Sealing Side of garage door

Wind, rain, and dirt can enter your garage through a garage door with improperly sealed sides. The open walls of the garage make it possible for rodents and reptiles to enter. In addition to safeguarding the items you have inside, proper sealing can also help you save money on your energy costs.

You need the correct tools to seal a garage door’s sides. The most crucial component is a weatherstripping seal, but you’ll need other tools to attach it to the door frame. A hammer, a pneumatic drill, and some nails are among them. The seal can alternatively be held in place with adhesive.

The measures you must take to effectively seal the door will be covered in more detail in the following paragraphs. With the procedure described in this post, you may do the DIY project in less than 30 minutes.

What Makes a Garage Door Seal?

You would want your garage to be warm, cozy, and weatherproof if you used it for more than just parking your car. You can maintain the room’s temperature and, as indicated, prevent rodents and other animals from entering if your garage door is securely sealed.

Rodents can gnaw their way inside cupboards and do a lot of damage if your garage doubles as an office or a store. The effects of the infestation may go much beyond your garage and into your living areas, depending on the layout of your property.

Your garage floor becomes wet when it rains. It can be a signal that the seal needs to be tightened up more. The sides, top, and floor of the door have cracks that allow water to leak in. Fortunately, anyone can seal the garage door if they have the necessary tools—some of which you might already own.

Check for openings at the top and bottom while keeping an eye on the sides of the garage door. When the door is closed, is there any area where you can see sunlight? It must be sealed if that is the case. How do you begin sealing the sides of your garage door?

Steps on How to Seal the Sides of Garage Door

1. Purchase your supplies

You need to gather all the required materials before you can begin sealing the sides of the garage door. The weatherstripping seal is the most crucial thing on the list, as we’ve already indicated. Although they are normally offered in rolls, a utility knife can be used to cut them to length. The seal blends well with the style of your door since it resembles painted wood.

You’ll need a hammer, some nails or screws, a pneumatic drill or stapler, and the seal to install it. Nails or screws may be included with the weatherstripping kit by some vendors, including Auto Care. However, adhesive or a sealant can also be used to install the weatherstripping seal.

Even if you want to use nails, you should think about obtaining caulking since it might help the seal last longer.

You’ll need cleaning supplies if you want to utilize glue in the process rather than nails and screws. If you want the glue to hold the weatherstripping seal to the garage door jamb correctly, it needs to be very clean.

2. Measure the area

Measure the width of the garage door and note it to determine how much weatherstripping seal you require. Add two to the door’s height measurement to get its width. To determine how many feet of seal you need to purchase, add the two results together.

3. Old Seal to be Removed

Skip this step if you have never installed a weatherstripping seal on your garage door. Before you fix the new seal, you must remove any that you or the previous owners may have already installed on the door. To remove the seal, you’ll need a powerful utility knife or a crowbar like the Vaughan B215.

Simply insert the knife or crowbar under the seal to look for the nails keeping it there. Lift and get rid of them. When you’re finished, check the door jamb to make sure you haven’t harmed any of its components.

To work on the jamb and restore its smoothness, use sandpaper like the 3M Garnet and wood finish like Minwax Polyshades. If removing the nails left too many holes, you might fill them in with wood putty or fillers like Elmer’s E855.

4. Set up the fresh seal

It’s time to fix the seal after you’ve cleaned off the jamb surface.

Measure the door’s sides once more, and then cut the seal to match. Keep in mind that a knife can easily cut through the seal. Don’t cut to the precise size. Give yourself some leeway in case you make a calculating error.

It’s time to start the installation process after you’ve cut the seal. The top and sides of the garage door should be sealed first if you’re doing both. The suggested method for ensuring appropriate meshing between the sides and top seal is as described above.

The seal’s installation actually only requires a few simple steps:

Drive the nails or screws through the jamb’s thicker areas while pressing the seal against it. If the package didn’t include any nails, you should buy some that are an inch and a half long. At first, don’t fully drive the nails. To rule out any gaps, you must first inspect where the seal is placed. You must be certain since you are sealing the garage door sides to avoid creating such gaps in the first place. Watch for any gaps between the seal and the garage door after pushing it to lap it. Remove the nail that is closest to the gap and adjust the seal if you discover any. You can fully penetrate the nails once there are no longer any gaps.

For a tighter seal, use caulk.

There would still be very small gaps near the spot where the nail meets the jamb despite your best efforts. The seal may fail more quickly if these holes are ignored. If you need to use the seal to keep heat inside, you shouldn’t disregard it either. The easiest technique to seal these gaps is with caulk or another silicone sealer.

Between the seal and the door frame, insert the sealant. For optimum application, you must cover your fingers with a protective covering. You could omit this step if you applied glue to the seals’ connections.

Ensure Your Garage Door’s Bottom Is Sealed

If the bottom side of your garage door is open, sealing the top and sides might not be sufficient to give you the airtight protection you need. Use a bottom or threshold seal to seal the garage door’s bottom sides.

The bottom seal installation is equally straightforward as the sides. Manufacturers like Bowsen offer bottom seal kits, like the Bowsen Garage Door Retainer Kit, that comes with the kit and screws to hold them in place. It’s time to go to work after you’ve bought the seal.

In practice, installing the top and sides is fairly similar to how we described it above.

Remove the outdated bottom seal. For metal garage doors, you may simply slide this out; however, for wooden garage doors, you will first need to use your crowbar to remove the nails holding it in place.

the surface was thoroughly cleaned. The installation will go much more smoothly as a result, as you can see above, and the seal will adhere to the surface more readily.

The area is measured. Once more, knowing how much of the seal to cut will be made easier with this. You can cut your seal if you previously measured the bottom area before purchasing it.

Place the replacement seal in its place on the door’s floor. For the seal to fit into, metal garage doors will have a defined area; however, with wooden garage doors, the seal must be installed on the ground. Close the garage door and look for lumps and voids before securing the seal with screws and adhesive.

Keep the seal in position. Once you’re certain the seal is in the proper place on the floor, fasten it there with screws or glue. After finishing, you should gently shut the garage door. If you used glue, you should at least give the glue a day to dry. Although it might dry more quickly, be safe.


The best way to keep out water, snow, insects, rodents, and reptiles is with a properly sealed garage door. Sealing the garage is a wonderful technique to guarantee that it will be pleasant in the summer or winter if you spend a lot of time there.

You can finish the procedure on your own using the strategies we’ve described above. After purchasing the seal, you can also hire a professional to complete the work if you don’t have the necessary tools or don’t want to do it yourself. It is a straightforward task that can be finished in under an hour. You can hire a pro at Temecula, CA for any kind of garage door service.
