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 Sutton

What do I need to do before you arrive in Sutton?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Do you charge extra to travel to Sutton?

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

How do I pay for work in Sutton?

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

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 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.
