AfterFast, Reliable Custom & Geometric Windows Across Iona
Custom and geometric windows in Iona run $2,500 to $5,000 per large or arched opening installed, with standard impact-ready shaped units starting around $1,100. We measure, order, and install shaped impact windows that satisfy the Miami-Dade NOA documentation Lee County inspectors now require on most permitted Iona jobs. Winslow Windows & Doors handles every part of that process, from the first measurement off McGregor Boulevard to the final inspection sign-off. Call (239) 453-7751 for a free in-home measure and a written line-item quote before you commit to anything.
Iona homes are not like the tract subdivisions going up east of I-75. Most of the housing stock here went in between the 1970s and early 1990s: single-story CBS ranches with original aluminum single-pane sliders, jalousie windows, and the occasional fixed picture window that has never sealed correctly. When a homeowner in the Iona area wants an arched window over the lanai or a radius-top geometric unit on the front elevation, the conversation starts with the wall itself, not with a catalog page. That is exactly how we approach every Custom & Geometric Windows job: open it right, frame it right, flash it right, and set a unit that carries the right approval for this exact wind zone.
Ed Winslow’s name is on the door, and it is on every window we set in Iona. That means something specific. It means you get a live person on the phone at (239) 453-7751, a background-checked tech in uniform at your door, and a 36500-Day Done Right Promise on the finished opening. One hundred years of being held to it. No national chain will say that because no national chain will still exist to honor it.
Why Winslow Windows & Doors Is Iona’s Preferred Custom & Geometric Windows Company
We have been installing impact-rated shaped and geometric windows across Lee County since 2011, and Iona has become one of the most demanding corridors we work. That is not a complaint. It is a fact that shapes how we buy, specify, and install. The post-Ian building department posture in this exact stretch between the Caloosahatchee River and the Gulf requires documentation that other nearby communities do not ask for. We already carry it on every unit we order for Iona.
Iona homeowners call us after another company quoted a window that would not pass final inspection. That is the most common first conversation we have here. The unit looked right, the price looked fine, but the Florida Product Approval number on the sticker did not match the Miami-Dade NOA the coastal CDP inspector pulled up during the permit review. By the time the homeowner found out, they had already paid a deposit. We get called to replace the replacement. Our job is to make sure that never happens on a Winslow job.
Every tech who shows up in Iona is background-checked and arrives in uniform, with the truck marked and the paperwork in hand. Homeowners know exactly who is at the door before they open it. And when they call the office at 2 a.m., a live person answers. Not a voicemail loop. Not a call center in another state. A person who knows what a design pressure rating means and why it matters in Iona.
Our Custom & Geometric Windows Services in Iona
Most windows are rectangles. Iona has never been a rectangle kind of place. The 1970s builders along McGregor and the streets branching toward the river put arched transoms above the front door, octagonal porthole windows in the gable ends, and trapezoid glass over the lanai sliders. When those units fail, you cannot call a production-window installer and order a stock replacement. You need someone who measures the opening as it actually exists, builds the unit to the frame, and handles the framing corrections that forty years of salt air and settling have made necessary.
Custom Impact Windows
Custom impact windows in Iona typically run $1,100 to $2,200 per opening for midsized shaped units, more for curves and oversized glazing. These are laminated-glass units built to a specific design pressure, not a stock size pulled off a warehouse rack. Every unit we order for Iona carries both a Florida Product Approval number and, where the permit requires it, the matching Miami-Dade NOA documentation. That dual approval is what passes inspection in the coastal CDP zones after Hurricane Ian.
Geometric & Shaped Windows
Geometric windows are trapezoids, pentagons, triangles, octagons, and anything else the original architect dreamed up that does not fit a standard frame. In Iona’s 1970s-through-1990s CBS stock, those units are almost always original aluminum with failed seals and spalled frames. We order the replacement as a true geometric impact unit, built from the actual diagonal measurements of the opening, and we reframe or correct the rough opening as needed. We do not shim a square unit into an angled hole and call it close enough. That is not how custom windows pass inspection in Iona.
Arched & Curved Windows
Arched and radius-top windows over Iona lanais and front entries are among the most common requests we field, and also the most inspection-critical. The curve must be true, the jamb must be solid, and the unit must carry large-missile impact certification if the rough opening exceeds the square-foot threshold. Iona sits in a wind zone where those thresholds matter. We specify the curve from the existing opening, verify the framing behind it, and set the unit to the design pressure the Miami-Dade NOA calls for, not a guess.
Oversized Openings
Oversized geometric and curved openings in Iona hide decades of trouble: undersized headers, failed flashing, rotted jamb material, and salt-air corrosion eating the fasteners. When we take an oversized opening down to the studs, we inspect what is behind it before we set the new unit. Our techs have found original openings on McGregor Boulevard ranches that were never flashed correctly from the day they were built. We fix that, then install the window. Call (239) 453-7751 if you are looking at a big opening that worries you. It probably should.

Trusted Brands We Service in Iona
Winslow Windows & Doors is an authorized installer for PGT, CGI, CWS, and ViewLux, among the full lineup we carry. For Iona specifically, we lean on CGI and PGT custom lines because their engineering documentation is consistently accepted by Lee County’s stricter coastal CDP review. That saves Iona homeowners the back-and-forth with a plan reviewer who expects Miami-Dade NOA paperwork on the unit itself. We do not sell shutters, and we do not install them. We compare against them honestly, because several Iona homes have both, and you should know the difference before you spend. A permanent laminated impact window protects your home with no panels to haul out of the garage when a storm track forms in the Gulf.
Common Custom & Geometric Windows Problems We See in Iona Homes
- Original aluminum jamb spalling from double-salt exposure. Iona is caught between the Caloosahatchee estuary to the north and Gulf tidal air to the west. That salt load corrodes 1970s and 1980s aluminum frames faster than inland Lee County, and by the time a homeowner notices the sash racking, the jamb is often too far gone to save.
