Frequently asked questions about Damp Treatment Guarantee

Is a PCA guarantee needed for a mortgage?
If damp or timber issues are identified in a survey, most mortgage lenders will require treatment by a PCA member (or equivalent) with an insurance-backed guarantee before releasing funds.
How long does a damp guarantee last?
Typically 10 years for chemical DPC injection and timber treatment, 20-30 years for some specialist treatments. Insurance-backed guarantees can be transferred to new owners if the property is sold.
