When To Repair or Replace Windows?

When deciding between window repair or replace, homeowners often weigh cost, performance, and longevity. This decision becomes clear when factoring in issues like blown double glazing, moisture between panes, and general wear. 

C&L Windows offers trusted solutions, whether it’s advice on repair or replacement, or full-scale new windows, ensuring your home remains comfortable, secure, and energy efficient.

Spotting Blown or Foggy Double Glazing

Perhaps the most common sign that a window needs replacing is blown double glazing, visible as a foggy layer between the panes. This occurs when the seal around the insulated glass unit fails, allowing moisture to enter in between the panes. Once the seal is compromised, any change in temperature can accelerate the seal failure and cause further issues.

If you notice persistent fogging or condensation between panes, you may have heard about resolving the issue with a hair dryer or a temporary ventilation hack. But unfortunately, these fixes only clear the moisture visually. They don’t restore insulation or thermal performance. 

As experts confirm, once the moisture gets in, the only permanent solution is to replace the glass unit, which is often more cost effective than replacing the entire frame. However, if you have any further issues with your windows, it is worth considering a window replacement. 

Costs to Replace vs Repair

The cost of window replacement depends on whether you’re replacing just the glazed glass unit or the entire window. As mentioned previously, glass unit replacements can be significantly cheaper than swapping the entire frame. However, if frames are warped, cracked, or poorly insulated, full window replacement is wiser for long term performance compromises.

Repairing Traditional Window Issues

Before rushing to replace, several common window problems can be easily fixed in some cases. These issues include:

• Fog on the inside of the glass: This typically happens due to high levels of indoor moisture. Increasing ventilation, opening trickle vents or using extractor fans and dehumidifiers are recommended by our experts.

• Water between window panes: This often occurs from seal failure. It requires replacement of the glass unit, not just cleaning or a full window replacement.

• Broken window handles or hinges: These can be adjusted or replaced at an affordable cost. 

• Draughty windows or gaps: Most draughts are due to seal or bead failure, but resealing the windows can quickly restore comfort.

When to Replace Windows Entirely?

There are certain key situations where full window replacement is the best path for your home, as the functionality of your windows will be severely compromised, resulting in issues with energy efficiency, maintenance, security, and durability.  

• Failed glass units and damaged frames: If you are experiencing moisture, rot, deformation, or warping, it compromises the functionality of your windows.

• Poor energy efficiency: If your windows are below the modern energy standards (e.g., U-value above 1.8 W/m²K), investing in A or A+ windows can reduce energy bills.

• Persistent condensation on the inside: This indicates inadequate sealing or insulation, which can often be corrected with replacement.

• Security concerns: Installing modern multi-point locks and reinforced frames improves safety.

• Aesthetic updates: New frames in stylish finishes will revitalise your home. Luckily, our windows are available in over 20 colours and woodgrain foils, and you can view our window styles by checking our recent guide.
