Solutions & treatments

Compare ventilation, moisture control, building repairs and specialist treatments by what they actually solve — and what they do not.

Different moisture sources need different fixes

Ventilation can help condensation. Repointing can help rain penetration through failed joints. Damp-proofing belongs only where rising damp is credibly diagnosed.

01Control moisture in the airVentilation, extraction and dehumidification.
02Stop water getting inRepair roofs, gutters, masonry, seals and leaks.
03Treat building fabric correctlyUse specialist systems only after the cause is established.

What are you considering?

Each guide explains where the solution fits, its limitations, what to check first and when professional installation makes sense.

Start with the cause

Don't start with a treatment name.

Start with the symptom, narrow the cause, then compare solutions that actually fit it.
