While cracked window panes are a clear indicator that your windows need replacing, not all danger signs are so obvious.
When your windows are worn, damaged, or in need of upgrading, they cause the heating and cooling systems of your home to go the extra mile.
Here are some unexpected signs that it’s time to replace your window panes, according to two experts.
1. Seal is broken
A broken seal can be a sign that it’s time to repair or replace your window panes, according to David Flax, vice president of operations for Window Genie, a Neighborly company.
“You’ll see humidity and fog appearing on or between the panels,” he says of the main symptom.
Ultimately, this means your electricity bill is likely to go up as your system tries to stabilize the interior environment.
2. Operational problems
If your windows don’t open or close the way they used to, there could be a bigger problem, says Flax.
Sometimes it’s just something like tightening a screw, but other times it may be a sign of a broken window pane, and in which case you need replacement,” he said.
3. Increased cooling costs
Are you spending more money to keep your home at a comfortable temperature? Brad Roberson, president of Glass Doctor, says your window pane may have lost some of its efficiency.
Single-panel and dual-panel units that wear out are prone to leaks.
4. There is an incoming wind
It may seem like an obvious sign, but Flax says it’s actually hard to detect wind.
“You may not feel a strong wind. On the other hand, some areas of your home may feel cooler,” he says.
If this happens frequently near windows and there is no ventilation nearby, it’s time to investigate to replace it.
5. Condensation or buildup of water
Unfortunately, water appearing between your windows can only be caused by one thing, according to Flax: a broken seal that is no longer airtight.
Roberson agrees, adding that fog or condensation between the panels could indicate seal failure, which could allow moisture into your space.
6. Cold window glass
When your windows are cold to the touch, your home doesn’t efficiently retain hot and cold air, notes Roberson.
“For more efficient heating and cooling and a more comfortable home, you need windows that offer better insulation properties.”
If what’s happening outside your window seems as though it’s happening inside your home, you may have a panel problem, notes Flax.
