In Portstewart, as everywhere, if the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos and we'll tell you what we think has failed.

What you might be seeing

  • Glare on screens or worktops
  • Furniture or flooring fading under the lantern
  • Clear, uncoated glass in an older lantern

Why it happens

Clear or standard Low-E glass

Standard units let a lot of solar heat through; solar control coatings reflect more of it.

Orientation

South- and west-facing lanterns gain the most heat in the afternoon.

Solar control and self-cleaning glass upgrades in Portstewart: questions

Do you need to visit to price solar control and self-cleaning glass upgrades?

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 Portstewart?

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.
