The Complete Garage Door Installation Guide (with Epoxy Floors)

Installing a garage door may seem like a difficult DIY project, but with the right tools and materials, it isn’t as challenging as you might initially think.

Here’s a simple guide to follow when installing a new garage door for your home.

Gather All of the Tools and Materials Needed

To adequately prepare for a garage door installation, make sure you have the following tools:

  • 4′ level
  • drill
  • sawhorses
  • hammer
  • measuring tape
  • Phillips-head screwdriver
  • flat-head screwdriver

As for materials, all you need in most cases are wood jambs.

Step 1: Remove the Old Garage Door

Based on the manufacturer’s instructions, remove the old door, which typically involves unlatching the door from the pulley system, deconstructing the door panels, and unscrewing the tracks. Only remove one panel at a time, or they could all collapse.

Step 2: Measure and Attach Handles and Hinges

You’ll want to measure the areas where you plan to install the doors. These areas include door-opening height and width, back room (garage’s length) and headroom (from top of opening to ceiling).

Headroom should ideally have about 10″ to 12″ of space, depending on the type of spring system. Back room should include the door height and 18″ of space or more.

Once you’ve taken the proper measurements, you can attach stops to both sides of the opening and ensure they are flushed using the inside edge of the wood doorjamb.

Then you can use the sawhorse to lay out the bottom piece of the new door, and attach any lift handles, hinges, and weather stripping.

Step 3: Place the Bottom Panel in the Door Frame

To start installing the new garage door, place the bottom piece in the door-frame and use your level to make sure it’s sitting evenly. To secure the panel in place, tap nails partway in each jamb, and slant or bend them slightly to further secure them.

Following the installation of the bottom panel, install the rest by repeating the same process.

Step 3: Install Garage Roller Systems

After all of the panels are secured, it’s time to install the roller. With the roller supports in place, place the rollers in the assembled track and secure the brackets as you go along.

However, they shouldn’t be too tight against the track, or the friction could potentially damage the door.

Step 4: Secure Tracks in Place and Attach Springs

Once the rollers are in place, you can install the horizontal and curved track pieces. Make sure that tracks are straight and pointing away from the garage door opening at 90 degrees, using previous measurements along with your level.

After you’ve secured the tracks, assemble the springs based on the manufacturer’s instructions, and lift the door halfway to make sure the tracks are parallel and level.

If you’ve determined it’s working the way it should, lift it up all the way and attach the springs to the pulleys.

When Replacement Isn’t Needed

Keep in mind that the only time you’ll need to replace your garage door is if the garage door fails to function entirely, or if you’re simply tired of the current garage’s appearance.

If you need repairs, you may want to contact garage repair professionals, who can also help with replacement in many cases.

Apply an Epoxy Garage Floor (Tips)

When you have your door installed, then you can apply epoxy to the floor. The most important part of this process is the preparation. Take time to prepare your floor correctly.

Read instructions thoroughly before starting.

  • Inspect the floor
  • Do a moisture test
  • Clean the Garage Floor
  • Profile the floor
  • Complete your repairs

After you have completed all these steps, you will have an awesome garage.
