Impact windows and doors in Charlotte County

Charlotte County sits outside the HVHZ in the FBC 8th Edition Wind-Borne Debris Region with 150–160 mph ASCE 7-22 Risk Category II design wind speeds, where Hurricanes Charley (2004) and Ian (2022) tested every home. We handle permitting through Murdock Circle and Punta Gorda City Hall, averaging from about $900 per window.

Charlotte County homes

We know Charlotte County homes

Charlotte County wraps around the confluence of the Peace and Myakka rivers into Charlotte Harbor and stretches west across the Cape Haze peninsula to Lemon Bay and Manasota Key. Incorporated Punta Gorda permits through the City of Punta Gorda Building Division at 326 W Marion Avenue (including Historic Overlay review where applicable), while unincorporated Port Charlotte permits through Charlotte County Building Construction Services at 18400 Murdock Circle via Accela Citizen Access. We also serve Englewood, Rotonda, Charlotte Harbor, Charlotte Park, Cleveland, Grove City, Harbour Heights, Manasota Key, and Solana across Charlotte County.

We serve Charlotte County homes from our Fort Lauderdale office. Roofing is Miami-Dade, Broward and Palm Beach only. Call 754-800-4115 for a free on-site measurement and receive an itemized written quote within 24–48 hours.

Impact window and door cost across Charlotte County

Across the county, installed impact windows average $800–$1,800 per opening ($1,100 for a standard 37 by 63 inch single-hung or $900 for a 37 by 50 inch fixed architectural lite).

Exposure D waterfront homes along the seawall canals of Punta Gorda Isles, Burnt Store Isles, and South Gulf Cove, deed-restricted golf villas in Rotonda West, and coastal homes on Manasota Key requiring <= 0.45 VLT sea-turtle glazing sit toward the upper half of the range.

Hurricanes Charley (2004), Ian (2022), Helene & Milton (2024)

Few Florida counties have been tested like this coastline: Category 4 Hurricane Charley (August 13, 2004) and Category 4 Hurricane Ian (September 28, 2022) both drove their eyewalls directly up Charlotte Harbor into Punta Gorda and Port Charlotte, followed in 2024 by Hurricane Helene's storm surge on Manasota Key and Lemon Bay and Hurricane Milton's destructive outer eyewall winds.

Replacing aging 1970s–1990s single-pane jalousies and aluminum sliders with laminated Low-E impact glass provides 24/7 protection for 150–160 mph ASCE 7-22 design wind speeds while meeting FBC Climate Zone 2 thermal limits (SHGC <= 0.25, U-factor <= 0.40).

Windows and doors for every Charlotte County home

From deepwater sailboat canal estates in Punta Gorda Isles and Port Charlotte's Grassy Point to deed-restricted homes in Rotonda West and riverfront lots in Cleveland and Harbour Heights, we match every opening to its exact ASCE 7-22 design pressure and 316 stainless coastal hardware spec.

For exterior doorways, we install out-swing French doors, multi-panel pocketing lanai sliders, fiberglass entry doors, and wind-rated garage doors. Our hinged impact doors (French and entry doors) swing out. Sliding glass doors and garage doors don't swing.

Grants and insurance

My Safe Florida Home and your wind-mitigation form

If you qualify for My Safe Florida Home, the state pays $2 for every $1 you pay, up to $10,000, after the program's free wind-mitigation visit (Fla. Stat. §215.5586). How the program works.

Impact windows and doors count as opening protection, Question 7 on the state's wind-mitigation form, OIR-B1-1802. A licensed inspector fills it out after the work, and your insurer sets the discount.

Questions

Charlotte County impact window questions

Is Charlotte County in the High-Velocity Hurricane Zone (HVHZ)?

No—the HVHZ covers only Miami-Dade and Broward counties. Charlotte County is governed by the standard FBC 8th Edition Wind-Borne Debris Region (§ 1609.1.2), where a state Florida Product Approval (FL#) rated for your lot's design pressure is sufficient and a Miami-Dade NOA is accepted as an optional equivalent.

What design wind speeds apply across Charlotte County?

Under official county ASCE 7-22 Risk Category II maps, design wind speeds range from 150 mph inland along the upper Peace River corridor to 160 mph across Punta Gorda, Port Charlotte, Rotonda West, Englewood, and Manasota Key.

Which building department permits my home?

Homes inside the City of Punta Gorda permit through the City of Punta Gorda Building Division at 326 W Marion Avenue; unincorporated communities including Port Charlotte, Rotonda West, Englewood, and Manasota Key permit through Charlotte County Building Construction Services at 18400 Murdock Circle via Accela.

Does Republic offer roofing in Charlotte County?

No—in Charlotte County we install impact windows and exterior doors only. Roofing is Miami-Dade, Broward and Palm Beach only.

Where is sea-turtle tinted glass required?

Gulf- and Lemon Bay-visible windows on Manasota Key and beachfront parcels require <= 0.45 (45%) visible light transmittance (VLT) glass under Charlotte County Code Ch. 3-5, Art. XII during the May 1–October 31 nesting season.

How does the FEMA 50% rule affect canal and coastal homes?

Many waterfront lots in Punta Gorda Isles, Burnt Store Isles, South Gulf Cove, and Manasota Key sit in FEMA Flood Zones AE or VE. Under the FEMA 50% substantial improvement rule, if cumulative permitted improvements reach 50% of the building's market value, the structure must meet current flood elevation standards—though a window and door replacement alone rarely approaches that threshold.

Can Rotonda West, Punta Gorda Isles, or Deep Creek HOAs reject impact windows?

No—under Fla. Stat. § 720.3035(6) for HOAs and § 718.113(5) for condominiums, associations can review frame color and muntin style but cannot prohibit code-compliant impact windows.

When is a Notice of Commencement required?

State law requires a notice of commencement over $5,000. We record it with the Charlotte County Clerk of the Circuit Court at 350 E Marion Avenue in Punta Gorda before the first inspection approval.

What do impact doors cost?

Installed single French doors average $2,800–$4,000, double French doors average $3,800–$7,000, and 2-panel sliding glass doors average $2,500–$3,500 (plus $600–$800 per additional panel).

How do homeowners earn OIR-B1-1802 insurance discounts?

Once every exterior window, door, skylight, and garage door is impact-protected and passes final inspection approval, a wind-mitigation inspector signs Form OIR-B1-1802 for mandatory windstorm discounts under Fla. Stat. § 627.0629.

What labor warranty covers the installation?

The lifetime labor warranty covers you, the original owner. It doesn't pass to a new owner if you sell.

  • Up to 30 feet: the large-missile test of ASTM E1996.
  • Above 30 feet: the small-missile test of the same standard.
  • Each unit needs a Florida Product Approval, or a Miami-Dade NOA, covering its size and design pressure.

Charley (2004) & Ian (2022)How two Category 4 harbor landfalls tested Charlotte County

2004, 2022 & 2024

August 2004 Charley & September 2022 Ian Eyewalls

  • Category 4 Charley (Aug 13, 2004) and Category 4 Ian (Sept 28, 2022) both tracked straight up Charlotte Harbor into Punta Gorda and Port Charlotte.
  • In Fall 2024, Helene pushed Gulf surge across Manasota Key and Grove City before Milton swept the harbor.
  • Every local parcel maps inside the 150–160 mph Wind-Borne Debris Region with 0.25 SHGC solar control.
  • Swapping 1970s jalousies and single-pane sliders for laminated glass locks out harbor debris without hanging metal panels.
