If your Lowestoft flat has no loft, a wall-mounted PIV unit does the same job through an outside wall.
Whether the property is in the middle of Lowestoft 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.

PIV for Lowestoft homes
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.

Rules that apply in England

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.
