How To Fix a Gap 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 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.

• How to Fix: This usually requires professional realignment. A technician can safely ensure the tracks are parallel and stable.

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.

• How to Fix: Replacing the weatherstripping is typically straightforward. Consult your door’s manufacturer or B&D for compatible materials and follow the instructions for installation.

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.

• How to Fix: You may be able to reinforce the door, but if it’s too warped, a replacement might be the only option. Contact a professional installer for an evaluation, especially if you suspect warping.

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.

• How to Fix: A qualified garage door technician can assess and correct installation errors. If your door is still under warranty, verify whether the manufacturer covers installation issues.

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.
