How To Fix a Gap on One Side of Your Garage Door

Your garage door should fit snugly, leaving no gaps around it. Over time, however, new buildings settle, components may shift, and materials can wear down sometimes leading to gaps. If you notice gaps on any side of the door, it’s important not to ignore them, as these can result in drafts, water leakage, easier pest entry, and even damage to your door or opener. Below, we discuss potential causes and what you can do to address gaps on one side of your garage door.

Causes and Fixes for Gaps on One Side of Your Garage Door

There are several reasons why a gap might form on one side of your door. Identifying the specific cause with your door is crucial before trying any repair.

Misaligned Tracks

Misaligned tracks are one of the most common causes of a gap on one side of a garage door. Over time, the tracks that guide the door can shift or loosen, causing an uneven door position.

Worn or Damaged Weatherstripping

Weatherstripping along the door’s edges helps form a seal when closed. When it becomes worn, cracked, or otherwise compromised especially on older doors or those exposed to harsh climates gaps may appear on one side.

Sagging Garage Door

Doors made from wood or other materials can sag over time if not adequately maintained. This may result in an uneven alignment and cause gaps.

Incorrect Installation

If a garage door was installed improperly, it might not sit evenly in the frame. This misalignment often leads to gaps on one or multiple sides.

When to Call a Professional

Some minor issues like replacing weatherstripping can be a DIY project, but problems like misaligned tracks, sagging, or botched installations typically require professional expertise. Attempting these complex fixes alone can risk further damage or even personal injury, especially when dealing with springs and cables under high tension.

A certified technician has the tools, experience, and knowledge to diagnose the cause of the gap and recommend the most effective remedy. They’ll ensure the repair is both safe and compliant with any warranty. Routine garage door servicing can also catch potential issues before they escalate.
