External Wall Insulation in
Downend

Downend's 1930s semis are solid 9-inch brick — too cold for modern heating bills. EWI with 90mm graphite EPS brings the U-value down dramatically and eliminates the cold-bridge condensation that plagues solid-wall properties.

If your Bristol home was built before 1990, chances are it has no cavity wall insulation and minimal loft insulation. The result: heat loss through the walls (up to 35% of your total heat loss), cold spots around window reveals, condensation on inside walls, and high energy bills. External Wall Insulation fixes all of this in one go. We fix 80-150mm of high-performance insulation board to the outside of your property, then apply a reinforced base coat and a silicone or monocouche render finish. The result: a 25-35% reduction in heating bills, elimination of condensation, and a fresh modern exterior. EWI typically pays for itself in 8-12 years through energy savings. We install Weber, K Rend and Johnstone's EWI systems.

Downend is one of the more upmarket South Gloucestershire suburbs — leafy streets, larger detached properties, and the consistently high-performing Downend School feeding into it. The housing stock is dominated by post-war detached homes on the estates (built 1955-1975) which were originally finished in 1970s pebbledash that's now failing. These homes are typically 1,200-1,800 sq ft and represent excellent candidates for a full silicone re-render or EWI upgrade. The newer executive detached homes (1990s-2000s) are also increasingly needing re-rendering as their original acrylic systems age out.
