Damp Proofing Ickenham

Ickenham mixes interwar Metro-land semis off the old Swakeleys estate with a genuinely old village core and property along the River Pinn, and each throws up different damp problems. 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 Ickenham Homes

Ickenham was a tiny farming village until the railway arrived, and then in 1922 most of the Swakeleys estate, well over a thousand acres, was auctioned for housing. The streets that followed, off Swakeleys Road and Long Lane, filled with the red-brick, tiled-roof semis that define the area today. In those interwar 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.

But Ickenham kept its old heart, and that is the other side of the work. Around St Giles' church, the village pond and the pump, there are restored 14th, 15th and 16th-century buildings, and Grade I listed Swakeleys House sits close by. Solid-walled and timber-framed property like this needs a breathable approach, not the cement renders and waterproof plasters that trap moisture in old fabric.

Underneath nearly all of it is heavy London clay. Ickenham is notably flat, the clay drains poorly and shifts with the seasons, and a low strip of alluvium runs along the River Pinn to the west and the Yeading Brook to the east, where ground damp is more likely. With that range of property and ground, the only reliable starting point is a proper survey.

Damp Proofing Services in Ickenham

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 bays, render and clay-cracked walls, the most common issue in Ickenham's interwar semis.

Condensation & Mould

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

Rising Damp

Genuine rising damp in older village-core and Pinn-side property, treated with a new damp proof course where confirmed.

Timber & Rot

Woodworm, dry rot and wet rot in the timbers of period and timber-framed homes around the old village, treated at the cause.

Waterproofing

Structural waterproofing and tanking for cellars and ground floors on flat clay and near the River Pinn.

Damp Surveys

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

Damp Proofing Ickenham FAQs

Which parts of Ickenham do you cover?
All of Ickenham and the surrounding Hillingdon area, including the village centre and pond, Swakeleys, Ickenham Green, the streets off Swakeleys Road and Long Lane, Ickenham Marsh, and neighbouring West Ruislip, Ruislip, Uxbridge, Hillingdon and Harefield.
I have damp in a 1930s semi off Swakeleys Road. Is it rising damp?
Usually not. Much of Ickenham was built after the Swakeleys estate was auctioned for housing in 1922, so most of its stock is interwar cavity-walled semis. These far more often suffer penetrating damp through bays, render and bridged cavities, or condensation once double glazing has reduced ventilation, than genuine rising damp. We confirm the real cause with a survey before recommending anything.
Can you work on the older homes around the village and St Giles' church?
Yes. The old core of Ickenham around St Giles' church and the village pond has restored period and timber-framed buildings, and Swakeleys House nearby is Grade I listed. Old fabric like this needs a breathable approach. Cement renders and modern impervious plasters trap moisture and make damp and timber decay worse, so we use sympathetic, appropriate repairs and treat the cause.
Could the clay and the River Pinn be causing my damp?
They can. Ickenham is flat and sits almost entirely on London clay, which drains poorly and shrinks and swells with the seasons, cracking walls and render so water tracks in. There is also a strip of low-lying alluvium along the River Pinn to the west and the Yeading Brook to the east, where the water table is higher and ground damp is more likely. A survey establishes which is at work.
How much does damp proofing cost in Ickenham?
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.
