Repair or replace?
Repair usually makes sense when the damage is limited and parts are easy to get. Replacement comes up when a door keeps getting hit, parts are no longer made, it's worn out, or it no longer fits how you use the opening. The company that looks at it should explain which way it leans and why.
| Situation | Leans repair | Leans replace | Ask |
|---|---|---|---|
| One dented panel or a few bent slats | Yes | — | "Can you replace just those sections?" |
| The same door gets hit again and again | Maybe | Often | "Is there a tougher door or guard for this spot?" |
| Parts for the door are no longer made | — | Yes | "Can you still get parts for this model?" |
| The door is too slow or leaks too much air for how you use it now | — | Often | "Would a faster or insulated door fit better?" |
| The opener is old and failing | Opener only | — | "Replace just the opener, or the door too?" |
| A fire door can't get approved parts from its original maker | — | Usually | Ask about the limited labeled-retrofit exception on the fire-door page |
More on this decision: our repair-or-replace reference.
Which door fits the opening and the job?
Four door types cover most commercial openings. Each one fits a different kind of use.
| Door type | What it is | Good fit when | Page |
|---|---|---|---|
| Sectional overhead door | Panels that ride up on tracks and sit under the ceiling | Dock doors and bays with headroom; insulated options exist | Overhead repair |
| Rolling steel door | A slat curtain that coils (rolls up) into a box above the opening | Little headroom, tough use, security | Roll-up repair |
| High-speed door | A fast fabric or rigid door | Busy openings and rooms that need to hold temperature | High-speed repair |
| Rolling fire door | A rolling door built to close by itself in a fire | Openings in fire walls | Rolling fire doors |
You don't need to pick the type before calling. Describe the opening and how it's used.

Questions to ask before you sign
A new commercial door involves more than the door. These questions make the quotes easy to compare.
| Question | Why it matters |
|---|---|
| "Does this job need a permit, from which office, and who pulls it?" | Offices differ by city, and the City of Los Angeles has no Express Permit category for commercial doors (LADBS) |
| "Does the new opener need new wiring, and who does it?" | In the City of Los Angeles, "Electrical Permits are required for any electrical work" (LADBS). New circuits fall under C-10 Electrical |
| "Which CSLB license class will you use?" | Doors are C-61/D-28 (CSLB). Check it on the CSLB lookup |
| "What wind-load rating does this door need at this address, and how did you figure it?" | Door ratings depend on the building and the local code, not a rule of thumb |
| "Does this opening need a fire-rated door?" | Fire doors have their own labels and testing |
| "How long until the door arrives?" | Commercial doors are often built to order |
| "What's included — removal, haul-away, opener, wiring, controls, sensors?" | So quotes compare apples to apples |
| "Can the old door be made safe until the new one is in?" | Keeps the opening secure while you wait |
| "What warranty comes with the door and the work, and from whom?" | Each company sets its own terms |
How the installation usually goes
Every company runs its own process. A typical path looks like this:
- Look and measure. The company sees the opening, the headroom, the side room and how the door gets used.
- Written quote. Door, opener, wiring, removal and any permit — spelled out.
- Permit, if needed. From the right office for your address.
- Order and wait. Many commercial doors are made to order.
- Install. Old door out, new door in, opener and safety sensors set up.
- Inspection and hand-off. If the permit calls for one. You get the paperwork and the warranty terms.
How the call works
- Call (385) 325-7138. Describe the opening, the door you have now, and the facility address.
- Company confirms the project. If the request is shared with an independent commercial door company, it confirms whether it can take the project, the scope, the price and its own terms.
- You decide. Nothing is approved until you agree to it.
Example of what to say: "We need to replace a damaged overhead door at our shop in Torrance and want to know what's involved." That's example wording — say it your way.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.

When you're ready, make the call and describe the opening.
What does a new commercial door cost?
We can't price a new door from a web page. The price depends on the size, the door type, the opener, the wiring, access and permits. Here's what to ask before you sign.
| What moves the price | Why | Ask the company |
|---|---|---|
| Size | Bigger doors use more material and bigger parts | "Is this priced for my exact opening?" |
| Door type | Sectional, rolling, high-speed and fire doors are built differently | "Why this type for this opening?" |
| Insulation and wind rating | Higher ratings mean heavier doors | "What rating is this, and why?" |
| Opener | Heavier use needs a heavier-duty opener | "What duty rating is the opener?" |
| Wiring | New circuits add electrical work and maybe a permit | "Is wiring in the quote?" |
| Removal and haul-away | Taking out the old door takes time | "Is removal included?" |
| Permit | Some jobs need one | "Is the permit in the quote?" |
| Access | Height, lifts and a busy dock add time | "Does access change the price?" |
Know the words. A starting price is the low end before anyone sees the opening. An estimate is a best guess. A written quote is the price for a set scope — get one before you sign, and ask how changes will be approved.
Ask how your opening would be priced when you call.

Frequently asked questions
Do I need a permit to replace a commercial garage door in Los Angeles?
It depends on the job and the city. In the City of Los Angeles, LADBS has no Express Permit item for commercial doors, and any electrical work needs an electrical permit. Ask the company which office handles your address and who pulls the permit.
How long does a commercial door take to arrive?
It varies by maker, size and options. Many commercial doors are made to order. Ask for the lead time in writing, and ask how the old door will be kept safe meanwhile.
Should we replace the opener at the same time?
Often it makes sense when the opener is old or doesn't suit the new door's weight and use. Ask for the price both ways.
Can a roll-up door replace a sectional door in the same opening?
Sometimes. It depends on headroom, side room, how the door is used, and what the building allows. The company looks at the opening and explains the options.
