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 St Albans

Can you visit St Albans 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.

How do I pay for work in St Albans?

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

Do you take on jobs outside St Albans?

Yes. We also work in Harpenden and Hatfield and elsewhere in Hertfordshire.

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.
