What It Costs
We don't quote a number sight unseen, because the job changes with what's on the door. A full set of ten rollers is a different job than three rollers and a bent track hanger, and steel ball-bearing rollers cost more than nylon ones. What we can tell you is that in a neighborhood like Tega Cay, where the median house went up around 2006 - the newest end of the 1979-2006 range across the wider Fort Mill service area - most of what's on the door right now is original. That matters for pricing because original builder-grade rollers are almost always the cheap stamped-steel or hard plastic kind, not the sealed nylon rollers worth upgrading to. We'll tell you on site which one you've got and what swapping the full set runs, rather than guessing over the phone.
Can You Do This Yourself
Roller replacement on the bottom panels, done one at a time with the door down, is within reach for a careful homeowner with the right tools. The top rollers, the ones that ride near the spring and the bent part of the track, are a different story - you're working close to a torsion spring under load, and on a double door that spring is strong enough to break a hand if the door drops wrong. If a roller has already jumped the track or the track itself has pulled away from the jamb, stop. That's not a roller job anymore, it's an alignment problem, and forcing the door on a bad track usually bends something else.
Where This Job Goes Sideways
The most common surprise on a 2000s-era Tega Cay door is corrosion inside the roller stem, not the roller wheel itself. The wheel looks fine, you pull it, and the stem comes out pitted or seized in the bracket - a sign the roller's been seizing and dragging rather than rolling for a while. Cold mornings make this worse: the plastic in an original roller stiffens up and can crack rather than spin on the first really cold start of the season. The other place it goes sideways is a track that's been bent slightly out of true by a dragging roller for years - replace the roller and ignore the track, and the new roller wears the same way in half the time.
Parts We Carry
We carry both nylon rollers with sealed ball bearings and standard steel rollers on the truck, in the common stem lengths and wheel sizes used on residential sectional doors. Nylon is quieter and runs longer, which is usually what we recommend once we're already replacing a full set - there's little reason to put another builder-grade steel roller back on once it's open. We also carry the roller brackets and hinges that mount them, since a bracket worn oval from years of a loose roller won't hold a new one straight. What we don't stock are oddball commercial-grade rollers or anything off a specialty door - those get special-ordered, and that adds lead time.
