About Carrickfergus and the BT38 area

Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

From Belfast to Carrickfergus is roughly 10 miles — all part of the County Antrim area we cover.

Do you need permission in Northern Ireland?

Most lantern repairs in Northern Ireland need no approval at all. Where a job turns into a replacement, the Building Regulations (Northern Ireland) 2012 apply and we confirm how the work will be signed off before we start. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.

Roof lantern replacement in Carrickfergus: questions

Do you need to visit to price roof lantern replacement?

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Can you repair a lantern someone else installed in Carrickfergus?

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

Can the new lantern use the existing opening?

Usually, if the kerb is sound and the size suits a standard or made-to-measure lantern.

Will you tell me if repair is enough?

Yes. We'd rather do a repair that works than sell a lantern you don't need.
