Kensington is one of London’s most distinguished neighbourhoods known for its elegant terraces, leafy avenues and refined townhouses that span Georgian, Victorian and Edwardian eras. From the quiet residential pockets around Campden Hill to the grand stucco fronted façades near Kensington Palace the area showcases architecture rich in detail and craftsmanship. Many of these buildings still feature original sash windows, wooden doors and bespoke joinery that form an essential part of their identity. These traditional elements help define Kensington’s architectural rhythm yet they require specialist care to preserve their appearance and function. At Traditional Sash Windows and Carpentry we work throughout Kensington restoring period joinery, improving comfort with draught proofing, upgrading glazing and creating handcrafted timber features that complement the character of every home.
Kensington’s sash windows are among its most recognisable features. Whether they are slender Georgian designs with fine glazing bars or the taller Victorian sashes found along Kensington Church Street these windows contribute greatly to the harmony of the area’s buildings. Many have been in place for decades which means they have endured changes in temperature, shifting masonry and exposure to London’s climate. Timber may soften, joints can loosen and sash cords often reach the end of their lifespan. Our restoration process begins with a detailed assessment of each window so that we understand its structural and aesthetic condition. Wherever possible original timber is carefully repaired and retained. When new sections are required we use sustainable hardwoods shaped to match the profiles of the existing joinery. Pulleys are serviced, weights are rebalanced and cords are replaced so each sash moves smoothly while retaining its historic charm.
Kensington’s traditional homes can be susceptible to cool draughts especially during winter when older timber frames allow small amounts of air to pass through. Even well maintained windows may benefit from discreet improvements. Our draught proofing system is subtle, using slim brush seals fitted within the frame to create a quiet barrier against cold air. This reduces rattling, lowers heat loss and improves acoustic comfort without altering the visual appearance of the window. For Kensington homeowners who wish to maintain authenticity while enjoying improved comfort this is one of the most effective upgrades available.
Kensington is a busy district with a mixture of residential streets and lively routes such as Kensington High Street and Gloucester Road. Many homes benefit from improved acoustic insulation especially those located near busier areas or beside larger apartment blocks. Secondary glazing provides excellent performance while allowing original sash windows to remain untouched. Installed internally it enhances both warmth and noise reduction while preserving the exterior appearance of the building. For those seeking a permanent integrated upgrade we also create slimline double glazed sash windows which replicate the slim profiles of original joinery while delivering the benefits of modern glazing. These are particularly suited to Kensington’s period properties because they maintain the correct proportions, glazing bar layouts and timber detailing while offering improved insulation.
Wooden doors in Kensington vary widely in style. Many Georgian properties feature classic panelled entrances, larger Victorian townhouses include decorative glazing or carved details and more contemporary homes integrate clean elegant timber designs. A well crafted door enhances both security and kerb appeal. We design and hand build bespoke wooden doors tailored to the architecture of your home. Using sustainable timbers such as Accoya and Red Grandis we create doors that withstand Kensington’s variable climate and long term use. Each door is crafted using mortise and tenon joinery for exceptional strength. We can replicate original designs faithfully or develop new styles that complement your property’s proportions. For existing heritage doors we also provide restoration and refinishing to refresh their appearance while preserving the historic fabric of the building.
Kensington interiors often include high ceilings, decorative cornices, generous rooms and elegant proportions. Homes here range from mansion flats and townhouses to converted apartments shaped by the area’s architectural heritage. Many of these interiors benefit from bespoke joinery designed to enhance practicality while respecting the property’s character. We craft fitted wardrobes, alcove units, kitchen cabinetry, window seats and storage solutions using sustainable hardwoods and finishes selected to suit your interior style. Each piece is made to measure ensuring it fits the space with complete accuracy and blends naturally with the home’s design.
Our approach to joinery in Kensington is guided by sustainability and respect for heritage. We follow a repair first philosophy which preserves original materials wherever possible and reduces unnecessary waste. When new timber is required we choose responsibly sourced hardwoods known for long term performance. All finishes are breathable which allows timber to respond naturally to environmental changes. This ensures long lasting results and protects the character of Kensington’s architectural landscape.
Kensington’s buildings vary greatly in age and construction which means joinery must be customised carefully. Many period homes have thick masonry walls and timber frames that respond differently to temperature changes throughout the year. Apartments in mansion blocks often experience varied humidity levels depending on floor height and exposure. Our understanding of these local conditions allows us to restore and install joinery that accommodates movement while maintaining smooth reliable operation. Every project is tailored so that the windows and doors perform consistently in the long term.
Kensington’s visual identity is shaped by its historic façades, refined details and traditional craftsmanship. Sash windows, wooden doors and timber mouldings play an important role in maintaining architectural continuity. When restoring or creating joinery we match original mouldings, glazing bar patterns, profiles and detailing so the finished result aligns seamlessly with the building’s existing features. Our aim is always to enhance comfort and durability without compromising the heritage that makes Kensington so distinctive.

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. 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.
