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.

We Repair Any Sash Window And At An Affordable Cost

There are countless benefits that consumers within the greater London area can gain by turning to Mortice And Green for all of their sash window needs. We repair any sash window in this region, regardless of how extensive the reported damages happen to be. With our help, you can preserve these amazing building features, protect your property investment, beautify your abode, and limit your carbon footprint among many other things.

It is vital to understand that sashes can provide lasting value, but only when homeowners are careful to maintain them properly. This means that these systems should be inspected on a routine basis, and regularly painted and stained. Without this care, they will eventually begin to show signs of serious wear and tear. This is especially the case at the property exterior given that exposed wood will invariably succumb to the ravages of the natural elements.

Preventative maintenance is actually the best form of repair work that you can invest in. If the paint or stain on your sashes is looking a bit old, you definitely want to contact us. Keep in mind that this is unlike painting any other feature at the property exterior. This is because sashes are comprised of a number of separate, moving components that must work seamlessly together. If over spill is gotten on an one of these, you will have to deal with sticking windows. In fact, if your windows are currently sticking, you should call us now to have them restored to their normal level of functioning and their original aesthetic beauty. We can add protective and cosmetic coatings to sash wood without compromising the mobility of individual, moving parts.

It may be that you’ve recently discovered a broken sash cord in one of your sash windows. Surprisingly, sashes can continue functioning for a short period of time with just a single functional cord. The downside of this fact is that it is incredibly dangerous to use them. You have probably noticed that sashes are quite heavy. In fact, you’d be very hard put to find a heavier window design that’s commonly installed in residential window properties. The single, remaining cord is going to have to bear all of this weight on its own. This means that it is definitely going to wear down a lot quicker. Within a short period of time, this extra friction, pressure and stress is going to cause the remaining cord to snap as well.

By waiting to take care of a repair like this one, you will end up having to replace two damaged cords rather than just the one. The most important thing to know, however, is that when the remaining cord does break, the heavy window will come crashing down. This can lead to a damaged frame, broken glass and serious physical injuries should anyone happen to be in the vicinity at the time of this event. More often than not, we will replace all cords so that the entire system is in good condition for a very long time to come.

Perhaps the biggest problem with poor maintained windows is wood rot. Wood rot can cause a host of problems with both these windows themselves and the building entire. As such, you want to make sure that the company working on this type of repair is committed to providing the most needs-specific solution. There is no one-size-fits-all remedy for this problem. Each window must be addressed on an individual basis, particularly in instances when the primary goal of homeowners is preserving as much of a home’s original construction as possible.

One major benefit of working with us on restoration projects like these is that we have a considerable amount of experience in preserving dated windows, without undermining their overall integrity and durability. We know which materials must be discarded, and which can be restored and retained. We also understand that in certain instances, rebuilding historic windows from start to finish makes the best sense. Best of all, we can complete these projects according to the original window design so that your new sashes will not be distinguishable from the ones that were initially installed in the home. We will talk you through our repair and restoration plans as well, so that you can have a clear understanding of the benefits and drawbacks of each decision. This allows consumers to make informed choices concerning the look and the functionality of their windows, as well as the impact that these will ultimately have on their overall property values.

We even make a few, special finishing touches to ensure a truly authentic and historic look. For example, we always take care to save and restore the original hardware when possible. If you are less concerned about authenticity and simply want to take advantage of the latest advancements in these products, we can tell you all about the latest innovations in these window designs. For instance, homeowners can now invest in double glazed sashes that have the same traditional beauty that these windows are known for, even as they provide far higher levels of insulation and efficiency. They can also choose to do away with dated lead weight and cord systems in favor of new cords and springs. We are capable of installing all types and styles of sash windows and will ultimately provide the solution that works best for you. We even offer innovative draught proofing systems for making these products far more efficient and better able to block out noise and air pollution.

Keep in mind that we are committed to always taking a hands on approach with all of our work. This means that absolutely no parts of your repair project will ever be outsourced. If we aren’t taking care of this work directly on your property, we will be working on your windows right in our very own workshop. This is how our quality control remains so high and why we are always willing and able to stand behind the sashes that we repair, restore and produce. At Mortice And Green, we love what we do and it definitely shows in the results we provide.

Sash Windows in the Balance

There are many styles of sash window but all have one common denominator, they all have an operation that requires the weight of the window to be supported to allow ease of opening.

The earliest examples of the sliding sash window had an operation whereby the window would slide horizontally without need for the window to be supported but since around the 18th century most sash windows were designed to slide vertically.

Traditional œhung sash windows reply on a weight system with each window connected to sash cords that are strung over a pulley wheel and attached to a cast iron weight inside the box frame. This cast iron weight is approximately half the weight of the sliding sash, with one on each side they equal the same as the sash window. With the weight of the window balanced by the sash weights the window will lift open and stay open in whatever position the user may choose.

Modern sash windows can sometimes utilise a system referred to as the spiral balance mechanism. The spiral balance is effectively a metal rod that runs up the centre of a strong spring connected at one end. The spring and rod assembly is shrouded within a plastic tube to keep it straight and also for cosmetic reasons. The spring is connected to the box frame sash window run by a screw and the spring is tensioned by turning the metal rod against the spring thus creating tension. Much like some cheap weight lifting and fitness machines the spring mimics the action of gravity by the pulling force of the tensioned spring.

Both sash window balance systems work well but neither a failsafe and will certainly require repair and maintenance over the years.

The most reliable system is, as most professional sash window experts will tell you, the traditional weighted sash window system.

The most common issue with a box sash window is broken sash cords but other problems can occur especially if you replace glass. Older box sash windows will have been weighted for 3mm glass, modern glass is 4mm for safety reasons. This means that if you ever need to re-glaze an old sash window the glazier will no doubt use 4mm glass and you will then unwittingly have increased the windows weight by around 25% The window will then require the sash balance weights to be adjusted to ensure the window still functions as intended. The same would go for spiral balanced windows although the remedy would be simpler as you would only need to increase the tension on the spring to account for the twenty five percent increase in the sash windows weight.

If your sash windows seem to drop closed when you open them or if the top sash slide open on its own then it is likely that you will need either sash cord repairs and or sash window make weights added to the existing sash weights.
