Homes, rentals and business premises in Downham Market and PE33 and PE38.
Our team is based in Great Barr, Birmingham, about 96 miles from Downham Market. We plan each Downham Market 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 Downham Market, 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 Downham Market premises we design, install and maintain supply and extract systems, kitchen canopies and LEV, and we work around opening hours where we can.
Supply and extract with heat recovery for offices, shops, clinics and fit-outs.

Noisy, failed or leaking fans, PIV, MVHR and commercial extract put right.
