Custom Windows & Doors in Iona, FL Runs on Specifics - Here’s What to Budget and Expect
Custom windows and doors in Iona typically run $8,000-$25,000 for a full-home package, and most jobs finish inside two to six weeks, depending on whether you’re replacing existing openings or cutting new ones. Every project gets its own load of shop drawings, factory lead times, and Lee County permit reviews before the first piece of glass shows up.

How a Custom Window and Door Job Actually Goes in Iona
Most homeowners have never ordered a custom door or a full set of windows built to their opening dimensions. The process is more detailed than picking a stock unit off a shelf, and the timeline depends heavily on whether we’re working with existing rough openings or reframing something entirely new. Here’s what the five stages look like from start to finish.
Stage 1 - On-site measure and selection. We come to your Iona property with sample kits, finish swatches, and our full line cards from Andersen, Marvin, and Pella. We measure every opening down to the eighth of an inch and document the existing framing condition, the exterior cladding, and any water-intrusion signs common in 1970s-1980s canal-front CBS homes. This visit takes about 90 minutes, and by the end of it you’ll have a written, line-item quote with material grades, glass packages, hardware finishes, and the structural scope spelled out.
Stage 2 - Shop drawings and permit submission. Once you approve the scope, our design team turns the field measurements into manufacturer-ready shop drawings. For custom doors, that includes hinge locations, threshold details, and swing direction. For windows, it includes egress compliance and impact-zone ratings. At the same time, we submit the permit package to Lee County - and because Iona sits in the Hurricane Ian rebuild corridor, the county checks flood-zone compliance, substantial-improvement thresholds, and wind-load calcs before stamping approval. This stage typically adds two to four weeks, mostly waiting on the county review queue.
Stage 3 - Fabrication lead time. Custom units are not sitting on a shelf. Once the shop drawings are approved, the manufacturer cuts the frames, builds the glass packages, and assembles the units to your exact dimensions. Depending on the brand and the volume of openings, fabrication runs three to eight weeks. We’ll give you a firm window at contract signing and won’t cut the existing openings until the units are physically at our Fort Myers warehouse.
Stage 4 - Installation days. On install day, our crew arrives in uniform with background-checked technicians who’ve done this in Iona’s concrete-block homes hundreds of times. We remove the existing units, repair any rotted buck framing or water-damaged jambs, flash the new openings to current Florida Building Code, and set each unit, insulating and sealing as we go. For a full home of windows plus a custom entry door, plan on three to five working days. We tarp and protect every opening at the end of each day - afternoon thunderstorms roll in fast off the Caloosahatchee and we don’t gamble with exposed framing.
Stage 5 - Trim, finish, and walkthrough. After the units are set, we install interior and exterior trim to match the style you chose, caulk every seam with marine-grade sealant, and clean every pane of glass inside and out. We walk the job with you, test every operable unit, and hand you the warranty registration paperwork. If anything isn’t right, you call the same number that answered the first time - (844) 638-7249 - and our 730-Day Done Right Promise means we fix it, no back-and-forth.
What You’re Choosing When You Order Custom Windows and Doors
Custom doesn’t mean infinite - it means the unit is built to your opening, not the other way around. But you still pick the material, the glass, the finish, and the hardware. Here are the real decisions and the honest trade-offs for each.
- Frame material - vinyl, wood, fiberglass, or aluminum. Vinyl gives you the best cost-to-performance ratio and never needs painting, but in dark colors it can warp under direct Florida sun. Wood offers unmatched warmth and can be painted or stained any color, but it requires maintenance in Iona’s humid, salt-air canal environment. Fiberglass is the premium play - it expands and contracts at nearly the same rate as glass, so seals stay tight for decades, and it handles dark colors without warping. Aluminum is strong and slim-profiled but conducts heat, so we spec it only with a full thermal break in coastal applications.
- Glass package - single-pane, double-pane, or impact-rated. Single-pane is code-compliant in some non-bedroom applications but makes no sense in Iona’s climate. Double-pane insulated glass with Low-E coating cuts your cooling load noticeably. Impact-rated laminated glass is required for any opening in the wind-borne debris zone, and in Iona - much of which falls inside that zone - it’s the right call even where the code lets you opt out. The price jump is real, but so is the insurance discount.
- Custom door configuration - single, double, sidelites, transoms. A single custom entry door starts simpler, but many Iona homeowners rebuilding post-Ian are widening the front entry and adding sidelites or a transom to pull more natural light into the living space. If your slab elevation was raised during a post-storm rebuild, we often build custom-height doors to match the new finished floor elevation without awkward step-downs.
- Hardware and finish. Hinges, handlesets, multipoint locks, and finish color are all specified per opening. In a salt-air environment like the Iona canals, we recommend marine-grade stainless steel or powder-coated finishes rated for coastal exposure. Standard hardware will pit within three years out here.
- Interior wood species and exterior cladding. If you go wood or wood-clad, you choose the interior species (oak, maple, pine, fir) and the exterior cladding (extruded aluminum or vinyl). We steer most Iona customers toward extruded aluminum cladding on the exterior side - it laughs at salt spray - with a clear-finished wood interior that stays protected behind the glass.
What Custom Windows and Doors Cost in Iona, FL
A full package of custom windows and doors in Iona lands between $8,000 and $25,000 for most single-family homes. The variables that push a project toward the low or high end of that range are specific and measurable, not vague. Here’s what drives the number.
