Our team is based in Great Barr, Birmingham, about 139 miles from Portslade. We plan each Portslade job around the survey, so you get a fixed written price and an agreed date rather than an estimate on the day.
If you are extending or converting in Portslade, ventilation is part of Building Regulations sign-off. We can fit the fans or MVHR and provide the airflow test results your inspector will ask for.
For businesses in Portslade 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.
