Homes and walls in Farnworth
As well as Farnworth itself, we quote in Walkden, Bolton and Radcliffe. It's roughly 8 miles from Farnworth to Manchester, the largest town in Greater Manchester. The North West has one of the largest stocks of pre-1919 solid-wall terraces in England, alongside Pennine stone houses and post-war estates.
Exposure to wind-driven rain varies across Greater Manchester: 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 period homes in Farnworth, the survey looks closely at existing lime mortars and any cement patching that may trap moisture.

Planning and building control in England
For a house in Farnworth, 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.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
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 Farnworth: questions
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.
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 Farnworth?
Yes — we survey and quote wood fibre external wall insulation in Farnworth (BL4) and nearby Walkden, Bolton and Radcliffe, with a fixed written price before any work starts.
