Swapping a garage door yourself isn't like changing a flat. Torsion springs store enough force to break bones if the winding bars slip, and getting panel alignment wrong on a new door means it binds on the track for years afterward - not a one-afternoon fix.
Given Bartlett's housing age, most jobs here involve pulling out a door and opener that are original to a 1990s-era home, not retrofitting something decades older. That's a more straightforward install in some ways - standard track widths, standard headroom - but the opener wiring and safety sensor placement still need to match current code, and getting that wrong is the kind of thing that fails inspection or just quietly stops working right.
Where DIY makes sense: weatherstripping, lubricating rollers and hinges, tightening loose hardware. Where it doesn't: springs, cable, and anything involving the opener's electrical work. We're honest about that split because a homeowner who tries a spring swap solo is the call we don't want to get.
