Whitehall is one of London’s most historic and prestigious areas, lined with grand architecture, stately government buildings, and elegant townhouses that reflect centuries of craftsmanship. Many of these properties still retain their original sash windows and solid wooden doors, features that add depth and authenticity to their appearance. At Traditional Sash Windows and Carpentry, we specialise in the restoration, repair, and replacement of these classic elements, ensuring homes and heritage buildings in Whitehall continue to look their best while benefiting from modern levels of comfort and efficiency.
Our experienced team has carried out work across Central London, including the Whitehall area, where precision and sensitivity to historic detail are essential. We combine traditional joinery skills with modern technology to produce results that respect the architecture while improving performance, insulation, and security.
Whitehall’s buildings are among the most recognisable in the capital, with their tall sash windows and distinctive stone or brick facades. Over time, these windows can develop issues such as broken cords, rattling frames, or timber decay caused by London’s weather and pollution. Our sash window restoration service provides a thorough and sympathetic approach to repair and renewal.
Each window is carefully dismantled and inspected before any repairs begin. We replace damaged timber with matching hardwoods such as Accoya or Red Grandis, ensuring a seamless blend with the original design. Sashes are rebalanced, cords are replaced, and discreet brush seals are installed to eliminate draughts and improve energy efficiency. For properties where higher performance is required, we offer double-glazed sash replacements or secondary glazing, maintaining the historic look of the window while improving insulation and noise reduction.
The buildings around Whitehall range from grand government offices and Georgian townhouses to later Edwardian and Victorian properties. Each has its own unique joinery features, particularly in the design of the front doors. We create bespoke wooden doors that complement your property’s architecture, combining the look of period craftsmanship with modern reliability.
Every door is handcrafted in our Kent workshop from sustainable timber, built using traditional mortise and tenon joinery for exceptional strength. We can replicate historic designs exactly or produce contemporary interpretations that suit modern refurbishments. We also offer full restoration services for existing doors, including re-alignment, re-finishing, and weatherproofing to extend their lifespan and restore their elegance.
Many of Whitehall’s period properties, particularly those with older sash windows, are prone to draughts and heat loss. Our draught-proofing service offers a simple and effective way to improve comfort without altering the building’s appearance. We install slim brush seals within the existing joinery to stop cold air entering and warm air escaping, while allowing the sashes to slide smoothly.
This process makes a noticeable difference to warmth and quietness, particularly in central London locations where traffic noise and winter winds are common. Draught proofing can be carried out alongside repairs or as part of a larger restoration, offering excellent results without the need for replacement windows.
At Traditional Sash Windows and Carpentry, we take pride in combining heritage techniques with modern precision. Every piece of joinery is made or restored using traditional mortise and tenon joints, which provide strength and stability unmatched by modern shortcuts. Our team has decades of experience working on heritage buildings, understanding the unique requirements of London’s historic architecture.
We use premium materials such as Accoya and Red Grandis, chosen for their durability, dimensional stability, and resistance to decay. Each window or door is finished with specialist coatings that protect against moisture, sunlight, and pollution, ensuring it continues to look beautiful for years to come. Our attention to detail ensures that every project we complete in Whitehall meets the highest standards of craftsmanship and authenticity.
Our services are available throughout Whitehall and the surrounding areas, including Westminster, St James’s, and Victoria. These locations share a mix of heritage buildings and more modern conversions, each requiring an experienced joiner’s touch. Whether you need a single sash restored in a listed townhouse or a full set of bespoke timber windows for a renovation project, our team provides the same care and dedication to every job.
We understand the importance of balancing tradition with functionality, especially in high-value properties where appearance and performance must align. From survey to completion, we work closely with clients, architects, and property managers to ensure smooth and professional delivery.
Our approach is guided by a commitment to sustainability. We work with responsibly sourced timber and favour repair over replacement wherever possible. Restoring existing windows and doors not only retains original craftsmanship but also reduces environmental impact. When replacements are necessary, we use long-lasting, low-maintenance timbers like Accoya, which offer exceptional resistance to weathering and decay.
