Ventilation repairs and fault finding
Noisy, failed or leaking fans, PIV, MVHR and commercial extract put right.
Greater London · England
Homes, rentals and business premises in Chalk Farm and NW1, NW3 and NW5.
Damp walls, steamed-up windows, a noisy fan or a kitchen canopy that drips grease: each of these has a cause we can measure and a fix we can price before any work starts in Chalk Farm.
In many Chalk Farm 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 Chalk Farm premises we design, install and maintain supply and extract systems, kitchen canopies and LEV, and we work around opening hours where we can.
Noisy, failed or leaking fans, PIV, MVHR and commercial extract put right.
Whole-home heat recovery ventilation, designed room by room and airflow-tested at handover.
Annual service, filters, heat exchanger clean and a measured airflow check for existing MVHR.
Loft or wall units that gently push filtered air into the home to tackle condensation.
