Broken shop window boarding for homes and businesses in Harrow
Broken toughened glass shatters into small pieces that can spread widely and sit in carpets and gaps for some time. Laminated glass cracks but stays in the frame, and is cut out with care. The glazier deals with each differently when making the opening safe.
The first job on an emergency visit is making the opening safe. Loose and hanging shards are removed from the frame, broken glass is cleared from floors and pavements, and anything that could fall is taken down before the opening is boarded or temporarily glazed.
Permanent glass is often made to order, especially toughened, laminated or sealed units, and cannot usually be cut from stock at the time. That is why emergency work is normally two visits: make safe now, then return to fit the permanent glass once it is ready.
Many home and business insurance policies include accidental damage or malicious damage cover for glass, sometimes with a set excess or a requirement to use approved contractors. Check your policy or call your insurer before agreeing to permanent work, so you know what will be covered.
What you get

Local details for Harrow
- Postcodes covered
- HA1, HA2, HA3, HA5, HA7 and the surrounding area, including Wembley, Northolt and Greenford
- Coast
- Harrow is well inland, around 50 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Harrow 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. Boarding blocks daylight, so in short winter days a boarded room can be very dark. Temporary clear glazing keeps light in, and on sunny elevations the permanent glass can include solar control or low-E coatings when it is ordered.
- Access and setting
- In busy streets, broken glass on pavements is a hazard to passers-by and needs clearing. Shopfronts may need boarding before trading, parking can be limited near the opening, and flats above shops often need boards fixed from inside.
- 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.

Choosing your emergency glazing
Polycarbonate temporary glazing
Clear, impact-resistant sheet fitted in place of the broken glass, keeping daylight in and the opening secure while permanent glass is made.
Permanent laminated glass
Laminated replacement glass that stays in place if struck again, often chosen for shopfronts and ground-floor windows after a break-in.
Permanent toughened glass
Toughened replacement glass for doors, low-level panes and other critical locations, made to measure after the opening is secured.
Emergency Glazing in Harrow: questions
What should I do immediately after a window is smashed?
Keep people and pets away from the broken glass, and do not try to pull out large hanging shards by hand. If it was a break-in or vandalism, call the police and note the crime reference. Take photos from inside and outside. Then call us, and we will tell you honestly when a glazier can attend to make it safe.
What causes glass to break without anything hitting it?
Glass can crack from thermal stress, when part of a pane heats up much more than the rest, often from sun, heaters or partial shading. Toughened glass can also break spontaneously in rare cases because of tiny inclusions in the glass. The glazier notes the crack pattern, which can help identify the likely cause.
Do you board up commercial premises and shopfronts?
Yes. We arrange boarding and temporary glazing for shops, offices, restaurants and other commercial premises. Large shopfront panes may need several boards, timber framing and more than one glazier. Once secured, we can quote for permanent glass, including laminated glass, and plan the fitting visit around your opening hours where possible.
Will the permanent glass need to be safety glass?
It will if the broken pane is in a critical location. In England, Approved Document K covers glass in doors and within 300mm of a door edge, up to 1500mm above the floor, and other glass within 800mm of the floor. The glazier checks the location when measuring, so the permanent glass meets the right standard.
