Understanding Damp in Warrington Homes
Damp is one of the most misunderstood property issues, especially in older homes across Warrington. Homeowners are often told they need a full damp proof course (DPC) installation, when in fact the issue could be something far simpler—bridging plaster.
So, how do you tell the difference?
What Is Bridging Plaster?
Bridging occurs when internal plaster makes direct contact with the floor, effectively "bridging" over the existing DPC. This allows moisture from the floor slab or subfloor to rise up behind the plaster, mimicking the symptoms of rising damp.
Unlike true rising damp, this type of moisture issue usually shows:
-
Damp staining confined to the lower wall (often below skirting level)
-
No visible salts or musty smells
-
A solid existing DPC in place
In many cases, removing just enough plaster behind the skirting board to eliminate the bridge resolves the issue. There's no need to remove plaster up to 1 metre high unless there's salt contamination or other damage.
When Is a New DPC Necessary?
A new damp proof course is typically only needed if:
-
The original DPC has failed or is missing
-
There’s salt contamination in the wall fabric
-
The wall construction does not include a physical DPC
-
There’s ongoing moisture ingress not explained by bridging
Our team will always start with a detailed inspection based on previous RICS findings. If bridging is confirmed, we can simply remove the affected plaster, allowing the wall to dry naturally.
Insurance-Backed Protection at No Extra Charge
If we carry out bridging removal, we offer the option to upgrade the wall with a chemical-free silicone DPC application at no additional charge. This gives customers access to an insurance-backed guarantee, offering long-term peace of mind and certification for mortgage purposes.
