Patio doors are so important to our homes. Doors are more than just a passage that leads inside and out, they keep out uninvited guests or pests, they protect your home from rain, heat, and snow, they bring in light to illuminate your home, and they extend your living space to the outdoors. Every patio door eventually shows signs of wear and tear, and it’s important to know when it’s time for door replacement! Below are six signs it’s time to replace your old patio doors and upgrade to something new!



Are your patio doors broken and beyond repair? Is the door discolored, scratched, and incapable of cleaning up? If your patio doors require a lot of work and money to fix, you are better off replacing them with new door systems. If the locking mechanism is broken or the door isn’t sealing and allowing water penetration, it’s possible these can be fixed but be sure to consider putting money towards a total door replacement instead because it will provide reassurance knowing that your new door is in working order.

Difficult to Use

If your door is no longer functioning properly or it’s difficult to use, it could be time for replacement.  After a thorough check that no easy repairs will fix your door functionality, you should consider installing new patio doors. An improperly functioning or non-functioning door is more than frustrating, it’s a safety hazard that could put lives in danger in the event of a fire, storm, home intrusion, and other emergencies.

Lack of Light

If you feel like your home is very dark and lacks natural light, this is a good time to consider replacing your patio doors and/or windows and creating a larger opening to connect your home to the outdoors and allow plenty of natural light to illuminate your living space. With a large accordion door system, you can eliminate walls and replace them with folding glass that will make your space feel open and bright.


Sometimes homeowners replace all the windows in their home but neglect the doors. Mismatching doors and windows can look tacky and unappealing, and it’s for this reason you might consider upgrading your patio doors to match the rest of your doors and windows.

Energy Efficiency

If your patio doors are a few decades old, it’s likely that they don’t meet the current energy efficiency standards. Energy efficient doors keep your home cooler in the summer and warmer in the winter, because they prevent air from escaping your home. Non-energy efficient doors are a great excuse to upgrade to a large folding door system that has excellent energy ratings.

Not Maximizing Space

If your current patio doors are in an awkward location that doesn’t make sense, and they’re not maximizing your living space to it’s full potential, it might be time to consider door replacement. Large folding and sliding door systems can connect your home to the outdoors and create a seamless transition from inside to outside. With Bi-Fold or Multi-Slide Doors, you can maximize your living space and extend it into the backyard deck or patio area.
