You can’t replicate the character of historic homes. Sash windows are among the most iconic features of Georgian, Victorian, and Edwardian homes, and as they start to age, the only question is: what should be done next?
Sash window restoration is now the favourite option for period property owners throughout the UK. Preservation does not mean destruction or substitution of original timber frames to fit something that doesn’t really match, but rather restoration of what is there in full working order, and the spirit of the property is maintained. In this guide, you’ll find out what it entails and why historic homes are best suited to this method.
What Is Sash Window Restoration?
The restoration of sash windows involves repairing and refurbishing an original sash window to good working order without replacing the frame.
Most of the work involves the following:
- Replacement of broken sash cords
- The repair of stiff parts
- The solution of localised rot in timber
- The re-glazing is required
- The installation of draught-proofing
- The refinement of the frame.
Ultimately, the idea behind sash window restoration services is to get the window to perform as it did at the time of initial installation. If a sash window has been restored correctly with good-quality draught-proofing, it will hold up better in almost every respect than an old, unsealed original sash window. The cost of sash window repairs can range from repairing a single window to repairing all the windows throughout a building.
Common Problems Found in Historic Sash Windows
With an older sash window, you’re likely facing a common set of problems.
Broken sash cord
These are some of the most common ones, including broken or frayed sash cords. They link the sash to the counterweights within the box frame and, when broken, make the window hard to handle. These are often replaced in any restoration.
Stiff painted windows
Another common issue is stiff or painted shut windows. Prepares sashes for binding in the frame after years of improper preparation and repainting. A competent restorer will adeptly remove the sash without harming adjacent wood.
Presence of draughts
The presence of draughts in older properties is a major issue. Air and heat seep through gaps between the sash and frame, impacting comfort and energy costs. Over the years, localised timber rot may occur in moisture-exposed areas, especially at the bottom rail. If the rot is contained, it can be cut out and set right without destroying the rest of the original frame. That’s why you need traditional sash window restoration for all your windows in period properties.
The Sash Window Restoration Process
From the moment work begins, a specialist will conduct a detailed evaluation of every window and provide a detailed estimate before starting work.
- Care is taken in removing sashes to allow access to the internal box mechanism.
- Old cords are replaced, counterweights are checked, and the reung and the timber are checked for areas in need of repair.
- The frame and sashes are then wiped back, cleaned, and refinished.
- Gaps that cause heat loss are sealed with draught-proofing.
- Sashes are rehung, balanced, and tested for smooth action.
Benefits of Sash Window Restoration
There are definite benefits of restoring sash windows. The best is to retain the essence of a period house. It is difficult to replicate the look and feel of timber sash windows when replacing them with modern windows.
Restoration is also a more sustainable alternative. The benefits of retaining old timber rather than making new frames make for better environmental outcomes, while well-maintained timber sash windows will last well over 100 years.
The addition of draught proofing makes a huge improvement in energy efficiency. If a sash window is installed correctly, it will substantially reduce outside noise and heat loss.
Sash Window Restoration Cost
The price varies depending on the number of windows, the condition of the existing frames, and the extent of work required. Replacing a window that requires cord replacement, draught-proofing, and repainting is less expensive than replacing a window with extensive rot that requires timber repairs and a complete overhaul.
A specialist survey will create a written quote and let any household know precisely what they are acquiring before they commit. Wooden sash window restoration often offers the same functional alternative windows at a reduced total cost and retains the original frame.
