Rising Damp Treatment in Liverpool: What’s Involved and How Long Does It Take?

Rising damp treatment in Liverpool is needed when groundwater travels up a wall by capillary action. This usually happens because the damp-proof course is missing, damaged or bridged. As a result, you will often see staining, crumbling plaster or a tide mark on internal walls near ground level.

How We Diagnose Rising Damp

Before recommending any work, we confirm that rising damp is actually the cause. Condensation and penetrating damp can look similar, but they need very different fixes. For that reason, our survey includes:

  • Moisture readings at different heights on the affected wall
  • An inspection of the existing damp-proof course, if one is present
  • Checks of external ground levels and paths for bridging
  • Ruling out plumbing leaks and penetrating damp as the real cause

What Does Rising Damp Treatment in Liverpool Involve?

Once we confirm the diagnosis, rising damp treatment in Liverpool typically includes the steps below. The Wikipedia guide to damp proofing explains how a damp-proof course works in more detail.

  • Installing a new chemical damp-proof course by injection
  • Removing affected plaster and replacing it with a suitable renovation plaster or render
  • Fixing external issues, such as high ground levels, that are bridging the damp-proof course
  • Redecorating once the walls have fully dried out

How Long Does Rising Damp Treatment in Liverpool Take?

Injecting a new damp-proof course and replastering usually takes a few days, depending on the size of the affected area. However, the walls need time to dry out before you decorate. In fact, this can take several weeks to a few months, depending on wall thickness and the time of year. Before work starts, we always give you a realistic timeline.
