One of the most common questions we hear from homeowners is how much it costs to restore traditional sash windows. Many people assume that once a sash window becomes difficult to open, draughty or damaged, replacement is the only option.
In reality, restoring the original window is often far more cost-effective while preserving the character of the property.
At Brown’s Sash Windows Restorations, we regularly restore sash windows across Retford, Nottinghamshire and the surrounding areas, helping homeowners improve comfort while maintaining original timber windows.
What Affects the Cost of Sash Window Restoration?
The cost of restoring sash windows can vary depending on several factors.
Condition of the Window
The overall condition of the timber plays a major role in the amount of work required. Windows with minor issues such as sticking sashes or worn cords will generally require less work than windows with extensive timber decay.
Number of Windows
Many restoration projects involve several windows within the property. When multiple windows are restored at the same time, the cost per window is often reduced.
Timber Repairs
Older windows sometimes develop areas of rot, particularly around sills or lower frame sections. These damaged areas can usually be repaired using specialist timber repair systems, allowing the original window to be preserved.
Draught Proofing
Many homeowners choose to add draught proofing during restoration. This helps reduce cold air entering the property and can significantly improve comfort.
Double Glazing Upgrades
In some cases, sash windows can be upgraded with slimline double glazing. This improves insulation while maintaining the traditional appearance of the window.
Why Restoration Is Often Cheaper Than Replacement
Replacing sash windows can be expensive and may alter the appearance of a period property. Restoration allows the original timber windows to be repaired, serviced and improved without losing their historic character.
Benefits of restoration include:
-
preserving original features
-
lower cost compared with full replacement
-
improved window operation
-
better energy efficiency with draught proofing
With the right care, restored sash windows can continue to perform well for many decades.
