Positive input ventilation (PIV) in Stroud
Loft or wall units that gently push filtered air into the home to tackle condensation. Covering Stroud and GL5, GL6 and GL10.
- From £825 inc VAT per home
- Free survey
Condensation in Stroud homes usually has one of two answers: better extract fans, or PIV as well.
Whether the property is in the middle of Stroud 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.

How we approach PIV in Stroud
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.

Questions from Stroud
What is the price of a PIV unit in Stroud?
Guide prices for Stroud use South West rates: positive input ventilation (PIV) loft unit, supplied and fitted is typically £825 to £1,450 inc VAT per home. We confirm a fixed price in writing before any work starts.
Does PIV really stop condensation?
PIV reduces condensation in most homes because it dilutes moist air and keeps it moving, but it works best alongside working extract fans in the kitchen and bathroom. Leaks, rising damp or a cold bridge need fixing separately.
How much does PIV cost to run?
A standard PIV unit uses very little electricity, comparable to a low-energy light bulb on normal speed. A heated unit costs more in cold spells because the heater switches on when loft air is cold.
Is the survey free in Stroud?
