Garage door rust: How to repair and prevent it

Garage door rust spread over an entire door

Garage door rust doesn’t always mean your door is on its last legs. However, you do want to stop the process in its tracks by beginning to repair garage door rust you see and then implement preventative measures.

Regular maintenance of your garage door will extend its life greatly and reduce the amount of times you’ll experience inconveniences surrounding your door. That’s why everyone with garage doors in Springfield, MO and the surrounding areas should consider a garage door preventative maintenance program.

Here’s what our garage door repair experts have to say about garage door rust.

What causes garage door rust? 

Rust is the naturally occurring reaction when certain metals are exposed to oxygen and water for a long time. Whenever salt is introduced, it speeds up the process because electrons move more easily in salt water than pure water.

Even though most modern garage doors are resistant to rust, older steel garage doors may eventually corrode. Further, rusting is common around the bottom of a garage door if rain, snow, and road salt collects and sits for some time.

So, if you live in an area next to the ocean or if your department of transportation salts the roads when they become iced over, it’s not uncommon for your garage door to rust.

Other factors that cause garage door rust are the quality of metal your door is made of and not regularly cleaning your doors.
