Homes and walls in Gloucester
As well as Gloucester itself, we quote in Cheltenham, Stroud and Ross-on-Wye. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Gloucestershire: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For older stone and early brick properties in Gloucester, we look at a wood fibre and lime build-up first.

England: planning and regulations
For a house in Gloucester, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
Why do older walls need breathable insulation?
Stone and early brick walls were built with lime mortars and renders that let moisture in and out. Sealing them with impermeable materials can trap water in the wall, leading to damp and frost damage. Wood fibre keeps the build-up open to vapour, and its ability to absorb and release moisture helps the wall stay in balance.

Wood fibre EWI in Gloucester: questions
Can wood fibre go on a stone wall?
Yes, after levelling. Rubble stone is often uneven, so a levelling coat or adapted fixing method is used first.
Is wood fibre insulation fireproof?
No — it's a timber product. It chars rather than flaming readily, but it is combustible, so it's used on low-rise buildings within a tested system and never where non-combustible materials are required.
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
Do you cover Gloucester?
Yes — we survey and quote wood fibre external wall insulation in Gloucester (GL1) and nearby Cheltenham, Stroud and Ross-on-Wye, with a fixed written price before any work starts.
