Watch for mist inside double glazing, which means the seal has failed and the unit needs replacement. Other issues include rattling panes, water ingress at the sill, and cracked putty within 6 to 18 months. Request a written warranty covering sealed units for 5 to 10 years and workmanship for 12 months.
Modern uPVC windows use rubber gaskets and plastic snap-in beads. Timber frames often use linseed oil putty or a flexible silicone sealant. The right product depends on the frame material. Ask which sealant the glazier will use, since wrong sealant causes leaks within the first wet season.
Glaziers seal glass with silicone, acrylic, or linseed-oil putty depending on the frame. Timber frames usually take putty, uPVC frames use rubber gaskets and snap-in beads. Ask which sealant will be used and its expected lifespan, since cheap silicone can yellow or peel within 12 months on sun-facing faces.
Price depends on glass type, thickness, shape, and whether the pane is toughened or laminated. Access height, frame condition, and whether beading needs replacing also matter. Larger panes over about 1.5 square metres cost more per piece because they are heavier to handle and transport safely.
Cost varies with glass type, thickness, panel size, and access height. Float glass is cheapest, low-e coated or acoustic glass costs more. A small 300 mm by 300 mm pane costs far less than a 1.2 m by 1.5 m double unit. Emergency callouts after hours add 50% to 100% to the labour rate.
A single window pane swap usually takes 30 to 60 minutes once on site. A sealed double glazing unit replacement takes about 45 minutes per unit. A full shower screen install can take 3 to 4 hours. Board-up work after a break-in is often done within 1 hour of arrival.
Replacing a single broken pane takes 30 to 60 minutes once the glass is on the van. Double-glazed unit swaps take 2 to 3 hours including sealant cure time. Full window frame replacement with plastering can run 4 to 6 hours. Order custom or patterned glass takes 5 to 10 working days.
The glazier measures width and height in three places each, top, middle, and bottom, and uses the smallest reading. They also check the frame depth, the rebate size, and the clearance for the glass to expand. For sealed units, a physical visit is needed; phone measurements are not reliable.
Accurate measurement removes a 2 mm to 3 mm clearance on each side for thermal expansion and frame tolerance. The glazier checks the rebate depth, which is usually 12 mm to 20 mm, and notes squareness. Wrong sizes force a second visit and a new sealed unit, so ask who measures and who pays for mistakes.
Any glass within a door, beside a door, or low in a window must be safety glass by law. Look for a permanent marking etched into the corner, such as “toughened” or “laminated”. A glazier should mention this during quoting if your existing pane does not meet current standards.
