External Wall Insulation in Farnborough
Based in Ash Vale — about 10 minutes from Farnborough
Farnborough has significant solid-wall housing — Reading Road, Pinehurst, parts of Cove and North Camp — that bleeds heat through pre-cavity construction. EWI cuts heating bills materially and eliminates north-facing cold-spot damp.
External Wall Insulation in Farnborough: £130–£190 per m² installed. Fixed written quotes after a free survey.
Farnborough's garrison-adjacent terraces near the town centre — solid-wall construction from before the aerodrome and the aviation industry grew up around it — are the properties where external wall insulation makes the clearest case on our patch: 60–150mm of board and a new render finish, cutting heat loss and renewing the facade together.
Rushmoor Borough Council covers planning in the GU14 postcode area, and the more recent cavity-wall estates built up around the aerodrome through the 20th century generally don't need EWI at all — we say so plainly rather than quoting work that isn't justified. It's one of our closest towns, about 10 minutes from Ash Vale.
