Loft or wall units that gently push filtered air into the home to tackle condensation.
Surrey · England
Homes, rentals and business premises in Weybridge and KT13, KT15 and TW17.
Our team is based in Great Barr, Birmingham, about 102 miles from Weybridge. We plan each Weybridge job around the survey, so you get a fixed written price and an agreed date rather than an estimate on the day.
In many Weybridge homes the first step is better extraction in the kitchen and bathroom. If the windows still stream after that, a PIV unit or continuous fans usually finish the job.
Commercial work in Weybridge is priced from a site visit or your drawings. Kitchen extract cleaning, LEV testing and servicing visits are priced per system.
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.
