Glass & Mirror in London: what to know

538 glass & mirror firms cover London, across postcode areas including N, EC, W and SW. They are all independent local businesses listed in this directory, so your enquiry goes straight to the firm rather than a national lead broker.

Replacing a single misted (failed) double-glazed unit is far cheaper than a whole new window, and is one of the most common jobs these firms do. Where glass sits in a "critical location" — below 800mm from the floor in a window, or below 1500mm in a door and its side panels — the Building Regulations require safety glazing (toughened or laminated), so a good firm will specify the right glass for each opening.

Glass & Mirror in London — common questions

Can I just replace the misted glass unit rather than the whole window in London?
In most cases, yes. If the frame and hardware are sound, a firm can replace just the failed (misted) sealed unit, which is much cheaper than a new window. If the frame itself is damaged or the hinges are failing, replacing the window may be the better value — a local firm will tell you honestly which applies.
How much does replacing a glass unit cost in London?
A replacement sealed unit is often in the region of £60–£180 supplied and fitted for a standard size, though large, shaped, toughened or specialist (e.g. acoustic or Low-E) units cost more. Get a couple of quotes from London firms with your exact sizes to compare.
