Damp Proofing Guarantees

Timkon Services offer a 20 Year Guarantee Certificate for both Rising Damp Treatment & Timber Treatment and this can be insurance backed for a period of 10 Years. The benefit of our Guarantees may be assigned up to 3 months after completion of sale or new ownership following payment of the re-assignment fee. Thereafter the Guarantee will become null and void.


Have you ever wondered whether your guarantee will be honoured in the event your contractor ceased to trade?

Hopefully, your chosen contractor will always be there to respond to any problems that may arise over the period of their guarantee and meet the remedial costs accordingly. However, experience shows that contractors may fail for several reasons, principally financial failure, and will therefore be unable to honour their guarantee. 

If you do not have insurance then you could incur substantial costs in the future if faults arise in the works and the original contractor has ceased to trade.

How it Works

If a defect covered by the contractor’s original written guarantee develops and the original company has ceased to trade, a GPI insurance policy will pay for another contractor to remedy the works. In simple terms GPI insures your guarantee.
