Before we quote in Tottenham
We cover Tottenham and nearby Edmonton, Wood Green and Walthamstow. 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 period homes in Tottenham, the survey looks closely at existing lime mortars and any cement patching that may trap moisture.

Planning and building control in England
Before quoting in Tottenham, 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 Tottenham: 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.
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
Do you cover Tottenham?
Yes — we survey and quote wood fibre external wall insulation in Tottenham (N17) and nearby Edmonton, Wood Green and Walthamstow, with a fixed written price before any work starts.
