What a new garage door costs in Port St. Lucie, from a budget steel door to an impact-rated one
A new two-car door installed on the Treasure Coast runs from about $1,500 for a single-layer wind-rated steel door to $8,500 and beyond for full-view aluminum and glass, with most Port St. Lucie homeowners landing between $1,900 and $3,800 for an insulated steel door rated to their design pressure. The impact upgrade, the permit and the opener are the lines that move the total.
Every number here assumes a permitted installation: a door with a Florida Product Approval, specified to the design pressure the Florida Building Code requires for your opening, installed with the struts and brackets its rating calls for, inspected, and left with the design-pressure label on an end stile where an insurer or inspector can read it. A quote that is $600 cheaper and skips those is not the same product.

What moves the number
Insulation. A three-layer door with foam between two steel skins is quieter, stiffer, and keeps a west-facing garage ten degrees cooler in August. The stiffness also matters in wind. Windows. A row of windows adds $200 to $600 in plain glass and $400 to $1,200 in impact glass. The wind rating. Every new door here must meet a design pressure, but an exposed lot near open water needs a higher one, which means more struts and a heavier door. Impact rating. A door tested against the large-missile standard costs roughly $1,500 to $4,000 more than a wind-rated door of the same style, and brings the strongest insurance position. Size. An 18-foot or 8-foot-tall door adds 10 to 25 percent. The opener. If the existing opener is under ten years old and has working safety eyes it can usually stay; the technician will say.
What should be on the quote
The door's manufacturer, model, gauge and insulation value. The design pressure it is rated to and its Florida Product Approval number. The struts, brackets and hinges included for that rating. The permit and inspection as a separate line. The association submittal if one applies. The opener, if any, by model, with battery backup stated. Removal and haul-away of the old door. The warranty terms for the door, the hardware and the installation. A quote missing the design pressure or the product approval is not a quote for a permitted door.
Help with the cost
Under the My Safe Florida Home program, a rated replacement door is listed opening protection and the state matches two dollars for each of yours up to $10,000 when the program is funded and the home qualifies. A new rated door also earns an opening-protection credit on a wind mitigation inspection. Financing with fixed monthly payments is available through the installing contractor. All three are covered in paying for the work.
Questions on this subject
How long from quote to installed door?
Stock doors in standard colors are usually installed within one to two weeks of the permit being issued. Custom colors, carriage-house styles, impact doors and full-view glass are factory orders of four to eight weeks. The permit itself takes a few days to two weeks depending on the jurisdiction.
Do I have to replace the opener with the door?
Not if it is under about ten years old, has working photo-eyes and lifts the new door's weight. A heavier insulated door on a tired chain-drive from 2004 will finish the opener off, so the technician checks it and tells you.
Can I keep the old track?
No. Track, rollers, hinges, springs and brackets come with the new door and are part of its rating. Reusing old track voids the product approval.
Is a two-car door cheaper than two single doors?
Yes, by roughly $500 to $900, and it needs only one opener. If the center post exists for structural reasons, though, it stays.
Why is the quote higher near the water?
A higher design pressure means more horizontal struts and heavier hardware, and galvanized springs and cables are recommended. The door itself is otherwise the same model.
