How can I tell if my double glazing needs replacing?
You can tell if your double glazing needs replacing by looking for the following signs:
1. Condensation Between Panes
If moisture or fog appears between the two glass panes, it means the seal has failed, allowing air and moisture inside. This reduces insulation and efficiency.
2. Drafts and Cold Spots
If you feel cold air coming through or near the window frame, the seals may have deteriorated, reducing thermal efficiency.
3. Increased Energy Bills
If your heating costs have risen, your double glazing may no longer be insulating properly, allowing heat to escape.
4. Difficulty Opening or Closing Windows
Frames can warp over time, causing stiffness or difficulty locking, which compromises security and insulation.
5. Visible Damage or Cracks
Cracks in the glass or damaged frames indicate structural weakness, reducing security and efficiency.
6. Noise Leakage
If outside noise seems louder than before, the insulating properties may have weakened, suggesting a need for replacement.
7. Faded Furniture and Carpets
Old double glazing may not block UV rays effectively, causing furniture and carpets to fade over time.
If you notice any of these signs, it might be time to consider replacing your double glazing to improve insulation, security, and energy efficiency.
If you believe you have double glazing failure please follow these steps to address the issue:
1. Assess the Extent of the Problem
- Condensation Between Panes → Seal failure, meaning the unit is no longer airtight.
- Drafts or Cold Air → Could be due to worn seals or damaged frames.
- Cracked or Damaged Glass → Reduces insulation and security.
2. Check if It’s Under Warranty
- Many double glazing units come with warranties (often 10–20 years). If yours is still covered, contact the installer or manufacturer for a repair or replacement.
3. Consider Repairs or Replacements
- Seal Replacement → If only the seal is broken, some companies offer re-sealing services. However, this is usually a temporary fix.
- Glass Unit Replacement → In some cases, you can replace just the glass unit without changing the entire window frame.
- Full Window Replacement → If the frame is also damaged or very old, a complete replacement may be necessary.
4. Improve Temporary Insulation
While waiting for a repair or replacement:
- Use temporary sealants or weatherstripping to reduce drafts.
- Apply plastic film insulation over the window to retain heat.
5. Get Professional Advice
- Contact a double glazing specialist for an inspection and quote.
- Compare repair vs. replacement costs to determine the best option.
