Wixom's median household income sits at $68,319, noticeably below the $90,077 median across the wider Novi service area, and that gap shows up in the kind of repair call we get here: more requests for a straight spring swap, fewer for a full door-and-opener replacement bundled in. A single torsion spring replacement on a standard double door is the most common job. If both springs are original to a mid-80s install and one has gone, we'll tell you plainly when it makes sense to replace the pair rather than just the broken one - springs installed as a set wear at roughly the same rate, and a 40-year-old second spring left in place is usually a second call waiting to happen. We price the job itself, not a travel charge for the four miles over from Novi.
