What is a loft condensation investigation?
We inspect the loft in daylight and by torch, measure moisture in the timbers, check the underlay, ventilation, insulation and the routes that let warm air in from the house, and look at the roof from outside. You get written findings with photos and a plain list of what we recommend, which may include work we do not offer. More about a loft condensation investigation.

Building regulations in Northern Ireland
Northern Ireland has its own Building Regulations, with energy guidance in Technical Booklet F1. Upgrading loft insulation may count as a thermal alteration, so check with your council's building control. How the rules work across the UK.
Questions about a loft condensation investigation in Larne
Can a landlord in Larne book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Do you cover all of BT40?
Yes, we cover the BT40 postcode district and the districts around Larne.
Can you visit Larne outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
Is the investigation fee taken off the work?
