How we approach skylight repairs & leak fixes in Falmouth
Our skylight repairs & leak fixes service in Falmouth covers leak tracing, resealing, actuator repairs and glass replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Skylight repairs & leak fixes suit leaks, condensation, misted units and failed actuators.
Falmouth sits about 12 km from Truro and 14 km from Redruth, and we cover the whole TR11 postcode district and the roads in between.

Do you need permission in Falmouth?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.
