Services
Damp Proofing
Our damp proofing solutions address rising damp through chemical damp courses and waterproof rendering systems. With 40 years of expertise, we guarantee treatments for 20 years, using salt-retardant plasters to prevent recurrence. Our fixed-price quotations ensure transparency, and our proprietary Kenwood Damp-Proofing Waterproof Rendering System eliminates hygroscopic salts that cause damp walls. This service protects properties from structural damage while maintaining habitable conditions.
Basement Tanking
Kenwood Damp-Proofing's basement tanking systems create watertight environments using SWS and Rapid Setting compounds. These solutions withstand hydrostatic pressure in below-ground spaces, with 10-year guarantees. Our cavity drain membranes and positive pressure ventilation systems prevent water ingress in existing basements and new constructions, transforming damp cellars into usable living or commercial areas.
Woodworm Treatment
We eradicate wood-boring beetles through targeted insecticidal treatments that penetrate deep into timbers. Our solutions address common furniture beetle, death watch beetle, and lyctus infestations, with guarantees up to 20 years. The process involves exposing subfloor timbers for thorough treatment, allowing reoccupation within one hour due to our low-odour preservatives.
Condensation Control
Our condensation control systems use automated humidity-controlled extractors and heat recovery units to maintain air quality. The Kenwood Damp-Proofing Positive Pressure Ventilation System introduces filtered air while displacing moisture-laden air, preventing mould growth in residential and commercial properties. These low-energy solutions operate unobtrusively with minimal tenant interaction.
Specialist Replastering
Following damp proofing, our premixed waterproof rendering system replaces salt-contaminated plaster. This factory-blended solution with polypropylene fibres ensures consistent quality and eliminates shrinkage risks. Unlike site-mixed renders, our system guarantees a dry internal finish without additional charges for plaster thickness variations during the replastering process.

Kenwood recently completed damp-proofing a couple of walls in my kitchen and from Nick who made the initial site visit to Jim in the office and then all in the office who were most helpful. In particular Lewis & Stan who carried out the work very efficiently and left the job as clean as when they started. Very impressed all round.

Report
Delighted with the support received from Kenwood Damp Proofing. They were quick to respond and undertake a survey of our house. The surveyor explained everything as he undertook the survey and followed up with a clear report that identified cause and cure. Ive contracted with them to undertake the necessary work and delighted that I only have to wait a few days to get it sorted. Full marks to Jim OMalley and his colleagues, we couldnt have asked for better support and their price isnt bad either.
