How to fix penetrating damp?

• DIY Solutions

If you’re handy and have some basic home improvement skills, there are a number of DIY solutions to fixing penetrating dampness. These include:

• Repairing Damaged Roof Tiles or Gutters: One of the most common causes of penetrating dampness is damaged roof tiles or gutters. To fix this issue, you can repair or replace any damaged or missing tiles or gutters. 
• Applying a Waterproof Coating: If you have minor cracks or gaps in your walls or floors, you can apply a waterproof coating to prevent moisture from entering. This is an affordable and easy solution, but it may not be effective for more serious penetrating damp problems. 
• Installing a Damp-Proof Course: If you’re dealing with rising dampness, you can install a damp-proof course to prevent ground moisture from entering the building. This is a more complex DIY solution and may require professional assistance. 

• Professional Solutions

If you’re dealing with a serious penetrating damp issue, it’s best to seek the help of a professional. Professional solutions to fixing penetrating dampness include:

• Replacing Damaged Roof Tiles or Gutters: If your roof tiles or gutters are severely damaged, a professional may recommend replacing them.
