Sash Window Repair, Restoration & Installation in Berkshire

Specialists in Timber Sash Windows

At Kellys Sash Windows, we are proud to offer expert sash window repair, restoration, and installation services across Berkshire. With over 25 years of experience, we have built a reputation for crafting and installing traditional timber sash windows that enhance the beauty and efficiency of period properties. Our skilled craftsmen use a combination of heritage techniques and modern technology to deliver stunning, long-lasting windows that maintain the character of your home while improving insulation and security.

If your wooden sash windows have deteriorated over time, need better energy efficiency, or require a complete replacement, we provide bespoke timber solutions to suit every requirement. We understand the importance of maintaining authenticity, particularly for homes in conservation areas or listed buildings, which is why all our windows are handcrafted to match original designs while meeting modern performance standards.

 

 

Sash Window Repair & Restoration

Sash windows are a key feature in many period properties, but over time, they can suffer from draughts, rot, or broken mechanisms. Our sash window repair and restoration service in Berkshire ensures that your existing windows are carefully restored to full functionality without the need for complete replacement.

Our restoration process includes repairing damaged timber, replacing worn-out sash cords, rebalancing the sashes, and installing draught-proofing to improve insulation. If the glass has become inefficient, we can also install thin double glazing that retains the look of single-pane glass while significantly enhancing energy efficiency. By opting for restoration over replacement, homeowners can preserve the character of their traditional sash windows while benefiting from improved comfort and performance.

Heritage-Approved Double-Glazed Sash Windows

Many homeowners in Berkshire wish to upgrade their sash windows to double-glazed versions, but those in listed buildings or conservation areas must meet strict regulations to ensure that replacements are historically accurate. Our heritage-approved double-glazed sash windows are designed to replicate original designs while discreetly incorporating modern energy-saving technology.

We use sustainably sourced timber to craft elegant yet durable wooden sash windows that retain the charm of period properties. Our double-glazed units significantly reduce heat loss, keeping your home warmer in winter and cooler in summer, while also enhancing soundproofing—an essential feature for properties in busier locations. The improved security features of modern glazing and locking mechanisms also provide homeowners with greater peace of mind.

For properties in conservation areas, we work closely with local authorities to ensure that all window upgrades comply with planning regulations. Our expertise in heritage sash windows means that you can enjoy the benefits of double glazing without compromising on the historic character of your home.

Complete Boxed Sash Window Replacement

In cases where sash window restoration is not viable due to severe deterioration, we offer complete boxed sash window replacements. Unlike partial replacements that retain the existing frame, a complete replacement involves removing the entire window structure and fitting a brand-new, custom-made sash window.

Our replacement timber sash windows are handcrafted to match the original style of your home, ensuring a perfect fit and seamless integration with your property’s aesthetics. Whether your home features Victorian, Georgian, or Edwardian-style windows, we can replicate traditional detailing such as classic mouldings, traditional horns, and pulley-and-cord counterbalance systems.

By choosing complete boxed sash window replacement, homeowners benefit from improved insulation, enhanced durability, and better ease of use, all while maintaining the historic beauty of their property.
