For a typical Inverness semi or terrace, a loft PIV unit is often the quickest way to dry the house out.
Whether the property is in the middle of Inverness 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 Inverness 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.
Wall-mounted PIV for flats
Draws air from outside through an outside wall. Suits flats and homes with no loft space.
PIV with fan upgrades
PIV plus humidity-controlled extract fans in the kitchen and bathroom for the most stubborn condensation.
