That bang wasn't thunder — leave the door down — across Mount Pleasant, Charleston, Daniel Island, Isle of Palms, Sullivan's Island, North Charleston, James Island, Goose Creek.
A garage door spring goes out with a crack loud enough to bring the neighbors onto the porch — one sharp report, then a door the opener cannot lift and a car pinned in the garage. Leave it down and call: a wound spring holds real stored energy, and this is the repair that fills urgent-care waiting rooms with weekend DIYers.
We size replacements from the door itself — measured weight, wire gauge, coil length and inside diameter — because this market swings from light steel doors in the newer subdivisions to heavy wind-rated and custom carriage doors in the Old Village, I'On and out on the islands, and a chart guess fails exactly where doors cost the most. Coated high-cycle springs, correct turn counts, tested until the door floats level at half-open.
Salt air is a spring's patient enemy — it rides the sea breeze over the marsh, settles into the coils, pits the wire, and quietly subtracts thousands of cycles from the rating on the box. Add a garage that steams like a greenhouse from May through September, and springs east of the Cooper retire early and loudly. Coated, high-cycle pairs with honest headroom are how we take your door out of that lottery.
True door weight, wire size, length and inside diameter — insulation and hurricane bracing included in the math.
The correct spring set in one approved number before anything unwinds.
Winding bars, correct turns, matched coated pair — by the book, every time.
The door floats at half-open or we keep working — then full opener cycles.
