While most quality sliding patio doors have relatively long service lives, they can fall to a variety of maladies. Whereas some sliding patio door problems can be fixed with only a few tools and a small amount of time, others are so serious that they merit complete replacement. Especially if your sliding patio door setup is relatively old, don't ignore these three signs that you should completely replace it.
The Doors' Bottom Tracks Have Warped And Ceased To Go In Straight Lines
A sliding patio door depends on the integrity of its bottom track to slide smoothly across the indentation on the floor. If this track ever gets so warped by the elements or by flood water that it can't be pushed across the floor without putting the whole door at risk of breaking, your whole patio door setup becomes almost useless.
Luckily, it takes a lot of warping to reach such a serious point. As long as you can get the track across the floor indentation with a moderately determined push, there's no need to worry about it.
Edges Of Glass Panes Are No Longer Securely Attached To Frames
When you first get a sliding patio door, you shouldn't be able to move the edges of its glass pane at all. The glue in between the door frame's wooden, plastic, or metal panels should be much too strong for that.
But a long period of use and exposure to the elements will slowly weaken this glue over time. If the bond gets so weak that you can easily shake the glass pane from more than one side, it's time to get a new door that's more structurally sound.
If you act quickly, you may be able to salvage the glass pane and have a professional work it into a replacement door. On the other hand, if you ignore the problem, the pane could come loose and shatter at an unexpected moment.
Lock Mechanism Is Completely Dominated By Rust
It shouldn't take more than a few seconds to close and lock your sliding patio door setup. If you're hindered because the rust on the lock mechanism is making it very hard to line the two connecting parts up, it's time to consider getting a new door setup that won't have these issues.
If rust is forming on a place where it's very visible like the exterior of a lock mechanism, there's a good chance that rust is also a huge problem in your patio doors' internal and more hidden components.
