A
Glass replacement
Frames kept · glass renewedIn nine cases out of ten a broken, misted or draughty window needs new glass, not a new window. We reglaze uPVC, aluminium and timber frames at a fraction of the cost of replacement, with no mess and no redecorating.
Misted & failed double glazed units
Condensation between panes means the sealed unit has failed. We replace the unit only. The frame stays.
Typical specUnits made to measure · 7-10 days · fitted in under an hour each
Double glazing repairs
Failed seals, cracked panes, packers and re-toe-and-heeling of dropped sashes, all part of our wider window & door repair service.

Specialist glass
Specified to the job, not the shelfThe right glass depends on what the pane has to do: resist impact, hold together when broken, block noise, hold back fire or keep heat in. Every specialist type below can be supplied as single panes or built into sealed double glazed units.
Toughened safety glass B1
Heat-treated to roughly five times the strength of float; shatters into blunt granules. The default for doors, low-level glazing and table tops.
4mm6mm10mm12mm
Laminated security glass B2
Two panes bonded over a PVB interlayer. It cracks but stays in the frame, so it resists burglars and protects shopfronts and rooflights.
6.4mm6.8mm8.8mm11.5mm
Acoustic / soundproof glass B3
Asymmetric panes with an acoustic interlayer cut traffic and flight-path noise. Pairs well with secondary glazing on the worst roads.
6.4mm6.8mm10.8mm
Fire-rated glass B4
Holds integrity for 30 or 60 minutes in doors, screens and vision panels. See our fire door service for certified installation.
7mm E3011mm E6015mm EI30
Low-E energy efficient glass B5
An invisible metallic coating reflects room heat back inside. Standard in every sealed unit we make, and it cuts heat loss through the glass by more than half.
4mm6mmin 28mm units
Solar control glass B6
Tinted or coated to reject summer solar gain: the fix for overheating south-facing rooms, rooflights and glazed extensions.

Questions
Glass replacement, answered
How quickly can you replace broken glass in London?
Stock float, toughened and laminated glass can usually be cut and fitted the same day. Made-to-order sealed double glazed units typically take 7-10 working days; we can board up or fit temporary glazing in the meantime, 24/7. See emergency glazing.
Can you replace just the glass and keep my existing frames?
Yes. In most cases we replace only the glass or the sealed unit, whether the frame is uPVC, aluminium or timber. It is significantly cheaper than replacing the whole window and there is no redecorating afterwards. If the frame itself is failing, our window & door repair team will tell you honestly.
What thickness of glass do I need?
It depends on the pane size and use: 4mm float suits small windows, 6mm for larger panes and shelving, 6.4mm laminated for safety-critical areas, and 10-12mm toughened for frameless showers, balustrades and heavy-use doors. We confirm the correct specification when we measure.
Is toughened or laminated glass required by law?
Building Regulations (Approved Document K) require safety glass in critical locations: glazed doors, side panels within 300mm of a door, and glazing below 800mm from floor level. We fit toughened or laminated glass marked to BS EN 12150 / BS EN 14449 in these zones as standard.
Do you charge for quotes on glass replacement?
No. Send a photo and rough sizes on WhatsApp to 07399 253464 for an instant estimate, or book a free measured survey. The fixed price we agree before work starts is the price you pay.
Do you supply and fit mirrors and splashbacks?
Yes: mirrors and mirror walls, coloured glass splashbacks, shower screens, glass shelving and even cat flaps cut into glass. Everything is templated, cut to size and installed by our own glaziers.
