External Wall Insulation in
Clifton

External wall insulation is rarely appropriate in Clifton — solid-walled Georgian construction needs to breathe, and EWI traps moisture against the stonework. The few exceptions are post-1960s infill properties that were built with cavity walls. For the period stock we recommend internal dry-lining with breathable insulation instead.

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.

Clifton is Georgian Bristol, and it behaves like it. The terraces around Royal York Crescent, Cornwallis Crescent and the Polygon are stucco over rubble stone or soft brick — solid-wall construction that has to breathe. A modern cement-rich or non-breathable system traps moisture in the masonry and pushes damp inwards, which is why lime-compatible work matters here in a way it does not on a 1930s semi in Fishponds. A large share of the stock is listed or sits inside the Clifton and Hotwells conservation area, so Listed Building Consent or conservation area approval is routine rather than exceptional. There is also a substantial Victorian and Edwardian villa stock on the streets running back from the Downs, and a growing number of flat conversions where work is often limited to a single dwelling within a larger building. Access is the other constant: narrow streets, residents' parking and very little room for scaffold on the crescents.
