Replace the damaged section, keep the rest
A sectional garage door is built from horizontal sections, usually four on a standard 7-foot door and five on an 8-foot door, hinged together so they can roll up around the curve of the track. When one section is damaged, the door often still works, but it looks rough, may let in cold air or water, and in some cases can bind or come off the track. If the remaining sections are in good condition, replacing only the damaged section is a smart, cost-effective repair.
We replace garage door panels throughout Waukesha, from the bottom sections that take the brunt of winter salt to middle sections dented by a car door, ball or snow blower.
Common reasons for panel replacement
- Vehicle impact, from backing into the door or pulling in too far.
- Snow blower or lawn equipment bumping the bottom section.
- Sports damage from basketballs, pucks and baseballs.
- Rusted bottom section from years of road salt and standing water.
- Rot or delamination on wood or wood-composite sections.
- Cracked section after the door came off track or was forced closed.
Can my panel be replaced?
In many cases, yes, but it depends on a few factors we check during the visit:
- Manufacturer and model. Most major brands sold in the Milwaukee area, including Clopay, Amarr, Wayne Dalton, Raynor, C.H.I. and Overhead Door, offer replacement sections for current and many recent models.
- Age of the door. Doors more than about 15 to 20 years old may have discontinued designs. When a matching section isn't available, a full door replacement may be the better option.
- Color and finish. Factory white and almond are easy to match. Other colors and woodgrain finishes may fade differently over time, so a new section can look slightly different until it weathers.
- Extent of damage. If two or more sections are damaged, the cost can approach that of a new door, and replacement usually makes more sense.
Tip: Look for a label on the inside edge of the door or on one of the end stiles. It often lists the manufacturer, model and production date, which helps us order the right section quickly. A photo of that label speeds up your quote.
Our panel replacement process
- Inspect and identify. We assess the damage, identify the door model and measure the section, and check whether the impact bent tracks, hinges or struts.
- Quote and order. You get a written price for the section and labor. Replacement sections are typically ordered from the manufacturer, which takes some time depending on the brand.
- Secure the door. If the damage makes the door unsafe or unable to close, we can secure it on the first visit so your garage is closed while the section is on order.
- Swap the section. We release spring tension where needed, remove the damaged section, transfer or replace hinges and rollers, and install the new section.
- Re-balance and test. A new section can change the door's weight slightly, so we adjust spring tension, check alignment and run full safety tests.
Bottom section replacement involves spring tension. The lift cables attach to the bottom section through brackets that are under full spring load. Replacing a bottom panel is not a safe DIY project.
Panel replacement vs. a new door
We'll always give you an honest comparison. A single section replacement often makes sense for a door that is less than about 15 years old, still in good overall condition and in a model that's still available. It makes less sense when the door is older, uninsulated and showing wear on several sections, when the color is hard to match, or when the cost is getting close to half the price of a new insulated door.
For many Waukesha homes with attached garages, especially older ranches and split-levels with thin, uninsulated doors, a damaged section can be the moment to consider an insulated replacement. A new door with polyurethane insulation and good weather seals can make the garage and the rooms next to it noticeably more comfortable in January. Visit our garage door installation page for more.
Minor dents and cosmetic damage
Not every dent needs a new section. Small dents in steel doors are mostly cosmetic and don't affect how the door works. If the section isn't creased along a hinge line, the struts aren't bent and the door runs smoothly, you may choose to leave it. However, a crease along the horizontal edge of a section, where it meets the next section, weakens the door and can cause it to buckle as it rolls around the curve. That type of damage should be repaired.
We can also add or replace reinforcing struts, especially on wide double doors, to stiffen sections and prevent sagging, which is common on older 16-foot doors and doors with heavy openers attached to the top section.
Rusty bottom sections
The bottom section of a Waukesha garage door lives a hard life. Snowmelt and salt pool against it every winter, and over time the steel can rust through along the bottom edge. Replacing the bottom section and the bottom seal retainer, then fitting a fresh weather seal, restores the door's appearance and its seal against the slab. We'll also look at the bottom brackets and cables, since the same salt that rusted the panel often corrodes them too.
Panel replacement across Waukesha
We replace garage door panels in all Waukesha neighborhoods and ZIP codes 53186, 53188 and 53189, as well as Pewaukee, Brookfield, New Berlin, Genesee and Big Bend. Call or request a quote with a photo of the damage and the door label, and we'll let you know quickly whether a matching section is available.
What affects the price of panel replacement
Several things determine the cost of replacing a garage door section:
- Which section: bottom sections include the seal retainer and bottom brackets, and require spring tension to be released.
- Door type: insulated sections, woodgrain finishes, windows and carriage overlays cost more than plain sections.
- Width: a 16-foot double door section costs more than a single-car section.
- Collateral damage: impacts often bend tracks, hinges, struts or rollers that should be replaced at the same time.
Hit the door with your car? Here's what to do
- Stop using the opener. Running a damaged door can bend it further or pull it off the track.
- Check from a safe distance. Look for rollers out of the track, a bent track or loose cables, without standing under the door.
- Take photos. Photos of the damage, the track and the door label help us quote quickly, and they're useful if you file an insurance claim.
- Call us. We'll secure the door the same day if possible, then order a matching section or discuss replacement.
Homeowners insurance sometimes covers vehicle damage to a garage door, depending on the policy and who was driving. We can provide a written estimate and photos for your claim.
Struts, reinforcement and wide doors
Double doors, especially 16- and 18-foot doors, can sag in the middle over time, particularly on older uninsulated doors or where an opener pulls on the top section. Sagging sections bend at the hinges, crack along the panel seams and eventually need replacing. Adding or replacing horizontal reinforcing struts stiffens the sections and helps prevent this. When we replace a damaged section, we check the struts on the rest of the door and recommend reinforcement where it will extend the door's life. It's an inexpensive way to protect a door you plan to keep.
Frequently asked questions
How long does it take to get a replacement panel?
It depends on the manufacturer and model. Sections are usually ordered from the factory, which can take a few weeks. If the door can't close safely in the meantime, we can secure it on the first visit.
Will the new panel match my door?
For current models in standard colors, matches are usually very close. Older doors and faded finishes may show a slight difference at first. We'll talk about the likely match before you decide.
Is it cheaper to replace one panel or the whole door?
Replacing one section is usually much less expensive. If two or more sections are damaged, or the door is old and uninsulated, a full replacement often makes more sense.
Can you replace panels on wood garage doors?
Sometimes. Some wood and composite doors offer replacement sections, while others require repair or a new door. We'll inspect the door and explain what's possible.
Does a dented panel affect how the door works?
Small dents are usually cosmetic. Creases along a section's edge, bent struts or cracked sections can cause binding, so those should be inspected.
Can you fix a dent instead of replacing the panel?
Small dents in steel can sometimes be eased, but results vary and creased steel never looks new. For noticeable damage or creases along the section edge, replacement gives the best result.
