We're not going to list a number here, because spring cost in White House depends on door width and whether one spring or a pair needs replacing - and on a 16-foot double door, a pair is the more common job than it would be on an older single-car door. What we can say honestly: a wider door with two springs costs more than a single-spring repair on a smaller door, and that's simply physics, not upselling. With median household income here running higher than much of the surrounding area, some homeowners choose to replace both springs together even when only one has failed, since the second is usually close behind it in age. That's a judgment call we'll walk through with you on site, not one we'll make for you over the phone.
