Damp Proofing Tunbridge Wells

Tunbridge Wells is built on sandstone and clay, on steep Wealden slopes where springs and seepage are part of the ground itself, so its Regency villas, grand Victorian houses and hillside cellars get a particular kind of damp. We diagnose the real cause and put it right. Survey-led, with a written 10 year guarantee.

Damp in Tunbridge Wells Property

To understand damp in Tunbridge Wells you have to start with the ground. The town sits on the High Weald, on the Tunbridge Wells Sand, the same sandstone you can see breaking the surface at Wellington Rocks and Toad Rock, laid over a band of impermeable Wadhurst Clay. On the steep slopes the town is built across, water soaking down through the porous sand is forced out where it reaches the clay, as spring lines and seepage. The chalybeate spring that founded the town is one of them.

For property that means hillside ground damp and penetrating damp, and in homes with cellars cut into the bank, below-ground water that needs proper below-ground waterproofing rather than a damp proof course.

On top of that geology sits the architecture: the solid-walled Regency villas of the Pantiles, Mount Sion and Decimus Burton's Calverley Park, prone to rising and penetrating damp; the grand Victorian houses on the hills; and the tile-hung Wealden cottages of the villages. With that range, a proper survey is the only reliable starting point.

Damp Proofing Tunbridge Wells FAQs

Which parts of Tunbridge Wells do you cover?
All of Royal Tunbridge Wells and the surrounding High Weald, including Southborough, High Brooms, Rusthall, Hawkenbury, Langton Green, Speldhurst, Bidborough, Pembury, Frant and Groombridge, as well as neighbouring Tonbridge.
Why does the geology around Tunbridge Wells cause damp?
It is the thing that sets the town apart. Tunbridge Wells is built on the High Weald, on the Tunbridge Wells Sand, the same sandstone you see at Wellington Rocks and Toad Rock, laid over the impermeable Wadhurst Clay. On the steep slopes, water soaking through the sand is forced out where it meets the clay, as spring lines and seepage. The chalybeate spring that founded the town is exactly that. For property on those slopes it can mean hillside ground damp, penetrating damp and below-ground water in cellars cut into the bank, which needs proper waterproofing rather than a damp proof course. A survey confirms it.
Can you work on the Regency and period homes around the Pantiles and Calverley Park?
Yes. The spa-town core around the Pantiles, Mount Sion, Mount Ephraim and Decimus Burton's Calverley Park villas is largely solid-walled and rendered, much of it listed and in conservation areas, and some homes are built of the porous local sandstone. A bridged or failed damp proof course lets rising damp up, and driving rain crosses solid walls as penetrating damp. Old fabric needs a breathable approach, so we confirm the cause and repair sympathetically.
I have a Victorian villa on a slope with a damp cellar. Can you help?
Yes, and it is common here. The railway-era villas were built up the contours, often with lower-ground rooms or cellars cut into the sand and clay slope, so they can take in below-ground water and spring-line seepage from the bank behind. The answer is proper below-ground waterproofing or tanking to BS 8102, designed for that slope, not a chemical damp proof course. We confirm the water path with a survey first.
How much does damp proofing cost in Tunbridge Wells?
It depends on the cause, how much of the property is affected, access, whether it is a damp proof course or below-ground waterproofing, 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.
