Magherafelt: walls, weather and approvals
We cover Magherafelt and nearby Cookstown, Ballymena and Antrim. Magherafelt sits around 33 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 Magherafelt, the survey looks closely at existing lime mortars and any cement patching that may trap moisture.

Planning and building control in Northern Ireland
For Magherafelt homes, the council's planning office has the final say on external changes; conservation areas, flats and listed buildings need an application or consent.
External wall insulation is building work under the Building Regulations (Northern Ireland) 2012, so council building control is involved, with Technical Booklet F1 covering dwellings.
Why do older walls need breathable insulation?
Stone and early brick walls were built with lime mortars and renders that let moisture in and out. Sealing them with impermeable materials can trap water in the wall, leading to damp and frost damage. Wood fibre keeps the build-up open to vapour, and its ability to absorb and release moisture helps the wall stay in balance.

Wood fibre EWI in Magherafelt: questions
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.
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 Magherafelt?
Yes — we survey and quote wood fibre external wall insulation in Magherafelt (BT45) and nearby Cookstown, Ballymena and Antrim, with a fixed written price before any work starts.
