What window replacement in Iona actually costs and how long it takes
Window replacement in Iona, FL typically runs $4,500-$15,000 for a full-home job, with most mid-sized single-story concrete-block homes landing between $6,500 and $11,000. The work usually takes two to four days depending on the number of openings and whether we run into water-damaged framing that needs repair before the new units go in. If you’re pricing out specific windows or just need a firm number for your house, call us at (844) 638-7249 and we’ll walk you through a line-by-line estimate.
What makes Iona different from inland jobs is what we pull out of the wall before the new window ever goes in. Salt-driven corrosion on the fasteners, swollen sills from years of horizontal rain off the Caloosahatchee, and original single-pane aluminum frames that lost their thermal seal sometime in the 1990s. We see it week after week on the concrete-block homes that make up most of Iona’s housing stock. The good news: the block structure itself is solid, which means replacement moves faster here than on wood-framed houses farther inland.
How we handle window replacement, start to finish
Every window replacement project in Iona follows a sequence that protects the opening from weather, catches hidden rot before it spreads, and keeps the interior livable while we work. Here’s how it goes day by day.
Stage 1: Measure, spec, and order (1-2 weeks before install day). We measure every opening individually - not just width and height, but the depth of the buck opening, the condition of the concrete surround, and any evidence of past water intrusion at the sill. Those measurements drive the order: frame material, glass package, grid pattern, and whether we need new-construction or retrofit flanges. You’ll sit down with us and choose your window specs during this stage. Once the order is placed, most manufacturers turn product around in two to three weeks.
Stage 2: Interior prep and protection (morning of day 1). Crews lay floor protection from the entry door to every window opening, cover furniture within six feet of each window, and mask off HVAC returns to keep demolition dust out of the ductwork. If you have exterior landscaping or pavers close to the wall, we lay plywood to protect the Iona property’s hardscape from dropped tools or debris.
Stage 3: Remove the old window and assess the opening (roughly 45-90 minutes per window). We cut the old unit out, pull the fasteners, and inspect the rough opening for water damage, termite trails, or corroded steel lintels above the header. In Iona’s 1970s and 1980s concrete-block homes, we frequently find rusted lintels that need wire-brushing, priming, and sometimes replacement before the new window can be set. This is the point where any change-order conversations happen, and we show you exactly what we found before covering it back up.
Stage 4: Set, level, flash, and seal (bulk of days 1 and 2). Each window gets set in the opening, shimmed level and square, and fastened to the block with corrosion-resistant fasteners. We apply a continuous sill-pan flashing at the bottom, then integrate the side and head flashing so water drains outward even in driving coastal rain. On the interior, we insulate the gap between the window frame and the block with low-expansion foam, then trim out the opening. Every window is operated five or six times before we call it done - sashes, locks, tilt-wash mechanisms, everything.
Stage 5: Exterior sealant, cleanup, and walkthrough (final half-day). We tool a high-grade elastomeric sealant around the exterior perimeter of every window. This is the stage where Iona’s salt air demands more than a standard painter’s caulk; we use sealants rated for coastal UV and thermal movement. After final cleanup and a magnet sweep for stray fasteners, we walk the house with you window by window so you can operate and inspect every unit before we leave.
The window choices you’ll actually need to decide on
Most Iona homeowners are replacing original single-pane aluminum windows that came with the house. The jump to modern double-pane insulated glass is the single biggest performance upgrade you’ll make, but there are several decisions within that. Here are the ones that matter for this climate.
- Frame material: vinyl vs. aluminum. Vinyl offers the best thermal performance per dollar and will never corrode in Iona’s salt air. Aluminum is slimmer, often preferred for preserving sightlines on canal-facing walls, but costs more and conducts heat. For most Iona homes we recommend insulated vinyl with welded corners unless the HOA or architectural review requires aluminum.
- Glass package: standard Low‑E vs. impact-rated. Standard Low‑E double-pane glass handles Florida’s heat gain well. Impact-rated laminated glass adds hurricane protection and noise reduction. If your home is within the wind-borne debris zone and you’re replacing more than a few windows, this becomes the dominant cost driver. Impact windows also often lower windstorm insurance premiums in Iona, which offsets some of the upfront cost.
- Grid pattern and style. Colonial grids, prairie grids, or no grids. This is purely aesthetic, but it matters on Iona’s canal-front homes where large fixed picture windows face the water. The grid choice changes the look of the whole elevation from the street or seawall.
- Single-hung vs. double-hung vs. casement vs. slider. Single-hung saves money; double-hung lets you clean both sashes from inside. Casement windows crank outward and seal tighter against wind-driven rain - relevant on west-facing walls that catch afternoon storms. Horizontal sliders are common in Iona’s 1980s homes and straightforward to swap one-for-one.
What window replacement costs in Iona, FL
A full-home window replacement in Iona runs $4,500 on the low end for a smaller house with standard vinyl single-hung windows and no structural surprises, up to $15,000 for a larger home with impact-rated double-hung units, extensive lintel repair, and upgraded trim packages. Most jobs fall between $6,500 and $11,000.
