Emergency Glazing
Our emergency glass repair service addresses urgent glazing problems affecting homes, offices and retail premises. Available around the clock, we secure exposed openings, stabilise damaged glazing and install protective boarding when immediate replacement is impractical. We also measure and arrange suitable replacement panes, including double-glazed units, toughened glass and laminated safety glass, where required.
Shopfront Glazing
We provide emergency and planned shopfront glazing, replacing damaged display windows, entrance glass and commercial frontage panels across London. Our 24/7 service includes making unsafe areas secure and installing temporary boarding where necessary. We supply appropriately specified toughened, laminated and double-glazed replacements, with measurements and access requirements carefully assessed before installation.
Door Glass Replacement
We replace cracked, shattered and failed glazing in patio, French and front doors, including uPVC, timber and aluminium systems. Our service covers safety glass and made-to-measure double-glazed units. We assess the existing frame, measurements and safety requirements before arranging replacement. Where suitable, we replace damaged glass without removing the complete door.
Commercial Glazing
We provide commercial glazing repairs, replacements and maintenance for offices, shops and managed buildings. Our services cover damaged windows, entrance glass, failed double-glazed units and safety glazing. We assess existing frames and glass specifications before recommending suitable remedial work. Emergency make-safe and boarding services are also available for premises affected by broken glazing.
Cat Flap Installation
Our pet flap fitting service covers various door materials, glazing systems and suitable walls. We carefully examine the existing construction before selecting an appropriate installation method, including made-to-measure replacement glass where necessary. Customers can choose from manual, microchip, locking and smart-style flaps. We also undertake pet flap replacements, removals and compatible upgrades, with straightforward installations starting from £95.
Double Glazing Repairs
We replace misted, cracked and failed double-glazed units with accurately measured, made-to-measure glass. Our service addresses condensation, cloudiness and moisture trapped between panes caused by seal failure. Where existing uPVC, timber or aluminium frames remain suitable, we retain them. Each replacement is assessed for correct dimensions, thickness, spacer specifications and glass requirements.
Window Repairs
Our window repair services address cracked panes, misted glazing, defective fittings and windows that cannot close securely. We examine each issue to identify suitable glass or hardware repairs without replacing the entire window unnecessarily. Failed sealed units can be replaced separately where frames remain sound. Emergency assistance is available around the clock for unsafe glazing.
Rooflight & Skylight Glass
Our rooflight and skylight glazing services address cracked, damaged and failed glass in homes and commercial premises across London. We carefully remove the affected glazing before fitting replacement glass. Professional sealing forms an essential part of our replacement process. We undertake each stage of the work with particular attention to safe removal and proper installation.

Great service from M25 Glazing. The glass in our shop door was badly smashed and the team responded quickly, removed the broken glass and replaced it professionally. The new glass looks great and the whole job was completed neatly and efficiently. Would definitely recommend M25 Glazing.
