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 Portsmouth

How do I pay for work in Portsmouth?

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

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

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.

Can you visit Portsmouth 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.

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.
