Garage door installation in South Gate, CA typically runs $700 – $2,200 for a complete system, with most homeowners spending right around $1,200 – $1,600 for a mid-range steel door with a LiftMaster opener. For more details on pricing factors, see our Garage Door Installation cost guide. We’re Onyx Garage Door Service, and we handle the entire job: old door removal, track assembly, spring calibration, opener mounting, and a final safety check before we leave. Ruben Castillo has built this company around one principle: when a technician shows up at your home on Tweedy Boulevard or near South Gate Park, they should know your door better than you do.
That’s why we train on LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor systems specifically. No generic handyman guesses. No “we’ll see what we’re working with.” We arrive knowing the failure points, the parts, and the right way to fix or install each brand. Call (877) 588-8251 for a free estimate, and we’ll give you a written price before any work begins.
- Key takeaway: Full garage door installation in South Gate costs $700 – $2,200 depending on size, material, insulation, and opener choice.
- Key takeaway: We service all eight major residential brands, so if you have a Clopay door with a Chamberlain opener, one crew handles both.
- Key takeaway: Every installation includes removal of the old door, hardware, and opener, plus a final safety inspection.
Garage Door Replacement
Garage Door Replacement is the right move when your current door has structural damage: rotted wooden panels, rusted-through steel sections, or a track system so bent the door no longer moves smoothly even after repair. South Gate’s combination of coastal humidity and morning fog attacks untreated steel quickly, and we regularly see doors along Salt Lake Avenue and Firestone Boulevard with rust lines forming within a decade of installation. Onyx Garage Door Service replaces the full system: door panels, tracks, springs, cables, rollers, and hinges, which costs $700 – $2,200 depending on material and size.
We don’t push replacement when a repair makes more sense. If your door has one cracked panel, that’s a $250 – $500 fix, and we’ll tell you that honestly. Replacement only makes financial sense when the damage is widespread or the door is beyond its expected service life.
Full System Swap
We remove your old door, hardware, and opener in one visit, then install the new system from scratch. The process usually takes 4 – 6 hours for a standard two-car garage.
Upgrade Materials
Steel, aluminum, wood composite, and insulated options are all available. We spec the material based on your South Gate home’s exposure and how much heat your garage absorbs during July and August.
Styles & brands we work with
Garage Door Installation Service
our Garage Door Installation in Los Angeles covers everything from new construction to replacing a door that’s simply worn out. If you’re building a detached garage in the Hollydale neighborhood or finishing an ADU in South Gate, we provide the full installation package: measuring the opening, ordering the correct door, assembling tracks, mounting the opener, and calibrating the limits so the door stops precisely where it should every time. Our installation service ranges from $700 – $2,200 for the complete job, and the price is always quoted and agreed before we order any materials.
What separates us from a general contractor who “also does garage doors” is that we only do garage doors. We’re not squeezing your job between a bathroom remodel and a kitchen cabinet install. This is the entire scope of our work.
Pre-Installation Measurements
We measure headroom, side room, and backroom before recommending any door. Getting these numbers wrong means installing a door that doesn’t clear the ceiling or binds against the wall, and that’s a problem you shouldn’t discover on installation day.
Opener Integration
We install and sync the opener at the same time, whether you’re keeping your existing LiftMaster or Chamberlain unit or replacing it with a new one. One visit, one coordinated job.
Commercial Garage Door Installation
Commercial Garage Door Installation serves South Gate’s warehouses, auto shops, and industrial buildings along the I-710 corridor. These doors are larger, heavier, and run on more demanding cycles than residential doors, which means the installation standards are stricter. We install commercial sectional doors, rolling steel doors, and high-cycle spring systems, with pricing that varies significantly by door size and cycle rating. For a standard commercial door, our installation starts around $1,200 and scales up with panel height and insulation requirements.
South Gate’s industrial zone stretches from the Los Angeles River east past Garfield Avenue, and we’ve installed doors for machine shops, freight companies, and distribution centers throughout that corridor. Commercial doors fail differently than residential doors: the failure comes from cycle fatigue, not age.
High-Cycle Hardware
We spec springs rated for 50,000 cycles or more on busy loading docks, because a $25 residential spring blows out in months on a door that opens 40 times a day.
Code-Compliant Steel Doors
Many South Gate commercial buildings require fire-rated doors with specific insulation values. We order according to the building’s occupancy type and fire code, working with your building inspector’s requirements.
Garage Door Installation Contractors
Garage Door Installation Contractors are only as good as the training behind them, and that’s why Onyx Garage Door Service hires and trains specialists rather than generalists. Every technician on our crew works exclusively on garage doors, openers, and the hardware that holds them together. We don’t do windows, we don’t do plumbing, and we don’t send someone out to “figure out” your Raynor door on arrival. We do garage door work, full stop.
Ruben Castillo set this standard because he’s seen what happens when general contractors sub out garage door work to the lowest bidder: misaligned tracks, springs tensioned wrong, and doors that bind within the first year. Our installers know how to tension a torsion spring to the exact quarter-turn, and they check for balance before they call the job done.
Brand-Specific Training
Our technicians receive ongoing training on Craftsman, Raynor, LiftMaster, and Chamberlain systems, so they know the quirks of each brand. The right part matters more than the right theory.
Single-Crew Accountability
The same crew that measures your opening is the crew that installs your door. No handoffs, no phone tag, no “that was the other team’s responsibility.”
Garage Door Seal Installation
Garage Door Seal Installation replaces the bottom weather seal, side weatherstripping, and top seal that keep water, dust, and rodents out of your garage. In South Gate, the bottom seal takes a beating from rain runoff and the fine dust that blows off the Los Angeles River channel during dry months. A damaged or missing bottom seal lets that dust settle on everything in your garage, and if your garage drains into the house, it becomes an indoor air quality issue. Seal installation runs $110 – $250 depending on the length of the door and whether we’re replacing just the bottom seal or the full perimeter.
Seals wear predictably. If you run your finger along the bottom edge and feel chunks missing, or if you see daylight under the door when it’s closed, the seal needs attention now. The cost is low compared to what moisture and debris will do to a door and the stored contents of the garage over time.
Bottom Rubber Seal Replacement
We slide out the old T-style or bead-style seal and install fresh material matched to your door’s channel profile. Getting the right extrusion matters more than most people realize.
Perimeter Weatherstripping
Side and top weatherstripping keeps wind-driven rain and bugs out. South Gate’s July heat makes this especially important on the western exposure, where the afternoon sun tries to warp anything not properly sealed.
New Garage Door Installation
our Garage Door Installation in Koreatown is precisely what the phrase suggests: a brand-new door, hardware, tracks, and opener, installed from scratch with no reused components. This is the right choice for new construction, complete remodels, or when the old door is so far gone that patchwork repairs would cost more than starting fresh. The price for a complete new garage door installation in South Gate runs $700 – $2,200, and your material choice, insulation level, and opener model are the three factors that move the needle most.
We order directly from manufacturers, so you can choose the exact door you want rather than being steered toward whatever’s sitting in a distributor’s warehouse. If you want an insulated Amarr door with a Chamberlain belt-drive opener, we order it and install it. If you want a basic non-insulated steel door, we install that too, with the same standard of workmanship.
New Construction and ADUs
South Gate’s ADU boom means plenty of garages are being built alongside converted back houses. We measure the opening during framing, advise on clearance requirements, and install once the structure is ready.
Full System Replacement
This covers doors that have reached the end of their service life. We’ll inspect your existing door first and tell you straight if repair makes more sense than replacement.
Brands We Service
We work on your brand, not just our preferred one. That’s the core of how Onyx Garage Door Service operates. LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor: these eight brands cover the overwhelming majority of garage doors and openers in South Gate homes, and we’re trained and equipped to service all of them.
LiftMaster and Chamberlain openers share a lot of engineering DNA, so we diagnose both with the same depth of knowledge. We’ve worked on countless Craftsman units from the 1990s and early 2000s that are still running, and we know which replacement parts keep them alive. Raynor doors have their own track profile, and we order their specific hardware rather than forcing generic parts to fit. Whether you have a Raynor door or a Chamberlain opener or a system that combines two brands, we can handle it.

