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 England
In England, a loft insulated across more than half its area should reach a U-value of 0.16 W/m²K. Insulation alone is not usually notified to building control. How the rules work across the UK.
Questions about a loft condensation investigation in Weymouth
Do you cover all of DT4?
Yes, we cover the DT4 postcode district and the districts around Weymouth.
Do you take on jobs outside Weymouth?
Yes. We also work in Dorchester and Bridport and elsewhere in Dorset.
How soon can you visit a home in Weymouth?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Is the investigation fee taken off the work?
The investigation is priced on its own so the advice is not tied to selling work. You decide what to do afterwards.
Can loft insulation cause condensation?
It can expose an existing problem: the loft gets colder, so the same moist air condenses more readily. Ventilation and sealing air leaks put it right.
