Local considerations in Larne
We cover Larne and nearby Carrickfergus, Newtownabbey and Bangor (County Down). It's roughly 19 miles from Larne to Belfast, the largest town in County Antrim. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Antrim fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
If your home in Larne is in a conservation area, we check the council's position on render before suggesting wood fibre EWI.

Planning and building control in Northern Ireland
Before quoting in Larne, we check whether the property is listed or in a conservation area, which changes what needs planning permission in Northern Ireland.
Council building control in Northern Ireland checks insulation work of this kind; the quote says how the application is handled.
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 Larne: questions
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.
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.

Yes — we survey and quote wood fibre external wall insulation in Larne (BT40) and nearby Carrickfergus, Newtownabbey and Bangor (County Down), with a fixed written price before any work starts.
