How much does a garage door spring replacement cost in Los Angeles?

A single torsion spring replacement in the Los Angeles area typically costs $175–$350. A matched pair of springs on a double garage door runs $250–$500. High-cycle springs rated for 50,000+ cycles (ideal for homeowners who use their garage as a primary entry point multiple times daily) cost $300–$600 but last 2–3x as long as standard springs and are worth the premium in LA's mild climate where garages are used year-round.

Is a permit required for garage door replacement in Los Angeles?

A permit from the [LA Department of Building and Safety (LADBS)](https://ladbs.org/) is required if the garage door replacement involves structural or framing changes, or if the new door installation is part of an ADU or garage conversion project. A simple like-for-like door replacement on an existing opening typically does not require a separate permit, but must still be performed by a licensed CSLB contractor (Class B, C-28, or D-28) when the job total exceeds $500.

How do I know if my garage door has seismic bracing?

Look at the back of each door panel — seismic bracing struts are horizontal metal bars (typically galvanized steel, 1–2 inches wide) that span the full width of each panel section. If your panels are bare or have only decorative hardware, you likely don't have seismic bracing. This is common on older doors installed before 2000 in the City of LA. A licensed garage door technician can assess your door and install struts in 1–2 hours ($100–$250) — a sound investment given LA's seismic activity.

My garage door opened fine this morning and now won't move at all. What happened?

The most common cause of a suddenly inoperable garage door is a broken torsion spring. Torsion springs have a finite cycle life (typically 10,000–25,000 open/close cycles for standard springs) and often break without warning. When a spring breaks, the opener motor can't lift the door's weight and shuts off. You may hear a loud bang from the garage. Do not attempt to operate a garage door with a broken spring — the cable tension is unpredictable. Call a licensed LA garage door technician. This is a same-day repair from most companies.

How do I find a licensed garage door repair company in Los Angeles?

Verify any contractor through the [CSLB license lookup](https://www.cslb.ca.gov/OnlineServices/CheckLicense/ContractorLicense.aspx). Look for contractors with an active C-28 (Lock and Security Equipment) or D-28 (Doors, Gates, and Activating Devices) license. The [International Door Association (IDA)](https://www.doors.org/) maintains a directory of member companies with professional standards. In LA, most reputable garage door companies can provide same-day or next-day service for broken springs — beware companies quoting unusually low prices, which is common for bait-and-switch operations that charge excessive add-ons after arrival.
