Garage Door Panel Replacement in St. Louis, MO
One dented section does not automatically mean a new door — and it does not always mean you should keep the old one, either. We identify the manufacturer and model, check whether the section is still in production, and put both numbers in front of you so you can make the call with real information.
When a single section can be swapped
A sectional garage door is four, five or six horizontal sections joined by hinges, and any one of them can be removed and replaced. Unload the counterbalance, disconnect the hinges and roller stems above and below the damaged section, slide it out, set the new one in, re-hang the hardware and re-balance. On a well-maintained door with a currently produced panel, it is a one-visit job.
A panel swap is the right call when the rest of the door is sound, the damage is confined to one or two sections, and the section is still available in your door’s exact model, gauge, profile and color. That last part is where the honest conversation happens, because “still available” is not a given. Bottom sections are the exception — they take the most abuse, and manufacturers stock them longest, so damage down low usually has the best odds of a clean repair.
When the whole door is the better economic call
We tell you to replace the door when the math says so. A single section installed runs $350–$800. A new insulated steel single door runs $1,100–$1,900; a 16'x7' double runs $1,700–$3,200. Once you need two sections on a double door plus new hinges and a re-balance, you are frequently at 55–70 percent of a brand new door — with the old door’s remaining lifespan, hardware and insulation value.
Three situations tip the decision toward replacement even when one panel would technically work: a non-insulated single-layer pan door on an attached garage, where the R-value upgrade alone changes how the space feels; a door already past 20 years, because you will be buying springs, rollers and cables within two years anyway; and damage on a street-facing elevation where a color-matched panel is not going to look right. See new garage door installation.
Discontinued models: why matching gets hard after about ten years
Manufacturers revise their lineups constantly: profiles get restyled, steel gauges change, insulation cores switch from polystyrene to polyurethane, and model lines get retired and renamed. As a rough rule, doors under ten years old are usually matchable, ten to fifteen is a coin flip, and over fifteen is rarely matchable in the original profile.
The first thing we do is find the data label — usually a sticker inside an end section or on the bottom section near the bracket — which gives us the manufacturer, model and often the production date. If the label is gone, which happens constantly on 1990s doors in South County and North County, we measure the section height, count the ribs and photograph the embossing and stile pattern to work backward from the profile. Sometimes we find the exact match; sometimes we find a dimensionally identical section from a different maker, which works mechanically but reads slightly different in the detail. You see a photo before you commit either way.
One useful workaround: if the profile is matchable but the color is not, we can often relocate sections — putting the mismatched new panel at the top, where the header shades it and the street barely sees it, and moving an original section down into the damaged spot.
Color fade on sun-exposed doors
This is the part nobody warns homeowners about. A ten-year-old almond or sandstone door with a west or south exposure has faded, and a brand-new section in the same factory color will not match it — correct in the shade, obviously newer in afternoon sun. On white the difference is mild. On the brown, bronze and hunter green doors that are everywhere on Kirkwood and Webster Groves mid-century ranches, it can be dramatic.
The options are honest ones: live with it, which many people do on an alley-facing or side-load garage; repaint the whole door in an exterior acrylic latex formulated for steel, which unifies the color and holds five to eight years here; or replace the door. What we will not do is install a section and act surprised when you call about the color two weeks later.
Hail and storm damage: documenting it for the adjuster
St. Louis sits in a real severe-weather corridor, and hail seasons here reliably produce a wave of dented doors from Chesterfield and Ballwin out through St. Charles County. A garage door is one of the easiest claim items for an adjuster to dispute, because hail dimpling on ribbed steel is nearly invisible in a photo taken straight on.
What actually works: raking-light photographs taken at a low angle across the panel face so the dimples cast shadows; same-session photos of the roof, gutters and soft-metal test surfaces establishing a consistent hail event across the property; a close-up of the data label proving the door’s age and model; and a written, itemized estimate separating section cost, hardware, labor and re-balance rather than one lump number. We provide that as a packet you can forward to your carrier.
Two things worth knowing. Adjusters commonly approve a partial — one or two sections — when the whole door is dented, on the theory that sections are individually replaceable; if your door is discontinued, that is your strongest argument for a full replacement, and we document the discontinuation in writing. Second, some Missouri policies carry a cosmetic damage exclusion. Check your declarations page before you file.
Structural damage versus cosmetic damage
Cosmetic means the skin is dented or scratched but the section is still straight across its length, the stiles are intact, the hinges hold their fasteners and the door runs normally. You can defer that repair for as long as you are willing to look at it.
Structural means the section is bowed, creased across the face, delaminated from its insulation core, or the end stiles are bent so the rollers no longer track true. A compromised section flexes under load, which stresses the hinges above and below it and eventually tears fasteners out of the skin — that is how a dented door becomes an off-track door. A cracked wood or composite section is also structural; moisture gets into the core and the failure accelerates.
The tell we look for: run the door and watch the joint lines. If a joint opens and closes as the section passes the radius, that section is flexing and needs to come out.
What panel replacement costs in St. Louis
A single section typically runs $350–$800 installed, driven by door width, insulation type, panel style and whether the section is stocked or factory-ordered. Non-insulated single-layer steel sits at the bottom of that range; insulated steel with woodgrain embossing sits at the top; carriage-house and full-view aluminum are quoted individually. Factory orders take one to three weeks to reach the St. Louis market. Full ranges are on our pricing page.
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.
We handle section work across the metro — hail claims in Chesterfield and Ballwin, vehicle-impact repairs in St. Peters and O’Fallon, older door matching in Florissant and Webster Groves. If the damage knocked the door out of alignment, book emergency service and we secure it first.
Panel Replacement FAQs
Can you replace just one garage door panel?
Usually, yes — if the section is still in production in your door’s model, gauge, profile and color. We start by locating the data label on the inside of the door, which gives us the manufacturer and model. If the label is missing we identify the door from the panel profile and dimensions. If nothing matches, we tell you that plainly rather than installing something that will not look right.
How can I tell if my garage door section is discontinued?
Age is the fastest indicator. Under about ten years and a match is likely; over fifteen and it usually is not, because manufacturers restyle panel profiles and retire model lines. Send us a photo of the data label and a straight-on shot of the door and we will check availability with our suppliers before we schedule anything.
Will a new panel match the color of my faded door?
Not exactly, on any door with real sun exposure. A factory-new section in the original color will read brighter than a ten-year-old panel next to it — mild on white, noticeable on almond and sandstone, dramatic on brown, bronze and dark green. Options are living with it, repainting the whole door in exterior acrylic latex for steel, or replacing the door. We raise this before you approve the work, not after.
Is it cheaper to replace a panel or the whole garage door?
One section at $350–$800 is clearly cheaper than a full door at $1,100–$3,200. But once you need two sections on a double door plus hardware, you are often at well over half the cost of a new insulated door — with the old door’s remaining life and old hardware. We quote both so the comparison is on paper in front of you.
Does insurance cover hail damage to a garage door in Missouri?
Frequently, yes, under the dwelling coverage of a homeowners policy — but some policies carry a cosmetic damage exclusion that specifically limits payment for dents that do not affect function. Check your declarations page. We supply raking-light photos, an itemized estimate and written confirmation if your model is discontinued, which is often the deciding factor in getting a full door approved rather than a partial.
My door has a dent but still works fine. Do I have to fix it?
If the damage is purely cosmetic — skin dented, section still straight, hinges holding, door running true — you can defer it indefinitely. If the section is bowed or creased across its face, or you can see a joint opening and closing as the door passes the curve, that is structural. Deferring structural damage stresses hinges and eventually pulls the door off track, which costs far more than the panel.