- Rough openings that do not match the new unit’s design pressure. Older Iona CBS homes have rough openings sized for single-pane glass, not laminated impact units. The framing needs reinforcement to carry the weight and the wind load, and that work has to happen before the window goes in.
- Failed waterproofing behind the old frame. We routinely find original flashing and sealant that has been failing for years, letting salt-laden moisture into the wall cavity. Once the old window is out, we correct the flashing and seal before we set the new one.
- Inspection failures on approval paperwork. This is the one that costs Iona homeowners real money and delay. A unit with only a Florida Statewide Approval number is not enough in certain Iona CDP zones. The inspector wants Miami-Dade NOA documentation matching the specific configuration. We order to the stricter requirement every time.
Pricing for Custom & Geometric Windows in Iona, FL
A standard shaped or geometric impact window in Iona starts around $1,100 to $1,500 per opening installed. Arched and radius-top units typically run $1,800 to $2,800 per opening, depending on curve radius and glass package. True oversized openings, the ones that dominate Iona lanai elevations and front gable walls, land between $2,500 and $5,000 each once framing corrections, flashing, and large-missile glass are accounted for. Whole-home custom packages with multiple geometric openings often fall between $12,000 and $25,000 depending on opening count and wind-zone requirements.
What moves the price in Iona is not the brand sticker. It is the opening count, the design pressure the location demands, floor height relative to the wind zone, and what our tech finds when the old frame comes out. We write line-item allowances into every contract at the start, so if a header is undersized or the flashing has failed, you approve the change in writing before we touch it. You never get a surprise on the final invoice. You get a written quote up front, a free second opinion on any competitor’s estimate, and a permanent 10% discount if you are a senior or a veteran. Call (239) 453-7751 to schedule the free measure.
What Custom & Geometric Windows Costs in Iona
Impact windows in Iona generally run $800 to $1,500 per window installed on production openings. A custom single-hung in a non-standard size lands between $900 and $1,800. Large or custom geometric openings run $2,500 to $5,000, and whole-home packages with multiple shaped openings typically span $8,000 to $25,000 or more. The variables are real: opening count, wind-zone design pressure, floor height, and frame material all move the number. We quote every Iona job after a free in-home measure, in writing, with no trip charge anywhere in Lee County. That means the number you approve is the number you pay.
Florida Pays You Back
Florida has money on the table for Iona homeowners replacing old windows with impact-rated units. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades when funding is available. Florida exempts impact-resistant windows and doors from sales tax entirely. The federal 25C energy credit can return 30% of the product cost, up to $600 per year, on qualifying energy-efficient units. Windstorm premium credits after a wind-mitigation inspection commonly average 25% off the windstorm portion of the policy. The inspection itself runs $75 to $150. We cannot guarantee exact grant or premium numbers; those are set by the state, the feds, and your carrier. But we can tell you exactly which of our Iona installations qualify for the documentation they require.
Design pressure ratings on our Iona geometric units are always matched to the opening and the wind zone, and we comply with HVHZ requirements where the location demands it. Ratings are expressed as PSF and never exceed +/-100. Anyone quoting a 150 mph figure as a design pressure is giving you a wind speed and calling it something it is not. Ed Winslow has never done that, and he is not starting now.

FAQs - Custom & Geometric Windows in Iona
Lee County building officials adopted a stricter documentation posture specifically for coastal CDP zones hardest hit by Hurricane Ian in 2022. In Iona, which sits directly in the storm’s path, inspectors now routinely require the Miami-Dade NOA number on the window unit itself, not just the Florida Statewide Approval. Your custom arched window must carry both approvals, with matching configuration numbers, to pass final inspection. We order every Iona unit to that standard from day one. Call (239) 453-7751 before you buy from a company quoting you a unit that only carries statewide approval.
We stop, photograph the condition, and write a change order that spells out exactly what must be corrected and what it costs. You approve it in writing before we proceed. We do not bury it in the final invoice and we do not cut corners to hide it. In older Iona CBS homes, undersized headers and failed flashing are common, especially on openings that have been carrying double-salt moisture for thirty years. The fix is reframing and re-flashing, and the cost is always approved by you first. Call (239) 453-7751 and we will walk you through how the allowance language works before we even schedule the measure.
No. The original aluminum jamb on 1970s and 1980s Iona units is almost always spalled from double-salt exposure, and it cannot support a laminated impact sash in a coastal wind zone. You can get a new aluminum-clad or fully framed unit that mimics a slim sightline, but the jamb itself must be new material sized to the design pressure of the opening. We will show you options from PGT and CGI that keep the look as close to original as code allows. Call (239) 453-7751 for a free measure and we will bring samples.
Yes, in many cases. Iona’s position between the Caloosahatchee River estuary and the Gulf exposes homes to wind loads and salt conditions that inland Lee County subdivisions do not see. The design pressure rating required for your opening is determined by the opening size, height above grade, and wind zone, and it is expressed in PSF, never mph. Coastal CDP zones in Iona often require higher PSF ratings and large-missile impact glazing. We specify each unit to the exact opening, and the rating is stamped on the unit’s Miami-Dade NOA documentation. Call (239) 453-7751 and we will bring the wind-zone map to your measure.
You do not until the old frame is out and the rough opening is inspected. In Iona CBS homes from the 1970s through the 1990s, we regularly find undersized headers, corroded fasteners, and failed waterproofing inside walls that looked fine from the outside. Reuse depends on the condition of the framing and the design pressure required for the new unit. We inspect before we order the sash, and if the opening is not suitable, we quote the reframe as a separate line item you approve before work continues. Call (239) 453-7751 to schedule the inspection.
