20 year damp proof guarantees

A guarantee from Kenwood Plc is a guarantee of quality and reliability which home owners and property professionals know and trust.

You can be confident that Kenwood Plc complete works to the highest standards and offer genuine guarantees that ensure if our work is faulty in anyway, it will be rectified free of charge. Our pedigree is your guarantee of excellence.


Typically, our damp proofing, woodworm and dry rot treatments are guaranteed for 20 years and our tanking and structural waterproofing for 10 years.

Our experience, expertise and quality systems ensure that our installations are carried out effectively, to high standards and our reputation for reliability is second to none.

We have been established for over thirty years and our treatments are carried out exclusively by our own skilled operatives, experienced in this type of work, not sub contractors.

This confidence in our works allows us to offer genuine long-term guarantees.

Kenwood’s SWS Tanking System©, unlike many waterproofing systems, does not require a sump pump. This has the benefit that the guarantee is not conditional upon an ’on going’ maintenance contract or servicing arrangements, which are typically required with a cavity drain membrane system.

Additionally, we offer a range of insurance products for your peace of mind, including guarantee insurance through the market leading insurers.
