Fontana, CA · Garage Door Service
Fontana homes built between 1958 and 2007 often need garage door panel replacement after dents, rust, or warped sections from summer heat. See parts and cost
We stock steel and aluminum panel sections in the sizes that match the door styles common across this service area - narrow raised-panel, flush, and short-panel designs, along with the end stiles, hinges, and struts that bolt them together. Most of the doors we open up here run on hardware from the era when this housing stock went up, so we carry the older hinge spacing and roller sizes that newer doors don't use anymore. When a panel is fully discontinued, we look for a compatible width and matching finish rather than forcing a mismatched section onto the door. That's not always possible. Some early builder-grade doors used panel profiles that no longer exist in any supplier's catalog, and no amount of searching turns one up. In those cases we tell the owner straight: a single-panel swap isn't on the table, and the choice becomes matching color and texture as closely as we can, or replacing the full door. We don't carry every obsolete profile from every manufacturer that ever sold in this area - nobody does - but we carry the common ones, and we'll say so upfront if yours isn't one of them.
Panel replacement cost swings on a few things: how many sections need replacing, whether the panel is insulated or plain steel, whether the color and texture have to match an existing door exactly, and whether the profile is still made or has to be sourced as a close match. A single bottom panel on a plain steel door costs less to source and fit than a full-width insulated panel with a window cutout. Wider doors, the kind common on two-car garages across this service area, need a wider panel, which usually costs more than the same repair on a single door. We don't quote a flat number here because the honest answer depends on what's actually wrong and what the door is made of - that's a conversation, not a price list. One thing worth knowing before you call: if two or more panels are damaged, or if the panel style is fully discontinued, the labor and parts cost of chasing a match can run close to what a new door costs. At that point we'll tell you replacement is the better use of your money, even though a panel swap is the smaller job for us to book.
Most houses in this service area were built between 1958 and 2007, with the median landing around 1978, and that matters here because the panel gauges and hinge spacing from that stretch of decades don't match what doors ship with today. A door installed in the 1960s or 70s carries thinner steel than a modern panel, and thinner steel dents easier and rusts faster once the paint seal at the bottom edge wears through. Fontana sits in a moderate heat band, and that steady heat cycle - hot days, cooler nights, repeated - works on steel panels over years, loosening the seams between sections and warping the ones that catch the most direct sun. That's why the bowed or buckled panel is almost always on the same side of the door, not random. Across the 22 named areas in this service area, the same builder-era stock shows up house after house, which is why panel damage here tends to follow a pattern instead of looking like one-off bad luck. It's less about any single storm or accident and more about steel that's been expanding and contracting on the same door for forty or fifty years.
The most common call is a dented or bowed bottom panel - usually from a bumper tap or a stray basketball, but sometimes just from the door being backed into once too often. Close behind that is rust starting at the bottom edge where the paint seal has worn through and water sits after it rains. A warped mid-panel shows up as a door that binds partway through its travel, or rollers that pop out of the track on one side because the panel isn't sitting flat anymore. Sometimes the symptom isn't damage at all - it's daylight showing through a gap where a panel has pulled away from the one next to it, usually because the hinge holes have worn oval over the years. If you're seeing a panel that's cracked straight through rather than just dented, that's usually not a repair - it's a sign the steel has fatigued and the section needs to come off the door for good. We'll tell you which one you're looking at before we quote anything.
Sometimes. If the panel width and profile are still made, or close enough in a compatible width, we can fit a matching section. Older builder-grade doors from this area sometimes used profiles that are fully discontinued, and in that case there's no exact match to source - the choice becomes a close match or a full door replacement.
One panel is almost always cheaper if the rest of the door is sound and the panel is still available. Once two or more panels are damaged, or the style is discontinued and needs custom sourcing, the labor and parts cost can climb close to a new door, and we'll tell you when that's the case.
Water sits at the bottom edge after rain, and once the factory paint seal wears through - which happens faster on older, thinner steel - rust starts there before anywhere else on the door. It's the lowest point on the panel and the one that stays damp longest.
