Penetrating Damp Treatment in Canton

Penetrating damp is caused by water entering a building horizontally through defects in the external envelope — cracked render, failed pointing, leaking gutters, defective flashings, or around window and door frames. Unlike rising damp, it can appear at any height and often worsens in wet weather. EverDry Damp carries out a systematic external and internal inspection to pinpoint every entry point before recommending targeted repairs. We work on both the exterior defects and, where necessary, apply internal waterproofing systems to provide immediate protection.

Canton is a west Cardiff suburb with a mix of Victorian terraces and inter-war housing, known for its independent shops and community feel.

Frequently Asked Questions — Penetrating Damp in Canton

How do I know if I have penetrating damp rather than rising damp?

Penetrating damp usually appears higher on walls, worsens in wet weather, and follows the location of an external defect. Rising damp is typically confined to the lower metre of a wall and shows characteristic salt tide marks. A professional survey will confirm the type.

Can penetrating damp be fixed from the inside only?

In some cases yes — internal waterproofing systems can manage ingress — but wherever possible we recommend fixing the external defect first. This is the most cost-effective and permanent solution.

Will a silicone cream treatment change the look of my walls?

No — properly applied silicone cream treatments are invisible once dry. They allow the wall to breathe while repelling liquid water.
