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 Stevenage

Do you cover all of SG1?

Yes, we cover the SG1 postcode district and the districts around Stevenage.

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

Do you charge extra to travel to Stevenage?

Not normally. Our guide prices include normal travel to Stevenage. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Is condensation in my loft normal?

A little on the coldest nights can be normal, especially with old felt. Dripping, wet insulation or mould are signs to investigate.

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.
