Lewisham: broken window glass repair
Older sealed units often have plain float glass on both sides. A replacement unit can use a low-emissivity coated pane and a gas-filled cavity, which reduces heat loss through the glass without changing the frame. The coating faces into the cavity and is not noticeable in normal use.
Swapping glass in an existing frame is normally treated as a repair rather than notifiable building work in England. Replacing the whole frame and opening parts is different and usually needs to be notified, either through building control or a competent person scheme such as FENSA or Certass.
Sealed units are made to measure, so the glazier records the width, height and overall thickness of the existing unit rather than the frame opening. The new unit has to match that thickness to sit correctly in the rebate and take the original beads, otherwise the seal and security of the pane suffer.
Units with Georgian bars or leaded designs can be remade to match the originals. The glazier notes the bar width, colour and layout, or the lead pattern, so the new unit lines up with neighbouring windows. Bars fitted inside the cavity are protected from dirt and need no separate cleaning.
Included as standard
- Survey and measurement of the existing glass or unit
- Made-to-measure glass or sealed unit to suit the frame
- Removal of the old pane and cleaning of the rebate

- Coast
- Lewisham is well inland, around 27 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Lewisham the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. On south and west elevations, a solar control or low-E coating changes how much heat and glare new glass lets in. North-facing rooms usually benefit more from glass that keeps heat in while admitting as much daylight as possible.
- Access and setting
- In towns and cities, replacing glass in flats or above shops often means planning parking, stair access and lifting large units safely. Laminated glass suits ground-floor windows, acoustic glass helps on busy roads, and conservation areas may need matching patterns.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Approved Document L sets the minimum energy performance for replacement windows and doors in existing homes in England: a U-value of 1.4 W/m²K, or Window Energy Rating band B for windows; doors can instead meet a Door Set Energy Rating (band B, or band C for doors more than 60% glazed); rooflights need 2.2 W/m²K.
Specification choices
Low-E energy unit
A coated pane and gas-filled cavity that reduce heat loss through the glass compared with older plain float glass units.
Acoustic laminated glass
Laminated glass with a sound-dampening interlayer, often combined with unequal pane thicknesses to reduce traffic and street noise.
Triple glazed unit
Three panes and two cavities for extra insulation, where the frame's rebate is deep enough to take the thicker unit.
Replacement Glass in Lewisham: questions
How long does it take to get replacement glass fitted?
There are usually two stages: a survey to measure, then a fitting visit once the glass has been made. Toughened glass and sealed units are manufactured to order, so they cannot be cut from stock while the glazier waits. Fitting itself usually takes a short time per window. Your quote will set out when the glass is expected, and we will tell you honestly when a glazier can attend.
What guarantee comes with replacement glass?
Manufacturer guarantees apply to new sealed units and glass, and the terms are confirmed in writing. Guarantee terms for the fitting are set out in writing with your quote. Keep the paperwork with your property records, as it identifies the unit and its specification if anything needs to be checked or claimed later.
Can I replace a sealed unit myself?
Single panes in simple frames are sometimes replaced by confident DIYers, but sealed units and safety glass carry risks. A unit that is not packed correctly can make an opening sash drop or crack under load, and handling large panes is hazardous. A glazier also checks whether safety glass is required and that the new glass carries the correct marking.
Can you match obscure glass to my other windows?
Usually, yes. Obscure glass is made in many patterns, and the glazier can often identify yours from a photo or at the survey. Some older patterns are no longer made. If yours has been discontinued, the quote will offer the closest current pattern, or you can replace a matching set of panes so they all look the same.
