For homes in Shepperton 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 businesses in Shepperton we cover office and shop ventilation, commercial kitchen extraction, duct cleaning to TR19 and planned servicing of air handling units.
Loft or wall units that gently push filtered air into the home to tackle condensation.
Bathroom, kitchen and utility fans sized to the Part F rates, ducted outside and tested.
We find why the house is wet and fix the ventilation, rather than painting over mould.
Tested fans and PIV for rental homes and HMOs, with records for your property file.
