The Symptom
Most houses in Kensington went up around 1962, square in the middle of the 1938-1986 build window that covers this whole service area. Doors from that era shipped with steel rollers riding on narrower track than what gets installed today, and after sixty-some years those rollers are usually the original set or a cheap replacement from a prior owner. You'll hear it before you see it: a grinding or popping sound as the door travels, worse at the top of the track where the curve starts. Some owners feel the door jump or shudder right as it clears the opening. That jump is the roller stem working loose in a dry or worn bearing, or the roller wheel itself chipped and no longer round. Left alone, a bad roller eventually jumps the track entirely, which can bend the track or crack a panel. On the older, narrower track common to houses this age, a worn roller has less room to wander before it comes off, so the symptom tends to show up faster here than on newer construction with wider rail.
What It Costs
We don't post a flat number for roller jobs because the spread depends on how many rollers need swapping and whether the track took any damage from a roller that already jumped. A full set replacement on a two-car door costs more than a single-side repair, and if the track is bent you're paying for straightening or a track section on top of the rollers. We quote on site once we've looked at the door, not over the phone. What we can tell you up front: sealed nylon rollers cost more per unit than steel, but they run quieter and don't need the lubrication steel rollers do, so for a door you're keeping another decade or two, it's usually the better spend.
What Is on the Truck
We carry both steel and sealed nylon rollers in the stem lengths that fit the narrower track still common on Kensington's 1960s-era doors, along with short sections of standard track for when a jumped roller has bent the rail beyond straightening. What we don't carry is custom or oversized track - if a door has been modified from its original hardware in a way that needs a nonstandard part, that's a special-order item and we'll tell you the lead time instead of guessing. Our limitation here is honest: we fix what's on the truck or what we can get fast, not what we'd need to special-order a week out.
How to Book
Bristol Garage Door Pros covers Kensington from our Bristol shop, about 10 miles out. Tell us the symptom - grinding, a door that jumps near the top of the track, a roller you can see is chipped - and we'll bring the roller stock and track stock that matches what's typically installed on a house built around the early 1960s. See our Kensington service page for the rest of what we cover in town, or the roller replacement page for Bristol for the general rundown on this repair.
