Your garage door works hard every day. Learn the safe, simple checks Knoxville homeowners can do to catch problems early—before they become costly or dangerous. Know when to stop and call a licensed pro for repairs.
Start with a quick visual safety scan of your Knoxville garage door
Stand back and look at your garage door from the driveway. Are there visible gaps between the door panels? Rust streaks or peeling paint near the hinges or tracks? These can signal misalignment or wear that may lead to bigger issues. Check the weatherstripping along the bottom edge—if it’s cracked or missing, cold Knoxville winters or summer storms can let in water, pests, or even carbon monoxide from your car. Also, inspect the cables and springs for fraying or rust. If anything looks off, don’t touch it—these components are under extreme tension and can cause serious injury. Instead, note the issue and move to the next safe step: testing the door’s balance. Learn more about our full list of services.
Test your garage door balance safely from inside your Knoxville home
Disconnect the opener by pulling the release cord (usually a red handle hanging from the opener rail). Now, manually lift the door halfway. Does it stay in place, or does it drift up or down? A balanced door should hold its position. If it falls or rises on its own, the springs may be worn or improperly adjusted—this is a job for a professional. Avoid forcing the door; imbalanced doors can snap cables or damage the opener. If the door balances correctly, reconnect the opener and test it. If it still feels heavy or jerky, the issue may be in the tracks or rollers—both areas where DIY adjustments can worsen the problem.
Listen and feel for common garage door noises in your Knoxville home
Turn off the radio and close the garage door. Listen closely: squeaking or grinding usually means dry rollers or hinges need lubrication. A loud bang or popping sound when the door opens or closes often points to a spring issue—especially in older Knoxville homes with frequent temperature swings. Vibrations in the door or opener can signal loose hardware or an unbalanced door. If you hear grinding or feel excessive vibration, stop using the door immediately. These sounds can precede a sudden failure, like a snapped spring or detached cable, which poses a serious safety risk. Lubricate only the rollers, hinges, and tracks with garage door-specific lubricant—never the springs or cables.
Check the tracks and rollers for wear and alignment in your Knoxville garage
Inspect the vertical and horizontal tracks for bends, dents, or debris. Use a level to check if the tracks are plumb (perfectly vertical). Misaligned tracks can cause the door to bind or come off the rollers. Clean the tracks with a damp cloth to remove dirt or grease buildup. Next, examine the rollers—plastic rollers wear out faster than steel, especially in Knoxville’s humid summers. If a roller is cracked, split, or wobbling, it’s time to replace it. Avoid adjusting the tracks yourself; improper tightening can warp them or void your warranty. If the tracks are damaged or the door still doesn’t move smoothly, call a pro to realign or replace them.
Know the garage door warning signs that mean stop and call a pro in Knoxville
Some issues are red flags for immediate professional attention. If your door slams shut, rises too quickly, or won’t stay closed, the springs or cables may be failing—these are under extreme tension and can cause severe injury if mishandled. A door that’s off its tracks or has visible gaps wider than a credit card can also be dangerous. Strange noises like loud bangs, grinding, or scraping often indicate a mechanical failure. If your opener is more than 10 years old or the door is over 15 years old, consider a full inspection—older systems in Knoxville homes may not meet current safety codes. Never attempt repairs on springs, cables, or the opener motor yourself.

Frequently Asked Questions
Why does my garage door in Knoxville make a loud grinding noise when it opens?
A loud grinding noise usually means the rollers or hinges are dry or worn out. In Knoxville’s humid climate, metal parts can corrode or seize up faster. If lubricating the rollers and hinges with garage door-specific grease doesn’t help, the issue may be a failing spring or misaligned tracks. Stop using the door and call a pro—grinding can precede a sudden failure, like a snapped spring, which is extremely dangerous.
My garage door in Farragut won’t stay closed after a storm. What should I check first?
First, inspect the weatherstripping along the bottom edge for tears or gaps—storm debris can damage it. Next, check the tracks for bends or obstructions caused by wind or fallen branches. If the door still won’t stay closed, the issue may be a broken spring or misaligned safety sensors. Avoid forcing the door open or closed; this can worsen the problem. Call a licensed pro to diagnose and repair the issue safely.
How often should I schedule a garage door inspection for my Knoxville home?
Knoxville homeowners should schedule a professional inspection at least once a year. Older doors (over 10 years) or those showing signs of wear need more frequent checks. Regular maintenance prevents costly repairs and ensures your door meets local safety codes. Lennox B. Garage Door's Repairs Inc offers seasonal tune-ups to keep your door running smoothly year-round. contact pricing
