Treatments
Penetrating damp repairs
Clearly sequenced penetrating damp repairs after rainwater entry routes have been investigated.
Why diagnosis matters
Treat the cause, then repair the damage
A durable repair starts at the entry point, not the damaged paint. We define which defect should be corrected, what specialist referral is needed and when internal reinstatement can begin.

Common questions
About penetrating damp repairs
Why repair outside first?+
Internal decoration cannot remain sound while water continues to enter. Source correction also allows the drying response to be monitored.
Can several defects contribute?+
Yes. Older properties often have more than one maintenance issue, so the scope may prioritise work in stages.
Do you guarantee every leak stops?+
Guarantee wording is tied to the specified repair, access and exclusions. We do not promise a universal cure for unrelated defects.
