Damp Proofing Kew
- Damp proofing carried out across Kew, North Sheen, and the surrounding Thames riverside.
- We establish the cause through inspection, never through guesswork.
- Rising damp, penetrating damp, and condensation are each treated as separate problems.
- Every visit finishes with a clear, written report.
Kew's riverside location, historic homes, and mature gardens can create unique damp challenges. Our surveyors identify whether rising damp, penetrating damp, or condensation is responsible, then recommend the right solution with a written guarantee.

What Kew's Riverside Setting and Deep Gardens Mean for Damp
Ground close to the Thames tends to stay damp for longer after wet weather than land further from the river, and older Georgian and Victorian properties around Kew Green were built with damp-proof courses that simply weren't designed to cope with a century or more of that kind of exposure. Once one of those original courses fails, rising damp is a common outcome, particularly on ground-floor walls closest to street level.
The area's substantial, well-established gardens add a second factor that's less obvious. A wall shaded for much of the day by mature trees and dense planting dries out far more slowly after rain than one that gets full sun, which means render, pointing, and paintwork on garden-facing elevations tend to deteriorate faster and let in penetrating damp sooner than the equivalent street-facing wall on the same house. Add in the humidity that heavy garden planting can hold close to a building, and condensation can also become more persistent in rooms backing onto a shaded garden. A proper waterproofing survey that takes the property's aspect into account is the best way to separate these causes, and where a failed damp-proof course is genuinely to blame, rising damp treatment goes into the plan.
Damp Proofing Services for Kew Properties
Riverside proximity and garden exposure both play a part here, so damp proofing in Kew starts with understanding how a property's setting, not just its age, might be affecting it.
Rising Damp Treatment
Once rising damp is genuinely confirmed in an older Kew property, we install a replacement damp-proof course, only after survey evidence has ruled out other explanations.
Penetrating Damp
Render and point on shaded, garden-facing walls tend to fail faster than on sunnier elevations, and we identify exactly where water is getting in before recommending a repair.
Condensation & Mould
Rooms backing onto dense, mature gardens can hold onto humidity longer than the rest of the house, so improved ventilation is often a more effective fix than an unnecessary chemical damp course.
Timber & Rot Treatment
Older floor joists, roof timbers, and garden-facing window frames across Kew's period housing stock can be affected by rot and woodworm, both treated alongside the moisture causing them.
Basement and Subterranean Waterproofing
Cellars and lower-ground spaces in properties close to the Thames can face a raised water table, particularly after prolonged wet weather. We fit tanking and waterproofing systems designed to withstand sustained hydrostatic pressure.
Damp Surveys
We carry out clear, written damp surveys that are especially useful for anyone buying a period property around Kew Green or a garden-heavy home further into North Sheen.
Three Types of Damp, Three Very Different Behaviours
Rising damp: The slow-moving one. It can take months or years to become noticeable, usually rising no more than a metre from ground level. Look for tide marks, crumbling plaster and white, powdery salt deposits.
Penetrating damp: The reactive one. Often caused by issues such as cracked render, blocked gutters or damaged pointing, it becomes more noticeable when rain reaches the affected wall.
Condensation: The daily visitor. It forms repeatedly on cold surfaces, especially windows and poorly ventilated areas. It improves with better ventilation but returns when moisture builds up again.

How a Damp Survey and Repair Works in Kew
Arranging a Visit
We arrange the visit around your schedule, whether you're around Kew Green, closer to the river, or further out towards North Sheen.
Pinpoint the Actual Cause
Moisture readings and thermal imaging are taken with the property's orientation in mind, since a shaded garden wall can behave very differently to a sunlit street frontage on the same house.
A Report You Can Actually Understand
You'll receive a written report covering the likely cause, the recommended treatment, and a realistic cost, with consideration for how riverside ground and mature gardens can influence a property.
Complete the Treatment
Our technicians complete treatment efficiently and tidily, keeping disruption to your household to a minimum, including care around established garden planting where relevant.
Guarantee in Writing
Once the job's finished, the guarantee remains valid for its full term and transfers automatically if you sell the property.

What Kew Homeowners Say About Us
Genuine reviews from Advanced Damp customers.
“Our garden wall backs onto some very established planting and had developed damp we assumed was rising damp. Advanced Damp explained it was actually the shade keeping the render wet for too long after rain, and the fix made complete sense.”
“Living so close to the river, we were half expecting the worst, but the survey found a straightforward render issue rather than anything to do with the Thames. Quick, honest, and reasonably priced.”
“Had a pre-purchase survey done on a house near Kew Green and they were incredibly thorough about both the front and garden elevations. Gave us real confidence before we committed.”
Restoring a Damp-Damaged Property
Restoring a Dry, Healthy Home
Severe moisture had caused significant damage to the walls of this North West London property. After a thorough inspection, we identified the underlying cause and implemented a tailored damp-proofing solution. Damaged surfaces were removed and restored, leaving the property dry, healthier, and with improved wall condition.

Kew Damp Proofing FAQs
Does living so close to the Thames automatically mean a higher risk of rising damp?
Can shade from garden trees really affect damp on a wall, or is that overstated?
Our house is close to Kew Green and may be listed; does that limit what treatment can be used?
We've got a large, well-established garden, could that be affecting drainage around the house?
What should I expect to pay for damp proofing work in Kew?
If we sell the house later, does the guarantee still cover the new owners?
