What Is on the Truck

Most houses in Mountain Park went up around 1979, and the wider service area's stock runs 1951 to 2012 with a median closer to 1978.

Never-swapped original parts

That matters for one reason: a lot of these garage doors have never been swapped out. The original torsion spring, the original rollers, sometimes the original single-layer steel panel, all still hanging on the same track it came with from the factory.

Cycle-rated springs on hand

Springs are rated for a cycle count, not a calendar date, but a door that age has usually burned through that rating twice over. The truck carries both torsion and extension hardware, because older Mountain Park openings were built for either, and we size the new door to the opening you have rather than forcing a standard size.

Insulated steel as default

We stock insulated steel sections as the default here - the service area sits in a cold-but-moderate climate band, cold enough that an uninsulated single-layer door loses real heat through the garage into an attached house, but not cold enough to require the thickest commercial-grade foam cores some northern climates use. Track, hinges, end bearing plates, and a torsion spring sized to the new door's weight all go in with the install - we don't reuse 1979 hardware on a new door, even when it still turns.

Getting It Booked In

We run this job out of Lilburn, and Mountain Park sits about 3 miles out, which keeps it a straightforward same-trip job rather than something we have to schedule around a longer drive.

Opening measurements first

Booking starts with a few questions about the opening: width, height, whether it's a single or double bay, and what's currently installed, since a lot of these 1979-built openings were framed before double-car doors with heavier insulated panels became standard and the jamb sometimes needs a small adjustment to take a new door square.

Opener rating for heavier door

We ask for the opener model too, if there is one, since an opener built for a lighter original door may not be rated to lift a heavier insulated replacement. That's not always the case, but it's common enough on houses this age that we check before the appointment rather than finding out with the new door half-hung.

Same crew, no separate dispatch

Once we've got the opening measurements and a sense of what's on the opener, we set the install date. There's no separate Mountain Park dispatch - the same crew and truck that handles installs across the area handles this one.

The Cost of This Job

We're not going to put a number on this page, because the honest answer is that it depends on door size, insulation level, and whether the opener needs replacing alongside it - and giving a flat figure here would be a guess dressed up as a fact. What we can tell you is something about who's buying: Mountain Park's median household income runs $95,678, noticeably above the $78,317 median across the broader service area. In practice that tends to show up as more owners choosing insulated steel over the bare minimum, and more double-door replacements done in one visit instead of staged over separate jobs.

The real cost drivers are the same ones that apply to any 1979-era opening: whether the jamb needs squaring, whether the opener survives the swap or needs replacing with it, and whether you want a basic panel or something with higher insulation and a longer warranty on the finish. We'll price the actual opening in front of us, not a generic door size, because two houses built the same year in this area rarely have identical openings.

What the Repair Takes

A full new-door install on a house this age usually means pulling the old track and spring assembly entirely rather than reusing any of it - by 1979-vintage standards, the mounting hardware doesn't match the lift requirements of a modern insulated door anyway.

New track and force reset

We set new track, new end bearing plates, a spring sized to the new door's actual weight, and run the opener through a full force and travel reset once the door's hung, since an opener tuned for the old door's weight will either slam or stall on the new one.

Special-order lead times

Here's the limitation worth knowing up front: custom widths, specific color finishes, and certain insulated panel styles are special-order items, and those lead times run longer than a stock door - sometimes a week or more depending on the manufacturer's schedule, which we don't control.

Standard sizes ship fast

If your opening takes a standard width and you're fine with stock colors, we can usually install from what's already on the truck or get it within a few days. If you want a nonstandard size to match a 1979 opening that was framed before standard widths were as uniform as they are now, plan for the order lead time rather than a same-week install.

Questions

Common questions

Is my original garage door hardware from 1979 still safe to use?

Probably not, even if it still opens and closes. Torsion springs are rated by cycle count, not years, and a door that age has typically exceeded that rating well before now. We replace the spring, track, and bearing hardware as part of any new door install rather than reusing original parts from a house this age.

Do you have a branch in Mountain Park?

No. We run out of Lilburn, about 3 miles from Mountain Park, and cover the install from there. There's no separate depot or local crew - the same truck and team that installs across the service area handles Mountain Park jobs on the same schedule.

Will my old opener work with a new insulated door?

Sometimes, but not always. Openers sized for an older, lighter single-layer door can struggle to lift a heavier insulated replacement safely. We check the opener model against the new door's weight before install day and flag it if it needs replacing alongside the door.

How long does a custom-size door take to get installed?

Longer than a stock size. Custom widths and certain finish or panel options are special-order items that can take a week or more depending on the manufacturer, which is outside our control. Standard widths in stock colors can usually go in much sooner.
