We carry out solar control and self-cleaning glass upgrades in Larne and across the BT40 area. If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame.

What you might be seeing
- The room is noticeably hotter than the rest of the house in summer
- Glare on screens or worktops
- Furniture or flooring fading under the lantern
What usually causes it?
Orientation
South- and west-facing lanterns gain the most heat in the afternoon.
No ventilation
A lantern without opening vents traps warm air at ceiling level.
Roof lanterns in Larne
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
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.
We cover Larne as part of County Antrim, about 18 miles from Belfast.
If you're just outside Larne, we also cover Carrickfergus (9 miles), Newtownabbey (14 miles), Bangor, Down (14 miles).
How much should it cost?
Most solar control and self-cleaning glass upgrades jobs come in between £345 and £895 ex VAT (£414–£1,074 including VAT), per glass unit. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in Northern Ireland?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Northern Ireland. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations (Northern Ireland) 2012; we confirm in writing which route applies before any replacement. 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.

Solar control and self-cleaning glass upgrades in Larne: questions
Do you cover Larne?
Yes. We cover Larne, including the BT40 postcode area, as part of County Antrim. Send photos by WhatsApp or the form for a free guide price, and we'll confirm the fixed price in writing before any work starts.
Can you repair a lantern someone else installed in Larne?
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 you add a film instead?
Films are cheaper but can affect the unit's warranty and may not suit sloped double glazing. We'd rather replace the unit properly.
Does self-cleaning glass mean no cleaning?
It reduces cleaning on the outer face but still needs rain and occasional rinsing, and the inside still needs cleaning.
