Questions from Lisburn
What is the price of a ventilation repair in Lisburn?
Guide prices for Lisburn use Northern Ireland rates: home repair or fault-finding visit, first hour (parts extra) is typically £85 to £150 inc VAT per visit. We confirm a fixed price in writing before any work starts.
Why is my extractor fan humming but not spinning?
A humming fan that does not spin often has a failed capacitor, seized bearing or obstruction. It should be switched off until repaired.
Why is water dripping from my ventilation?
Drips usually come from condensation in an uninsulated duct, a blocked condensate drain or a duct sloping the wrong way.
Is the survey free in Lisburn?
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.
