Positive input ventilation (PIV)
Loft or wall units that gently push filtered air into the home to tackle condensation.
Greater London · England
Homes, rentals and business premises in Croydon and CR0, CR2, CR5 and CR7.
We cover Croydon (CR0, CR2, CR5 and CR7) as part of our work across Greater London. We can help homeowners, landlords and businesses with new systems, testing, cleaning and repairs.
For homes in Croydon 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 Croydon 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.
