Can You Do This Yourself
You can. A basic chain-drive swap on a door that already has good track and a sound header is within reach for someone comfortable with a drill and a ladder. Where people get into trouble on houses this age is the wiring and the bracket, not the opener itself.
If your house still has its original header framing from 1978, don't assume it's rated for a modern belt-drive unit without checking. We won't talk you out of doing it yourself, but we will say: if you're not sure whether that bracket is original wood or already patched, get eyes on it before you hang anything from it. That's the one part of this job we don't recommend guessing on.
What the Fix Involves
On a house built around 1978, the job usually starts with pulling the old unit and inspecting the header bracket and rail mount before anything new goes in. If the bracket is original and sound, we reinforce it rather than replace framing that doesn't need replacing. If it's been patched more than once, we tell you straight and give you the option before we mount anything.
From there it's a standard install: motor unit, rail, sensors set at the code height, wall control, and a battery backup if you want one. Given the mild, humid climate here, we skip anything that needs cold-weather lubricant or heavy insulation packages meant for harsher climates - a straightforward chain or belt unit does the job without extra cost you don't need.
What You Are Seeing
The calls we get from this part of the service area follow a pattern: an opener that reverses on its own partway up, a motor that hums but doesn't move the door, or a remote that used to work and now only sometimes does. On houses this age, that last one is often a wiring or antenna issue tied to an old control board, not the remote itself.
Another common one is a door that closes, then pops back open a few inches - usually the safety sensors are misaligned or, on an older setup, missing altogether. If you've got a single button wall switch with no keypad and no light, that's a sign the whole unit predates a lot of the safety hardware that's now standard, and it may be worth replacing outright rather than patching.
Getting It Booked In
We run this job out of our Texas City location, about 8 miles from La Marque, so we schedule the visit rather than drop by unannounced. Bring us the age of your house and whether the opener has ever been replaced, and we can usually tell you over the phone whether you're looking at a straight swap or a bracket repair first.
See our La Marque garage doors page for the rest of what we cover in this area, or the opener installation page for Texas City for the full rundown on unit types and options we install.
