How does subsidence cause damp problems?

Subsidence movement can crack or displace physical damp-proof courses, open up mortar joints allowing rain penetration, damage cavity trays above windows and doors, and disrupt below-ground drainage that normally keeps groundwater away from foundations.

What types of damp treatment are available?

Treatments include chemical damp-proof course injection, physical DPC installation, external waterproofing, internal tanking, improved ventilation, cavity drain membranes, and drainage improvements. The right treatment depends on the type of damp and the building construction.

How much does damp proofing cost in St Austell?

Costs depend on the type and extent of dampness. Chemical DPC injection typically costs £1,500-£4,000 for a standard terraced house. More extensive treatments involving tanking or external waterproofing can cost significantly more.

Can damp cause structural damage?

Yes. Persistent dampness can deteriorate timber structural elements (causing rot), corrode embedded metals (including wall ties and lintels), and weaken mortar joints. Over time, this can compromise the structural integrity of the building.

Is damp proofing covered by insurance?

Damp proofing itself is not usually covered by standard buildings insurance. However, if the damp is caused by an insured peril (such as escape of water from a defective drain, or structural damage from subsidence), the repair costs may be covered.
