What It Costs
We don't quote a number here because the job varies more than people expect on a house this age. A straight roller swap on a door that's still square and running clean is one job. A roller swap on a door where the track has worn oval from fifty years of the wrong roller grinding against it is a different job, because now you're paying for track too. On Mercer Island specifically, we're seeing more of the second kind than the first, simply because so much of this housing stock dates to 1973 and nobody's opened up that hardware since. If your rollers are still the ones that came with the house, budget for the possibility that the track needs attention at the same time, not because we upsell it, but because worn track wears out new rollers fast and you'd be back here in a year.
We travel out from Seattle for this work, about seven miles each way, so we bundle the visit, we're not going to quote you a roller-only job and then discover the track on site and have to reschedule a second trip.
Doing It Yourself
Rollers are one of the more DIYable parts on a garage door, on paper. Pop the roller stem out of the hinge or bottom bracket, slide the new one in, done. The catch on a 1973 house is that the roller stem length and the bracket hole size on original hardware from that era often don't match what's sold off the shelf now. We've opened up plenty of these doors expecting a standard 7-inch or 10-inch stem and found something the manufacturer stopped making decades back.
If you're going to try it yourself, do the top rollers last, not first, they're under spring tension near the top bracket and that's where people get hurt. Test each side one roller at a time rather than pulling all of them and hoping the door holds itself up. And if a roller comes out corroded to the point where the stem snaps off in the bracket, stop, that's a sign the whole set has been seizing for a while, and forcing the rest out the same way usually costs you a bent track.
The Complications
Mercer Island sits in the same mild, occasional-freeze climate as the rest of the Seattle area, which is good news and bad news for hardware this old. Good news: no deep freeze-thaw cycle cracking the nylon rollers the way it would somewhere with real winters. Bad news: fifty years of damp Pacific Northwest air sitting on unsealed steel rollers and bare track bolts means we find more surface rust and seized bearings than cracked plastic here.
The other complication is the door itself. On a house built in 1973, the roller replacement sometimes turns into a bigger conversation once we're actually up on the ladder, hinges stretched from decades of the same weight riding the same three rollers, or a bottom bracket that's been rewelded at some point by a previous owner. We'll tell you straight if what you called about is a ten-minute fix or if it's the leading edge of something bigger. We won't sell you a full door replacement over a bad roller if a bad roller is genuinely all it is.
The Symptom
The classic sign on a house this age isn't a door that won't move, it's a door that moves loud. A grinding or clunking sound as the door travels, worse at the same spot in the track every time, usually means a roller bearing has gone dry or corroded and it's now riding flat instead of round. On original 1973 hardware that's never had a bearing replaced, that's not a maybe, that's the roller finally announcing itself after decades of quiet wear.
A second sign: the door hesitates or catches at roughly the same point on both trips up and down. That's usually a specific bad roller hitting a specific worn patch on the track, and it tells us where to look before we even get the door open. If instead the door is jerking unevenly on one side only, that's less likely to be a simple roller problem and more likely a cable or spring issue riding along with it, worth mentioning on the call so we bring the right parts.
Time on the Job
A standard roller replacement, all ten or twelve rollers, on a door where the track is still true, runs about the length of a short home repair, long enough to do the job right, not long enough to disrupt your day. Add real time if we find the track needs straightening or the hinges need replacing along with the rollers, which happens more often on hardware from the early 1970s than on a door installed in the last twenty years.
We come out from Seattle for these calls, so we plan the visit to do everything the door needs in one trip rather than splitting it. If we get up on the ladder and find the rollers are the least of the problem, we'll say so before we start pulling anything apart, not after.

Questions, answered
Are the rollers on my garage door original to the house?
If your house on Mercer Island was built around the early 1970s and nobody's mentioned garage door work being done, there's a real chance yes. Steel rollers from that era were built to last, but fifty years of Pacific Northwest damp without lubrication or replacement is well past their working life, even if the door still moves.
Do you replace just the rollers or the whole door?
Just the rollers, if that's genuinely all that's worn. We check the track and hinges while we're up there because on a house this age they're often stressed too, but we won't push a full door replacement on you when a roller set and maybe some track straightening solves the actual problem.
Why does the door grind at the same spot every time?
That usually means one roller has a dry or corroded bearing and is riding flat instead of turning, hitting the same worn patch of track on every cycle. It's one of the clearest signs a roller has failed rather than the opener or the spring.
Can I just buy new rollers and swap them myself?
You can, and it's a reasonable DIY job on newer hardware. On original 1973-era brackets, though, stem length and hole sizing sometimes don't match what's sold today, and top rollers sit under spring tension, if you're not sure, that's the point to call rather than force it.
