Extending a Rising Damp Treatment on Priory Road, South Hampstead NW6
Advanced Damp had already treated rising damp at this property on Priory Road in South Hampstead. On a second phase visit, the treated walls were dry, but moisture was showing just beyond the edge of the original work.
Project at a Glance
The Brief
This was a phase two visit to check the first treatment and look at damp the owner had noticed in nearby walls.
The Survey
The surveyor confirmed the first rising damp treatment had worked in the areas it covered.
Moisture had, however, been found beyond the original treatment boundary. Readings were 52.4 percent wood moisture equivalent by the kitchen doorway, 23.3 percent in the kitchen wall and 18.3 percent in the dining room wall.
The Solution
Extend the treatment to the newly affected walls:
- Hack off the contaminated plaster.
- Install a damp proof course.
- Apply render and a set coat finish.
The Work
The extension work was completed over two days.
The Result
The whole run of affected wall is now treated, joining up with the original work. Moisture can track sideways along a wall to the edge of a treated area, so a follow up check like this is worthwhile. See our page on damp proofing in Kilburn.
Frequently Asked Questions
Why has damp appeared next to a treated wall?
Ground moisture can move sideways to the nearest untreated section. Extending the treatment closes that gap.
What does WME mean?
Wood moisture equivalent is a standard scale used by damp meters. Higher numbers mean wetter masonry.
Is a follow up visit worth it after damp treatment?
Yes. It confirms the treated areas are drying and picks up any nearby walls that need attention.
