Frequently asked questions

Why has the glass in my Belfast & County Antrim window gone cloudy?

Cloudiness between the panes of a Belfast & County Antrim unit means the seal has failed; replacing just the sealed unit clears it without changing the frame.

Can you replace units in any frame?

Yes - we replace sealed units in aluminium, timber, steel and uPVC frames where the frame itself is sound.

Is replacing the unit cheaper than a new window?

Much cheaper - you keep the existing frame and only renew the glass.

Which towns in Belfast & County Antrim do you cover for sealed unit replacement?

We provide sealed unit replacement across the whole of Belfast & County Antrim, including Belfast, Lisburn, Newtownabbey, Carrickfergus, Antrim, Ballymena and the wider County Antrim.
