Charlotte County's Permit Process, Handled for You

Impact window and door replacement in unincorporated Charlotte County requires a permit through the Building Construction Services division of the Community Development Department (18400 Murdock Circle, Port Charlotte), under Florida Building Code Section 105.1. We submit the permit application, provide the Florida Product Approval (FL#) or Miami-Dade Notice of Acceptance (NOA#) documentation for the specific windows and doors going into your home, and schedule the required building, structural, and where applicable zoning and right-of-way inspections — you don’t have to touch the Accela portal or call the county office yourself.

Engineered for Canal-Front and Coastal Exposure

Port Charlotte's canal system — the waterways around El Jobean, Gardens of Gulf Cove, and the Edgewater/Midway corridor — puts a meaningful number of homes directly on open water with no windbreak. That changes the design pressure and water-infiltration rating a window needs to meet, even though the county-wide wind code is the same whether you're on a canal lot or inland near Deep Creek or Harbour Heights. We calculate design pressure per opening before ordering, not after, so the glass and framing specified on your permit application match what actually gets installed.

Beyond storm protection, impact glass cuts down on road noise from Kings Highway and US-41, blocks UV that fades flooring and furniture, and typically qualifies for a wind mitigation credit on your homeowners insurance once installed — we provide the documentation your carrier will ask for.

Impact Windows: Eastern and PGT

We install Eastern Windows, manufactured locally in Fort Myers, and PGT impact windows, both Florida-based manufacturers with local support rather than an out-of-state import with a multi-month lead time. Every window we install carries Miami-Dade NOA approval, the strictest impact and wind-load rating issued in the United States, which automatically clears Charlotte County's requirement. Where a project's budget calls for it, we'll also lay out a non-impact window paired with a code-compliant shutter system as a lower-cost, permit-approved alternative — and tell you plainly whether that fits your home.

Impact Entry Doors: Thermatru

Thermatru impact-rated entry doors replace older, non-rated front doors that are often the first point of failure in a storm. Wood bucking repair and finish carpentry around the opening are part of the installation, not billed separately, and if you're converting a window opening into a door — or the reverse — our crews handle that structural change as part of the same permit.

Who's Doing the Work

Two installation crews work exclusively for 360 iMPACT — there’s no rotating pool of day-labor subcontractors bidding your job out to whoever’s available that week. Owner Jeremiah Wiederhold, a Florida State Certified Building Contractor (License #CBC1267699), oversees quality across every project personally, and the company carries an A rating with the Better Business Bureau.

What It Costs and How to Pay for It

Pricing depends on the number of openings, glass package, and whether structural bucking repair is needed — we quote that specifically during your free in-home estimate rather than giving a blended average that doesn’t reflect your actual home. For homeowners who qualify, 0% interest financing is available; ask your project consultant about current terms when you schedule your estimate.

FAQ

Does Charlotte County require a permit for impact window and door replacement?
Yes. Under Florida Building Code Section 105.1, replacing or installing impact-resistant windows and doors requires a permit through the Charlotte County Building Construction Services division. We pull the permit, submit the product approval numbers for the exact windows and doors going in, and schedule the required inspections — you don’t deal with Accela or the county office directly.
An FL# is a Florida Product Approval number issued statewide; an NOA# is a Miami-Dade Notice of Acceptance, the strictest impact rating in the country. We install products carrying Miami-Dade NOA approval, which automatically satisfies Charlotte County’s requirements — you’re covered by the higher standard either way.
It changes the wind load and water infiltration numbers we design to, not the permitting process itself. Waterfront and canal-front lots with no windbreak get engineered to a higher design pressure than an inland lot on the same street grid, and we run those calculations before ordering your windows, not after.
We’re based in Fort Myers and have run projects throughout Charlotte County, including Port Charlotte, Deep Creek, and Harbour Heights, since opening. Owner Jeremiah Wiederhold holds Florida contractor license CBC1267699 and personally oversees project quality across our service area.
Two crews work exclusively for 360 iMPACT — not a rotating pool of day-labor subcontractors. The same team that measures your openings typically installs them.
We correct it at no cost to you and reschedule the inspection. Because we handle the permit and product approval submission ourselves, mismatches between what’s specified and what’s installed are rare — but if it happens, it’s on us to fix, not you.
