We're not listing a price here, because FACTS for this page don't include one, and a guessed number is worse than none. What we can say is how the decision usually breaks for Grantley: at a median income of $121,563, most homeowners here can cover a spring or cable repair without much deliberation, so the real question becomes repair versus replace, not repair versus doing nothing. A door built around 1961 that needs a second or third hardware fix in a few years is often past the point where another repair makes sense - the track, rollers, and panel are all aging together, and patching one piece just shifts the failure to the next one.
