Ponders End, Enfield Lock, Enfield Highway, Edmonton, Palmers Green, Winchmore Hill, Southgate, Grange Park, Cockfosters, Hadley Wood and Forty Hill.

I have damp in a 1930s Enfield semi. Is it rising damp?

Usually not. Enfield expanded hugely in the 1920s and 1930s, and those cavity-walled semis far more often suffer penetrating damp through flat roof defects, leaking bays, tired render and bridged cavities, or condensation after double glazing has reduced ventilation. Genuine rising damp is more typical of the older solid brick terraces. A survey confirms the real cause before any treatment.

Could cracking from London clay be causing my damp?

It can. Much of Enfield sits on London clay, which shrinks and swells with the seasons and is one of the most common causes of cracking in north London homes. Cracks in walls and render let water track in, showing up as penetrating damp. We identify where water is getting in and address the defect, not just the damp patch.

Does being near the River Lea or the New River cause damp?

It can. The east of the borough, around Ponders End, Enfield Lock and the Lea Valley, is low-lying former industrial and riverside land with a high water table, and the New River also runs through Enfield. Homes on this ground can take in ground damp through floors and cellars. A survey establishes whether the water is coming from the ground, the structure or the air inside the home.

How much does damp proofing cost in Enfield?

It depends on the cause, how much of the property is affected, access, and whether replastering 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.
