External Wall Insulation in
Hanham

Hanham's 1930s semis are ideal candidates for EWI — they're cavity-walled with thin blocks and run cold on winter mornings. We install 90-100mm graphite EPS with silicone top coat, typically achieving a U-value below 0.30 W/m²K.

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.

Hanham is where KD Plastering & Rendering Services is based — our office on Roman Way sits a five-minute walk from the Memorial Park. We render more properties in Hanham than anywhere else, and we know the housing stock intimately. The 1930s semi-detached homes along Court Road, Tabernacle Road and the Avon Ring Road form the backbone of the area — typically 3-bed, 900-1,100 sq ft, with original sand-and-cement or pebbledash render that's now 60-80 years old and reaching end-of-life. The post-war detached homes on the Park Farm and Blue Mountain estates (built 1955-1975) are generally larger — 1,200-1,800 sq ft — and many have original 1970s pebbledash that's failing. The newer homes on the riverside developments and the Blue Mountain extension are 1990s-2000s executive detached, typically already rendered but with acrylic systems that are starting to fail. Whatever your Hanham property, we can render it.
