If you’re looking to replace windows, but aren’t sure if you need to invest in new windows, there are a few telltale signs that will let you know it’s time. Here are five ways to tell if your windows or doors could use replacement.

1) Rotted wood and mold

Old windows can be a breeding ground for mold and rot. They might not necessarily be rotting, but they could have frames or sills that have been damaged by water or general wear and tear over the years. If you notice any discoloration of the wood on your windows or walls surrounding them, this is a sign that something isn’t right. In addition to being unsightly rot puts your home at risk of water damage as well as bugs and rodents.

2) Drafts around windows

The windows in your home shouldn’t be drafty unless it is absolutely necessary to replace them. Drafts can mean that there’s a problem with how they fit against the window sill or siding, they may not be sealed properly.

3) Broken seals

This can happen for a number of reasons including but not limited to: broken seals on windows and doors, lack of caulk between them and walls, cracked windows, and even faulty locks. When you notice any problems like this, it’s time for replacement windows. Not only do these kinds of gaps let drafts in they also allow for moisture to get in.

4) Cracks or chips

In addition to drafts, chipped windows can also lead to water damage and rot as well as a safety hazard. If they have cracks or chips this means they’re not holding up the way they should be and you need new windows.

5) Damaged screens

Window screens can become damaged over time from wear and tear as well as exposure to the elements. When their screen is broken it can lead animals, bugs, and snakes inside your home. This kind of problem could also lead to damaged windows which you’ll hopefully notice before it’s too late.

So, how often should you replace your windows? It all comes down to whenever you actually need it to be replaced. It’s recommended to constantly pay attention to the signs that your windows and doors are aging.
