Condensation in Leeds homes usually has one of two answers: better extract fans, or PIV as well.
Whether the property is in the middle of Leeds 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.

What the work involves
It does not replace extract fans: kitchens and bathrooms still need their own extract to remove steam at source. On survey we check the loft, the landing position and the existing fans, and we tell you if PIV is not the right answer.
PIV with fan upgrades
PIV plus humidity-controlled extract fans in the kitchen and bathroom for the most stubborn condensation.
Loft-mounted PIV
The most common option for houses with a loft. Usually fitted in half a day.
