Misted and blown glass units Greater London

Replacing only the sealed unit keeps your Greater London 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 Greater London shop.

What do we fix in Greater London?

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

Common questions

Do you cover all of Greater London?

Yes. ShopFronts UK works across Greater London, including Acton, Barking, Brixton, Bromley.

Could a misted unit still be under warranty?

It could be, if the unit is recent. Manufacturers' warranties cover glass units, so look for a maker's name or date on the spacer bar and check your paperwork. Our 10-year guarantee covers workmanship only, and applies to work we have carried out.

Will a new unit match the others in my shopfront?

Usually, if we match the glass type, coatings and spacer colour. A new unit can look slightly different beside old panes, particularly if those have a tint. We check this before ordering, and can replace adjoining units together if you prefer.

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.
