What we look for in Chippenham
We also cover Trowbridge and Bath, close to Chippenham. It's roughly 16 miles from Chippenham to Swindon, the largest town in Wiltshire. 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 Wiltshire: 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 Chippenham, we look at a wood fibre and lime build-up first.

England: planning and regulations
Before quoting in Chippenham, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
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.
What finish goes over wood fibre?
A lime-based or mineral render designed for the system, applied over a reinforcing base coat. Lime finishes give the softer, slightly irregular texture that suits cottages and older terraces.

Wood fibre EWI in Chippenham: questions
Is wood fibre worth the extra cost?
On older solid walls the main benefit is moisture safety rather than raw U-value. If the wall needs to breathe, the cheaper option can cost more later.
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.
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.
Do you cover Chippenham?
Yes — we survey and quote wood fibre external wall insulation in Chippenham (SN15) and nearby Trowbridge, Bath and Chipping Sodbury, with a fixed written price before any work starts.
