Fast, Reliable Window Replacement Across Iona
Window replacement in Iona, FL runs $800 to $1,500 per opening for impact-rated units installed, with full-frame replacement on older CBS ranch homes typically landing between $1,200 and $1,800 per window once you factor in the county’s stricter coastal documentation requirements. We know this market cold because our crews work the McGregor Boulevard corridor every week. Ed Winslow founded this company in 2011, and his name is on the door and on every job we do. Call (239) 453-7751 for a free in-home measure and a written, line-item quote.
Iona sits in a unique spot. The Caloosahatchee River estuary wraps the north side, Gulf tidal influence pushes in from the west, and Hurricane Ian’s 2022 track passed directly through this corridor. That combination means window replacement here isn’t a generic job. It’s a coastal, wind-rated, salt-exposed, permit-intensive project with county inspectors who expect documentation most installers never bother to prepare.
Why Winslow Windows & Doors Is Iona’s Preferred Window Replacement Company
We answer the phone. Day or night, you get a live person at (239) 453-7751, not a voicemail loop. For Iona homeowners who’ve been through hurricane season or a bad contractor experience, that matters more than any slogan we could print.
Our technicians are background-checked, uniformed, and arrive in marked vehicles so you know exactly who is at your door before the first handshake. We’re a local outfit with a published address and license number. Ed Winslow owns the company. No shell entities, no anonymous call centers, no ticket numbers.
Iona customers call us because we understand what Lee County’s building department now demands for coastal CDP zones. A permit that gets rejected for missing Miami-Dade NOA documentation costs you weeks and money. We prepare that paperwork before the first inspection, not after a red tag.
Our Window Replacement Services in Iona
Full Frame Replacement
Most Iona homes built in the 1970s through 1990s still carry original single-pane aluminum jalousie or slider windows installed before Florida’s post-Hurricane Andrew code overhaul. Full frame replacement removes the entire window down to the rough opening, letting us address rotted sills, failed flashing, and water intrusion that insert replacements can’t reach. On acreage properties where open-lot drainage shifted after Ian, this is the difference between a window that seals and one that leaks at the first heavy afternoon storm. Expect $1,200 to $1,800 per opening for impact-rated full-frame units in Iona.

Insert Window Replacement
If your existing frames are square, sound, and still shedding water, insert replacement windows fit inside the original frame and cut labor time. This is the more budget-friendly route, but Iona’s double-salt exposure means we inspect the old frame carefully before recommending an insert. Aluminum frames from the mid-2000s are already showing spalling hardware and failed weatherstripping in this coastal stretch. When the frame is compromised, an insert just hides the problem. Inserts in Iona typically run $800 to $1,200 per opening.

Vinyl Replacement Windows
Vinyl resists the salt oxidation that eats aluminum frames along the Caloosahatchee estuary and Gulf-facing blocks. We install PGT and Mr-Glass vinyl impact units with insulated laminated glass. Vinyl won’t corrode in Iona’s brackish air, and modern multi-chamber frames hold design pressures that older aluminum can’t touch. A standard vinyl impact replacement window runs $900 to $1,500 installed depending on size and wind zone.

Energy-Efficient Upgrade
Swapping single-pane jalousies for impact-rated Low-E insulated glass changes the thermal profile of an entire Iona home. On a McDonough Drive ranch or a Riverside Drive bungalow, that means lower cooling loads in an environment where the HVAC runs ten months of the year. We scope energy upgrades by room, orientation, and existing frame condition so you’re not paying for glass rated beyond what your opening needs.

Trusted Brands We Service in Iona
We are authorized installers for PGT, Mr-Glass, and Therma-Tru, among eight premium brands. When you call us for Window Replacement service in Iona, we spec the right product for your wind zone and exposure rather than defaulting to whatever is on the shelf. That means PGT WinGuard for coastal openings with high design pressure requirements, Mr-Glass for budget-conscious vinyl retrofits, and Therma-Tru when the project extends to entry doors. We coordinate delivery through Fort Myers suppliers and inspect every unit for transport damage before it goes on our truck.
Common Window Replacement Problems We See in Iona Homes
- Salt-driven frame failure: The Caloosahatchee River to the north and Gulf air from the west create a double-salt environment that oxidizes aluminum frames faster than anywhere inland in Lee County. Our crew recently replaced full-frame impact windows on a 1980s CBS ranch off McGregor Boulevard where the original sliders had oxidized frames and spalling hardware from exactly this exposure. We installed PGT WinGuard vinyl impact units, and the inspector pulled the Miami-Dade NOA stickers before signing off on final.
- Post-Ian permit rejections: Lee County building officials now require Miami-Dade NOA documentation on the window unit itself, not just Florida Product Approval, for replacement permits in Iona’s coastal CDP zones. Homeowners who submit specs with only Florida Statewide Approval get kicked back and lose weeks.
- Drainage and slab-edge standing water: Hurricane Ian changed open-lot grading across Iona. Homes that never had standing water before now hold it against slab edges after a heavy rain. Replacement frames rot and weatherstripping seals fail faster when sill flashing and slope correction are skipped.
- Acreage setbacks restricting openings: On larger Iona lots with septic and well systems, county setbacks limit where a window can be enlarged for egress or view. A new rough opening that encroaches on required clearance fails inspection, and you won’t know until the red tag arrives unless someone scopes it upfront.

