Installing a new garage door can be a big job for most, however, if your existing garage door is twenty years or older, this is a job you may want to consider doing.  There are many garage door install companies on the market, but for the handyman and many others, you can achieve the task with these helpful installation guidelines.

Where Do I Start?

If this is a new construction job, framing the rough opening is the first step to the installation process and will usually be a two person job.  After the concrete slab is poured and set, you can use the slab as your workspace to fabricate the walls.  The framed walls are tied into a sill plate, most commonly using 2 x 4 pressure treated lumber.  This is drilled and fastened to the anchor bolts. Next, mark the sill plate, as well as the top plate locating the wall studs and mark for the garage door opening and then assemble the wall studs to the sill and top plate.

When the wall of the garage is erected, tighten the anchor bolts to hold the wall in place, adding braces for additional support.  When you are certain the walls are squared up, toenail them together and sheath the walls, generally using 4 x 8 sheets.

Door jambs finish the rough opening of garage door.  Screw side jambs to the trimmers for correct door width, back jambs should be flush with corner side jambs.  The garage door brackets will mount to the back jambs, you will want to be sure this is squared up.

Installing The Garage Door

Once you have constructed the garage itself, or if you are replacing an existing door, you will fasten door panel roller brackets and place the bottom panel in the threshold, toenailing it to the side jamb to be sure it is level.

Put up any remaining panels and install the connecting hinges, handles and rollers.  Next, assemble side roller tracks using a ¾” spacer block while putting the track together and when side track is in place, fasten it permanently to the back jamb, repeating for opposite side.

Next, bolt the top track to side track, level and lag screw the rear bracket to the nearest roof truss.

Checking gaps at top of tracks, you will need to lift the door about 4’, this may take additional people to help.  With the door up, clamp locking pilers  on track to keep the door in place. Check the gap once more, making sure there is not a variance more than 1/8” or you may need to adjust the top track.

Finally, connect the extension springs to rear bracket by mounting the front brackets supporting pulley and cables.

Fasten cables to bottom hardware and feed through the bracket and pulley spring and fasten to the front bracket.  Push the cables through the springs and attach to front and rear brackets.

Of course you could hire a company like TXOHD; however as mentioned above this can be a lot of work for some, but using do it yourself tips can save you a lot of money in the end and prove even to the least handy person that this can be done.
