Why Mortice & Green Is the Trusted Choice for Sash Window Repairs and Restoration in London
Sash windows are one of the defining features of London’s period properties, adding timeless elegance and architectural character to homes across the capital. However, years of exposure to the elements can leave even the highest-quality timber windows suffering from draughts, rattles, broken cords or deteriorating timber. While some homeowners assume replacement is the only option, professional restoration can often return original sash windows to excellent condition while preserving the unique charm of the property.
Choosing the right company is essential to achieving long-lasting results. Sash window restoration requires specialist knowledge, traditional joinery skills and a thorough understanding of historic buildings. At Mortice & Green, we have been providing expert sash window repairs and restoration in London since 1994, helping homeowners protect and enhance their original timber windows through quality craftsmanship, honest advice and exceptional customer care.
More Than 30 Years of Specialist Experience
Experience plays a vital role when restoring traditional sash windows.
Every period property is different, and original timber windows often require a tailored approach rather than a one-size-fits-all solution. Understanding traditional construction methods, historic joinery techniques and the way older timber behaves allows experienced specialists to carry out repairs that preserve both appearance and functionality.
Since being established in 1994, Mortice & Green has successfully restored, repaired and manufactured sash windows for homeowners throughout London. This extensive experience allows our team to diagnose problems accurately and recommend the most appropriate solution for every property.
Preserving Original Character Wherever Possible
Many original sash windows can be restored rather than replaced.
Instead of removing historic features unnecessarily, professional restoration focuses on repairing damaged timber, replacing worn components and improving performance while retaining the window’s original appearance. This approach helps preserve the architectural integrity of period homes while extending the lifespan of existing windows.
Where replacement is genuinely required, bespoke hardwood reproduction windows can be manufactured to match the original design, ensuring the property retains its traditional character.
Our aim is always to preserve as much of the original craftsmanship as possible.
Comprehensive Sash Window Services
Sash windows can develop a wide variety of issues over time, each requiring specialist attention.
At Mortice & Green, we provide a complete range of services, including sash window repairs, refurbishment, renovation, draught proofing, sash cord replacement, wooden window restoration, bespoke hardwood sash windows and replacement windows where necessary.
Whether a window is difficult to open, suffers from rattling, has damaged timber or requires improved thermal performance, our experienced restorative joiners have the expertise to deliver the right solution.
This comprehensive service allows homeowners to address multiple issues while working with one trusted specialist.
Improving Comfort Without Losing Character
One of the most common complaints about traditional sash windows is heat loss and unwanted draughts.
Professional restoration can significantly improve comfort without compromising the appearance of the windows. During refurbishment, discreet draught-proofing systems are integrated into the parting and staff beads, reducing rattles while helping improve insulation and heat retention.
For homeowners looking to enhance energy efficiency further, existing sash windows can often be upgraded with slimline double glazing while preserving their original style.
These improvements allow period properties to enjoy modern comfort while maintaining their historic charm.
Specialists in Conservation Areas and Listed Buildings
Many London homes are located within conservation areas or are listed buildings, meaning window work often requires specialist knowledge.
Mortice & Green has extensive experience working on properties where preserving the original appearance is essential. Our bespoke hardwood reproduction windows are carefully manufactured to match existing proportions, profiles and detailing, helping satisfy conservation requirements where replacement is necessary.
We also advise homeowners on planning considerations and listed building requirements, providing confidence that work is carried out sympathetically and professionally.
This expertise makes us a trusted choice for period property owners across London.
Honest Advice Every Time
Choosing between repairing and replacing sash windows can sometimes be difficult.
At Mortice & Green, we believe every customer deserves honest, straightforward advice based on the condition of their windows rather than the most profitable option. We carefully assess each property before recommending the most appropriate solution, ensuring homeowners receive practical advice tailored to their individual needs.
This transparent approach has helped us build long-term relationships with clients who value quality workmanship and genuine expertise. Providing the right solution, not simply the most expensive one, has always been central to our business philosophy.
Skilled Craftsmanship That Stands the Test of Time
Restoring sash windows successfully requires exceptional attention to detail.
From replacing worn sash cords and pulley wheels to repairing timber and balancing window weights, every stage of the restoration process must be completed with precision. High-quality workmanship not only improves the appearance of the windows but also ensures they operate smoothly and continue performing reliably for many years.
Our experienced restorative joiners take pride in every project, delivering repairs and restorations that combine traditional craftsmanship with modern techniques where appropriate.
The result is beautifully restored windows that complement the character of your home while offering improved performance.
Family Values and Personal Service
As a small, independent family-run business, Mortice & Green offers a level of personal service that larger national companies often struggle to match.
Every project is approached with care, professionalism and a genuine commitment to customer satisfaction. From the initial survey through to the completed installation or restoration, clients receive clear communication, reliable service and meticulous attention to detail.
By maintaining the same values established when the company was founded, we continue to provide a service built on trust, craftsmanship and long-term customer relationships.
