Before we quote in Havant
Surveys in Havant also cover the surrounding PO9 district and towns such as Waterlooville and Portsmouth. Havant is about 19 miles from Southampton. 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.
If your home in Havant is in a conservation area, we check the council's position on render before suggesting wood fibre EWI.

England: planning and regulations
For a house in Havant, 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.
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 about listed buildings and conservation areas?
EWI on a listed building needs listed building consent and is often refused where the outside appearance matters. In conservation areas, rendering or cladding a house normally needs planning permission. Wood fibre and lime are more likely to be acceptable than foam and acrylic, but the council decides. We check before quoting.

Wood fibre EWI in Havant: questions
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 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.
Do you cover Havant?
Yes — we survey and quote wood fibre external wall insulation in Havant (PO9) and nearby Waterlooville, Portsmouth and Gosport, with a fixed written price before any work starts.
