Misted and blown glass units Northern Ireland

Replacing only the sealed unit keeps your Northern Ireland frame in place, so the rest of your frontage stays exactly as it is. Rough sizes and a photo of the spacer bar may be all we need to price sealed units for your Northern Ireland shop.

What do we fix in Northern Ireland?

Water in the cavityVisible water means the seal failed some time ago. We check how it got in before fitting the new unit.

Blocked frame drainageWater sitting in the glazing pocket attacks the edge seal. Clearing the drainage path helps the new unit last.

Better glass in the same frameA replacement unit can often include solar control or low-emissivity glass at the same overall thickness.

How much does it cost in Northern Ireland?

As a guide, allow £165 to £695 ex VAT per sealed unit. Landlords with several misted units in Northern Ireland or across the area can have them measured together, rather than one at a time. We set out every cost in writing before work starts.

Which towns do you cover?

Common questions

Do you cover all of Northern Ireland?

Yes. ShopFronts UK works across Northern Ireland, including Antrim, Armagh, Ballymena, Bangor, County Down. Remote areas are by arrangement.

How long does a replacement sealed unit take?

Sealed units are made to measure, so the wait is typically counted in weeks rather than days, depending on size and glass type. You get the expected lead time alongside your price, and the old unit stays in place until the new one is ready to fit.

Can misted double glazing be repaired?

No lasting repair exists once the edge seal has failed, so the unit is replaced. Drilling and drying services may clear the view for a while, but they do not restore the seal or the gas fill. Changing only the unit keeps your frame.

Is a misted unit still insulating?

A misted unit usually insulates less well, because gas has escaped and damp air has replaced it. The glass is still a barrier, so it is rarely an emergency. It does look poor, and moisture can leave permanent marks on the inner faces.
