Condensation and mould ventilation fixes in Cheshire

We survey Cheshire homes for condensation with meters, not guesswork, and explain what we find.

Our team is based in Great Barr, Birmingham, and we work throughout Cheshire, from Warrington, Chester, Crewe, Ellesmere Port Town and Widnes. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it

Mould needs that damp surface to grow. Ventilation is usually the biggest part of the cure, but not the only part. Heating patterns, insulation gaps and cold bridges matter too, and some damp is not condensation at all: leaks, penetrating damp and rising damp need different trades.
