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.

Questions about a loft condensation investigation in Hounslow

How do I pay for work in Hounslow?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

Can a landlord in Hounslow 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 TW3?

Yes, we cover the TW3 postcode district and the districts around Hounslow.

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.

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.
