We had a great experience using FF Builders. Their team communicated clearly throughout the length of our project. We never had to worry about a single detail. I would highly recommend using them for your project.

Impact and hurricane windows and doors installed by a Florida certified general contractor. Miami-Dade NOA approved products, the permit pulled in our name, and the inspection closed out, so the work counts when the insurance company asks.
We got your request and will call you back shortly (Mon–Fri, 8am–6pm ET).

The short version
Miami-Dade and Broward are the only High Velocity Hurricane Zone in the United States. A window sold anywhere else in Florida cannot legally go in here unless the product carries a Miami-Dade Notice of Acceptance, and getting one means the unit survived a nine-pound two-by-four fired at it, followed by nine thousand cycles of pressure.
Which is why the cheapest quote is usually the one that costs the most. A window without an NOA fails inspection, and an installation without a permit does not exist as far as your insurance carrier is concerned. We pull the permit in our own name and close the inspection out, so the paperwork holds up the day you need it.
Why people actually buy them
Almost everyone calls us about the hurricane. What surprises people is everything the windows do during the other eleven months of the year.

How it goes in
There are two ways to replace a window here. The fast one leaves the old frame in the wall and sets the new unit inside it. It is cheaper, it is quicker, and the anchoring does not meet the product approval, which means the installation will not pass a wind mitigation inspection and the insurance credit never comes.
We do full-frame replacement: the old unit and its frame come out down to the structural opening, and the new one is anchored to the block per the NOA. It costs more and takes longer. It is also the only version that counts.
How it works
We tell you the real timeline at the estimate, including the parts nobody controls. Impact windows are built to your openings, so most of the calendar is manufacturing and permitting, not installation.

What we install
The doors matter more than most people expect. A sliding glass door is the largest opening in almost every South Florida house, which makes it the weakest point of the envelope and the most expensive line on the estimate. An impact door is not a regular door with thicker glass: the frame, the track, the hinges and the locking hardware are all part of what the approval covers.
Single hung, horizontal roller, casement, awning, picture and fixed. All carrying a Miami-Dade NOA that covers your design pressure, which changes with how high the opening sits and how exposed the wall is.
The largest opening in most South Florida houses and the one that decides whether the envelope holds. Two, three and four panel, with pocket and stacking configurations.
Impact-rated swing doors with the same laminated glass and the reinforced frame and hardware the approval requires. A beautiful door with an unrated frame protects nothing.
Removing the old frame down to the opening rather than setting a new window inside the old one. It costs more and it is the only way the anchoring meets the approval.
When the new opening is wider than the old one, that is a beam and an engineer, not a window job. We handle both, which most window companies cannot.
The NOA package, the permit application, the inspection and the closeout. This is the part that makes the insurance credit real and it is where most cheap installs fall apart.
What it costs
Nobody can price impact windows over the phone, because the number depends on things you cannot see from the street. Four things move it, and glass is only one of them.
We measure at the house, put the model, the approval number and the price in writing, and what is on the signed proposal is what you pay. If your budget only covers part of the house, we will tell you which openings to do first, which is almost always the ones facing the water and the largest slider.
Before you sign anything
It depends on the size and the design pressure of each opening, not on the square footage of the house, which is why an honest number requires measuring. What we can tell you up front is where the money goes: the sliding glass door is usually the single most expensive opening in the house, and a second-floor window facing open water costs more than the same window on a protected wall. We measure, put the model and the approval number in writing, and hold that price.
They can, and it is one of the main reasons people buy them. Florida law requires carriers to give a wind mitigation discount for approved opening protection. The catch is that the credit is based on a wind mitigation inspection, and that inspection looks for a permitted, inspected installation with approved products. An installation done without a permit typically earns nothing, no matter how good the window is.
A Notice of Acceptance is Miami-Dade County certifying that a specific product passed the High Velocity Hurricane Zone test: a nine-pound two-by-four fired at the glass, then thousands of pressure cycles. Miami-Dade and Broward are the only HVHZ in the country, and a product without an NOA covering your conditions will not pass inspection here even if it is sold as impact rated elsewhere.
Plan on three to five months from signature to closed permit. Permitting runs two to six weeks depending on the city, and a condo association adds to that. Manufacturing runs eight to fourteen weeks because the units are built to your openings. The installation itself is usually a few days. Anyone promising the whole job in three weeks is either holding stock sizes or skipping the permit.
Yes, and plenty of people do it in phases. Be aware of the tradeoff: the insurance credit for opening protection generally requires every opening in the house to be protected, so a partial job gets you the storm protection, the quiet and the comfort, but usually not the premium discount. If the budget is the constraint, we start with the water-facing side and the largest slider.
No. Approved impact and hurricane windows are opening protection on their own, which is the whole point. What you lose is the annual ritual of putting panels up and the storage they take, and what you gain is protection that works when the storm arrives at 2am while you are out of town.
In the HVHZ the practical answer is aluminum, because that is what most approvals at the pressures we need are built around and because it holds a larger span of glass. Vinyl exists in fewer approvals here. We pick the frame from what the approval allows for your openings, not from a preference.
Also from us
Permits pulled in our name, every trade sequenced and the inspections closed out. One number to call when the job is bigger than the windows.
The house emptied and put back: layout, kitchen, baths, floors and finish, on one contract and one schedule.
Cabinets, stone and the electrical and plumbing that have to move when the layout changes. Permitted and inspected.
Waterproofing done right, tile set level, and the plumbing that decides whether it lasts fifteen years or two.
Large-format porcelain, marble and travertine, measured at your house before anyone writes a number.
Interior and exterior finish, wall texture and the prep that decides how a coat ages in this climate.
Load-bearing walls, steel and LVL beams, footings, framing and roof trusses. Engineered, permitted and inspected, because this is the part nobody redoes cheaply.
Marble, travertine and natural stone on floors, walls and countertops. Slabs picked at the yard and cut to the room, not ordered from a catalog.
Custom cabinetry, closets and built-ins, trim, crown molding and wood ceilings, built to the room instead of bought to fit it.
Free estimate
We measure every opening at your house, check what the approval requires for your design pressure, and put the model and the price in writing. No pressure, no obligation.
