Swiss Cottage, nestled in the London Borough of Camden, is a lively and architecturally rich area that blends classic period homes with modern city living. With its leafy avenues, Victorian terraces, Edwardian mansions, and striking Georgian conversions, the district reflects London’s long tradition of elegant craftsmanship and design. Many properties here still feature original sash windows, wooden doors, and ornate joinery, which contribute greatly to the area’s distinctive charm. At Traditional Sash Windows and Carpentry, we specialise in restoring, repairing, and creating bespoke timber joinery that enhances both the beauty and efficiency of Swiss Cottage’s homes.
Our skilled craftsmen have worked on properties throughout Swiss Cottage and neighbouring areas such as Belsize Park, St John’s Wood, and Hampstead. Whether your home is a Georgian townhouse near Avenue Road, a Victorian flat conversion on Fairfax Road, or an Edwardian residence overlooking Primrose Hill, we offer tailored joinery solutions that combine timeless craftsmanship with modern performance.
Sash windows are one of the defining features of Swiss Cottage’s historic homes. Their elegant proportions, slim timber profiles, and smooth sliding mechanism add a sense of refinement that few modern designs can match. Over time, however, exposure to London’s weather can cause frames to warp, cords to fray, and paintwork to deteriorate. Our sash window restoration service is designed to reverse this wear, ensuring your windows operate smoothly, insulate effectively, and look as beautiful as the day they were first installed.
We begin with a full on-site assessment to determine the extent of any repairs. Our joiners then carefully remove and restore each sash, repairing or replacing damaged timber using sustainable hardwoods such as Accoya or Red Grandis. Each window is re-corded, balanced, and fitted with discreet brush seals to eliminate draughts and rattles. For homeowners seeking additional warmth and sound insulation, we also provide double-glazed sash replacements and secondary glazing, perfect for busy streets like Finchley Road or for listed buildings where external changes are restricted.
Every restoration is carried out with precision and respect for the property’s heritage, ensuring the finished result retains the charm and proportions of the original design.
A well-crafted wooden door is a defining feature of many Swiss Cottage homes, whether it’s an ornate Victorian entrance with stained glass, a solid Georgian panelled door, or a pair of elegant French doors leading to a terrace. At Traditional Sash Windows and Carpentry, we create bespoke wooden doors that perfectly complement your home’s architecture while incorporating modern security and thermal benefits.
All of our doors are handcrafted in our Kent workshop using traditional mortise and tenon joinery, ensuring exceptional strength and durability. We design everything from classic front doors and stable doors to patio and bi-folding doors, all made to measure and finished with high-quality ironmongery and coatings that protect against weather and wear.
We also restore existing doors, repairing damaged panels, adjusting frames, and refinishing surfaces to revive their original elegance. Whether you wish to restore an Edwardian front door on Winchester Road or commission a new one for a contemporary townhouse near Belsize Park, we can craft a bespoke solution that blends authenticity with modern practicality.
While Swiss Cottage’s period homes offer undeniable charm, they are not always known for their insulation. Our draught proofing service provides an effective way to make your home more comfortable without altering its appearance.
We fit fine brush seals around sash windows and doors to stop cold air from entering and warm air from escaping. This subtle addition prevents rattling and improves energy efficiency throughout the home. When combined with secondary glazing, it creates a powerful barrier against both heat loss and external noise, ideal for properties close to busy roads or train lines.
Our draught proofing solutions can be carried out as part of a complete window overhaul or as a standalone service, giving homeowners flexibility depending on their needs. The result is a home that feels warmer, quieter, and more comfortable while still retaining its period character.
At Traditional Sash Windows and Carpentry, we are passionate about preserving traditional joinery techniques while taking advantage of the durability offered by modern materials. Each piece of joinery we produce is made by hand, with careful attention paid to every joint, moulding, and detail.
We use sustainable timbers such as Accoya and Red Grandis, which are resistant to rot, swelling, and warping. Every product is finished with breathable coatings that protect the timber from moisture and allow it to age gracefully. This approach ensures our work not only complements your home’s original design but also stands up to the demands of London’s changing climate.
Our joinery blends heritage craftsmanship with the performance expected in modern homes, ensuring your windows and doors remain functional, beautiful, and efficient for decades to come.
We offer a comprehensive range of joinery and restoration services throughout Swiss Cottage and nearby areas including Belsize Park, St John’s Wood, Hampstead, and West Hampstead. Our team has worked on properties ranging from Georgian mansions and Edwardian townhouses to mid-century terraces and modern conversions.
Every project begins with a detailed consultation to understand your home’s architecture and your specific requirements. Whether you need a full sash window restoration, bespoke double-glazed replacements, or new timber doors, we tailor every detail to suit your property and lifestyle.
As a family-run business, we take pride in our commitment to clear communication, reliability, and exceptional workmanship. Our reputation across London and Kent has been built on trust, attention to detail, and an unwavering dedication to quality joinery.
Sustainability is central to our approach. Wherever possible, we repair existing joinery rather than replacing it, preserving original craftsmanship and reducing waste. When new timber is required, we use responsibly sourced materials and low-VOC coatings that protect the wood while minimising environmental impact.
Our preferred timber, Accoya, is one of the most sustainable and stable materials available. With a lifespan of up to 50 years above ground, it provides outstanding durability and performance, making it an excellent choice for London homes exposed to fluctuating temperatures and humidity.
By choosing our services, you are not only investing in quality joinery but also supporting environmentally responsible practices that ensure your home remains both beautiful and sustainable.

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.
Traditional Sash Windows and Carpentry works throughout the whole of Kent and London, including Ramsgate, Broadstairs, Margate, Canterbury, Whitstable, Herne Bay, Deal, Sandwich, Dover, Folkestone, Maidstone, Tonbridge and surrounding areas. We also take on selected projects further afield where the scope of work is suitable.
