Domestic ventilation and PIV maintenance
Keeping ventilation and PIV units working properly, so homes stay drier and healthier.

Ventilation only helps if it is maintained. Blocked filters, clogged extract fans and neglected PIV units quietly stop moving air, and condensation and damp follow.
We service domestic ventilation systems, change filters, clean extract fans and ductwork, and check airflow so the system does what it was installed to do. Where a unit is faulty or wrongly specified, we will tell you plainly rather than keep servicing it.
