Loft insulation in Falmouth

Loft insulation lays mineral wool between and over the ceiling joists to the recommended depth, cutting heat loss through the roof. In Falmouth we follow the England rules on building notices and self-certification, and confirm the route on your quote.

Loft insulation for Falmouth properties

If your property is in Falmouth or the TR11 district or nearby Truro, Redruth and Camborne, it is within our Cornwall coverage. It is about 7 miles south of Truro.

We check ventilation as carefully as insulation in Falmouth homes, because both matter for keeping a house dry. In Falmouth homes this is often done on the same visit as a cavity fill, which saves a second trip.

For regulations, if cavity wall insulation follows in Falmouth, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