Number of openings. A 1,200-square-foot ranch with eight windows and one entry door runs toward the lower end. A two-story canal-front home with eighteen openings, three sliding glass doors, and a custom double entry door with transom pushes past $20,000 fast. Every additional opening adds material cost, flashing labor, and a permit line item.
Impact versus non-impact. Impact-rated laminated glass costs roughly 40-60% more per square foot than standard double-pane insulated glass. In Iona’s wind-borne debris zones, going non-impact can save money upfront but may disqualify you from insurance wind-mitigation credits - and a lot of our customers on the canals have already learned that lesson the hard way during Ian.
Existing framing condition. When we pull the old windows on a 1980s CBS home, we often find rotted wood bucks, corroded anchors, or termite damage in the jamb framing. Replacing the buck and re-anchoring the rough opening adds $150-$400 per opening, depending on scope. We show you photos of what we find before we do any extra work - upfront pricing means we quote the fix before we pick up a tool.
Custom door complexity. A standard single entry door with one sidelite is far simpler than an 8-foot iron-and-glass pivot door with a curved transom. The latter requires engineered headers, steel reinforcement, and sometimes a structural review by a Florida-licensed engineer. We handle it, but the engineering and fabrication costs add $2,000-$5,000 to the door line item alone.
Permit and inspection scope. Lee County permit fees for window and door replacements are relatively straightforward when we’re swapping like-for-like in existing openings. If we’re cutting new openings or enlarging existing ones, the scope triggers plan review, wind-load calculations, and possibly a floodplain review if your property falls in a special flood hazard area. We build the permit fees into your written estimate so you see the number on page one.
Every estimate we write includes the material cost, the labor, the permit fees, the flashing and sealants, the interior and exterior trim, and the warranty registration. What’s typically not included - and we flag this at the estimate table - is drywall repair on the interior beyond the immediate trim zone, repainting existing walls beyond the new trim, or any electrical relocation if a window interferes with an outlet. Call (844) 638-7249 and we’ll walk your property, measure every opening, and hand you a fixed-price quote before we leave the driveway.
What Iona Properties Do to a Custom Window and Door Job
Iona’s housing stock is predominantly 1970s-to-1990s concrete-block construction on slab, much of it built at original grade elevations that now sit below current Base Flood Elevation requirements. When we measure for custom windows and doors on these homes - especially along the finger canals off the Caloosahatchee - we’re often working with slab heights that leave very little room between the finished floor and the bottom of the rough opening. A custom door built to modern flood-compliance heights sometimes requires us to notch the slab elevation into the quote and coordinate with a concrete crew. Homeowners often pair this work with updated Concrete Driveways & Concrete Work in Iona or a full Paver Driveways in Iona project when they’re already re-grading the lot for drainage.
Permitting runs through Lee County, not a municipal building department, which means every permit package hits the same review queue that’s been backlogged with Ian-related substantial-improvement reviews since late 2022. We time our submissions and track them daily - we know the reviewers by name - but homeowners should plan for a two-to-four-week wait on the permit stamp. On canal-front lots where the seawall was damaged or replaced post-Ian, Lee County sometimes requires a seawall certification letter before issuing the building permit. We flag that early and help you coordinate the marine engineer if needed. None of this surprises us anymore, but it catches out-of-area crews off guard every time - and a delayed permit in Iona can push an October start date right into the holiday season.
When you’re ready to price custom windows and doors on your Iona home, this is part of a larger Windows & Doors in Iona conversation - and our Windows & Doors crew handles the full scope from measure to trim.

Frequently Asked - Custom Windows and Doors in Iona
From the day you sign the contract to the final walkthrough, plan on six to twelve weeks. About two to four of those weeks are Lee County permit review, three to eight are manufacturer fabrication, and three to five working days are installation. The biggest variable is the permit queue - we can’t control the county’s review speed, but we can file a clean, complete package the first time so it doesn’t bounce back for corrections.
Yes. Lee County requires a building permit for window and door replacement, even when you’re swapping like-for-like in existing openings. If we’re enlarging openings or cutting new ones, the permit triggers a full plan review with wind-load calculations and possibly a floodplain check. We pull the permit as part of the job - you never have to visit the county building department yourself. Call (844) 638-7249 and we’ll explain exactly what your specific scope triggers.
In Iona, this is the single most important question post-Ian. The 50% rule applies to the cumulative cost of improvements over a five-year rolling window, measured against the assessed structure value. Window and door replacement alone rarely hits that threshold, but if you’ve already done a roof, siding, or electrical upgrade since Ian, we’ll help you run the numbers before we pull the permit. We can’t change the rule, but we can make sure you understand exactly where your property stands before committing to a scope.
The manufacturer warranty on the units themselves varies by brand - Andersen, Marvin, and Pella all carry 10-to-20-year limited warranties on glass and frame components, with specific terms on the finish and hardware. On top of that, Groundwork Construction Co. backs every installation with our 730-Day Done Right Promise: if something isn’t installed correctly, we fix it, no deductible and no runaround. You register the manufacturer warranty at the walkthrough, and our labor warranty is already in writing in your contract.
We install, trim, and caulk every opening - the interior trim is part of the job and we match the style and profile you choose at the estimate visit. We do not paint the existing wall beyond the new trim, and we don’t patch drywall outside the immediate trim zone unless we’ve scoped it into the estimate. If the old window had a wider casing than the new one and you need drywall touch-up, we’ll flag that before we start and you can decide whether to add it to the scope or handle it with your own painter.
