A lot of homeowners here look at a rattling door and figure they'll just swap the rollers themselves. If your house is one of the newer builds that make up most of Thompson's Station - median year built is 2013, the newest stock anywhere in the area we cover - you're dealing with a factory door still on its original nylon rollers, usually on steel tracks with tighter tolerances than older doors use. That's not a hard job if you know what you're doing. It is a job where the wrong roller stem length or a track that's slightly out of plumb turns into a bent track or a door that jumps off the rail. If you're comfortable with a ladder, winding bars, and working around a loaded spring system, a straight roller swap on a newer door is doable. If the door binds, skips, or the opener strains to pull it, stop and call - that's usually not a roller problem anymore.
