Homes and walls in Holywood
We also cover Newtownabbey and Belfast, close to Holywood. It's roughly 6 miles from Holywood to Bangor (County Down), the largest town in County Down. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Exposure to wind-driven rain varies across County Down: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
Freeholders and managing agents in Holywood get a written specification and pricing they can share with owners.

Northern Ireland: planning and regulations
For Holywood homes, the council's planning office has the final say on external changes; conservation areas, flats and listed buildings need an application or consent.
Council building control in Northern Ireland checks insulation work of this kind; the quote says how the application is handled.
On taller buildings in Northern Ireland we specify non-combustible mineral wool systems and confirm the classification with building control, in line with Technical Booklet E.
For flats, the lease or management agreement sets how owners agree to the work and share its cost.
How disruptive is it for residents?
Most work happens from scaffolding outside. Residents may need to allow brief access to extend window cills, vents or flues from the inside. We provide a notice for residents covering dates, scaffold, and how to raise concerns.

Flats and blocks in Holywood: questions
Do flats need planning permission for EWI?
Yes. Permitted development rights for external alterations apply to houses, not flats or maisonettes, so an application is needed.
Can one flat have external wall insulation on its own?
Rarely. The outside walls are usually owned by the freeholder, the result would look patchy, and planning is unlikely. Whole-building schemes are the norm.
Do you cover Holywood?
Yes — we survey and quote EWI for flats and blocks in Holywood (BT18) and nearby Newtownabbey, Belfast and Castlereagh, with a fixed written price before any work starts.
