Loft or wall units that gently push filtered air into the home to tackle condensation. Covering Slough and SL1, SL2 and SL3.
- From £875 inc VAT per home
- Free survey
Condensation in Slough homes usually has one of two answers: better extract fans, or PIV as well.
Whether the property is in the middle of Slough 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
Loft air is usually a little warmer and drier than outside air, and the unit filters it before it comes down into the house. Many units have a temperature sensor that reduces the flow or switches to a heater module on cold days, so the incoming air does not feel like a draught.
Heated PIV
A heater module tempers the incoming air in cold weather. Useful in homes where people feel draughts.
Wall-mounted PIV for flats
Draws air from outside through an outside wall. Suits flats and homes with no loft space.

- The house feels stuffy and damp rather than cold
- Washing dried indoors makes everything worse
- You have no loft but still need whole-flat ventilation (wall unit)
