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 Dolgellau
How do I pay for work in Dolgellau?
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 Dolgellau?
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 Dolgellau?
Not normally. Our guide prices include normal travel to Dolgellau. 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.
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.
