We don't have a fixed price to quote you here, and we'd rather say that than make one up. What we can tell you is what drives the number: how many rollers need replacing (a full set of 10 costs more than swapping the two or three that are actually bad), whether the track needs straightening or full replacement, and whether we find a bent stem or stripped bracket hiding behind the obvious complaint. Dunmore's median household income runs higher than some of the surrounding towns - around $75,632 against this area's broader median near $68,010 - which doesn't change what parts cost, but it does mean we see more owners opt for the full nylon upgrade across both doors at once rather than patching one roller at a time. That's a choice, not a requirement.
