Our Aims

At Traditional Sash Windows and Carpentry, we proudly serve the communities of Kent and London. Our core value is to stick to traditional methods while using modern technology. We will never recommend switching to uPVC in any of our quotes. Most modern sash window alternatives are not suitable for old buildings and do not stand the test of time like traditional sash windows.

Traditional sash windows, especially those made from high-quality timber and properly maintained, can last for well over a century.

Many Georgian and Victorian sash windows have already proven their longevity by remaining functional for 150 years or more. With regular maintenance, such as repainting, sealing, and occasional repairs, these windows can continue to function beautifully and add historic charm to a property. On the other hand, uPVC windows typically have a lifespan of about 20 to 35 years.

While uPVC windows require less maintenance than traditional timber sash windows, they are more susceptible to discoloration, warping, and general wear over time. Once they reach the end of their lifespan, they usually need to be replaced entirely, as they are difficult to repair.

We will always try to draught proof,  repair, restore or replace windows to replicas of the ones being worked on.  With any new windows, we can either match the old designs or customise them to your liking. We have a history of working with both commercial, private and listed buildings and will do up upmost to provide you with the best service possible.

If you’re on the hunt for replacement sash windows that perfectly replicate traditional style but deliver modern performance look no further. At Traditional sash windows, we supply premium timber sliding sash windows that complement a range of properties. So, no matter whether you live in a Victorian townhouse, Edwardian cottage or Georgian terrace you’re sure to find a sash window to match your home’s unique character.

Detailed services

Sash windows, also known as sash and case windows, are a classic feature of many historical and period properties. While they add charm and aesthetic value, they often require maintenance to ensure they function efficiently and provide adequate insulation. Draft proofing and overhauling sash windows are essential tasks to preserve their functionality, enhance energy efficiency, and extend their lifespan. Sash windows are a British hallmark of many historical and period properties, providing an elegant and traditional appearance. However, over time, these windows may suffer from wear and tear, requiring either repair or replacement to maintain their functionality and aesthetic appeal.

Overhaul and Draught proofing

Draft proofing and overhauling sash windows are essential processes that can significantly enhance energy efficiency, reduce energy bills, and improve indoor comfort. These methods focus on sealing gaps and cracks around sash windows to prevent cold air from entering and warm air from escaping, while restoring the structural integrity and functionality of the windows.

The draft proofing process begins with a thorough assessment and preparation. First, a detailed inspection is conducted to identify any gaps, cracks, and areas prone to drafts. Once these areas are identified, the window frames and sashes are cleaned to ensure a smooth surface for applying seals.

Sealing gaps involves several steps. High-quality weather stripping is installed around the window sashes, filling gaps and preventing drafts. Worn-out sash cords are replaced to ensure smooth operation and proper sealing. Additionally, a durable, flexible sealant is applied around the window frame to seal any remaining gaps. For improved insulation, homeowners may consider upgrading to double glazing or installing secondary glazing, which adds an additional layer of insulation if replacing the original glass is not feasible.

Overhauling sash windows involves a comprehensive restoration process that includes repairing, refurbishing, and enhancing the window's structural integrity and functionality. This process starts with the careful removal of the upper and lower sashes from the frame, followed by the detachment of the sash cords and removal of the counterweights. Next, any wood rot or damage is addressed through woodwork repair, and damaged sections of the sash and frame are replaced or repaired.

During reassembly, new or sash cords and weights are reattached to ensure smooth operation, and the upper and lower sashes are reinstalled, ensuring they are properly aligned and balanced.

Final adjustments are made to ensure the sashes are balanced and can open and close effortlessly. Modern security features, such as locks and restrictors, are installed to enhance safety.

Draft proofing and overhauling sash windows offer numerous benefits. These processes significantly reduce heat loss and improve thermal insulation, leading to lower energy bills. By eliminating drafts, they provide a more comfortable indoor environment and improve sound insulation, reducing external noise penetration. Moreover, they maintain the aesthetic and historical integrity of period properties, which helps preserve their historical value. Well maintained sash windows also enhance the overall value of the property, making these processes a worthwhile investment.

Repair or replacement of Sash Windows

Sash window repair involves fixing specific issues to restore the window's functionality and appearance without the need for a complete replacement. This process is ideal for preserving the original character of the property while addressing problems such as rot, broken panes, and faulty mechanisms.

The first step in sash window repair involves a thorough assessment and diagnosis. During this inspection, damage such as wood rot, broken glass, and malfunctioning sash cords are identified. Understanding the root cause of these issues helps in planning the appropriate repairs.

Woodwork repairs are then conducted, where any rotten wood is removed and treated with a wood preservative. High-quality resin is used to repair minor cracks and holes, which are then sanded down for a smooth finish.

Broken glass panes are carefully removed to avoid damaging the surrounding woodwork, and new glass panes are installed using glazing putty or modern glazing beads for a secure and weatherproof seal.

Mechanism repairs are also essential. Worn or broken sash cords are replaced to ensure the smooth operation of the sashes. Pulleys and counterweights are inspected and adjusted to ensure the sashes are balanced and easy to open and close.

The final steps involve finishing the windows. All repaired areas are sanded down and primed/undercoated, leaving them ready for the customer to have them decorated.

Sash window replacement, on the other hand, involves removing the old windows and installing new ones. This process is necessary when the existing windows are beyond repair or when homeowners wish to upgrade to more energy efficient or modern designs while retaining the traditional sash appearance.

The process starts with an initial consultation and measurement, where a sash window specialist discusses options, materials, and design preferences with the homeowner. Precise measurements of the existing window openings are taken to ensure the new windows fit perfectly.

