What Our Yorkshire Customers Say

5.0from 5 verified reviews

Fantastic job on our Victorian terrace. The spray cork insulation has completely stopped the condensation we had for years. Professional team from start to finish.

Sarah T.

Leeds · March 2025

Had our cracked render repaired and recoated. The house looks brand new. CosyWall were clean, tidy and finished ahead of schedule.

James W.

York · February 2025

We had lime render applied to our listed cottage. They understood exactly what was needed for an old stone building. Highly recommend.

Helen M.

Harrogate · January 2025

Internal wall insulation fitted throughout. Only 10mm thick and the difference in warmth is incredible. Wish we'd done it years ago.

David R.

Sheffield · December 2024

Bay window insulation sorted our coldest room. No mess, no fuss. The team were lovely and explained everything clearly.

Why Breathability Matters for Old Yorkshire Homes

Most Yorkshire homes built before 1919 have solid brick or stone walls with no cavity. Standard insulation, cement render and impermeable coatings trap moisture inside these walls — causing damp, mould and structural damage. Every system CosyWall installs is breathable and vapour-open, allowing moisture to escape while keeping heat in. This is why our logo says: BREATHABLE · THERMAL · PROTECTIVE.
