Noisy, failed or leaking fans, PIV, MVHR and commercial extract put right.
Greater London · England
Homes, rentals and business premises in Bickley and BR1, BR2 and BR7.
If you are in Bickley, 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 Bickley 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 Bickley premises we design, install and maintain supply and extract systems, kitchen canopies and LEV, and we work around opening hours where we can.
Noisy, failed or leaking fans, PIV, MVHR and commercial extract put right.
