How To Repair Overhead Garage Door
Understanding Garage Door Components and Repairs
Garage doors have two primary components: the door itself and the opener. Ensuring both are in top condition is essential for smooth operation and safety. In this guide, we’ll share professional insights to help you address common repair issues with the door itself. Let’s dive into practical repair steps for overhead garage doors.
Repairing Your Overhead Garage Door
Overhead garage doors, whether sectional roll-up designs or one-piece swing-up doors, operate using spring tension. They glide along metal tracks mounted on the garage walls, powered by one or more heavy-duty springs. When your garage door doesn’t function correctly, the solution is often straightforward. Here are detailed steps to help you troubleshoot and repair common issues:
Step 1: Inspect and Fix Metal Tracks
Begin by examining the metal tracks inside the garage. Check the mounting brackets that secure the tracks to the walls. If they’re loose, tighten the screws or bolts firmly. Next, inspect the tracks for dents, crimps, or flat spots. Minor damage can be resolved by using a rubber mallet or a hammer with a block of scrap wood. However, if the tracks are extensively damaged, they’ll need to be replaced.
Step 2: Ensure Proper Track Alignment
Improper alignment can hinder smooth operation. Use a level to check the horizontal tracks—they should slope slightly downward toward the back of the garage. Vertical sections of roll-up door tracks must be perfectly plumb. If you find misalignment, loosen (but don’t remove) the screws holding the brackets. Gently tap the tracks into place and verify alignment with the level before tightening the screws securely.
Step 3: Clean Tracks and Rollers Thoroughly
Over time, dirt and grease can accumulate, causing the door to stick or squeak. Use a concentrated household cleaner to wipe down the tracks and rollers. Once cleaned, dry them thoroughly to prevent future buildup.
Step 4: Tighten Hardware and Address Structural Issues
Loose hardware is a common culprit behind malfunctioning doors. For swing-up doors, check and tighten the screws on the plates where the spring is mounted. Roll-up doors require inspection of the hinges that connect the door sections—tighten any loose screws and replace damaged hinges.
If sagging occurs on one side, servicing the hinges often resolves the issue. For enlarged screw holes, use a longer screw paired with a hollow fiber plug dipped in carpenter’s glue. If the wood around a hinge is cracked, fill the damage with wood filler, allow it to dry, and reposition the hinge on solid wood.
Caution: Handle Torsion Springs with Care
Roll-up doors with a single torsion spring at the center require professional attention. These springs are under immense tension and can cause serious injuries. Always contact a qualified repair service for this type of issue.
