Foam core separation
That foam bonds to the steel. Once one panel takes a hit - a trailer backing in wrong, a basketball, corrosion eating through from the inside - the skin can separate from the core even if the dent itself looks minor.
Juno Beach, Jupiter
Panel replacement for Juno Beach homes built around 1989 - steel doors with thin-gauge sections that dent, rust at the bottom, and separate at the foam core.
DIY or pro
The fault we see most in Juno Beach isn't a broken spring - it's a single damaged panel on a door that's otherwise fine. Most of these doors went up around 1989, the median build year for homes in this stretch, which puts them squarely in the era of thin-gauge steel sectional doors with a foam core sandwiched between two skins.
That foam bonds to the steel. Once one panel takes a hit - a trailer backing in wrong, a basketball, corrosion eating through from the inside - the skin can separate from the core even if the dent itself looks minor.
Pulling and swapping a single panel yourself sounds simple until you're matching a 35-year-old color and rib profile to a door nobody still makes exactly that way. We don't carry every discontinued panel style on the truck, and ordering a close match can take longer than homeowners expect.
If the hinge holes don't line up with a reasonable substitute, you're better off asking which panels actually need replacing versus which ones you could leave. That's not us being cautious for the sake of it - matching older steel is genuinely slower than people think, and we'd rather tell you that up front than have you tear into the door and find out mid-job.
Pricing
We don't post a flat price for panel replacement here because it depends on what's actually wrong - one dented panel versus a full section with rot at the bottom track, a standard steel profile versus something closer to a custom order. What we can say is that Juno Beach's median household income sits at $65,203, noticeably below the $86,562 median across the broader service area, and that's part of why we try to steer people toward a single-panel fix instead of a full door replacement whenever the rest of the door is sound. With about 2,310 households in Juno Beach, we're not dealing with a huge, uniform tract of identical doors - styles and conditions vary house to house, which is exactly why we price after we've looked at the actual panel, not off a list.
Booking
We run out of Jupiter, about 5 miles north, and Juno Beach is a regular stop on that route rather than a special trip.
When you call, tell us the door's approximate age - if it lines up with the 1989 median for the area, say so, because it changes what panel stock we bring. We'll also ask whether the damage is cosmetic (a dent you can live with for now) or structural (a crack running through the panel, a seam pulling apart), since that affects whether we bring a replacement section on the first visit or need to order one first.
We don't keep a depot in Juno Beach itself, so anything outside common panel sizes gets ordered before the job, not during it. That's worth knowing before you schedule - it saves a second trip.
Warning signs
On a door from the late 1980s or early 1990s, the panel problems tend to look the same: rust blooming along the bottom section where water sits after rain, a dent that's gone from a cosmetic dimple to a crease that's pulling the panel out of true, or a section where the outer skin has started to lift away from the foam underneath - you can sometimes feel it flex under light pressure where a sound panel wouldn't. The mild, temperate climate here means you're not dealing with freeze-thaw cracking the way colder regions do, so when a panel fails in Juno Beach it's almost always mechanical damage or slow corrosion, not weather fatigue from cold.
If the track is bent along with the panel, or the door binds when it opens, that's no longer a panel-only fix - the track or rollers need attention too, and we'll say so rather than replace a panel that won't solve the actual problem.
Questions
We'll try to match the steel gauge and rib profile as closely as the manufacturer still offers, but on a door built around the area's 1989 median, an exact color or texture match isn't guaranteed. Sometimes the better call is replacing the opposing panel too, so any slight mismatch is symmetrical rather than obvious on one side only.
If the track is straight, the door opens and closes evenly, and the damage is isolated to one section, a panel swap usually makes sense. If the frame is racked, multiple panels are rusted, or the door binds when moving, replacing the whole door is often less expensive than chasing repairs piece by piece.
Not for every style. Juno Beach has roughly 2,310 households and a real mix of door ages and brands, so for panels matching 1980s and 90s steel doors we often need to order the exact match rather than pull one off the truck.
On foam-core steel panels from this era, the outer skin is bonded to the foam. A dent can crease that bond even when the surface damage looks small, which lets moisture in behind the steel. That's part of why we check behind a dent before quoting just a cosmetic fix.
