We're not going to put a number on this page that we can't back up, so there isn't a flat price listed here. What drives the cost on a Sugar Hill job is usually how many rollers need replacing (a full set of 10 on a double door versus a handful that are just starting to go), and whether you want sealed-bearing steel rollers or nylon.
Homes built around 2002, which describes a good share of Sugar Hill's housing, often still have the builder-grade rollers that came with the door new. Those were never top-tier parts, so when one roller on a track has worn out, the rest on that same track are usually close behind it, even if they're not making noise yet. That's worth knowing before you pay for one roller and have to call back in six months for the next one.
We'll give you the number for your door and your rollers when we're there and can see the wear, not before.
