Homes, rentals and business premises in Rastrick and HD2, HD6 and HX5.
We cover Rastrick (HD2, HD6 and HX5) as part of our work across West Yorkshire. We can help homeowners, landlords and businesses with new systems, testing, cleaning and repairs.
For homes in Rastrick 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 Rastrick 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.
