Hurricane Windows Cost in South Florida: What You’ll Actually Pay Per Opening
In South Florida, hurricane windows cost $8,000-$25,000 for a typical home when fully installed, permitted, and finished. That works out to roughly $800-$1,400 per opening for impact-rated units meeting Miami-Dade and Broward’s High Velocity Hurricane Zone requirements. Call Groundwork Construction Co. of South Florida at (844) 665-0162 for a free, line-item estimate that shows exactly what’s included.
Here’s the number that catches homeowners off guard: the window itself is often only 55-65% of your total project cost. The rest is what happens after the glass arrives on the truck.
The Buck Work Nobody Warns You About
If a contractor quoted you $800 per window installed, ask what’s included after the glass hits the opening - because in a South Florida CBS home, the answer to that question is where projects go over budget.
Concrete block construction doesn’t have wood framing around window openings like you’d find in frame houses up north. You’ve got a rough block opening that needs an aluminum buck - a fabricated frame that creates the proper fastening surface and drainage plane for the impact window. Without it, you’re screwing into crumbly block and hoping the sealant holds through 180 mph gusts.
We’ve replaced windows in Coral Gables homes from the 1960s where the original jalousies were held in with nothing but plaster and optimism. The buck fabrication and installation runs $80-$150 per opening. Stucco patching and repainting the perimeter adds another layer. Permitting in most Miami-Dade and Broward municipalities runs $150-$400 per opening depending on whether your city charges flat fees or calculates by valuation. Disposal of old single-pane or jalousie units? That’s another line item that doesn’t show up in online “average cost” articles written by people who’ve never pulled a permit in Hialeah.
Raymond Estevez, our owner, grew up in Hialeah watching his uncle gut and rebuild houses on the block. He’ll tell you the same thing he tells every homeowner during our first walkthrough: “Do it right the first time or you’ll do it twice - and the second time always costs more.”
Why South Florida’s Wind Zone Inflates the Numbers You See Online
National cost guides are misleading for South Florida homeowners because they blend data from across Florida. The distinction matters.
South Florida sits in the High Velocity Hurricane Zone (HVHZ), where the Florida Building Code requires windows rated to 180+ mph design pressure. Standard impact vs non impact windows in South Florida, FL approved for lower wind zones like Palm Beach or St. Lucie cost 15-25% less. When you see a “$650 per window” figure on a national site, it’s probably not HVHZ-rated product.
This is why we specify HVHZ-rated brands on every South Florida job. The product has to survive the test chamber, yes, but it also has to pass Miami-Dade County’s product control approval - a separate, stricter protocol than standard Florida Product Approval.
Brand-Tier Pricing: What Three Real Options Look Like
Groundwork works with eight window and door brands including Windows & Doors in South Florida specialists like PGT, CGI, and Simonton. Here’s how three common selections break down for a typical 3/2 South Florida home with 10-12 openings:
| Brand / Series | Unit Cost per Opening | Installed with Bucks, Permit, Stucco | Best For |
|---|---|---|---|
| PGT WinGuard Aluminum (HVHZ) | $650-$950 | $900-$1,300 | Maximum impact rating, coastal exposure |
| CGI Guardian (HVHZ) | $600-$850 | $850-$1,200 | Strong rating with slimmer frame profiles |
| Simonton StormBreaker Plus | $500-$750 | $750-$1,050 | Budget-conscious full-home replacement |
These are real ranges from our current supplier pricing, not theoretical figures. The spread within each line reflects size variations, custom grid patterns, and whether we’re dealing with fixed picture windows versus operable casements or horizontal rollers.
Our full Windows & Doors service page covers the complete brand roster including Andersen, Pella, Marvin, Milgard, and Jeld-Wen for homeowners considering non-impact or architectural-grade options in protected areas.
The Insurance Math Most Contractors Don’t Walk You Through
Here’s where the project cost flips into investment territory. Florida homeowners with documented impact openings on all windows, impact sliding glass doors, and garage doors typically see 25-45% reductions in their wind premium.
On a $4,000-$6,000 annual wind premium common in coastal South Florida, that’s $1,000-$2,700 back in your pocket every year. Full payback on a complete window replacement project often lands in the 4-7 year range.
But - and this is critical - partial replacement kills the benefit. We’ve seen homeowners in Pembroke Pines replace their front windows with impact-rated PGT units, leave the original jalousies on the sides and rear, and expect the full mitigation credit. The inspector checks every opening. Non-impact windows anywhere on the envelope mean no wind mitigation form, no premium reduction. The ROI math only closes when you complete all openings.
This is why our estimates always include the full opening count, even when a homeowner initially asks about “just the front of the house.” We’re not upselling; we’re showing you the actual cost to get the benefit you’re budgeting for.

Replacement with HVHZ-rated hurricane windows qualifies for 25-45% wind premium reductions and eliminates repeated maintenance on corroding frames. For most South Florida homes built before 1994, full replacement is the cost-effective path when you factor in the 4-7 year insurance payback.
No - proper installation requires permitting, fabrication of aluminum bucks for CBS construction, and scheduled inspection.

We coordinate permits with Miami-Dade or Broward and your specific municipality to keep the timeline tight.
