A door rated for your opening's design pressure, installed with the paperwork your inspector and your insurer ask for.
Installed from $2,400 one car and $3,900 two car.
We measure the opening, look up your address's design pressure and give you the price in writing. Free, no obligation.
CMC Door Service supplies and installs hurricane garage doors across Miami-Dade, Broward and Monroe County. Every hurricane rated garage door we fit is impact rated and carries a Miami-Dade Notice of Acceptance or Florida product approval for the design pressure of your opening, at the 175 mph Miami-Dade and 170 mph Broward design wind speeds. A one-car impact door starts at $2,400 installed and a two-car at $3,900.
Miami-Dade NOA approved garage doors. A door is rated in design pressure, and the door's rating has to equal or exceed the design pressure for your opening at Miami-Dade's 175 mph design wind speed. Impact-resistant and wind-load tested.
Hurricane-rated residential garage doors from Clopay, Amarr, Haas that protect your home without sacrificing style.
Hurricane-rated commercial rolling doors and sectional doors for businesses, warehouses, and storage facilities.
Design pressure is measured in pounds per square foot, and it is what a product approval is written against. Find your wind speed, your exposure and whether the house is one storey or two, and the number below is what the door has to be rated for.
A wind rated door is not simply a thicker panel. It carries horizontal steel struts across the back of each section, commercial grade track, and heavier rollers, hinges and springs sized for the load. The whole assembly is tested together, which is why swapping parts on an existing door does not make it rated.
There is nothing to bolt to the floor before a storm and nothing to store the rest of the year. You close it and you lock it.
Positive is the wind pushing the door in. Negative is it pulling the door out, and it is nearly always the bigger number. That is why a door that looks solid from the driveway can still come off its tracks: it gets sucked outward, not pushed inward.

Pounds per square foot, from a manufacturer table computed to the 5th Edition Florida Building Code (2014) and ASCE7-10, Exposure C. Permits are reviewed under the 8th Edition Florida Building Code (2023), in effect since December 31, 2023. Columns for Broward at 170 mph and Miami-Dade at 175 mph are highlighted. These are minimums, and a product approval has to meet or exceed them for your specific address. Figures from the Clopay Florida Edition WINDCODE brochure, RSDR-WCBRFL-12.
Miami-Dade and Broward require all garage doors to carry the large missile impact rating, whether the door has windows in it or not. That is stricter than most of the state and it is the single most common reason a door bought elsewhere cannot legally be installed here.
Because of the impact requirement, any windows in the door have to meet the same impact standard as the door itself. That is a different and more expensive product than the standard glazing sold elsewhere in Florida, and it is why a door catalogue's standard window options are not offered here.
A properly rated door is reinforced with horizontal struts, heavier track, and commercial-duty rollers and hardware. There is nothing to bolt to the floor before a storm and nothing to store the rest of the year. You close it and lock it.
Code is a minimum. Insurers sometimes require a higher rating than the code does, and many give a wind mitigation credit for a door that exceeds it. It is worth asking them before choosing, because the discount can outlast the difference in price.
The large missile test fires a nine pound length of two by four at the door at roughly 50 feet per second, then cycles the pressure thousands of times afterwards. A window that passes usually looks like this: the outer pane is broken right through, and the laminated interlayer still holds it in the frame so the opening never breaches.
That is the whole point of the rating. Nobody is claiming the glass survives undamaged. What matters is that the envelope of the building does.
We do this for you on the estimate, but it is worth knowing what drives the number.
From the Florida wind speed map for your address. Miami-Dade is 175 mph and Broward 170 mph for most homes.
B, C or D. Almost everywhere in Miami-Dade and Broward is Exposure C, unless you are within 600 feet of open water.
Single storey or two storey, because a taller building sees higher pressure at the same wind speed.
Those three together give the positive and negative pressure your door has to be approved for, and the product approval has to say so. The table here is a reference for finding your number. Confirm it for your own address with your building department against the code edition in force when you pull the permit.
Urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions.
Open terrain with scattered obstructions, including flat open ground and grassland. All of Miami-Dade and Broward falls here unless it meets the Exposure D definition.
Within 600 feet of the ocean or another body of water at least 5,000 feet across. Design pressures come from the building code official or DASMA TDS-155x.

Full protection for your peace of mind.
Transparent pricing, no hidden fees.
Every one of these is a code consequence rather than a sales point, and each one changes what a door costs. Worth knowing before you compare two quotes.
Miami-Dade and Broward require all garage doors to meet the large missile impact rating, whether the door has windows in it or not. That is stricter than most of Florida, and it is the commonest reason a door bought online or brought in from out of state cannot legally be fitted here.
A door's wind load rating is expressed in PSF, pounds per square foot, as a positive and a negative number. The design pressure of the door has to equal or exceed the design pressure for the opening it goes into. Your county wind speed, the exposure, the size of the opening and whether the house is one storey or two are what set that.
A door that has passed the large missile impact test is itself the protection for the opening, so it does not need an impact-resistant shutter over it. There is nothing to bolt to the floor before a storm and nothing to store the rest of the year. You close it and you lock it.
Insurers sometimes give discounts for garage doors and other exterior products that exceed what the local code requires, so installing a new garage door with the large missile impact rating may reduce your insurance premiums. Please check with your insurance agent for details.
Grant amounts and eligibility are set by the program and change between funding rounds, so we do not quote a figure here.
My Safe Florida Home is run by the State of Florida. It offers a free wind mitigation inspection and grants toward hurricane mitigation improvements, and a wind and impact rated garage door is one of the improvements it covers.
The grants are for eligible homesteaded homes, and the program sets its own rules on the home and the owner. It works in funding rounds and can stop taking applications when a round runs out.
Check whether you qualify on the program's own site before you sign for a door, because the program decides what it pays toward and when the work can start. If you are approved, we quote the door against your inspection report and supply the permit and product approval paperwork.

