How to Adjust a Garage Door Gap

There are plenty of reasons you’ll need to fix a gap on your garage door. Firstly, gaps can be a major security risk to your home as they are an invitation to burglars to try and force the door open and get inside. A gap can also be unsightly and affect your home’s curb appeal, especially if you’re looking to sell your home. It helps, therefore, to learn how to adjust a garage door gap.

How to Adjust a Garage Door Gap

This article outlines a few tips on adjusting a garage door gap. It outlines the items to check ranging from the stops to adjust limit switches to replace the seal.

Check the Stops

The stops refer to the rubber seals running along the edges of your automated garage door. They create a seal when your garage door is closed, keeping the weather out and preventing the door from staying open. If your garage door has gaps, it’s likely the stops aren’t aligned correctly on the door. You either have to get them replaced or moved closer to the gaps.

Look at The Tracks

Check whether the door is perfectly vertical when closed. If not, you’re likely to have gaps around the door. Fixing this is simple and you can even do it on your own. Start by looking at the vertical tracks that your garage door travels on. If they’re not holding the door at a consistent distance from the stops, adjust the door so it sits closer to the stops by loosening the mounting bolts and moving them slightly.

Adjust Your Limit Switches

Your limit switch determines where your garage finishes when you shut it. If the settings are not quite right, the door will have a gap and it can even cause your garage door to jerk. The flexible seal at the bottom can also affect the gap. The trick here is to adjust the limit switch so the seal is compressed to the floor, sealing the gap. The limit switch is usually found with the opener but be sure to read the instructions for your particular door opener as many have different settings. Your limit switch is also the easiest way to adjust your garage door height

Replace the Seal

If the seal is not sitting flush with the floor, that can also be a problem. This may be a result of wear and tear, which is quite normal with garage doors. You can replace a seal yourself. Pick up a new seal at your hardware store and follow the instructions to ensure it closes the gap correctly.

Trim the Door to Fit

Garage doors typically have a settling problem as it changes the way the door sits in the frame. If you have a wooden garage door, you can simply trim the door so that it fits properly. You can use a circular saw or jigsaw, sand off the bottom and replace it in the frame. If you don’t have a wooden garage door, you may be looking at a replacement.

Bottom Line

The points mentioned have covered most of the tips on how to adjust a garage door gap. Other options include installing a garage door threshold or adding more concrete to the floor. However, sometimes you may not be able to identify the cause and that’s when you need to call in a professional garage door installer.
