What the work involves

A typical family puts several litres of water into the air every day. If extract fans are weak, ducted into the loft or switched off, and windows stay shut in winter, that moisture settles on the coldest surfaces: window reveals, external corners, behind wardrobes and on bathroom ceilings. Mould needs that damp surface to grow.

Survey and findings

Humidity and surface readings, existing fans flow-tested, and a written list of causes and fixes.

Fan upgrades

Weak or loft-vented fans replaced and ducted outside, with humidity control.

Whole-home ventilation

PIV, continuous extract or MVHR where moisture is spread through the house.

Questions about condensation and mould ventilation fixes in County Tyrone

Are prices different in County Tyrone?

Our guide prices are adjusted by region. In County Tyrone we use Northern Ireland rates, so new ducted fan to outside through the loft or ceiling (insulated duct, roof or soffit outlet) is typically £410 to £675 inc VAT per fan.

Will a dehumidifier fix condensation?

A dehumidifier helps in one room but treats the symptom. Fixing the extract in the wet rooms, and adding whole-home ventilation where needed, removes moisture before it spreads.

Is black mould dangerous?

Damp and mould can affect health, particularly for people with asthma, allergies, weak immune systems, children and older people, according to NHS and government guidance. It should be dealt with rather than lived with.

Is the survey free in County Tyrone?

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 Tyrone?

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.
