Damp Proofing and Waterproofing Contractors

Damp-proofing is the term normally used for controlling lateral or rising damp through building fabric. Water-proofing is the control of water through building fabric. The methods of control for damp and water are generally different. However water-proofing can often be effective damp-proofing. It is the location within the structure that determines whether the problem is damp or water related. As a rule of thumb damp-proofing is associated with ground level or above ground level building and waterproofing below ground level building. Waterproofing systems can also be applied to flat roofs, bridge decks etc subject to rain water penetration.

Damp-proofing in buildings is commonly controlled by damp proof courses in walls and damp proof membranes under floors. However where walls are in contact with earth above damp proof courses, dpc’s become ineffective. Damp proof renders specialist plasters or membranes are required for long term protection.

Insured Guarantees

Formed as the GPT (Guarantee Protection Trust) in 1983, Guarantee Protection Insurance Ltd (GPT) provides Insurance cover which is only offered by Specialist Approved Contractors who are selected to offer Insured Guarantees.

Guaranteed Protection Insurance Ltd (GPI) offer insurance certificates for a period of 10 years, starting from the completion date works were carried out. Unlike other Insurance Policies, GPI cover relates to the property rather than the owner, so if you decide to sell your property the cover is automatically transferred free of charge to the new owners. The Insurance comes into force if your contractor is no longer trading and covers his liability to you ( subject to GPI terms and conditions).

The GPI is a Financial Services Authority (FSA) regulated company.
