Condensation and mould ventilation fixes
We find why the house is wet and fix the ventilation, rather than painting over mould.
Mid Glamorgan · Wales
Homes, rentals and business premises in Maesteg and CF32, CF34 and SA13.
Our team is based in Great Barr, Birmingham, about 99 miles from Maesteg. We plan each Maesteg job around the survey, so you get a fixed written price and an agreed date rather than an estimate on the day.
In many Maesteg 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.
For businesses in Maesteg we cover office and shop ventilation, commercial kitchen extraction, duct cleaning to TR19 and planned servicing of air handling units.
