Noisy, failed or leaking fans, PIV, MVHR and commercial extract put right.
Greater London · England
Homes, rentals and business premises in Northolt and HA2, UB5 and UB6.
If you are in Northolt, we can help with anything from a bathroom fan that no longer clears the steam to a full supply and extract system for a shop, office or kitchen. Surveys for new installations are free on the UK mainland, with a written quote afterwards.
For homes in Northolt the usual starting points are extractor fans, PIV and condensation surveys. Whole-home MVHR makes most sense in new builds, big refurbishments and very airtight houses.
For Northolt premises we design, install and maintain supply and extract systems, kitchen canopies and LEV, and we work around opening hours where we can.
