Things You'll Need:
- Measuring tape
- Pencil/paper
- Standard garage-door kit (will include the door itself, as well as any hardware, accessories and instructions)
- Electric drill or screwdriver
- Hammer
- Wood and metal screws
- Nails
- Other equipment, as specified in instruction/installation manual
-
Step 1
Measure the existing door opening of the shed to determine the size of garage door kit you will need to purchase.
-
Step 2
Garage door kits come in many different sizes, so it is very likely you will find one that matches your measurements. If not, simply enlarge the existing door opening to fit your specifications.
-
Step 3
Purchase the garage door kit.
-
Step 4
Once you are satisfied you are ready to begin, and have assembled all the necessary tools and accessories, attach weather stripping to the bottom of the first panel that is to be installed.
-
Step 5
Fit the first panel into the doorway and secure it by fastening nails to the jamb at an angle. Don’t hammer them in all the way; rather, leave them partially out. (You may wish to use an ordinary hammer and nails for this part.)
-
Step 6
Unless you have already done so, attach the hinges to the top part of the door, at the edge.
-
Step 7
Put the door tracks together, following the instructions provided with the kit.
-
Step 8
Find the brackets, rollers, and other parts that make the door go up and down, and fasten them to the tracks, wall and other places specified by the kit instructions.
-
Step 9
Pick a side and put the track on the bracket, following the instructions. Do the same to the other side.
-
Step 10
Continue to install rollers and other necessary equipment to the second section, and lift it into place. (This may require some help.) Then attach the first and second sections together at the hinges.
-
Step 11
Follow the same steps for the third and other sections, then check to make sure the door is level at the top and square on the sides.
-
Step 12
Continue to install the top tracks and other parts of the door, according to the manufacturer’s instructions.
