Do my windows need resealing?
Over time, windows may benefit from being resealed or replaced. If you notice the following, you should consider resealing your window:
- Condensation on an internal pane of glass
- Draughts from the window
- Noticeable wear, tear or gaps around the seal
There are many factors that contribute to a damaged window seal. Something as simple as temperature can slowly affect the seal, as windows naturally expand and contract to adapt to this change. Eventually, this can have a damaging effect, as can using strong or abrasive cleaning products on the window unit.
If you've noticed condensation on an internal pane of glass, the sealed unit may have sprung a leak. If it has, the damaged seal is allowing air to enter and inert gas within the unit to escape. This may not be very noticeable to start with, so make sure you check carefully. It will become progressively worse as moisture begins to build up inside.
The efficiency of a window will be compromised if its seal is not working correctly. Insufficient seals allow heat to escape from your home, which can cost you money. If resealing a window doesn't solve the issue, or if your windows are very old and worn, you may benefit from replacing the entire window with new double glazing instead.
Draughty windows can also be cured by replacing or resealing a window. Find out more about how to cure a draughty window here.
