A homeowner's guide to garage door replacement in the Triangle

What a new garage door and opener cost, what North Carolina's building code says about garage doors and wind, when Raleigh, Durham, Cary and Chapel Hill want a permit or a licensed electrician, and the federal safety rules every opener must meet. Every rule and price links to the page it came from.

What a new garage door costs

HomeGuide puts a single garage door at $700 to $2,700 installed, a double door at $1,000 to $3,500, and a three-car set of one single and one double at $1,700 to $6,200 (HomeGuide). HomeAdvisor says most replacements run $754 to $1,707, with an average of $1,231 (HomeAdvisor). Its page was updated in June 2026, though its headline still says 2025 (HomeAdvisor).

By size, HomeAdvisor puts a one-car door at $500 to $3,000 and a two-car door at $800 to $5,000; by material, steel runs $650 to $3,200 a door and wood $900 to $4,500 (HomeAdvisor). Insulated doors add $600 to $3,000, and an opener system runs $200 to $1,300 (HomeAdvisor). If the garage has no outlet where the opener goes, HomeAdvisor puts a new circuit at $1,000 to $2,500 and an outlet at $50 to $150 (HomeAdvisor). Ask for a written quote that lists each of these parts.

Licenses: who may do this work in North Carolina

North Carolina requires a licensed general contractor only for jobs costing $40,000 or more (G.S. 87-1, NC contractor board). A garage door job comes in far below that, so North Carolina does not require a contractor license for the door installer.

The opener's wiring is different. Installing or altering electrical wiring, devices or equipment as a business is electrical contracting, and that needs a state electrical license (G.S. 87, Art. 4). If the opener needs a new outlet or circuit, ask who will do that part and for their electrical license number.

Permits in Raleigh, Durham, Cary and Chapel Hill

What state law says

State law says no building permit is needed for work costing $40,000 or less unless it touches load-bearing structures and a few other items, and it names the replacement of doors as work that does not need one (G.S. 160D-1110). Adding or changing electrical wiring, devices or equipment is not exempt, other than like-for-like replacement of devices and light fixtures (G.S. 160D-1110). So a new circuit or outlet for an opener needs an electrical permit even when the door itself does not.

Raleigh

Raleigh's permit page lists "siding, windows, doors" among alterations that require a permit but no plans, and "adding circuits or outlets" among electrical work that requires one (Raleigh residential permits). Raleigh does not say how its list fits the state exemption for replacing doors, so ask the City before the work starts.

Cary

Cary's list of work that needs no building permit covers cosmetic replacements and some fixture work, and does not name doors (Cary building permits). Cary asks anyone unsure to call its Inspections and Permits Department (Cary building permits).

Chapel Hill and Durham

Chapel Hill requires a building permit for any work with structural components (Chapel Hill permits), which would include widening a garage door opening. We did not find a Durham or Chapel Hill page that says whether a same-size garage door replacement needs a permit; ask before the work starts.

The state code on garage doors and wind

North Carolina's residential code requires garage doors to be tested to ASTM E330 or ANSI/DASMA 108 and to meet DASMA 108's acceptance criteria (NC Residential Code, ch. 6). Exterior doors must be designed to resist the code's design wind loads, and must be installed following the manufacturer's written instructions (NC Residential Code, ch. 6).

The code sets a design wind speed for each county. Wake, Durham, Orange and Chatham are not on the county list, so their design wind speed is 115 mph; Johnston and Harnett are 120 mph (NC Residential Code, ch. 3). Ask the installer which wind rating the new door carries and whether it suits your county. HomeGuide notes that hurricane-rated doors cost more in coastal areas, and tells readers to check whether local codes require them (HomeGuide).

Opener safety

Every residential garage door opener made on or after January 1, 1993 for sale in the U.S. must meet a federal safety standard (16 CFR 1211). A closing door must start to reverse within 2 seconds of hitting an obstruction, and an opener for a door that moves up and down must also meet one of three further options, such as a hold-to-close control within sight of the door or a connection for an external safety device (16 CFR 1211). The Consumer Product Safety Commission names an electric eye or a door edge sensor as such devices, and says an electric eye should sit 4 to 6 inches above the floor (CPSC).

The CPSC's advice for homeowners (CPSC):

• Repair or replace any opener that does not reverse automatically.
• Test the reverse: put a 2x4 on the floor in the door's path. If the door does not reverse when it hits the board, disengage the opener until it is adjusted, repaired or replaced.
• Inspect the door and the opener every 30 days.
• If the door is out of balance, or binds or sticks, have a professional service it.
• Mount the wall button as high as practical, out of children's reach.

Hiring: questions to ask and red flags

Get at least three written estimates and a written contract, and don't pay large amounts in advance (NC Attorney General). HomeAdvisor says new doors often come with a one-year dealer warranty on materials and labor, and some installers sell extended warranties on springs (HomeAdvisor).

Questions to ask a garage door installer

• What wind rating does the new door carry, and is it right for my county's 115 or 120 mph?
• Will you install it following the manufacturer's written instructions, and leave those instructions with me?
• Does the price include removing the old door, the opener and any permit?
• Who will wire a new outlet or circuit if the opener needs one, and what is their electrical license number?
• What warranty covers the door, the springs and your labor, and for how long?
• Will you test the opener's auto-reverse and the electric eye with me before you leave?

Red flags

• A new opener that does not reverse when it meets the 2x4 test.
• No written price, or a large cash deposit before the door is ordered.
• An installer who wants you to pull any permit yourself, which the NC Department of Justice says could be a sign the contractor isn't licensed (NC Attorney General).
