How Much is a Damp-Proof Course?

How much is a damp-proof course? This is something that every homeowner should know, as it can help keep your home in good condition and prevent future problems. Knowing the ballpark price for a damp proof course will also help you to avoid paying over the odds if you ever need to call in the professionals.

A damp proof course (DPC) is a layer of material that helps to prevent moisture from entering your home. It is typically installed at the base of walls or between floors. The specialist foam is inserted into the wall through drilled homes and then left to seep out to create an impermeable layer within the wall.

The cost of a damp proof course will vary depending on the size and type of your home, but it is generally quite affordable. If you are concerned about moisture damage to your home, then installing a DPC can be a great way to protect it.

What is a damp-proof course? 

A damp proof course, or DPC, is a barrier in a building’s structure that helps stop moisture from rising due to capillary action. This can be an extremely important feature for homeowners; without a damp-proof course, moisture could enter your home through walls and undermine the structure of the building. It can penetrate wooden floors, ruin insulation and lead to musty odours in your rooms. 

Why do you need one in your home?

Installing a damp-proof course during construction will help protect your family from the potentially harmful effects of rising damp. In some cases, it may be necessary to undertake remedial treatment such as tanking if no DPC was included during construction, or if it is proven not to be working effectively. For these reasons, it is important to make sure there is an effective and well-functioning damp-proof course in your home.

How much does a damp proof course cost?

A damp proof course, or a DPC, is an important waterproof barrier used in the construction of buildings to prevent moisture from rising through the walls and floors. On average, a damp proof course can cost around £80-£160 per metre. 

Factors that can affect the cost may include location, quality of material and external costs like scaffolding or labour fees. The installation of a damp proof course is highly recommended for foundations built with porous materials like brick, block or mortar as well as on properties that are situated in high water exposure areas. 

To ensure you get the best quality job done at an affordable price it pays to shop around for quotes from trusted local contractors who understand your area’s regional climate-related moisture issues.

Can DIY a damp-proof course installation?

While it is possible to DIY a damp-proof course, it’s usually best to leave this to the professionals. You can find DIY kits that will enable you to drill the holes and insert the chemical treatment yourself. However, this can be a daunting task, particularly if your existing damp-proof course has failed.

If you do decide to complete your own damp-proof course, you’ll need to complete the following steps. You’ll start by drilling 12mm holes around 90% into the wall and then inject with damp-proof course cream. You’ll need to measure the distances to ensure you get adequate coverage.

Your DIY damp-proof course kit should include instructions for ensuring full coverage. With these easy steps, you’ll be well on your way to DIYing a damp-proof course installation successfully.

What are the signs a damp-proof course has failed?

It can be tricky to know when it is time to call in a professional for help with your damp proof course, but there are certain signs you should look out for. A telltale sign is if you have slowly started to notice a persistent damp scent or condensation forming along walls, this could mean that water has found its way into the property due to undetected cracks which will require a professional’s help. 

Similarly, if you’ve noticed signs of peeling wallpaper and discolouration spots around your walls (along with the ever-present musty smell), this could suggest that there is an issue with your damp proofing. In any case, enlisting a trained expert with experience in identifying potential problems and carrying out appropriate repairs will ensure the safety and structural integrity of your home over time.

Conclusion

A damp-proof course is an essential element in any home, and can be the difference between a dry, comfortable home and one that is damp, mouldy, and unpleasant. Damp-proof courses are not expensive, and can often be installed by homeowners themselves. However, there are some cases where it is best to call in a professional for help. Knowing when to DIY and when to call in a pro will save you time, money, and effort in the long run.
