Condensation, mould and landlords, County Down
Social housing ventilation programmes in County Down
Survey-led ventilation upgrades across stock, with per-home records and tenant liaison, across County Down.
- From £600 + VAT per home
- By arrangement

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.
County Down 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.

Questions about social housing ventilation programmes in County Down
Are prices different in County Down?
Our guide prices are adjusted by region. In County Down we use Northern Ireland rates, so social housing ventilation upgrade, per home (survey-led PIV or dMEV programme) is typically £600 to £1,325 + VAT per home.
Do you provide evidence for each home?
Every home gets a report with photographs, products fitted and measured airflow, in a format your teams can upload.
Can ventilation be done alongside insulation retrofit?
Yes. Retrofit under PAS 2035 needs a ventilation assessment, and we can install and test the ventilation measures that come out of it.
Is the survey free in County Down?
Visits here are by arrangement. Because of the ferry or long travel involved, we quote travel separately and in writing before you commit, and we can often combine visits to keep the cost down.
Which rules apply to ventilation in County Down?
In Northern Ireland, ventilation is covered by Technical Booklet K of the Building Regulations (Northern Ireland). Workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993.
