Why Resealing Double Glazed Windows Matters
Double glazed windows are known for their energy efficiency, noise reduction, and thermal insulation. However, over time, the seals that keep your window units airtight can begin to deteriorate. For UK homeowners, this might mean a less comfortable living environment and higher heating bills. Catching the signs early can prevent costly replacements and extend the lifespan of your windows.
How to Spot Seal Failure
Here are five key indicators that your double glazed windows might need resealing:
1. Condensation Between the Panes
One of the most telling signs is moisture or fog forming between the glass panes. This means the vacuum seal has failed and moisture is entering the space that should be airtight.
2. Draughts Near the Frame
If you feel cold air coming in around the edges, even when the window is shut fully, the seal around the edge could be worn or damaged. Draughts make it harder to keep your home warm and comfortable.
3. Increased Energy Bills
Failing seals mean your home is not as energy-efficient, resulting in rising heating costs. This is particularly noticeable during chilly UK winters where insulation is critical.
4. Distorted or Hazy View
A cloudy, misty appearance through your window may indicate condensed mineral deposits inside the unit. This distorts the transparency of the glass and indicates that the insulating layer is compromised.
5. Cracked or Damaged Sealant Around the Edges
A visual inspection might reveal cracked or peeling sealant around the frame. This protective material keeps moisture out but can deteriorate over time due to sun exposure or temperature fluctuations.
What You Can Do Next
While minor condensation or draughts can seem like small problems, they’re often indicators of bigger issues developing. Taking early action can prevent more serious (and more expensive) outcomes. If you’re unsure whether your windows need resealing or full replacement, a professional inspection is the best move.
