Double glazing is an essential feature in many UK homes, offering energy efficiency, sound insulation, and improved security. However, like all things, it can wear down over time. One common issue homeowners face is failed seals in their double-glazed windows, leading to inefficiencies. But, can double glazing be resealed? The short answer is yes, and resealing can significantly improve your window’s performance. In this guide, we’ll discuss the top signs your double glazing needs resealing and explain how to address the issue.
Signs Your Double Glazing Needs Resealing
1. Condensation Between the Glass Panes
One of the clearest indicators that your double glazing has a failed seal is condensation trapped between the panes. This happens when moisture seeps into the space due to the broken seal, leading to foggy windows that never seem to clear up.
2. Draughts Around the Window
If you notice a cold breeze coming through your windows, even when they’re closed, it’s likely due to a gap in the seal. This can cause a dramatic loss of heat in your home, driving up energy bills as your heating system works overtime to maintain a comfortable temperature.
3. Reduced Sound Insulation
Double glazing not only helps with thermal efficiency but also blocks out noise. If you suddenly start noticing more external noise, it could be a sign that your windows’ seals are failing, compromising their insulating properties.
4. Higher Energy Bills
A rise in your heating costs without a change in usage may indicate that your double glazing is no longer performing as it should. Broken seals lead to heat loss, which can make your home less energy-efficient and cause an unexpected spike in your bills.
5. Visible Gaps or Cracks in the Seal
Sometimes the sealant around the edge of the window can crack or visibly deteriorate. Inspect your windows regularly for any gaps or cracks around the frame – it’s a tell-tale sign that resealing may be needed.
How to Fix Double Glazing Seals
DIY Fixes for Minor Issues
If the seal damage is minimal, there are some temporary fixes you can try. Silicone sealant, available from most DIY stores, can be used to fill small gaps. However, this is not a long-term solution and should only be considered a stop-gap until a professional reseal can be arranged.
Professional Resealing Services
For more serious seal damage, it’s best to consult a professional window repair company, like Cove Glass. We specialise in resealing double glazing, restoring the effectiveness of your windows without needing a full replacement. A professional will remove the old seals, clean the frame, and fit new seals to ensure your windows are airtight once more.
When Resealing Isn’t Enough
In some cases, resealing may not fully restore the function of your windows. If the glass has been damaged, or the frame is in poor condition, replacing the window may be a better long-term solution. At Cove Glass, we offer expert advice on whether resealing is sufficient or if a replacement is the most cost-effective option for your home.
