We don’t open with a sales pitch because that isn’t what you’re here for. You’re looking at custom windows and doors because something about your Three Oaks home - the salt-air corrosion on the frames, the outdated single-pane glass that sweats in August, or the fact that a standard off-the-shelf unit won’t fit the opening left by Ian’s remodel - has forced the question. Custom means we build to your actual opening dimensions, your actual wind-load requirements, and your actual finish preferences. The price moves based on material, glass package, impact rating, and how many units we’re doing, and we’ll walk you through all of that before anyone picks up a tool.
How a Custom Windows & Doors Job Runs, Start to Finish
The process is straightforward, but it isn’t fast-food construction. Here’s how it goes, stage by stage, so you know exactly what to expect when you’re living through it.
1. On-site measurement and product selection (1-2 hours, one visit)
We come to your home, measure every rough opening to the sixteenth of an inch, and talk through your options face to face. This is where you’ll choose frame material, glass package, finish color, hardware style, and grid pattern if any. A background-checked, uniformed technician walks the whole house with you, notes any structural issues around existing openings - we see a lot of water-damaged sill plates in Three Oaks homes from the Ian cycle - and we build the quote from those real dimensions, not from a builder’s plan that may be years out of date. You’ll have your written price by the end of this visit.
2. Fabrication and permit pull (4-8 weeks, off-site)
Once you approve the order, we submit to the manufacturer and pull the permit with Lee County. Custom units are built to your specs - Andersen, Pella, or whichever line fits your budget and wind-zone requirements - and the lead time is what it is. No contractor can shorten a factory queue, and anyone promising 2-week custom windows in this market is selling you stock units with trim fillers. We track the order, keep you updated, and stage the install crew so we’re ready the week the units land.
3. Delivery and pre-install walkthrough (day 1, morning)
We inspect every unit on the truck before it comes off. Warped frame, cracked glass, wrong finish - it goes back, not into your wall. We walk you through what’s arriving, confirm placement, and set expectations for the next few days. If you’re living in the home during the install, we section the work so you always have at least part of the house sealed and climate-controlled overnight.
4. Installation (3-5 working days, sometimes longer for whole-home)
Old windows and doors come out, rough openings get inspected and repaired where needed - rotted framing gets cut out and replaced, not covered over - and new units go in with continuous flashing, foam-sealed jambs, and stainless fasteners rated for coastal exposure. Exterior trim gets caulked and painted. Interior casing goes back on. Our crew cleans up daily, not just at the end. For doors, we hang, shim, and adjust until the reveal is dead even and the weatherstripping seals tight with no daylight.
5. Final inspection, walkthrough, and close-out (last day, 60-90 minutes)
We do our own punch list first, then walk the job with you. Every window gets opened and closed. Every lock gets cycled. We check operation, finish, seal, and clean glass. You sign off when it’s right, not before. The 730-Day Done Right Promise starts the day we finish - if anything shifts, sticks, or leaks in that window, we fix it.
The Options You’ll Choose Between
Custom means you’re picking the spec, not settling for whatever the supply house had on the shelf. Here are the real choices and what they mean for your Three Oaks home.
- Vinyl frames. The most common choice and the best value. Today’s multi-chamber vinyl holds up well in our humidity, won’t rot, and costs less than wood or aluminum-clad. Color options are limited compared to painted wood, but the price difference is real - vinyl packages tend to land on the lower end of the $12,000-$35,000 range. Good for most homes where budget is the driver.
- Aluminum-clad wood. Wood interior for the look, extruded aluminum exterior to handle salt air and driving rain. This is what we recommend for higher-end homes in Three Oaks that need the architectural warmth of real wood casing. It costs more than vinyl and requires more care on the interior side, but the exterior aluminum skin takes decades of coastal exposure without pitting or fading the way raw aluminum does.
- Fiberglass. The best thermal performance of any frame material, period. Fiberglass expands and contracts at nearly the same rate as glass, so seals stay tight through 20-degree cold snaps and 98-degree August afternoons. Priced above vinyl, competitive with aluminum-clad wood, and an excellent match for homes where energy efficiency is the top priority.
- Impact-rated glass packages. In Three Oaks, this isn’t really optional. Florida Building Code 2023 mandates impact-resistant glazing or shutters in wind-borne debris regions, and most of Lee County qualifies. A laminated impact glass unit adds roughly 25-40% to the per-opening cost compared to non-impact, but you gain storm protection, break-in resistance, and a significant noise reduction. We spec the glass to your exposure - the wind-load calculation on a gable-end window facing west toward the Gulf is different from a sheltered east-facing opening.
- Low-E coatings and gas fills. Low-E reflects infrared heat, keeping your AC bill manageable from May through October. Argon or krypton gas between the panes improves the U-factor. In Southwest Florida, we prioritize solar heat gain coefficient over winter insulating value - you’re cooling your house nine months of the year, so the glass package should be tuned for that.
- Custom door configurations. Entry doors, French doors, bi-fold pass-throughs, oversized sliders. Fiberglass doors with a wood-grain texture hold paint well and don’t swell in humidity. Steel doors offer the best security rating but need diligent maintenance on the bottom rail in our climate - trapped moisture at the threshold is a rust point we watch for constantly.
When you’re ready to look at actual samples and pricing, we bring the catalog to your kitchen table. The written estimate breaks out frame, glass, hardware, and labor as separate lines - you see where every dollar goes, and the price you approve is the price you pay. Our upfront pricing, no surprises commitment means exactly that. We also offer 0% financing for 18 months and $1,000 off projects over $10,000, which takes some of the sting out of a whole-home window and door package.
