What we look for in Basingstoke
We also cover Fleet and Thatcham, close to Basingstoke. It's roughly 28 miles from Basingstoke to Southampton, the largest town in Hampshire. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Exposure to wind-driven rain varies across Hampshire: 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 Basingstoke, the survey looks closely at existing lime mortars and any cement patching that may trap moisture.

England: planning and regulations
Before quoting in Basingstoke, 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.
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 Basingstoke: 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.
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 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.
Do you cover Basingstoke?
Yes — we survey and quote wood fibre external wall insulation in Basingstoke (RG21) and nearby Fleet, Thatcham and Yateley, with a fixed written price before any work starts.
