About replacement sealed units in St Albans
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.
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.
When a double glazed unit sits in a critical location, both panes need to be safety glass, not just the one facing the room. A unit with toughened glass on one side and ordinary float glass on the other does not give safe breakage from both directions.
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.
What a typical job includes
- Removal of old glass and packaging from site
- Fitting on glazing packers with the beads refitted
- Made-to-measure glass or sealed unit to suit the frame
- Survey and measurement of the existing glass or unit

- AL1, AL2 and the surrounding area, including Harpenden, Hatfield and Hemel Hempstead
- Coast
- St Albans is well inland, around 59 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In St Albans 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.

Listed buildings in England need listed building consent for most changes to historic windows or glass, and conservation areas can restrict changes visible from the street. Speak to the council's conservation officer before ordering.

Replacement Glass in St Albans: questions
Does replacing window glass need building regulations approval?
Replacing only the glass in an existing frame is normally treated as a repair in England and does not need to be notified. Replacing the whole window is different and must go through building control or a competent person scheme. Even for glass-only work, safety glass should be used in critical locations, and the detail of the rules differs between UK nations.
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.
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.
Do I need safety glass in my replacement window?
You do if the glass is in a critical location. In England, that means glass in doors and within 300mm of a door edge, up to 1500mm above floor level, and other glass within 800mm of the floor. Elsewhere in the UK the rules are similar, but the detail differs between nations. The glazier checks each location at the survey.