The next step is the careful removal of the old sashes, frames, and any remaining glazing, ensuring minimal damage to the surrounding structure. The window opening is then cleaned thoroughly to remove dust and debris, and any necessary adjustments to the frame or opening are made to ensure a secure fit for the new window.

The new sash window frame is installed, ensuring it is level and securely fixed in place, followed by fitting the new sashes into the frame to ensure smooth operation and proper alignment. Final adjustments include applying weather stripping and sealant around the frame to prevent drafts and enhance insulation. The new window is then painted or varnished to match the property's aesthetics and protect the wood from the elements.

Both sash window repair and replacement offer significant benefits. They improve thermal insulation, reducing energy costs, and maintain or enhance the traditional charm and character of the property. Additionally, well-maintained or upgraded sash windows add value to the property, ensure smooth operation, improve security features, and extend the lifespan of the windows, providing long-term benefits.

Wooden Door Repair

Repairing a wooden door involves addressing specific issues to restore its functionality and appearance without the need for a complete replacement. This process is ideal for addressing problems such as wood rot, cracks, and faulty hardware.

The repair process typically begins with a thorough assessment and diagnosis. During inspection, any signs of wood rot, cracks, or damage to the door frame, panels, or hardware are identified. Once the issues are pinpointed, appropriate repair techniques are employed. For wood rot, affected areas are carefully removed and treated with wood preservatives to prevent further deterioration.

Cracks and holes in the wood are filled with high-quality wood filler, which is then sanded down to create a smooth surface. Damaged hardware, such as hinges or locks, may need to be repaired or replaced to ensure proper functionality and security.

Sometimes, replacing a wooden door is necessary when repairs are no longer feasible or when upgrading to a new design or style. This process involves removing the old door and installing a new one that meets modern standards of energy efficiency, security, and aesthetics.

The replacement process typically begins with an initial consultation and measurement. A door specialist discusses options such as materials, designs, and hardware preferences with the homeowner. Precise measurements of the door frame and opening are taken to ensure the new door fits perfectly.

Once the consultation and measurements are complete, the old door is carefully removed, including any hardware and weather stripping. The door opening is then cleaned and prepared for the new door installation. This may involve making adjustments to the frame or threshold to accommodate the new door's dimensions and ensure a secure fit.

Next, the new wooden door is installed. The frame is checked for levelness, and the door is securely fixed in place. Proper insulation and sealing techniques, such as weather stripping and caulking, are applied around the door frame to enhance energy efficiency and weather resistance.

Finally, the new door is finished with paint or varnish to match the homeowner's preferences and protect the wood from the elements. This step not only enhances the door's appearance but also ensures its longevity and performance over time.

Wooden Door Repair and Replacement offer significant benefits to homeowners, such as:

Enhanced Functionality: Repairing specific issues with a door can restore smooth operation and functionality, while a full replacement allows for upgrading to modern hardware and can add advanced security features.

Aesthetic Appeal: Both processes can enhance the curb appeal and aesthetic value of the home, maintaining or updating its overall look.

Energy Efficiency: Replacement doors often come with improved insulation properties, reducing energy costs over time.

Increased Property Value: Well-maintained or upgraded doors can increase the resale value of the home.

Longevity: Properly repaired or replaced doors can last for many years, providing durability and peace of mind.

Double Glazing

Double glazed sash windows offer modern benefits while retaining the classic charm of traditional sash designs. Here’s a comprehensive look at both the repair and replacement processes, along with their respective benefits:

Repairing double glazed sash windows involves addressing specific issues to restore their functionality and energy efficiency. The process begins with a thorough assessment and diagnosis. Inspection of the windows for any signs of damage, such as failed seals, drafts, or condensation between the glass panes. Identifying these issues helps in planning the appropriate repairs.

Common repairs include:

Glass Replacement: If there’s condensation between the glass panes (indicating seal failure), the affected glass unit may need to be replaced to restore clarity and insulation.

Hardware Adjustment: Ensure smooth operation by adjusting or replacing hardware such as sash cords, pulleys, or balances.

After repairs, the windows are resealed and refinished to enhance their appearance and durability.

Replacement becomes necessary when existing windows are beyond repair or when homeowners desire enhanced energy efficiency and performance. The process typically includes:

Consultation and Measurement: Discuss options with a window specialist, including materials, designs, and energy-efficient features. Accurate measurements are crucial for custom fit replacements.

Removal of Old Windows: Carefully remove existing sashes, frames, and any remaining glazing while minimizing disruption to the surrounding structure.

Preparation of Openings: Clean and prepare the window openings, making any necessary adjustments to accommodate the new windows.

Installation of New Windows: Install the double glazed sash windows, ensuring they are properly insulated and sealed to prevent drafts and improve energy efficiency.

Finishing Touches: Apply weather stripping and sealant around the frames, and finish with paint or stain to match the home’s aesthetic.

Both repairing and replacing double glazed sash windows offer several benefits:

Improved Energy Efficiency: Double glazing provides better insulation, reducing heat loss in winter and keeping interiors cooler in summer. This can lead to lower energy bills.

Enhanced Comfort: Reduced drafts and improved insulation create a more comfortable indoor environment year-round.

Noise Reduction: Double glazing helps minimize external noise, enhancing the tranquillity of your home.

Aesthetic Appeal: Maintain or enhance the traditional charm of sash windows while benefiting from modern energy-efficient technology.

Increased Property Value: Well-maintained or upgraded windows can enhance the overall value and appeal of your property.

Long-Term Savings: Energy-efficient windows can offer long-term savings on heating and cooling costs, offsetting the initial investment.

In conclusion, whether repairing existing double glazed sash windows or opting for replacement, homeowners can enjoy improved energy efficiency, enhanced comfort, and aesthetic benefits while preserving the architectural integrity of their property. These investments contribute to a more sustainable and comfortable living environment.
