Before we quote in Bodmin
Surveys in Bodmin also cover the surrounding PL31 district and towns such as St Austell and Newquay. It's roughly 28 miles from Bodmin to Redruth, the largest town in Cornwall. 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.
Parts of Cornwall fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
If your home in Bodmin is in a conservation area, we check the council's position on render before suggesting wood fibre EWI.

Permissions in England
Before quoting in Bodmin, 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.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
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 Bodmin: questions
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
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 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.
Do you cover Bodmin?
Yes — we survey and quote wood fibre external wall insulation in Bodmin (PL31) and nearby St Austell, Newquay and Truro, with a fixed written price before any work starts.
