Just like every other functioning part of your home, the windows and doors have a lifespan in which they are still doing their job. Here is your basic checklist:
- Feeling a breeze through your windows on a windy day or a draft on cold days
- Noticing fog on the glass of your windows or doors
- Struggling to open your windows
If you neglect to replace your windows and doors when you notice these signs, you actually lose money in the long run by asking your heating and cooling systems to overcompensate.
