Damp Proof Course (DPC) – Frequently Asked Questions
What is a damp proof course (DPC)?
A damp proof course is a protective barrier installed within a building’s structure to prevent moisture from travelling through walls and floors. It helps stop rising damp and protects internal surfaces from water damage.
How do I know if my property needs a new DPC?
Signs that a damp proof course may be required include damp patches on lower walls, peeling paint or wallpaper, crumbling plaster, and white salt deposits on brickwork. A professional damp survey is the best way to confirm the cause.
Can a damp proof course fail over time?
Yes, older properties may have a DPC that has deteriorated, been bridged, or was never installed correctly. When this happens, moisture can begin to move through the structure, leading to rising damp issues.
What is the most common type of damp proof course?
The most widely used modern solution is a chemical injection DPC, where a specialist cream is injected into the wall to create a water-resistant barrier. This method is effective, minimally invasive, and suitable for most properties.
Is a damp proof course the same as damp proofing?
Not exactly. A damp proof course is one element of damp proofing. Damp proofing as a whole can include ventilation improvements, membranes, waterproof coatings, and other treatments depending on the type of damp present.
How long does a damp proof course last?
When installed correctly, a damp proof course can last for many years. Many systems come with long-term guarantees, providing reassurance that the treatment will continue to protect the property.
Do all damp problems require a DPC?
No. Not all damp issues are caused by rising damp. Condensation and penetrating damp are often mistaken for it. That’s why a proper diagnosis is essential before any work is carried out.
