    As specialists when it comes to sash window repair, maintenance and restoration, we are able to offer a diverse range of solutions to the problems associated with poorly maintained windows. Our draught sealing system, for example, can effectively breathe new life into your windows and doors. Our restoration techniques have been proven to dramatically improve both door and window performance at a fraction of the cost that replacement would require.

    Did you know that draught sealing only has a VAT rating of 5%? Raising the heat and fuel efficiency of your home is something that you can’t afford to miss out on!

    For many, these historical features are probably the reason why they decided to purchase the property in the first place, so their interest in retaining the look of it will be a vested one – after all, with good repair and restoration, the property will grow in value if ever the owner wishes to sell. Other buildings, especially ones designated for public use, will be listed and therefore, the original character must be retained by law.


    Our refurbishment services can offer a diverse range of advantages to homeowners, including:

    • No more draughts
    • No more rattling
    • Improved soundproofing
    • Improved insulation and heat-retention
    • Drastically reduced dirt and dust
    • Smoothly-operating sash windows and doors.
    • Extended window life
    • Improved security


    The gaps around a typical sash window can add up to the equivalent of a hole around 150 sq mm, or as much as 6 inches. Without effective and professional draught sealing, dust, dirt, the wind and external noises can all flood into your home. Similarly, your home’s heating can filter out through the hole, leaving you feeling uncomfortable, cold, and meaning that you waste money on your heating and fuel consumption.

    As we’re carrying out a sash window restoration draught sealing strategy, we can also take the time to repair and damaged parts of your sash window. Whether it is the timber, the glazing, the locks or the associated ironmongery, we will be able to restore your windows and doors to their former glory.

    As added insurance, our refurbishments all come with a 2-year guarantee. When you choose Kellys’ sash window restoration, you can be assured that you will receive only the very best in professional service. We offer our services across London, Reading and all across the M3/M4 corridor, and we never compromise on service and quality.


    If your current sash windows are single-glazed, cold and are the source of draughts and external noises, then you cannot afford to miss out on the professional service offered by our professional team. Depending on your main focus, we can offer a range of different glazing alternatives to ensure that you enjoy the very best results from your double-glazed sash windows.

    • Reduced Heat Loss – In all of our double-glazed units, we now fit heat-reflective glass as standard.
    • Safety And Security – We can fit laminated and reinforced glass for improved security against external threats.
    • Soundproofing – If external noise is a problem that you are forced to deal with, we can help you. We have a range of acoustic glass, for use in either single or double-glazing applications.
    • Fadeguard – If the position of your window is causing your furniture, fabrics or pictures to fade, then we can provide a solution. Our Fadeguard glass is a kind of laminate glass which excludes almost all ultra-violet rays.
    • Specialist Glasses – We are also experienced in the installation of patterned or etched glass, as well as unique handmade glass, for use in listed buildings or upon request.

    Sash Windows are extremely practical and attractive features which remain popular amongst homeowners and landlords across the country

    Therefore, it can really be a devastating blow when sash windows become damaged and require either repairing or replacing to return the property in question to its former glory. Fortunately, we are able to offer high-quality sash window replacement services, in addition to our professional repair options.


    Completely new windows and doors can really reinvigorate your home, improving both kerb appeal and overall value; this can be extremely valuable when it comes to attempting to sell your property, or to ensure that it appeals to potential tenants.

    Aside from these aesthetic benefits, sash window replacement can offer practical advantages as well. New windows and doors, for example, will be much better insulators; this means that they can make your home warmer in the winter, and reduce the amount of wasted energy, whilst also decreasing the amount and strength of draughts.

    If you aren’t already making the most of it, then double-glazing can help to cut your energy bills as well. Upgrading to a double-glazed model will offer other benefits, including improved security and reducing traffic or external noise.


    Of course, it is cheaper and more environmentally-friendly to restore an existing window than it is to replace it, particularly in the short-term. Also, if you live in a period property, then keeping the original windows and doors offers great benefits, particularly aesthetically.

    Here at Kellys Sash Windows, we are firm believers in restoration over replacement, and our experience allows us to repair many sash doors and windows where others have given up on them. Our professional team will always offer you the very best advice on whether to restore or replace your windows and doors.

    In the event of sash window replacement, we are able to provide a range of windows and doors in a variety of materials, including hardwood and softwood. All replacement windows that we provide are subject to the highest standards and building regulations.
