A smashed shopfront can leave your premises exposed in minutes. Knowing how to board a damaged shopfront gives you a short-term way to protect stock, reduce weather damage and make the entrance less accessible while a professional repair is arranged. The priority is not making the frontage look finished. It is making the property safe, secure and ready for proper glass or door replacement.
If broken glass is still falling, a frame is unstable, or the opening leads directly onto a busy pavement, do not attempt a DIY board-up. Keep people away from the area and arrange emergency help. A temporary boarding job is only useful when it does not create a new risk for staff, customers or passers-by.
First, make the damaged shopfront safe
Before measuring timber or reaching for tools, assess the immediate danger. Move customers and staff away from the frontage, especially where toughened glass has shattered into small pieces or laminated glass is cracked but still hanging in place. Put up a clear barrier if you can do so without getting close to loose glass.
Wear sturdy footwear, cut-resistant gloves and eye protection. Avoid lifting large panes, pushing cracked glass from the frame or sweeping shards with bare hands. Small pieces can travel further than expected, particularly around door tracks, display areas and entrance mats. Use a brush and shovel for accessible debris, then place broken glass in a rigid, clearly labelled container rather than a thin rubbish bag.
If the damage followed a break-in, do not touch items that may be needed as evidence until you have spoken with the police or your insurer. Take photographs from a safe distance, including the opening, frame, locks and any damaged stock. These records can make the claims process easier and help a glazing team understand what is needed before arrival.
How to board a damaged shopfront for temporary security
Boarding should cover the opening fully and be fixed to sound material, not to cracked glass or a weak aluminium frame. Exterior-grade plywood is normally the practical choice because it is strong, easy to cut and more resistant to rain than standard interior board. Thin hardboard, chipboard and loose sheets of plastic are poor substitutes. They can split, bow or come away in wind.
Measure the clear opening at several points. Shopfronts are not always perfectly square after an impact, so use the widest measurement for the width and height. Add enough overlap for the board to sit securely over solid sections of the frame or surrounding wall. If there is a recessed doorway, make sure the board protects both the glass and any damaged locking area.
For a small, straightforward opening, hold the plywood in position and mark the fixing points where there is solid timber, masonry or a stable structural frame. Use suitable screws and washers rather than nails. Screws hold more reliably and are easier to remove when replacement glazing is fitted. Fix around the perimeter at regular intervals, checking that the board is firm but not tightening anything against unstable glass.
Do not screw through a live electric shutter, door closer, alarm cable, intercom unit or metal frame unless you are certain it is safe to do so. In many commercial properties, the best fixing method depends on the shopfront system and the condition of the surrounding structure. A poorly placed screw can damage wiring, compromise a shutter or turn a glazing repair into a more expensive door or frame repair.
Once fitted, check the board from inside and outside. It should not rattle, leave hand-sized gaps or obstruct a required emergency exit. If the shop has more than one entrance, make sure staff can still leave safely. Security matters, but fire escape routes must remain usable and should never be boarded over.
Do not board over hazards
Temporary boarding is not suitable for every situation. Call a professional instead if the opening is above ground level, the damaged panel is part of a curtain wall, the shopfront frame is bent, or a glazed door cannot be closed and locked. The same applies if the glass is in a fire-rated screen, a communal entrance or a property with roller shutters that have been damaged in the same incident.
A board can conceal the problem for a few hours or days, but it cannot restore the strength, appearance or weather resistance of a correctly glazed shopfront. It should be treated as a temporary security measure, not a repair.
Protect the inside of the premises
After the opening is covered, protect stock and fittings near the frontage. Move valuable or water-sensitive items away from the damaged area, particularly if rain is expected. Cover displays with clean sheeting where necessary, but keep walkways clear for staff, emergency services and repair technicians.
Check for water around sockets, extension leads and illuminated signs. If rain has entered or glass has damaged electrical equipment, isolate the affected circuit if it is safe to do so. Do not use electrical equipment that has become wet or has visible impact damage.
It is also worth checking the alarm and CCTV systems. A break-in can damage door contacts, camera cables and sensors even when they appear intact. Let your monitoring provider know that the frontage has been temporarily secured, and ensure their contact details are current while repairs are underway.
Keep the business secure overnight
A boarded shopfront can attract attention, so make it clear that the premises are still protected. Switch on internal lighting where appropriate, keep valuables out of sight and remove cash from tills. If the board covers a customer entrance, place a simple notice at a safe location explaining whether the business is trading through another door or temporarily closed.
Do not leave tools, ladders or leftover timber outside. These can be used to gain access or cause an obstruction on the pavement. Inspect the board before closing and after severe wind or heavy rain. If it shifts, swells or becomes loose, it needs attention straight away.
For landlords, facilities managers and letting agents, record the time of the incident, photographs, temporary works completed and the name of anyone who attended. This creates a clear handover for the tenant, insurer and repair contractor. It also helps when several parties are responsible for approving the permanent work.
Arrange the permanent repair quickly
The faster replacement glass or a new door section is installed, the sooner your shop can return to normal. When contacting a glazing company, explain the type of damage, the approximate size of the opening, whether the frame is intact and whether the site is currently secure. Photos are useful when they can be taken safely.
A professional will assess whether the shopfront needs a like-for-like replacement, toughened safety glass, laminated security glass, double glazing or a repair to the frame, locks or door hardware as well. The right option depends on the existing shopfront, your security needs, building requirements and budget. For example, laminated glass can remain in place after impact, while toughened glass breaks into smaller pieces. Neither is automatically right for every retail setting.
For London businesses facing a break-in, accident or vandalism, Glazing Squad can provide emergency attendance, temporary boarding and follow-on shopfront repairs. Fast protection is useful, but experienced fitting is what restores the security, appearance and day-to-day operation of your premises.
A damaged frontage is disruptive, especially when you are trying to protect stock and reopen for customers. Secure the area without taking unnecessary risks, then arrange a proper repair as soon as possible so your shop can look open, safe and ready for business again.
