What Is on the Truck
For a straight swap - same rough opening, no framing work - the truck carries standard steel and insulated door sections in the common widths, torsion springs sized by weight and cycle count, new rollers, cable, and track hardware, plus a couple of opener models if the old one's being replaced too. For Coral Gables specifically, we carry extra jamb material and a wider range of track brackets, because a house built in 1968 doesn't always give you a clean 16-by-7 or 9-by-7 opening to work with. What we don't stock on the truck is custom millwork doors or anything built to order - those get quoted and ordered ahead, not installed same-visit.
What Can Go Wrong
The most common surprise on a 1968-era Coral Gables garage is that the opening was never square to begin with, or has shifted slightly over five decades of settling. You measure the door width and think you're done, but the header's out of level by half an inch, or the studs on one side aren't plumb, and a standard door won't seat right without shimming the frame first. The second issue is track clearance - garages from this era were sometimes built with less headroom than current codes assume, which limits which spring and track configuration will actually fit above the opening. Both of these show up during the walk-through, not on a phone call, which is why an accurate quote here needs someone standing in the garage.
Can You Do This Yourself
Hanging a garage door yourself is possible if the opening is standard and you're comfortable with high-tension spring work, which we don't recommend without the right bars and clamps - a torsion spring under load has hurt plenty of careful people. On a Coral Gables house with an older, non-standard opening, the honest answer is this isn't a good first DIY project: you're not just hanging panels, you're often correcting framing first, and getting that wrong means the door binds or the track pulls loose within months. If you want to swap an opener on an existing, properly-fitted door, that's a more reasonable weekend job. A full door replacement on an older frame is where we'd tell you to call someone.
What You Are Seeing
If your door is original or close to it, look for a single-layer steel or wood panel with no visible insulation core, hinges that have been re-shimmed more than once, and a track that doesn't run perfectly parallel to the floor. Daylight gaps at the top corners, a door that's noticeably heavier to lift by hand than it should be, or an opener that strains and reverses partway up are all signs the door and hardware are past matching each other correctly. None of that means the house has a problem - a lot of Coral Gables garages are original to a 1968 build and have simply never been touched. It means the door is due, and the replacement needs to account for the opening it's going into, not just the opening on a spec sheet.