AfterSigns You Need a Pro Right Now
- Your door has visible cracks or dents in more than one panel. Once structural integrity is compromised, the door flexes under its own weight, which stresses the hinges and tracks. That flexing accelerates wear on every other component, and a single panel replacement won’t fix the underlying problem.
- The door shakes or shudders while opening and closing. This usually means a roller is binding, a track is out of alignment, or a spring is starting to fail. Each cycle makes the problem worse, and it will eventually leave the door stuck in place.
- You hear a loud bang from inside the garage. That’s almost always a torsion spring snapping under tension. The spring holds hundreds of pounds of force, and the failure can damage anything nearby, including vehicles and stored items.
- The door sits unevenly or stops a foot above the ground. Uneven seating points to cable or spring issues. A door that won’t fully close is a security problem, and it exposes your garage to weather and pests.
- Your bottom seal is cracked, flattened, or missing entirely. South Gate’s dust season runs from late summer through fall, and a broken seal means every Santa Ana wind event coats your stored items in a fine layer of grit. Water intrusion during winter rain follows the same path.
Caution: garage door springs and cables are under extreme tension. Do not attempt to adjust, remove, or replace torsion springs, extension springs, or lift cables yourself. These components can cause severe injury. We use trained professionals and specialized tools for every spring and cable job.
Our Process, Step by Step
- 1
On-site measurement and assessment. We measure the opening width, headroom, side room, and backroom. We also inspect the existing hardware, if any, to see what can be reused and what needs replacement.
- 2
Written proposal with exact pricing. You get a line-item list of everything we’re doing and the total cost, agreed before any work begins. No hidden fees, no surprise line items added after the fact.
- 3
Removal of the old door, hardware, and opener. We strip the old system down to the opening. This includes careful handling of the old torsion spring, which is unloaded safely by a trained technician.
- 4
Installation and calibration. We hang the new door, install the tracks and springs, mount the opener, and calibrate the travel limits and force settings. We test the door’s balance at multiple heights and make adjustments until it operates smoothly and quietly.
- 5
Final walkthrough and clean-up. We demonstrate the door’s operation, walk you through the opener’s features, and haul away all debris. The job site is left as clean as we found it.
How Much Does Garage Door Installation Cost in South Gate?
A typical garage door installation in South Gate runs $700 – $2,200, with the final number driven by door size, material, insulation level, and opener choice. A basic non-insulated steel door for a standard two-car garage costs $700 – $1,000. Step up to an insulated steel door with a belt-drive LiftMaster opener and you’ll land around $1,400 – $1,800. Custom wood or wood-composite doors start around $1,800 and go up from there.
What affects the price the most? The door material, whether you’re adding an opener, and whether the old system requires extra removal work. A garage with rusted-in hardware takes longer to strip than one with clean bolts. That said, our quote always reflects the actual condition of your garage, not a worst-case guess.
The best way to avoid overpaying is to get a written estimate from someone who actually looked at your opening. Photos help, but some clearance issues only show up in person. That’s why our free estimates are on-site and itemized. You’ll see the exact cost of the door, hardware, opener, labor, and removal before you commit to a single dollar. Call (877) 588-8251 to book your estimate.

We handle the full job from start to finish, leaving you with a working door and a clean job site.

Yes. Onyx Garage Door Service is trained on LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor.
