A damp proof course (DPC) is a type of damp proofing treatment. It’s designed to prevent water or moisture from entering your property and creating a damp problem.
If there’s evidence of damp in your home or there are signs that your property is susceptible to it, you might need a damp proof course installed in your home. Keep reading to find out about how a damp proof course works and how it could benefit your home.
Why is damp proofing important?
It’s really important to prevent water or moisture from getting into your home. It can lead to damp, mould and mildew growth, which are unsightly health risks. It can also cause structural damage, which is dangerous and can seriously devalue your home.
If your home was built in the 1950s or later, the chances are that it has some kind of damp proof course already. If it’s older, then it might not have one. There’s also the chance that the damp proofing in your home has deteriorated and is no longer working.
How can I tell if there’s damp in my home?
There are quite a few signs that your property might have a damp problem. These include:
- Salt staining
- Discoloured walls, floors or ceilings
- Crumbling plaster
- Peeling wallpaper or paint
- Decaying floors or skirting boards
If you notice any of these signs, you should get a damp proofing professional in to inspect your home.
How does a damp proof course work?
A damp proof course works by creating a barrier between the ground and your walls and floor. This is often a chemical course, which is made out of a water-based silicon fluid. You can use other materials, although these aren’t always as effective. A professional can fit this just above ground level in your walls and under your floors to prevent moisture from traveling through the ground and up into your home.
How do I know if a damp proof course is the best way to damp proof my home?
The best way to find out whether a damp proof course would benefit your property is to speak to a professional. They will inspect you property and be able to tell you what kind of damp proofing you have already, if any. They’ll also be able to recommend any types of damp proofing you might need.