What Custom Windows & Doors Costs in Three Oaks, FL
A full custom windows and doors project in Three Oaks runs $12,000-$35,000. Most homes with 12-18 openings land in the $16,000-$22,000 range for a mid-grade vinyl or fiberglass package with impact glass. Entry doors, sliders, and architectural shapes like arches or radius tops push the number higher. Here’s what moves it.
Number and size of openings. The single biggest cost driver. A 10-opening job is half the material and half the labor of a 20-opening job. Oversized units - picture windows, custom sliders, double entry doors - cost disproportionately more because the glass lite is larger and the frame requires reinforcement.
Frame material and finish. Vinyl is the value play. Fiberglass splits the middle. Aluminum-clad wood is the premium tier. Custom exterior colors beyond standard white or beige usually add a per-unit upcharge from the factory.
Impact vs. non-impact glass. Impact-rated laminated glass adds 25-40% per opening. In Three Oaks, nearly every permit we pull requires impact glazing or an approved shutter system - it’s not an upsell, it’s code compliance. If your home is in a wind-borne debris zone (which covers most of Lee County), the building department won’t sign off without it.
Existing opening condition. If the old window pulled out clean and the rough opening is square and dry, labor stays on track. If we find rotted king studs, termite damage, or water intrusion around the sill - common in Three Oaks homes that took Ian-driven rain into the wall cavity - the framing repair adds scope and cost. We show you photos of what we find and quote the fix before proceeding.
Permit and inspection fees. Lee County requires a building permit for window and door replacement when the opening size changes or when impact-rated units are part of a wind-mitigation upgrade. The permit cost is a line item on your estimate, not a buried markup.
Every estimate we write includes material, labor, fasteners, flashing, sealants, exterior trim, interior casing, debris removal, and the permit fee. What it does not include - and we tell you this upfront - is structural framing repair beyond a standard nail-on install, stucco repair beyond the immediate trim perimeter, or any electrical relocation if a door swing interferes with a switch. Those get addressed as separate line items if they come up.
What Three Oaks Homes Specifically Do to This Job
Three Oaks sits in Lee County, which was ground zero for Hurricane Ian’s 2022 landfall - the single most expensive hurricane to hit Florida in decades. Construction here is defined by an unprecedented post-Ian rebuild cycle, and that reality changes how custom windows and doors get specified, permitted, and installed in this specific market.
The concrete block suburban homes built here through the 1990s and mid-2000s present a consistent set of challenges. On older openings, we routinely find that the original window bucks were never properly flashed - just caulked and stuccoed over - and two decades of Southwest Florida’s heavy seasonal rains have worked moisture into the framing around the rough opening. When we pull the old unit, what looked like a straightforward swap sometimes reveals sill damage that needs carpentry before the new window goes in. We budget for that likelihood in our Three Oaks estimates, and our install crews carry pressure-treated lumber and stainless fasteners as standard truck stock because they use it on most jobs here.
The permitting reality is specific to this market, too. Lee County’s building department has been running a compressed timeline on post-Ian permits, and the 2023 Florida Building Code wind-mitigation requirements are enforced strictly. Impact-rated glazing is the norm, not the exception, and the product approval numbers on your new windows and doors need to match what’s on file with the county. We handle that end-to-end - the permit application, the NOA (Notice of Acceptance) documentation, and the final inspection with the county. Our technicians are background-checked and uniformed, and they know what the Lee County inspectors look for because they’ve stood next to them on hundreds of these jobs.
The Windows & Doors in Three Oaks work we do often pairs naturally with other exterior upgrades - homeowners tackling a full envelope improvement sometimes roll in Paver Driveways in Three Oaks or Concrete Driveways & Concrete Work in Three Oaks once the heavy equipment is already staged. It’s one less mobilization cost, and Three Oaks homeowners tend to think in terms of whole-property value, not one-off fixes. When the scope calls for it, our Windows & Doors division can coordinate with the site-work crew to sequence everything without stepping on each other.

Frequently Asked - Custom Windows & Doors in Three Oaks
Most whole-home jobs take 3-5 working days on site, not counting the 4-8 week fabrication lead time. A single door or a few windows can often be done in a day. The variables are the number of openings, how much framing repair we find, and whether we’re working around your family’s schedule - we can section the house so you’re never displaced from more than a few rooms at a time. Call (844) 638-7249 and we’ll give you a timeline based on your actual opening count.
Yes, if the rough opening size changes or if the new units are impact-rated and part of a wind-mitigation upgrade, which covers almost every custom windows and doors job in Three Oaks. Lee County requires a building permit with product approval documentation for each opening. We pull the permit, schedule the inspection, and stand with the inspector - you don’t handle any of that paperwork.
Not unless the scope changes. Our no-hassle upfront pricing is a fixed number based on what we measure and agree to before you sign. The one exception: hidden framing damage behind the old window that we couldn’t see until demo. If we open the wall and find rot, we stop, show you, and quote the repair as a separate line before we do anything else. You approve it or we don’t do it. The 730-Day Done Right Promise covers everything we install.
Usually, yes. We spec the new custom units to match the frame profile, finish color, grid pattern, and glass tint of what’s already there, provided the existing windows are from a manufacturer still in production or one with a close cross-reference. On older Three Oaks homes, exact matches aren’t always possible if the original line was discontinued, but we can get close enough that the difference isn’t visible from the curb. We’ll tell you honestly before you order whether it’ll be a dead match or a near match.
Two layers: the manufacturer’s warranty on the window or door unit itself - typically 10-20 years on vinyl and fiberglass, longer on the glass seal - and our 730-Day Done Right Promise on the installation workmanship. If a window sticks, a lock fails, or a seal opens up in the first two years, we fix it. Manufacturer defects beyond that window are handled through the factory warranty, and we facilitate that claim so you’re not stuck on hold with a corporate warranty department.
