We don't post a flat number here because spring size, door weight, and whether one or both springs need replacing all move the price, and quoting a figure without seeing the door does nobody any favors. What we can say is that a single-spring failure on a standard double door is a different job than a two-spring replacement on a heavier insulated door, and the original hardware on a 2002 build is a known, standard size - not a custom or obsolete spec, which keeps parts cost predictable once we're on site.
Income levels in the broader Mission Viejo service area run well above Lake Elsinore's own median, and we price the job the same regardless of which side of that gap a house sits on - the spring size and door weight set the cost, not the ZIP code.