What moves the number:
- Number and size of windows. Ten standard 36‑inch-wide openings cost less than eighteen openings including a large picture window or sliding glass door. Window count is the single biggest lever.
- Impact vs. non‑impact glass. Impact-rated laminated glass adds $300-$600 per window depending on size, but it eliminates the need for shutters and may reduce your windstorm premium. For Iona homes in the wind-borne debris zone, this is often a required upgrade, not an option.
- Condition of the rough opening. If we find rusted steel lintels, rotted wood bucks, or water-damaged framing inside the wall, repair work adds $150-$500 per opening depending on what we uncover. We show you photos and give you a written change order before any extra work starts.
- Frame material and finish. Vinyl is the cost baseline; aluminum runs higher; wood-clad or fiberglass composites sit at the top of the price range and are rarely needed on Iona’s concrete-block homes.
- Permit scope and inspections. Window replacement in unincorporated Lee County requires a building permit, and the fee schedule scales with job valuation. We pull the permit, schedule the inspection, and walk the inspector through every opening.
Every estimate we write is line-itemed with the window count, material specs, labor, flashing and sealant line, permit fee, and debris disposal broken out separately. You’ll know exactly what each dollar covers. Upfront pricing with no surprises means the number on the estimate is the number you pay unless you ask us to add scope. We also offer 0% financing for 18 months and $1,000 off projects over $10,000, which brings larger window-replacement packages into reach for Iona homeowners who want to do the whole house at once rather than phasing it.
What Iona homes specifically do to a window replacement job
Most of the homes we replace windows on in Iona were built between 1972 and 1995, and they share a few things that change how the work goes. They’re almost all concrete-block construction on slab foundations, which means the wall thickness and rough-opening depth are consistent - but the original windows were typically direct-set aluminum frames with no wood buck, so we’re often retrofitting a modern flanged window into an opening that wasn’t designed for one. That demands careful flashing detailing, especially on the sill, because Iona’s afternoon storms push horizontal rain against west-facing walls with enough force to find any gap in the sealant.
The salt air is the other constant. Original steel lintels above window headers rust from the outside in, swelling and cracking the stucco above the window. We wire-brush, treat, and prime those lintels during replacement so the new window isn’t sitting under a deteriorating structural member. On canal-front properties, we also see corrosion on the interior side of window frames in rooms that face the water, even when the windows were kept closed - the humidity and salt content in the air is that aggressive.
Permitting runs through Lee County Building Department because Iona is unincorporated. Post-Ian, the department is still working through a backlog of substantial-improvement reviews, and while a straightforward window replacement typically clears permitting without triggering elevation requirements, any job where windows plus other recent repairs approach 50% of assessed value needs careful scoping. We handle that conversation with the county so you don’t have to chase paperwork. If your home is on a canal lot and you’re also looking at exterior projects that touch the seawall line, like aluminum fence in Iona installations, coordinating the permit sequence early keeps both jobs moving.
For homeowners tackling broader exterior upgrades, window replacement often pairs naturally with a vinyl fence in Iona installation, especially when the old windows and fence were both damaged in the same storm season. And if you’re considering this as part of a whole-envelope upgrade, our windows and doors in Iona team can scope the full opening package so window specs and door specs match from the start.

Frequently asked: window replacement in Iona
Plan on two to four days for a full-home replacement, depending on the number of windows and whether we discover rusted lintels or water-damaged framing that needs repair. A ten-window job on a single-story concrete-block home usually wraps in two days. Each window takes 45-90 minutes to remove, prep, set, and seal. Our windows and doors crew protects interior floors and furniture on day one, and we don’t leave an opening exposed to weather overnight.
Yes. Iona is unincorporated Lee County, and the county requires a building permit for window replacement. We pull the permit, handle the inspection scheduling, and meet the inspector on site. The permit cost is included in your estimate, not tacked on later. If you’re replacing windows as part of post-Ian repairs that approach the substantial-improvement threshold, we’ll flag that before we start so you know exactly where you stand with the county.
You can, and we do partial replacements all the time in Iona. The most common pattern we see is replacing the west-facing and south-facing windows first, because those take the brunt of afternoon sun and storm-driven rain. We match the new window style and grid pattern to the existing ones as closely as the current product line allows. One thing to know: if you’re mixing impact and non-impact windows, your windstorm insurance discount typically only applies if every opening is impact-rated or has shutters.
The window manufacturer’s warranty covers the glass, frame, and hardware, typically 20 years to lifetime depending on the brand and product line. Our workmanship is covered by our 730-Day Done Right Promise: if something isn’t right, we make it right, no fine print and no runaround. In Iona’s coastal environment, we pay particular attention to sealant and flashing warranties because that’s where salt and UV exposure hit hardest.
It can, and we believe in telling you that upfront rather than surprising you mid-job. On Iona’s 1970s-1990s concrete-block homes, the most common hidden issue is a rusted steel lintel above the window that needs treatment or replacement. If we find one, we show you photos, explain what it means, and give you a written change order before we do a dollar of extra work. Most jobs come in at the estimated price because we build a reasonable contingency into our inspection process on the front end.