What Window Replacement Costs in Iona
The real anchors for Iona are $800 to $1,500 per window for impact-rated units installed, with full-frame replacements on pre-1994 construction running higher because of the extra flashing, sill repair, and stucco patch work. What moves the price here: opening count, wind zone (Iona’s Gulf-adjacent blocks carry higher design pressure requirements than inland Lee County), floor height on two-story sections, and frame material. A Mr-Glass vinyl insert costs less than a PGT WinGuard full-frame unit with Miami-Dade NOA documentation. We provide a free in-home measure and a written line-item quote before any work starts, and the price on that quote is the price you pay. No change orders, no surprises on the invoice. Call (239) 453-7751 to schedule your measure.
Florida Pays You Back
Iona homeowners can stack real incentives on window replacement. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, which includes impact-rated windows in many cases. Florida’s sales-tax exemption applies to impact-resistant windows and doors. The federal 25C energy credit returns 30% of product cost up to $600 per year on qualifying energy-efficient units. After a wind-mitigation inspection (typically $75 to $150), many Iona homeowners also see windstorm-premium credits averaging around 25% on the windstorm portion of their policy. We can’t guarantee what your carrier or the program will finalize, but we’ll give you the documentation to apply. Impact windows versus hurricane shutters: shutters only protect when someone is home to hang them, and they don’t stop salt-air corrosion on the windows themselves. A permanent impact-rated installation protects every hour of every day, with no panels to store or hinges to seize before a September storm. We never install shutters, but we’re glad to explain the comparison honestly.
Building on Acreage Around Iona
Iona isn’t all tight ranch lots off McGregor. A significant share of our work happens on larger parcels where county permitting, septic and well setbacks, and open-lot drainage change the whole job scope. When a homeowner on an acreage lot wants to enlarge a window for light, egress, or a view toward the Caloosahatchee, the first thing we check is setback clearance. Septic drain fields and well heads carry mandatory separation distances in Lee County, and a new rough opening that encroaches on those zones fails permit review before we ever cut stucco. We scope that before quoting, so the price you get reflects reality, not optimism.
Open-lot grading after Ian left some Iona acreage homes with drainage paths that now send sheet flow against the slab. That means replacement window frames lose seals faster, especially on the windward side. When we quote full-frame replacement on these properties, we include sill flashing details and, where needed, a slope correction conversation. You don’t want new windows sitting in a puddle line every summer afternoon. Long material hauls through the McGregor corridor from Fort Myers suppliers also mean transport damage shows up in jamb extensions if units aren’t inspected at pickup. We inspect at the supplier before loading, not after the truck arrives at your driveway. None of this appears on a big-box estimate. It all appears on ours.

FAQs - Window Replacement in Iona
Lee County building officials in Iona’s coastal CDP zones now require Miami-Dade NOA documentation on the window unit itself for post-Ian replacement permits, a stricter enforcement posture than neighboring inland jurisdictions. Not every brand carries Miami-Dade NOA for every configuration, so the window you saw online might not pass here. We spec units with the correct NOA paperwork matched to your opening and wind zone, so the permit clears on the first pass. Call (239) 453-7751 and we’ll verify your specs before you buy anything.
Usually yes, but only if the new rough opening clears your septic drain field and well head setbacks. Lee County enforces minimum separation distances for any structural change near those systems, and an enlarged window opening that encroaches fails permit review. We survey the site setbacks before quoting any enlargement so the job is scoped correctly from day one. Call (239) 453-7751 for a free site walk.
Iona sits between two salt-air sources, the Caloosahatchee River estuary and Gulf tidal influence, which oxidizes aluminum frames and spalls hardware faster than inland Lee County locations. That’s why we recommend vinyl or protected composite frames for most Iona replacements; they simply don’t corrode the way aluminum does in this air. Even mid-2000s aluminum frames here are already showing failure. Call (239) 453-7751 and we’ll tell you honestly whether your existing frames are worth saving.
Yes, the 20 to 30 percent cooling reduction figure is typical when you swap single-pane jalousies or sliders for impact-rated Low-E insulated glass, especially in Iona where the air conditioner runs most of the year. The bigger variable is how many windows you replace and their orientation. A west-facing wall of old single-pane glass is losing cooling dollars every afternoon. We scope the upgrade by room and orientation so you’re not overpaying for glass ratings you don’t need. Call (239) 453-7751 for a free energy-focused walkthrough.
The most common reason we see is missing Miami-Dade NOA documentation on the window unit itself, which Lee County now requires in Iona’s coastal CDP zones. Standing water against the slab edge from post-Ian drainage changes also fails sill flashing checks when the flashing detail doesn’t include proper slope correction. If you’ve been red-tagged and the installer isn’t fixing it, call (239) 453-7751. We’ll come take a look and tell you exactly what the inspector is looking for.
