What we look for in Carrickfergus
We cover Carrickfergus and nearby Holywood, Newtownabbey and Bangor (County Down). It's roughly 10 miles from Carrickfergus 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.
Where one half of a pair in Carrickfergus is insulated and the other isn't, we detail the boundary so the neighbour can join later.

Permissions in Northern Ireland
For Carrickfergus 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.
How do I know if my house is non-traditional?
Clues include concrete panels or posts visible at corners, a smooth concrete or rendered finish on houses of a 1940s–1960s estate, steel sheeting on the upper storey, or a mortgage valuation that mentioned the construction type. Common types include Wimpey no-fines (poured concrete), Airey and Cornish Unit (precast reinforced concrete), Reema, Orlit and BISF (steel frame). We identify the type during the survey.

Non-traditional houses in Carrickfergus: questions
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.
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.
Will EWI make my house mortgageable?
It can make a house more attractive and better insulated, but it does not replace a certified structural repair where a lender requires one. Ask your lender before relying on it.
Do you cover Carrickfergus?
Yes — we survey and quote non-traditional house insulation in Carrickfergus (BT38) and nearby Holywood, Newtownabbey and Bangor (County Down), with a fixed written price before any work starts.
