Damp Proofingfor Landlords & Rental Properties
Rising and penetrating damp treatment and prevention
Quick answer
Damp proofing is the treatment of rising damp or penetrating damp in a building to prevent moisture from entering the fabric of the property. It includes chemical injection damp-proof courses for rising damp, external renders and water-repellent coatings for penetrating damp, and remedial pointing for deteriorated mortar joints.

Rising damp and penetrating damp cause structural damage over time — staining, plaster failure, timber rot, and eventually damage to floors and structural elements. For landlords, damp proofing is a fabric investment that protects the property value while ensuring the property remains habitable. Untreated damp is an HHSRS hazard and a potential Awaab's Law trigger.
What Should You Expect?
Damp proofing works depend on the diagnosis. Rising damp treatment typically involves injection of a chemical damp-proof course, replastering with salt-resistant render, and skirting board replacement. Penetrating damp treatment may involve re-pointing, external waterproof coatings, repair of failed lead flashings, or gutter and downpipe repairs. Always ensure the cause is correctly diagnosed before any treatment begins.

Frequently Asked Questions About Damp Proofing
- How do I know if my property has rising damp or penetrating damp?
- Rising damp typically presents as a 'tide mark' on lower walls, often with salt staining and plaster blow. It rarely rises above 1.2m from floor level. Penetrating damp appears as wet patches on walls or ceilings, often associated with rainfall, and can appear at any height. Condensation mould, often confused with damp, appears on cold surfaces and worsens in winter. An independent damp survey will distinguish between these causes.
- Is damp proofing a permanent fix?
- Chemical injection damp-proof courses are designed to last the life of the building, but their effectiveness depends on the quality of installation and subsequent replastering. External waterproof treatments and coatings may need reapplication after 10–15 years. Pointing repairs are durable if done with appropriate mortars.
- What guarantees should I get from a damp proofing contractor?
- Reputable damp proofing contractors provide guarantees of 20–30 years on chemical damp-proof course installation. PCA member companies back these guarantees with deposit protection insurance, so the guarantee remains valid even if the company ceases trading. Always ensure guarantees are in writing.
