How to Adjust a Garage Door Side Gap?

This is not as easy as adjusting door hinges that we previously discussed. Side gaps on the door are probably the most common problem that most users face. This gap allows the intruders to tamper around the door and lets dust and debris get inside easily.

Sometimes it can be solved just by some garage door lubricants, and sometimes the problem is a little harder to crack. Nonetheless, the steps that you would need to follow to fix the side gaps are as follows:

Step 1: Check the Stops

First and foremost, you need to check the door stops. It is basically strips of trim that will run along both sides of the door. These strips cover the gaps between the walls and edges of the door. It will also cover the jambs, which will provide proper protection from the harsh outdoor environment.

If the stops are not working correctly, there will be a gap. And this gap can only be fixed by moving the stops closer to the door. If that does not solve the problem, opt for a replacement. You can find proper garage door stops in the hardware shops. But do make sure that the replacement is compatible with your door. You door insulation might also be messing with the closure. Give that a check too.

Step 2: Inspect the Tracks

The garage stops might not be the culprit. Instead, the tracks might be the ones that are causing the gap. In that case, you would need to check the vertical sections of the tracks. They will be present on each side of the door.

In the normal state, they will remain plumb and capable of holding the door at a consistent distance. You may also check that if your door roller are working properly. Because you might need to change the roller.

Inspect the Tracks

Usually, the tracks will be mounted on the brackets. And the brackets will have slotted holes in them. To fix the issue, you would need to loosen the mounting bolts a bit. Nudge the tracks a little and move the door closer to the plumb. After that, retighten the bolts while ensuring that the tightness is not too much.

On that note, do make sure that the plumbs do not go too close to the door. It does need some play to function and role optimally.

The garage doors leaving gaps at the bottom are not that uncommon. This will hinder the opening and closing of your garage door. If you are facing this issue, go through these steps:

Step 1: Make Adjustments on the Limit Switches

There is a high chance that the limit switches are off if the door does not close all the way down. The flexible seals are an easy target for the animals. You will even find bite marks on the seals. To prevent this, you would need to limit the switches. That will let the seal compress all the way to the bottom.

By limiting the switches, you can adjust the final position of the door. And this controller will usually be on the top of the opener. However, you would need to refer to the user manual before making any adjustments because the doors do not have a standard controller.

Step 2: Change the Weatherstripping

Replacing the weatherstripping can solve the gaps that remain on the bottom of the door. However, you might need to check out different types of stripping. First, consider the bulb seal. These are kind of like a flimsy garden hose. They will have a T-shape spine along the very top.

For the bulb seal, the spin will slide right into one of the grooves of the bottom panel. So, there will be no need to go through any hassles while trying to install them. Also, while choosing a bulb seal, opt for the largest diameter

Change the Weatherstripping

Secondly, try the U-shaped ones. These will have two edges that will slide right into the two channels of the garage doors. Ensure that the weatherstripping has enough height to cover the top gap.

Step 3: Replace the Seal

The original seal on the door might be the culprit. Over time, these can wear down and tear. But the good news is that replacing the seal is not that much of a hard task. Get yourself the best garage door seal that is compatible with your garage door. Consider the model and the name of the manufacturer of your door while purchasing.

On that note, the installation process will vary from one door to another. Some will require you to use a screwdriver to drive the screws through the predefined holes, while some will require you to feed the seal through the track or channel.

Step 4: Compensate for the Settling

If you find the gap still exists after carrying out all of the steps mentioned above, you need to follow this step. You might need to compensate for either the garage floor, the framing, or both. If the door is of wood and the gap is not that severe, trim the door on the bottom.

Compensate for the Settling

Match the widest part of the gap by using a compass. Drag the compass along the floor and use a pencil to mark out the cutting line. Cut the door using a circular saw or a jigsaw and sand it properly to obtain a proper finish. Then, install a new weather stripping.

Step 5: Add More Concrete

Another thing that you can try to fix the gap is by adding concrete to the flooring. It is pretty common for the concrete garage floorings to move or drop after they are poured. And this can be somewhat troublesome because the slabs will always move in parallel or even ways.

Nonetheless, add a couple of concrete slabs to level the surface of the bottom. Once the surface is leveled, there should not be any gap left.

Step 6: Install Door Threshold

Luck must not be by your side if the steps above do not work for you. But do not worry, we got another fix. You will find threshold kits available in automotive retailers and home centers. They will usually be of rubber and requires glue to set in place.

Install Door Threshold

All you need to do is glue the threshold in place. Once the glue bonds and the threshold settle in, the door will rest on it when it is in the closed position. This will protect the bottom of the door from damages and take care of the gap that it might be leaving at the bottom.

Final Words

Gaps in between the floors and side walls are not a good thing when it comes to garage doors. However, you do not have to worry one bit once they appear, as you now know how to adjust a garage door gap properly. Just follow the steps properly, and the gap should be gone entirely.