This combination of traditional methods and eco-conscious materials ensures every project provides lasting quality and value. Our finishes are chosen to withstand London’s environmental conditions, protecting against moisture and pollution while preserving the natural beauty of the wood.
Whitehall’s properties often fall under conservation or listed-building regulations, which require specialist knowledge and careful attention to detail. Our team has extensive experience working on such properties, liaising with conservation officers and ensuring all repairs and replacements meet the necessary requirements. We can replicate historic profiles, glazing bars, and mouldings precisely, keeping the architectural integrity of the building intact.
We understand the importance of maintaining original aesthetics while incorporating modern improvements where possible. Our approach ensures that your property retains its character while performing to today’s standards of efficiency and comfort.

We repair, restore and replace traditional timber windows and doors across Kent and London. Our work includes sash window overhauls and draught proofing, timber resin repairs, replacement sashes, new box sash windows, casement window repairs, secondary glazing, double glazed sash windows, wooden door repairs, replacement doors and bespoke joinery.
Where possible, we always aim to repair and retain original timber windows. Many older sash windows can be brought back into good working order with careful timber repairs, replacement sections, new cords, pulleys, beads, glazing repairs and draught proofing. Full replacement is usually recommended only where the existing frame or sashes are beyond economical repair, or where a customer would benefit more from entirely new joinery.
Yes. Our sash window overhaul and draught proofing service is designed to reduce rattling, draughts and heat loss while preserving the character of traditional windows. We can also discuss slimline double glazing, standard double glazing where suitable, secondary glazing and Fineo vacuum glazing, depending on the building, existing joinery and planning requirements.
Yes. We regularly work on period homes, listed buildings and properties within conservation areas. Our approach focuses on retaining as much original timber and architectural detail as possible, using traditional joinery methods alongside modern repair materials where appropriate. We can produce like for like replacement components, including mouldings, glazing bars, curved heads and bespoke sash profiles.
The right timber depends on the property, design and budget. We commonly use Accoya, Sapele and European Oak, along with other suitable hardwoods and softwoods where required. Accoya is a popular choice for painted external joinery because it is highly stable and durable, while Sapele and Oak can be well suited to particular repairs, doors and specialist joinery details.
Our repairs and new joinery are supplied properly prepared and undercoated where required, ready for final decoration. We do not generally provide the final painting service, as this is best completed by a dedicated decorator once the timber has fully settled and any surrounding finishes have been prepared. We will always explain what stage the joinery will be left at before work begins.
We offer surveys and quotations for suitable projects across Kent and London. During the visit, we assess the condition of the windows, doors or joinery, discuss the options available and explain the likely repair or replacement work involved. For some smaller jobs, clear photographs and measurements may be enough for us to provide an initial estimate before arranging a site visit.
This depends on the number of windows, their condition and the level of repair needed. A straightforward overhaul and draught proofing job can often be completed in a day, while larger restoration projects, replacement sashes or full house installations may take longer. We will provide a clear programme before work starts so you know what to expect.
Yes. Traditional Sash Windows and Carpentry is fully insured and CERTASS certified, giving customers added confidence that their project is being completed by an experienced and properly accredited team. CERTASS certification allows us to self certify qualifying replacement window and door installations, helping ensure the work meets current Building Regulations requirements without the need for the customer to arrange separate Building Control approval. Once the installation is complete, the relevant certification can be provided for applicable work.We also hold appropriate public liability insurance for the work we carry out, including sash window repairs, replacement timber windows, wooden doors, glazing and bespoke joinery.
Yes. We supply and fit bespoke secondary glazing for sash windows, casement windows and other traditional timber windows throughout Kent and London. It is a practical way to improve warmth, reduce outside noise and limit draughts without removing or altering the original joinery.Secondary glazing is fitted internally, creating an additional barrier behind the existing window. This makes it especially useful for period homes, listed buildings and conservation areas where replacing original windows may not be appropriate. We can advise on discreet systems that suit the style, layout and day to day use of your windows, including horizontal sliding, vertical sliding, hinged and fixed options where suitable.
