Whether your handle is broken or loose, hinges are misaligned or squeaky, or locks are stuck or damaged, our skilled technicians can diagnose the problem quickly.

In London, our standard response time for urgent repairs is typically within 1 to 2 hours from the moment you contact us. We recognize that a broken window or door can compromise your security, cause weather damage, or disrupt your daily routine, so we prioritize emergency calls. Our mobile team is equipped with a wide range of stock parts and tools to perform swift repairs on-site. For non-urgent repairs or scheduled maintenance, we offer flexible appointments that suit your convenience, but our priority remains to respond as fast as possible for urgent issues.
When repairs are carried out by our qualified technicians, they are designed to restore or even enhance the thermal insulation and energy efficiency of your windows and doors. Replacing worn or damaged seals, hardware, or glass ensures that your units are airtight and weatherproof, preventing drafts and heat loss. If your existing units are older or inefficient, we can advise on upgrading to modern, energy-efficient double or triple-glazed units, which significantly reduce heating and cooling costs. Our focus is on providing durable, high-quality repairs that maintain or improve your property’s insulation, saving you money on energy bills and creating a more comfortable indoor environment.
Yes, we specialize in replacing cracked, shattered, or broken window glass across all types of windows. Whether it’s a small crack, a large break, or complete shattering, our team can quickly remove the damaged pane and install a new, high-quality glass unit. We stock a wide variety of glass types, including toughened safety glass, laminated security glass, and standard single or double-glazed panes. Our goal is to restore the security, appearance, and insulation of your windows with minimal disruption, ensuring your property remains safe and secure.
Misted or fogged windows are a common sign that the seal within a double-glazed unit has failed, allowing moisture to enter and causing condensation between the panes. While minor misting can sometimes be temporarily addressed by resealing or reconditioning, in most cases, the most effective long-term solution is to replace the entire double-glazed unit. We specialize in replacing misted or fogged units with high-performance, energy-efficient alternatives that restore clarity, insulation, and aesthetic appeal. Replacing these units not only improves appearance but also enhances your property’s thermal efficiency, reducing energy costs.
Yes, we provide comprehensive repairs for window frames made from UPVC, aluminium, timber, or composite materials. Damaged or deteriorated frames can compromise the security, insulation, and appearance of your windows. We can fix issues such as rot, corrosion, dents, warping, or broken hardware. Our team can also re-seal, re-paint, or refurbish frames to restore their structural integrity and ensure they operate smoothly. Properly repaired frames improve the lifespan of your windows and maintain the aesthetic appeal of your property.
We work with virtually all common window styles used in residential and commercial properties, including casement, sash (both traditional and modern), tilt and turn, sliding sash, bay windows, tilt-and-slide, and large commercial units such as shopfronts and curtain walling. Our technicians are skilled in repairing hardware, replacing glass, and restoring the structural integrity of these various window types. No matter the style or complexity, we can provide tailored solutions to meet your needs.
Yes, safety glass such as toughened or laminated glass is used in all applicable situations to ensure safety and compliance with building regulations. For example, ground-floor windows, doors, and areas with high foot traffic or public access require safety glass to minimize injury risk if the glass breaks. We always recommend and install safety glass where appropriate, and our team can advise you on the best options based on your property and usage.
Yes, we replace both single-glazed and double-glazed units. For older or historic properties, single glazing might still be common, but we often recommend upgrading to double glazing for improved insulation, security, and noise reduction. Our team can carefully remove and replace existing glass units with modern, energy-efficient double-glazed panels, or supply single-glazed replacements where appropriate. We ensure that all replacements are fitted securely and sealed properly for long-lasting performance.
