Garage door installation, replacement, and repair in the South Bay, Los Angeles. Wind-rated panels, smart openers, and spring service. Paragon Home Services serves Redondo Beach, Torrance, Manhattan Beach, and all South Bay cities.
The garage door is the largest moving object in your home and the single most-used entry point. Paragon installs sectional garage doors, replaces broken springs and cables, and integrates smart openers (myQ, Ratgdo, Apple Home) — sized correctly for the actual door weight and specified for coastal conditions. We service same-week on most repairs and stock common spring sizes.
II.WHY IT MATTERS
What Most Homeowners Don't Know About Garage Doors
Spring Sizing Is Critical
Torsion springs are sized to the exact weight of the door. National chains often install a single 'standard' spring regardless of the actual door, which leads to premature failure, opener burnout, and an unbalanced door. We weigh the door and size the spring to the documented cycle life — typically 20,000+ cycles for residential.
Coastal Hardware Matters
Standard galvanized hinges, rollers, and tracks corrode in salt air. For homes within the coastal strip, we specify stainless or zinc-coated hardware and nylon-clad rollers — the door operates more quietly and the hardware lasts the life of the door.
Smart Opener Integration
Modern smart openers integrate with Apple Home, Google Home, and most security platforms — letting you check status, receive open-too-long alerts, and grant time-limited access. We install LiftMaster and Genie units with the integration of your choice and document the setup.
III.PROCESS
Our Garage Door Process
01On-site assessment — we measure the opening, weigh the existing door if applicable, inspect spring and track condition, and walk through opener and panel options.
02Written proposal — door spec, hardware spec, opener model, and fixed price.
03Old door removal and disposal — careful demo to avoid damaging the wall framing or stucco return.
04New door installation — track alignment, panel installation, hinge installation, and torsion-spring sizing to the actual door weight.
05Opener installation and integration — wired to dedicated circuit, programmed to remotes/smart-home platform, safety reverse tested.
06Final balance and walkthrough — we verify the door is correctly balanced (sits at any height with the opener disconnected), test all safety features, and document the warranty.

Glass and aluminum modern garage doors
Torsion spring replacement (sized to actual door weight)
My spring just snapped — can I still open the door?
Don't try. A door with a broken torsion spring weighs 150–250 pounds with no counterbalance. Forcing the opener to lift it burns out the motor and bends the panels. Call us — most spring replacements are completed same-week and many same-day.
Do I need a battery backup on my opener?
Yes, if you're installing or replacing an opener in California. SB 969 requires battery backup on residential garage door openers installed since 2019. We include code-compliant backup on every opener install.
How long should a garage door last?
A quality steel sectional door with proper hardware lasts 25–35 years. Springs are wear items rated by cycle count — a 20,000-cycle spring lasts 7–10 years for a typical household. Coastal hardware corrosion is the most common reason for early door replacement, which is why we spec stainless rollers and hinges in the coastal strip.
Can you make my old opener smart without replacing it?
Often, yes. Devices like Ratgdo and LiftMaster's myQ retrofit kit add smart-home integration to most openers built after 1993. We install and configure these for around the cost of a service call — no new opener needed.

Sectional garage door replacement, opener installation, spring and cable service, and smart-home integration.
The Paragon Difference
We size springs to the actual door weight and spec wind-rated panels for coastal homes — most national chains install one-size-fits-all and you pay for it in 18 months.
