We’re the only damp-proofing company that offers a 50-year guarantee.

Exclusive 50-YEAR guarantee

For your peace of mind: we guarantee our work for years

What’s most important to you is that any damp-proofing work lasts.

The turmoil involved in putting things right can be huge. Rest assured, our work is of excellent quality and our call-out rate to fix things is tiny. That said, a guarantee is of course paramount.

Once we’ve completed a job for you, we’ll give you a rock-solid guarantee.

And our guarantees are among the longest in the industry.

In fact we’re the only damp-proofing company that offers a 50-year guarantee.

We’re happy to do this because we’re so confident in the high standard of our workmanship. We know our work lasts.

And in the unlikely event that anything does go wrong during the guarantee period, we’ll come back and fix it at no cost to you.

No quibbles. We always honour our guarantees.

Here’s how long your damp-proofing will be covered by us:

In addition, our guarantees can be underwritten by General Protection Insurance (GPI).

This means that if Dampcoursing Ltd ceases trading, you’ll be covered by additional insurance protection.

Just to say: we’ve been operating successfully since 1957 – much longer than most other firms – and we’re planning on being around for a long time to come!

If you’d like it, this additional level of insurance gives you even more security.

Avoid problems with selling – our guarantees are transferrable

And if you end up selling your property, our guarantees are transferrable to the new owners.

This can be invaluable to you.

​Potential buyers will be wary about damp issues. But with our guarantees in place you’ll be able to demonstrate that everything has been comprehensively dealt with, and that the new owners are fully covered.

This will alleviate the concerns of interested buyers and make selling much easier.

The point is: we want you to be completely satisfied with the damp-proofing measures we install for you.

You can have confidence in our expert work, with the additional peace of mind of knowing that everything is covered by some of the longest guarantees around.

We look forward to hearing from you. Thank you very much for your interest.
