Our Guarantee

For your peace of mind: guarantees among the longest in the industry

What matters most is that your damp-proofing lasts. Our workmanship is excellent and our call-out rate tiny — but a guarantee is paramount, so once we’ve completed a job we give you a rock-solid one.

No quibbles — we always honour them

In the unlikely event anything goes wrong during the guarantee period, we’ll come back and fix it at no cost to you.

Underwritten by GPI insurance

Our guarantees can be underwritten by General Protection Insurance — so even if Dampcoursing Ltd ceased trading, you’d be covered.

Fully transferable

If you sell your property, the guarantee transfers to the new owners — invaluable when buyers and lenders are wary of damp.

Here for the long term

We’ve operated successfully since 1957 — much longer than most firms — and we plan on being around for a long time to come.

Avoid problems when you sell

Potential buyers are wary about damp. With our guarantees in place you can demonstrate that everything has been comprehensively dealt with, and that the new owners are fully covered — alleviating buyers’ concerns and making the sale much easier.

The point is simple: we want you to be completely satisfied with the damp-proofing we install, with the added peace of mind of some of the longest guarantees around.
