With a median household income of $52,581 in Benton City - well under the $87,022 median across the rest of the service area - most of the calls we get out here are for the roller job alone, not a bundled track-and-opener overhaul. That's a reasonable way to spend the money: rollers are a wear part, and replacing just the worn ones is usually the right fix unless the track itself is bent or the door is badly out of balance.
We don't post a flat number here because stem length, roller count, and whether the track needs adjusting all move the bill. What we can tell you is that steel rollers cost more up front than nylon but outlast them and run quieter in cold weather, so for a lot of Benton City's 1,300-odd households, the steel upgrade pays for itself over the life of the door.
