Garage Door Replacement in Ann Arbor, MI Single Panels and Full Doors

One section, or all of them

A single caved-in section can often be swapped by itself, and when that works it is the cheaper road by a wide margin. Two things decide whether it works. First, whether the manufacturer still produces your panel: doors past roughly fifteen years frequently have no matching section in production, and hunting a discontinued profile in the right color can cost more than the section is worth. Second, how far the finish has drifted, because a door that has faced south through fifteen Michigan winters has chalked and a factory-fresh section beside it reads as a patch. On a bottom section that is usually fine; at eye level it rarely is.

Historic review comes before the order, not after

Ann Arbor has fifteen local historic districts, Old West Side and Old Fourth Ward among them, and the Old Fourth Ward district was adopted back in 1983 with its survey updated in 2024. The city states that all exterior work in a historic district is regulated by the Historic District Commission and needs an application and an approved Certificate of Appropriateness. Replacing a broken spring or a set of rollers on the door you already own is hardware service. Changing what the garage looks like from the street is a design decision, and in those districts it is reviewed. Confirm the property's district status with planning staff before choosing a panel style, a window layout or a color, because a deposit placed on a door that will not pass review is money and weeks gone.

Permits and the inspection calendar

Rehanging a door, replacing springs, cables, rollers or an opener head generally sits outside the permit process. Widening the opening, altering the header or running a new circuit does not. Ann Arbor prices a residential building permit from estimated project cost, with the first tier at $100 for work up to $1,000 including one rough and one final inspection, plus a nonrefundable $15 base application fee on every permit and $35 for each additional inspection. Whoever prices the job should be able to name the filer, the filing cost, and the week an inspector is likely to show up.

Measuring is not a formality

Four dimensions get taken before a door is ordered: opening width and height, headroom above the header, sideroom on each jamb, and backroom into the garage. Detached garages behind the older streets routinely lack the headroom a standard torsion assembly needs, which calls for a low-clearance track kit and a repositioned shaft, and finding that out on installation morning costs a day. The condition of the jambs and slab matters just as much, because a garage that has settled will fight a square door forever.

What is worth specifying in this climate

Steel gauge comes first, because thinner skins dent from a bumper, a bike or a shovel handle, and a woodgrain or textured finish hides light bruising better than a flat smooth panel. Struts, the horizontal braces across the back of each section, keep a wide door flat under wind load and are the first item a bargain quote quietly drops. Ask about the bottom seal too, since a fresh flexible seal on an uneven slab is what keeps meltwater and salt off the new hardware. Nylon rollers with sealed bearings run quieter than the builder-grade steel ones that came with most doors.

A new door needs its own springs

This is the line that gets skipped. The spring on the shaft now was wound to counterbalance the door being thrown away. An insulated replacement usually weighs more, and hanging it on the old spring leaves the door heavy, the opener straining, and the spring cycling outside what it was sized for. New springs specified to the new door's measured weight, matched drums and fresh cables belong in the quote as line items you can read.
