Clapton Glass & Joinery – trusted local glaziers and sash window specialists in East London and Essex for over 50 years.
Sash Window Specialist
Sash Windows
QUALITY AND CRAFTSMANSHIP COMBINED
Traditional timber sash windows and box frame sash windows are a defining feature of many period, Victorian, Edwardian, and Georgian properties across London and the Home Counties. We regularly work throughout East London, including Hackney, Clapton, Stoke Newington, Islington, as well as Wimbledon, Richmond, Essex, and surrounding areas.
We specialise in bespoke sash window design, manufacture, installation, repair, and refurbishment, offering traditional joinery that is fully sympathetic to period architecture and conservation area requirements. Our services include sash window repairs, box frame restoration, draught proofing, glazing upgrades, and full sash window replacement, all finished to the highest standards of craftsmanship and durability.
As experienced local sash window specialists and traditional glaziers, we combine time-served skills with modern performance solutions to enhance comfort, efficiency, and appearance while preserving the character of your property.
And... we know the area
We understand that different areas of London and the Home Counties, as well as different property types, require specific window styles and designs. That’s why we offer an extensive range of sash window and glazing solutions to suit the architectural character of your home and the requirements of your local area.
In most cases, our traditional sash windows and box frame replacements can be installed without the need for planning permission, making it easier to upgrade your windows while maintaining the original appearance of your property.
Local Glazing Specialist
Glass & Glazing
We supply and fit a full range of toughened, laminated, safety, and decorative glass, as well as glass doors, mirrors, and bespoke glazing solutions. We hold an extensive selection of replacement glass in stock, allowing us to cut glass to size quickly and accurately to meet your requirements.
We manufacture sealed glass units to any size, shape, or specification, including toughened sealed units and triple glazed units. No job is too big or too small, and we work with both residential customers and larger-scale commercial sealed unit users.
With over 50 years of experience in glass replacement and glazing, we are also able to carry out urgent and emergency glass repairs when required.

How We Work
FROM APPROVAL TO INSTALLATION
Once you’re happy to go ahead, we’ll issue our initial invoice and arrange a second visit to confirm all final measurements and technical specifications before work begins. A 50% deposit is then requested to secure your project.
​
Our typical sash window turnaround time is 4–6 weeks, although we always do our best to accommodate urgent or time-sensitive projects. Once manufacturing is complete, we’ll confirm a delivery and installation date that works around your schedule.
GOALS & EXPECTATIONS
We can take measurements over the phone or visit you in person, and we’ll provide a clear quote within 24 hours. We’ll listen to your ideas and guide you to the right glazing solution, no matter how big or small your project.
INSTALLATION, COMPLETION & PEACE OF MIND
Before starting work, we’ll agree arrival and departure times that fit around your day, ensuring minimal disruption while we complete the project to the agreed specification.
Once finished, we’ll carry out a full walkthrough with you to ensure everything meets our high standards, leaving your home or business clean, tidy, and finished to perfection. Finally, we’ll arrange the issue of your FENSA certificate, giving you complete peace of mind in the quality and compliance of our workmanship.
