With nearly 40 years of experience our guarantees have a long pedigree. Our current guarantee periods are: - 

• DPC – 20years
• Timber treatment – 20years
• Structural waterproofing – 10 years

Ward Damp-Proofing Ltd has been successfully trading since 1977 and is pleased to offer additional protection for treatment guarantees in the unlikely event that the company ceases to trade. 

All of our guarantees can also be insured for a period of 10 years by Guarantee Protection Insurance Limited (GPI), upon payment of the applicable premium.

An insurance backed guarantee is available on both residential and commercial premises, however they apply for each individual property (i.e. if a property consists of two flats and each need a guarantee then two Insurance Backed Guarantees will need to be applied for), this also applies per treatment i.e. if you have a damp proof course and timber treatment you will need to purchase a policy for each treatment.

If you have any queries about the cover provided by an Insurance Backed Guarantee, please direct to GPI by telephoning during office hours 01292 268 020 (option 5), sending them an e-mail at or by visiting their website
