Social housing ventilation programmes in Gwynedd and Anglesey
Survey-led ventilation upgrades across stock, with per-home records and tenant liaison, across Gwynedd and Anglesey.
- From £625 + VAT per home
- Free survey

Social landlords need to find and fix damp and mould hazards quickly, and ventilation is usually the core of the fix. We survey homes, install continuous extract, PIV or heat recovery as needed, measure the airflow, and report per address so your asset and compliance teams have evidence of what was done.
Gwynedd and Anglesey has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.
