Part of every quote

- Fixing design depends on the panel or frame behind the wall
- Most system-built homes have thin, cold walls and no fillable cavity
- Steel-framed BISF houses need care around the upper-storey cladding

Local considerations in Larne
We also cover Carrickfergus and Newtownabbey, close to Larne. Larne is about 19 miles from Belfast. 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.
For concrete houses in Larne, we report any visible spalling or cracking before quoting the insulation, not after.

Northern Ireland: planning and regulations
In Northern Ireland, permitted development is set by the 2015 Order; in Larne, changing a house's external appearance, and any work on flats or listed buildings, may need permission, so we check with the council.
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.
Does EWI fix mortgage problems with PRC houses?
Not on its own. Some precast reinforced concrete (PRC) house types were designated defective, and many lenders want a certified structural repair before they will lend. Insulation and render over the outside is not that repair. Other types, such as Wimpey no-fines, are generally treated differently. If mortgageability matters, speak to your lender or a surveyor before booking any work.

Non-traditional houses in Larne: questions
Can you put EWI on a BISF house?
Yes, with care. The steel frame and upper-storey cladding need a system and fixing method designed for that construction, and the condition of the frame should be understood first.
Can you insulate a Wimpey no-fines house?
Yes. No-fines houses have solid poured-concrete walls with no cavity, so EWI is the usual route. The survey checks the concrete condition first.
What if my neighbour isn't insulating?
We finish the system neatly at the boundary with a closing detail so the neighbouring house isn't affected and can be joined later.
