New Garage Door Installation for Peachtree Corners Homes

Why This Fails Locally

The problem we see most in Peachtree Corners isn't age for age's sake - it's what the builders used in 1988, which is roughly when most of this area went up. That's a full decade after the median build year of 1978 across the rest of the territory we cover out of Dunwoody. Builders in the late 80s were putting up a lot of houses fast, and garage doors got the same treatment as the rest of the trim package: lightweight steel panels, thin-gauge tracks, and torsion springs sized to the bare minimum for the door that shipped with the house.

Thirty-plus years later, that spec shows up as doors that feel heavier than they should, openers straining on lift, and springs that were never rated for anyone swapping in a heavier insulated replacement door later on. If you've already had a door swapped once in this neighborhood, there's a decent chance the spring never got upsized to match it. That mismatch is the root of most of the service calls we run out here, not rust and not storm damage.

What Is on the Truck

We run the 5 miles out from Dunwoody for every Peachtree Corners job - there's no branch or drop point in the suburb itself, so what goes out on the truck is decided before we leave. For new installs here, that means torsion springs rated above the stock 1988-era sizing, since most replacement doors now weigh more than what came with the house.

We carry standard residential track in both 2-inch and 3-inch sections, since houses from this build era were fitted inconsistently depending on the builder. We also stock the mounting hardware for steel jambs, which is what you'll find on most of these garages rather than the wood jambs common in older construction closer to Dunwoody proper. One limitation worth saying plainly: specialty widths, custom insulated glass-panel doors, or anything outside standard residential sizing has to be special-ordered, and that adds lead time we can't shorten from our side.

Where This Job Goes Sideways

Peachtree Corners sits in the same cold-moderate climate band as the rest of the service area, but the construction here is different enough that the failure points aren't identical. Newer slab-on-grade garages built in the late 80s don't flex and settle the way older framed houses do, so when a track goes out of plumb here, it's usually a hardware or install issue rather than decades of foundation movement.

The other place this goes sideways is on the spring swap. Because the original torsion springs were undersized to begin with, a straight one-for-one replacement during an install often leaves the new door feeling just as heavy as the old one. We size the spring to the door you're putting in, not to what's already on the shaft - skipping that step is the single most common corner cut on jobs like this, and it's the one that brings people back six months later.

What You Are Seeing

If your door is from the original 1988-era build and you haven't touched it, you're probably seeing a door that's slow to respond, an opener that strains audibly on the way up, or a door that reverses on its own partway through closing. None of that is dramatic failure - it's a system that was speced thin from the start finally running out of margin.

If you've already replaced the door once without touching the spring, you might be seeing something different: a door that closes fine but feels like it's fighting you on manual lift, or cables that look slightly slack at rest. That's the mismatch between an old spring and a new, heavier panel. Either way, the fix starts with sizing the hardware to the door you actually have now, not the one the house came with in 1988.

What the Fix Involves

A new install here starts with pulling the old track and spring entirely rather than reusing what's there - given the age and the original undersizing, trying to save the existing hardware usually costs more in callbacks than it saves. We size the torsion spring to the actual weight of the new door, not the opener's rated lift, and we set the track to plumb against the jamb rather than against whatever reference point the old track left behind.

Most standard-width steel doors go in on the truck's existing stock, which keeps timelines short. Anything custom - oversized, oddly proportioned, or a specialty material - has to be ordered in, and that's a lead time we don't control. We'll tell you up front if your job falls into that category rather than quoting a date we can't hit.