Miami-Dade and Broward sit in the High Velocity Hurricane Zone, the strictest wind-load region in the Florida Building Code. The ultimate design wind speed is 175 mph in Miami-Dade and 170 mph in Broward, for most residential buildings in Exposure C. Every CMC hurricane-rated door meets or exceeds local code.
Every photo in this section is our own work across Miami-Dade, Broward and Monroe County.
The doors, finishes and hardware we fit across South Florida.
Miami-Dade and Broward sit in the High Velocity Hurricane Zone, the strictest wind-load region in the Florida Building Code. New and replacement garage doors in hurricane impact zones have to carry the required approval for the wind loads at your address.
In Miami-Dade and Broward, in practice, yes. Hurricane garage door and hurricane rated garage door are what most people search for; what the code asks for is a door rated for the wind load of your opening that has also passed the large missile impact test, with a Miami-Dade NOA or a Florida product approval to prove it. A door rated for wind load only is sold elsewhere in Florida, but it cannot be permitted here, so every hurricane door we quote in the HVHZ is impact rated.
It is the largest opening in most homes. If it fails, wind gets inside and pressurises the structure, which is what lifts roofs. Reinforcing the door protects far more than the garage.
A combination of gauge and bracing (struts and bracing sized by the manufacturer for the design pressure) plus heavier tracks and hardware, and a product approval covering the design pressures for the location.
Sometimes. Retrofit bracing exists for some doors, but it does not turn an unrated door into a rated one. We will assess your door and tell you whether reinforcement or replacement is the honest answer.
Insurance companies sometimes give discounts for garage doors and other exterior building products that exceed what the local building code requires, so installing a new garage door with the large missile impact rating may reduce your insurance premiums. Many Florida insurers offer wind mitigation credits for approved opening protection, and we can provide the product documentation for your wind mitigation inspection. Please check with your insurance agent for details.
Yes. Miami-Dade and Broward require all garage doors to meet the large missile impact rating, regardless of whether the garage door has windows or not. There is no exemption for a plain solid-panel door. It is the commonest reason a door bought elsewhere in the country cannot legally be installed here.
No. A door tested and approved as resistant to large missile impact is itself the protection for that opening, so it does not need an impact-resistant shutter fitted over it. There is nothing to bolt to the floor before a storm and nothing to store the rest of the year. You close it and you lock it.
In design pressure, expressed in PSF, pounds per square foot, as a positive and a negative figure. Positive is the wind pushing the door in, negative is it pulling the door out, and the negative is usually the larger of the two. The rule is straightforward: the design pressure of the door must equal or exceed the design pressure for the garage door opening it is being installed in. Your county wind speed, the exposure category, the size of the opening and whether the house is one storey or two are what set the number for the opening.
HVHZ is the High-Velocity Hurricane Zone, which covers Miami-Dade and Broward. A door approved for it has been tested to the design wind speed for that county and has passed both the large and small missile impact tests. It is a tested certification, not a manufacturer's description.
Design wind speeds are 175 mph in Miami-Dade and 170 mph in Broward. The pressure figure in pounds per square foot that follows from that depends on the size of the opening and where it sits on the building, which is why two doors with the same rating are not always interchangeable.
A Notice of Acceptance (NOA) is issued by the Miami-Dade County Product Control Division and confirms the door has been tested and approved for the HVHZ. Every garage door installed in Miami-Dade must carry one. Every hurricane-rated door we install comes with its full NOA documentation.
The warning signs of a door that is not are visible rust or corrosion on tracks and panels, a door that rattles or shakes in moderate wind, missing or damaged weather stripping, single-layer non-reinforced panels, and windows without impact-rated glass. If any of those apply it is worth having it inspected, and the inspection is free.
Our published prices start at $2,400 installed for a one-car hurricane impact rated steel door and $3,900 for a two-car door. Insulated construction, a heavier wind rating, impact glass and carriage-house or wood-look faces take it up from there, to $6,600 for a Coachman and $9,050 for a Canyon Ridge, and higher again on the widest openings. What moves the price is the wind rating level, the insulation R-value, the material, whether you want impact glass, and any custom design work.
Clopay, Amarr, Haas Door and Raynor. All four engineer specifically for South Florida wind load requirements, and between them they cover everything from a single-car residential door to a large commercial rolling door.
CMC Door Service, a licensed garage door and commercial rolling door company based at 14252 SW 140th St Ste 108, Miami, FL 33186. We measure the opening, work out the design pressure for your address, order a door approved for it, file the permit, install it and hand you the approval paperwork. A one-car impact door starts at $2,400 installed and a two-car at $3,900. For businesses we install impact rated commercial sectional doors and wind rated rolling steel doors.
The garage door is the largest opening in most homes. If it fails, the sudden pressure change inside the building can lift the roof off and cause structural damage to the whole house. That is the reason the code treats it as seriously as it does.
The Notice of Acceptance for the door and its hardware, the permit and inspection record where the job needed one, and the manufacturer documentation for the opener. Keep all of it together, because it is what a wind mitigation inspector, an insurance adjuster and a future buyer's home inspector each ask for, and replacing an NOA years later means tracing it back through the manufacturer by model and installation date.
