The average South Florida homeowner replacing standard windows with impact-resistant units will invest somewhere between $800 and $1,500 per window—installed. But that single number tells almost nothing useful about what you’ll actually pay. Window size, glass type, frame material, home configuration, and permit requirements all shift that figure dramatically in either direction.
If you’re weighing hurricane protection upgrades for a home in Palm Beach, Broward, or Southwest Florida, understanding what drives the cost—and what separates a legitimate installation from a risky shortcut—is the most valuable research you can do before picking up the phone.
What Determines Impact Window Installation Cost
No two homes have identical needs, and cost estimates that ignore your specific property aren’t worth much. Here are the primary factors that influence what a professional impact window installation will cost you in 2026.
Window Size and Quantity
This is the most straightforward variable. Larger windows require more laminated glass, heavier frames, and more labor to handle safely. A standard double-hung window in a bedroom might measure 36″ x 48,” while a panoramic great room window could run 6 feet wide or wider. Larger openings cost proportionally more in materials and installation time.
Quantity also matters for pricing. Replacing every window in a home at once typically yields better overall pricing per unit than replacing just two or three, because mobilization costs—permits, inspections, crew travel, equipment—are spread across more openings.
Glass and Frame Specifications
Not all impact glass is the same. Florida Building Code requires that impact-resistant windows pass rigorous large missile impact testing and pressure cycling standards as defined by the Florida Building Commission. Within compliant products, homeowners still choose between:
- Single-pane laminated glass — meets code at lower cost but offers less energy efficiency
- Insulated laminated glass (IGU) — two panes with an air or argon-filled space, significantly better thermal performance
- Low-E coatings — reduce solar heat gain, helping manage cooling costs in South Florida’s climate
- Tint options — reduce glare and UV exposure without compromising storm protection
Frame materials also vary. Aluminum frames remain the most common choice in South Florida because of their strength-to-weight ratio and corrosion resistance in coastal salt air. Vinyl frames offer excellent thermal performance at competitive cost. High-end fiberglass frames represent a growing option for premium installations.
Manufacturers like PGT, CGI, and ES Windows—brands we’re authorized to install—offer a range of specifications across each frame material, which allows us to match products to your home’s performance goals and budget.
Window Style and Configuration
The operating style of a window affects both material cost and installation complexity:
- Single and double-hung — most common, moderate cost
- Casement and awning — hinged styles can seal tighter but hardware adds cost
- Fixed (picture) windows — no moving parts, generally lower cost per square foot
- Sliding glass windows — require larger frames and heavier hardware
- Custom shapes — arched, trapezoid, or circular windows require custom-fabricated frames and carry a significant premium
Installation Complexity
Beyond the windows themselves, the condition of your existing openings matters. In older homes across Palm Beach and Broward counties, wood frame rot, corroded rough openings, or non-standard opening dimensions can require additional carpentry before new frames can be properly set and sealed. This adds labor time and materials that aren’t visible in a window-only quote.
Second-story and third-story windows require additional safety equipment and more time. Impact windows are substantially heavier than standard residential windows—a large insulated unit can weigh well over 100 pounds—which affects how crews work at height.
Permits, Inspections, and Code Compliance Costs
Every legitimate impact window installation in Florida requires permits and inspections. This is not optional, and any contractor who suggests otherwise is putting your family and your investment at serious risk.
Permit fees vary by county and municipality. Palm Beach County, Broward County, and Southwest Florida counties each have their own fee schedules. For a whole-home replacement, permit costs typically range from a few hundred to over a thousand dollars depending on project scope and jurisdiction.
More importantly, unpermitted work creates real problems: it won’t pass a home inspection when you sell, it can void manufacturer warranties, and it leaves you without the code compliance documentation that supports insurance adjustments following a storm. According to FEMA’s wind retrofit guidance for single-family homes, building code-compliant installation is a foundational element of effective hurricane protection—the product alone isn’t enough.
As a Florida Certified General Contractor, we pull permits, manage inspections, and ensure every installation meets current Florida Building Code requirements. That compliance documentation is part of what you’re paying for—and it’s worth every dollar.
Don’t Overlook the Doors and Garage
Many homeowners focus exclusively on windows when planning hurricane protection, but impact doors and garage doors are equally critical components of a complete protection system. A home is only as strong as its weakest opening.
Our impact door installation services cover entry doors, sliding glass doors, and French doors—all engineered to meet the same Florida Building Code standards as your windows. Entry doors from manufacturers like Therma-Tru and impact-rated sliding units offer the security and storm protection your family needs at every entry point.
Garage doors deserve particular attention. The garage door is often the largest single opening in a home, and failure during a hurricane can allow catastrophic pressure changes that compromise the entire structure. Our impact garage door installation options include wind-rated units from brands like Amarr and Clopay, as well as our specialty custom impact glass garage doors—an increasingly popular upgrade for South Florida homeowners who want natural light, curb appeal, and storm protection in one product.
Budgeting for comprehensive protection—windows, doors, and the garage—is the approach we recommend to every family we consult with.
What Separates a Fair Price from a Cheap Quote
In South Florida’s competitive contractor market, significant price variation exists—and the lowest quote is almost never the best value. Here’s what a fair installation price actually includes:
- Florida Building Code-compliant products with current approval numbers
- Licensed contractor supervision (Florida Certified General Contractor)
- Permit application and inspection management
- Proper flashing, sealing, and weatherproofing at every opening
- Responsible removal and disposal of old windows
- Manufacturer warranty registration
- Post-installation cleanup and walkthrough
A quote that skips permits, uses non-licensed labor, or installs products without current Florida Product Approvals might look attractive on paper. But when a storm arrives—or when you try to sell your home—the hidden costs of that shortcut become very real.
The Insurance Information Institute consistently notes that documented, code-compliant improvements are the foundation for any insurance-related benefit from storm protection upgrades. That documentation comes only from properly permitted, inspected work.
Frequently Asked Questions
How much does impact window installation cost per window in South Florida?
Most South Florida homeowners pay between $800 and $1,500 per window for professionally installed impact units, with custom shapes, large picture windows, and premium glass specifications ranging higher. Whole-home projects may offer better per-unit pricing due to shared mobilization and permit costs.
Does impact window installation in Palm Beach County require a permit?
Yes. Every impact window installation in Palm Beach County, Broward County, and throughout our Southwest Florida service area requires a building permit and inspection. This applies regardless of the number of windows being replaced. Unpermitted installations risk insurance complications, resale issues, and may leave you without valid warranty coverage.
How long does a full impact window installation take?
A whole-home replacement on a typical single-story South Florida residence generally takes two to five days of installation time, depending on the number of openings, window styles, and site conditions. Permit processing time—which varies by county and municipality—occurs before installation begins and should be factored into your project timeline.
Do impact windows qualify for Florida insurance savings?
Impact-resistant openings that meet Florida Building Code requirements may qualify for wind mitigation credits that can reduce homeowner’s insurance premiums. The actual savings vary by insurer, policy structure, and the specific features of your installation. A wind mitigation inspection, performed after permit-compliant installation is complete, documents your improvements for your insurance provider.
Is it worth replacing windows and doors at the same time?
In most cases, yes. Completing your entire envelope—windows, entry doors, sliding doors, and garage doors—in one project maximizes code compliance documentation, minimizes the number of permit cycles, and ensures your home’s protection is comprehensive rather than partial. Many homeowners also find coordinating a single project more convenient than staging multiple renovations.
