What You Are Seeing
The early signs are a grinding or rattling sound as the door travels, a door that hesitates or jerks at certain spots in the track, and a track that looks shiny or grooved where a roller's been rubbing metal-on-metal instead of rolling. On a door this age, the roller stems can also be worn thin enough that the roller wobbles side to side instead of sitting flush in the track. If you see flat spots on the roller wheel itself, or rust streaks on the track below the roller, that's wear that's been building for years, not weeks. A door that's started to sag slightly on one side while running can also point to a roller or hinge that's given up on that corner.
What It Costs
We don't post a flat number for this because roller count, roller type (nylon vs. steel vs. sealed-bearing), and whether the track itself needs straightening or replacing all change the bill. A full roller set swap on a standard double door costs less than letting a seized roller tear up a track or strip a cable, which is the direction this fails if it's ignored. We'll give you the number for your door before we start, not after.
What the Repair Takes
Swapping a full roller set on a double door is usually a half-day job including an alignment check on the track once the new rollers are in - on a 1984-era door, we always check alignment, since four decades of minor settling or track adjustment attempts tends to leave things slightly off even when the rollers were the only failure. We balance the door and run it through a full cycle before we call it done. If the springs are original too, we'll flag that separately rather than bundle it in without asking.
Getting It Booked In
We come out to Cottage Lake from Mill Creek, about 10 miles each way, so we schedule the visit rather than drop by unannounced. Tell us the sound and when it happens - on the way up, on the way down, at a specific spot - and we can usually tell you what we're bringing before we're on site. See our Cottage Lake coverage page for the rest of what we handle out here, or check roller replacement details for Mill Creek if you're comparing notes with a neighbor closer to the shop.
