Damp and moisture issues need proper diagnosis — not quick fixes
Most damp problems are misdiagnosed.
Contractors often oversell treatments, inject chemicals unnecessarily, or recommend generic “damp proofing” that fails because the root cause wasn’t identified.
We provide independent, evidence-based damp & timber investigations across London.
No injections. No sales upsells. No biased advice.
Just a clear, accurate explanation of:
- what the issue actually is
- what caused it
- what’s needed to fix it
- how much repairs should realistically cost
