Local considerations in Limavady
We cover Limavady and nearby Coleraine, Derry~Londonderry and Magherafelt. Limavady is about 15 miles from Derry~Londonderry. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Londonderry 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.
For period homes in Limavady, the survey looks closely at existing lime mortars and any cement patching that may trap moisture.

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 Limavady: 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.
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 Limavady?
Yes — we survey and quote wood fibre external wall insulation in Limavady (BT49) and nearby Coleraine, Derry~Londonderry and Magherafelt, with a fixed written price before any work starts.
