Why this matters
Cooking, breathing, drying clothes, long showers — typical UK family makes 10–15 litres of vapour a day.
Modern airtight homes trap that moisture. Trickle vents closed, fans broken, no whole-house circulation.
Single glazing, uninsulated external walls, cold corners — the moisture condenses out wherever the surface is coldest.
Rooms left unheated for cost. Cold air holds less moisture, so condensation forms — but heating without ventilation makes it worse, not better.
PIV (Positive Input Ventilation) tackles causes 1 and 2 — the cause of 90% of UK home condensation. Read the full PIV guide →
Common questions
Yes. The condensation check is free. The follow-up survey (if you book one) is also free, no obligation. We make money on the work itself, not on hooks or hidden fees.
No. One email with your report. One follow-up to book a survey. After that, only if you reply or ask. No newsletter, no chase sequence.
It gives you a directional severity rating and tells you whether PIV is likely the right fix. The actual diagnosis needs eyes on it — that's what the free survey is for. We won't recommend PIV unless we're sure it's condensation.
If your symptoms point to damp rather than condensation, take our damp self-check instead. Or just book a survey — we diagnose first, recommend second.
