Positive input ventilation (PIV) in Burnham

Condensation in Burnham homes usually has one of two answers: better extract fans, or PIV as well.

Whether the property is in the middle of Burnham or one of the villages around it, the process is the same: a look at the building, a written price, then fitting and testing on the agreed day.
