Hanworth: walls, weather and approvals
Surveys in Hanworth also cover the surrounding TW13 district and towns such as Feltham and Sunbury-on-Thames. London's housing includes a large stock of Victorian and Edwardian solid-wall terraces, inter-war semis and post-war blocks, and conservation areas cover many streets — so planning is often the first question for external work.
Much of Greater London sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
For older stone and early brick properties in Hanworth, we look at a wood fibre and lime build-up first.

Planning and building control in England
Planning in Hanworth follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
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.
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 Hanworth: 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.
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 Hanworth?
Yes — we survey and quote wood fibre external wall insulation in Hanworth (TW13) and nearby Feltham, Sunbury-on-Thames and Hounslow, with a fixed written price before any work starts.
