Common Causes & Fixes for an Uneven Garage Door

An uneven garage door can be caused by various factors, from simple maintenance issues to more serious mechanical failures. Understanding the root cause is essential for determining the best fix. Below is a breakdown of common reasons for an uneven garage door and how to resolve them.

Cause How It Affects the Garage Door How to Fix It
Lack of Lubrication Friction increases, causing uneven movement. Apply a high-quality garage door lubricant to rollers, tracks, and hinges.
Loose or Worn-Out Hardware Misalignment due to bolts, screws, or hinges becoming loose. Inspect and tighten all bolts and screws; replace rusted or worn-out parts.
Damaged Rollers or Tracks Worn-out, bent, or damaged rollers prevent smooth movement. Inspect and replace damaged rollers; straighten bent tracks with a rubber mallet.
Broken or Worn-Out Springs Unequal lifting force leads to imbalance. Visually inspect for wear; contact a professional for replacement.
Misaligned or Loose Belt/Chain Causes uneven movement in garage door opener systems. Tighten the tension adjustment screw or replace a worn-out belt/chain.
Sensor Issues Misaligned or dirty sensors prevent proper closing. Clean sensor lenses; adjust sensor brackets for proper alignment.
