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.
