Window repair cost in the UK refers to the total expense required to restore damaged, malfunctioning, or deteriorated window components, ranging from simple sealant fixes to full-frame refurbishments. Windows are critical to the structural integrity, thermal regulation, and security of a home, and degradation due to weathering, accidental breakage, or aging frames can lead to energy inefficiencies and safety concerns. According to Checkatrade’s 2025 data, window repairs in the UK typically range from £25 for minor fixes such as draught-proofing or seal replacements to £1,500 or more for complex repairs involving sash cord restoration, broken glazing, or structural frame issues.
“Timely window repairs not only prevent heat loss but also help homeowners avoid costly full replacements,” says Mark Fenwick, glazing specialist at the UK Property Maintenance Association. The cost varies significantly by window type—such as uPVC, timber sash, aluminum, or double-glazed units—and by the nature and extent of the problem. For instance, foggy double glazing due to broken seals may cost around £70–£120 per pane, while wooden frame rot repair can climb beyond £300 per window, depending on the depth of the decay.
This cost guide offers a clear framework for assessing potential expenses based on window material, damage severity, and labour complexity. Whether you’re seeking affordable window repairs in the UK or evaluating whether to repair versus replace, this 2025 pricing breakdown provides essential insights to help you plan efficiently and preserve your property’s value.

Factors Affecting Window Repair Costs
The cost of fixing your window depends on several factors:
1. Type of Window
Generally, single pane windows – fixed windows, hopper windows, casement windows, skylight windows – are more affordable than double frame windows.
Double-pane windows are categorized under single-hung, double hung, and storm windows. Bay and arched windows are considered triple-pane windows. Sash windows refer to traditional windows that may require the replacement of cords, frames, or glass.
Window repair cost can start as low as £25, but for more complex pane issues, it can rise to £500 or more. If you’re considering new installations or replacement options, we also supply and install aluminium windows suitable for all property types.
2. Number of Windows Needing Repair
It is simple to understand, the more windows you need to fix, the higher the total cost becomes. Some repair specialists may offer bulk discount rates, but it entirely depends on the business.
3. Extent of Damage and Repairs Needed
The less extensive the damage, the less expensive it will be. Things like major cracks and the need for sealant replacement are very affordable. However, issues more serious like broken seals, shattered double-glazing, condensation buildup inside the panes, and rotten wood frames will be much more costly.
4. Window Accessibility
If the window is placed in remote areas that are hard to reach like attics or higher floors, specialists may charge extra. In such cases, the window repair cost can increase substantially due to the need for ladders, scaffolding, or additional safety equipment.
5. Availability of Materials
Replacing vintage or custom windows can be more costly due to limited availability of parts, while newer double glazed windows parts are easier to source.
6. Labour Costs
Professional window repair specialists tend to charge around £25-£35 per hour. However, if the solution needed is more complicated, the repairs will be more expensive. For affordable and efficient installations, consider our trusted upvc window installers for modern and traditional homes.
How to Dry Out Blown or Misted Windows
Blown or misted windows are often caused by failed seals allowing moisture inside the double glazing. Solutions include:
- Professional repair or glass replacement (misted window repair cost £70 – £250).
- Using repair kits for temporary fixes.
- Full window replacement if damage is extensive.
Should You Repair or Replace Your Window?
If your window has minor fractures, leaks, or seal damage, the window repair cost is often lower than full replacement, making it the most cost-effective option. However, if the window is outdated, significantly damaged, or lacks energy efficiency, investing in a replacement window may be the better long-term solution.
Additionally, ensuring your windows are properly sealed can improve energy efficiency and reduce heat loss. According to the UK Green Building Council, using quality draught sealers can help prevent heat loss and enhance energy efficiency in homes.
