Our team is based in Great Barr, Birmingham, about 137 miles from Kesgrave. We plan each Kesgrave 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 Kesgrave, 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 Kesgrave 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.
