Broken Spring Repair
Torsion springs on the newer doors and extension springs — fitted with the safety containment cables so many Florissant garages are missing — on the originals.
Spring repair →Florissant is one of the oldest settlements in Missouri, founded in the 1780s — but the garage doors here are pure post-war. The city went from a few thousand residents in 1950 to one of the largest in St. Louis County within twenty years, and that boom-era housing stock is what we work on every week across 63031, 63033 and 63034.
Broken springs, dead or erratic openers, frayed cables, screeching steel rollers, bent track, doors off their tracks and rusted-through bottom sections. Florissant also produces more “this is the original everything” calls than almost anywhere else we work — homes where the door, the track, the rollers, the springs and the opener all went in when the house was built and none of it has ever been serviced.
We cover the whole city: Old Town Florissant and the streets around St. Ferdinand Park and the Old St. Ferdinand Shrine, the Paddock neighborhoods, the Cross Keys area, the subdivisions off New Halls Ferry Road and Old Halls Ferry Road, Howdershell Road, Patterson Road, Charbonier Road and Shackelford, and the corridor along Lindbergh Boulevard.
Florissant’s explosive growth happened in the 1950s and 1960s, and the housing that arrived reflects exactly that moment: brick ranches, split-levels and modest two-stories, most with an attached garage sized for one car or a narrow two. That produces a very specific service profile.
Narrow openings. A great many Florissant garages have an 8'x7' or 9'x7' single opening rather than a modern 16-foot double. Doors that size are often still on extension springs — the springs stretched horizontally along the upper tracks — rather than a torsion shaft. Extension springs are perfectly workable, but each one is supposed to have a safety containment cable running through its center and anchored at both ends, so that if the spring breaks the pieces cannot fly across the garage. On Florissant houses of this era those cables are missing constantly: never fitted originally, or removed during a repair years ago and never put back. It is an inexpensive part and we install it as standard with any extension spring work. If you can see springs along the side tracks with nothing threaded through them, tell us when you call.
Original hardware, sixty years on. The track, hinges, rollers and bearing plates on an untouched Florissant garage have been through six decades of Missouri summers at seventy-degree dew points and six decades of freeze-thaw winters, in an unconditioned space, with no lubrication. Steel roller bearings grind themselves flat. Hinge pins seize. Track fasteners work loose and the track drifts out of plumb. Cable strands break one at a time at the drum until the last few let go. Most of what looks like a sudden failure in Florissant is actually the last step of a very slow one, which is why a 25-point tune-up is genuinely the highest-value thing you can buy on a house this age.
Ranches with rooms over the garage. Where the floor plan puts a bedroom or den above an attached garage — common in Florissant’s split-levels — the complaint is almost always noise. Ten sealed-bearing nylon rollers plus a real hand balance and proper lubrication is the single biggest improvement available, and it costs a fraction of a new door.
Openers older than the safety rules. If your Florissant opener is original or close to it, it predates the federal requirement that residential openers made after 1 January 1993 include photo-eye sensors and auto-reverse. No sensors means no entrapment protection at all. That one is worth acting on regardless of what else the door needs.
Lindbergh Boulevard, New Halls Ferry Road and I-270 put our trucks anywhere in Florissant quickly, and Highway 370 links us straight across to St. Charles County. Most Florissant calls placed in the morning are handled the same day; a broken spring with a car trapped inside gets priority, and after hours we run 24/7 emergency dispatch. Two-hour arrival windows, a text with the technician’s name and photo when he’s en route, and — this matters in north county — exactly the same flat rate we charge in Ladue or Chesterfield. One price book, metro-wide. No ZIP code tax, in either direction.

Spring repair →Any opener without photo-eye sensors near the floor predates the 1993 safety requirement and should be replaced. Sensors, gears and boards where repair makes sense.
Opener service →Sixty-year-old steel rollers with ground-flat bearings are the loudest thing in a Florissant split-level. Nylon rollers are the cheapest dramatic fix there is.
Rollers & track →Original cables fray strand by strand at the drum for years before they snap. Replaced in pairs with the drums re-seated and the door re-balanced.
Cable repair →Insulated steel singles sized for Florissant’s 8'x7' and 9'x7' openings, which also cuts the heat loss through an attached garage wall.
New doors →On original hardware this is the highest-value service we sell: balance, lubricate, torque the fasteners, test auto-reverse and tell you honestly what is failing next.

Prices are typical St. Louis-area ranges as of 2026 and vary by door size, spring cycle rating, hardware condition and access. Your exact price is quoted in writing before any work begins. See the full pricing page.
We also cover St. Charles and St. Peters across Highway 370, plus Creve Coeur and Chesterfield down I-270.
The City of Florissant runs its own building division and contractor registration, separate from St. Louis County, and its requirements differ from Hazelwood, Ferguson or Black Jack next door. Swapping a door and hardware into the existing opening is treated differently from altering the opening itself, and any structural change to the header or width needs a permit and an inspection. Check with Florissant’s building division before you order, or let us handle it — we’ll tell you upfront if your address needs one.
Yes, and this is a regular Florissant call. Like many north St. Louis County municipalities, Florissant requires an inspection when a property changes hands or a new tenant moves in, and garage door items — an opener that will not auto-reverse, missing or misaligned photo-eye sensors, a door that will not close and seal, damaged panels — are exactly the sort of thing that lands on the correction list. Confirm the exact items with the city inspector, then call us; sensor alignment and auto-reverse adjustment are usually a same-day fix, and we’ll give you a paid invoice describing the work for your re-inspection.
Only if the safety containment cables are missing — and on Florissant houses of this era they very often are. Those are extension springs. A cable is supposed to run through the center of each one and anchor at both ends so a broken spring cannot become a projectile. They are inexpensive, they take minutes to fit, and we install them as part of any extension spring service. If you can see springs along the upper tracks with nothing threaded through them, get it addressed.
Yes. Photo-eye sensors and auto-reverse became a federal requirement for residential openers manufactured after 1 January 1993, so a unit without them is at least three decades old and offers no entrapment protection whatsoever. Beyond the safety issue, the drive gear, capacitor and limit switches in an opener that age are all well past their design life — which is why the door bangs down or reverses at random. A modern belt drive is also far quieter under a bedroom.
We’ll show you rather than tell you. If the sections are sound and the failure is a spring, cable or roller, repair is usually the right money — a spring set costs a small fraction of a new door. If the bottom section is rusted through, the panels are delaminating or the track is corroded and out of plumb, repair money is going into a door that owes you nothing, and we will say so plainly. Our technicians are not paid on commission, so nobody here profits from steering you toward the bigger number.
We charge the same. That is deliberate. One flat-rate price book runs across the entire metro, so the identical repair costs the identical amount in Florissant, Ladue and Wentzville. No ZIP code tax, no premium for an affluent address and no discount bait for anywhere else.
Two-hour arrival windows, a written flat-rate price before we start, and a parts-and-labor warranty on the invoice.
