Resealing double-glazed windows can be helpful if you notice:
- Condensation on the inside of the glass
- Draughts from the window
- Visible wear, tear, or gaps in the seal
Several factors can damage a window seal. Even something as simple as temperature changes can harm the seal over time. Windows expand and contract with temperature changes, which can cause damage. Using strong or abrasive cleaning products on the window can also be damaging.
If you see condensation on the inside of the glass, the sealed unit may have a leak. It may not be very noticeable at first, so make sure to check carefully. It will get worse as moisture builds up inside. This allows air to enter and the inert gas inside to escape.
If this happens, you need to replace the sealed unit. If you have windows from us, you will have a sealed unit guarantee. It lasts 10-15 years after installation, depending on the window material.
Can you reseal windows?
It is possible to reseal windows, especially if there are gaps between the window and the siding. But, it is better to ask a professional for help, rather than doing it yourself.
If resealing the window doesn’t fix the issue, then then other option is replacing it.
