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.

In England, a loft insulated across more than half its area should reach a U-value of 0.16 W/m²K. Insulation alone is not usually notified to building control. How the rules work across the UK.
Questions about a loft condensation investigation in Erith
How do I pay for work in Erith?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you cover all of DA8?
Yes, we cover the DA8 postcode district and the districts around Erith.
Do you charge extra to travel to Erith?
Not normally. Our guide prices include normal travel to Erith. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
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.
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.
