New Malden combines Edwardian charm with suburban comfort. Tree lined avenues, red brick terraces, detached homes and 1930s semis sit alongside more recent developments that reflect the area’s continued growth. Many of these homes still retain their sash windows, wooden doors and traditional joinery details that lend warmth and character to their appearance. Over time though, timber can weather, paint may soften and the movement of older buildings can cause frames to shift slightly. At Traditional Sash Windows and Carpentry, we work throughout New Malden restoring and crafting bespoke joinery that respects the age and architecture of the property while enhancing comfort, efficiency and longevity.
Sash windows are one of the defining features of New Malden’s Edwardian and early twentieth century homes. Their balanced design and slim glazing bars create a soft sense of proportion across the façades. As windows age, cords may fray, sashes can stick or rattle, and timber may begin to deteriorate where moisture has collected. Our sash window restoration process begins with a detailed survey to determine which elements can be preserved. Wherever the original timber remains strong, we retain it to maintain the authentic look of the building. Any weakened sections are carefully removed and replaced with sustainable hardwood, shaped to match the original mouldings. We install new sash cords and rebalance the weights so that the sashes move smoothly and hold securely. The finished window looks period correct but performs as reliably as a modern installation.
New Malden’s homes can experience draughts due to worn seals or small gaps formed through years of expansion and contraction. Our draught proofing service provides a subtle yet effective solution. We fit fine brush seals discreetly inside the window frame, reducing heat loss and eliminating rattles without affecting the appearance of the window. Once complete, homes feel warmer, quieter and more comfortable through all seasons. This is particularly beneficial in larger bay windows common throughout the area, where reducing airflow can make a noticeable difference to indoor comfort and energy efficiency.
Many homeowners in New Malden are choosing to improve insulation and reduce noise from nearby roads and railway lines without losing their property’s traditional charm. Secondary glazing is a great option for this, fitted neatly inside the existing sash frame so that the external appearance remains unchanged. It enhances warmth and sound reduction, making it especially useful for bedrooms or living areas near main routes.
For those seeking integrated performance improvements, we offer slimline double glazed sash windows. These replicate the original style, glazing bar proportions and timber profiles of the existing windows while offering improved thermal insulation and condensation resistance. The result is a window that complements the home’s period character while meeting modern comfort standards.
A wooden door is one of the most characterful features of a property. In New Malden, many homes have elegant panelled front doors with stained or leaded glass, traditional stable doors at side entrances or French doors leading to gardens. At Traditional Sash Windows and Carpentry, we design and build bespoke wooden doors to suit each home. Every door is made using mortise and tenon joinery for long term strength and structural integrity. We use high quality timbers such as Accoya and Red Grandis, which are naturally stable and resistant to weather changes. Each door is finished with breathable protective coatings that allow natural expansion and contraction, helping to prevent cracking or warping. For doors that have historical or sentimental value, we also offer door restoration, including timber repairs, realignment and refinishing.
Homes in New Malden often feature generous rooms, chimney breast alcoves and bay windows, making them perfect for bespoke interior joinery. Whether it’s fitted wardrobes, alcove shelving, window seats, bookcases, kitchen cabinetry or utility storage, our custom made joinery solutions are designed to maximise space while complementing the property’s architecture. Each piece is handcrafted to blend seamlessly with existing features, providing both practicality and elegance. By using sustainable hardwoods and traditional techniques, we create furniture that feels like a natural extension of the home.
We follow a principle of repair before replacement wherever suitable. Retaining original joinery preserves a building’s heritage and reduces waste. When new joinery is required, we use FSC-certified sustainable timber, choosing species that offer excellent stability and longevity. Accoya and Red Grandis are our preferred materials due to their resistance to swelling and shrinking throughout the year. We also finish all of our joinery using breathable, eco-friendly coatings that protect the surface while allowing natural flexibility. This careful approach ensures long term durability and minimal maintenance requirements.
New Malden’s properties range from older homes built on clay soils to newer developments with modern foundations. These variations can influence how joinery behaves over time. Settling and temperature changes can cause subtle movement within frames, so we tailor our work to support the natural behaviour of each building. This attention to local conditions ensures that every sash window and wooden door we restore or install remains stable, smooth and long lasting.
New Malden’s streets are defined by continuity—rows of bay windows, decorative joinery and consistent proportions. When restoring or replicating sash windows, wooden doors or exterior joinery, we carefully match moulding profiles, glazing bar details and frame dimensions to ensure harmony within the streetscape. Our aim is to enhance comfort and performance without altering the architectural features that make these homes so appealing.
If your home in New Malden has sash windows, wooden doors or bespoke joinery that require expert restoration or improvement, we would be delighted to assist. Our team combines traditional craftsmanship with modern precision to create joinery that stands the test of time.

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.
