Fast, Reliable Windows & Doors Across Sanibel
Replacing or installing windows and doors on Sanibel isn’t like doing the same job on the mainland. The salt air corrodes hardware faster, the post-Ian rebuild has flooded the island with materials and crews, and a single causeway controls when those materials can reach your job site. A typical window replacement in Sanibel runs $4,500-$15,000, and a full impact window package runs $8,000-$25,000. We’ll give you a written line-item quote before any work begins, and every price change arrives as a written change order before a single nail moves.

Why Barrett & Sons Construction Is Sanibel’s Preferred Windows & Doors Company
Thomas Barrett founded this company in 1998, and he still answers his own phone. On Sanibel, that matters more than it does almost anywhere else. You’ve been through enough since September 2022. The last thing you need is a national outfit that quotes one number on the phone and hands you a different bill when the truck pulls up. Tom publishes his name, his address, and his license number. Look them up before you sign anything. His sons run the crews, and a live person answers our phone 24 hours a day, seven days a week.
Sanibel homeowners tell us the same story repeatedly: the mainland contractor promised a price, then discovered the pile foundation requirements, then discovered the causeway bottleneck, then handed over a change order the size of a second mortgage. We don’t work that way. Every scope, every allowance, every price change lands on paper before work happens. The permit inspector works for you, not for me. That’s one reason we pull permits on every eligible job and stand beside the inspections.
We’re not the cheapest bid on the island, and we won’t pretend to be. We’re the crew that brings it in on the number we wrote down, installs Andersen or Marvin or PGT windows that you can look up yourself, and comes back if something isn’t right. That’s the 90-Day Done Right Promise, written on every contract in plain words.
Our Windows & Doors Services in Sanibel
Window Installation
New construction, whole-home replacement, or rebuilding after Ian, we handle window installation on Sanibel with hardware rated for this island’s salt air. We use hot-dipped galvanized or stainless fasteners on every exterior penetration, because standard zinc plate turns to rust dust in two or three years out here. We’ve worked from Gulf Shores to the bayside of Sanibel-Captiva Road, and we know which openings need impact-rated glass and which ones the code lets slide.

Door Installation
Entry doors, French doors, and hurricane-rated exterior doors all get the same treatment from our Windows & Doors team: correct flashing, corrosion-resistant hardware, and a level that stays level after the first wet season. On Sanibel, a door that isn’t properly sealed doesn’t just leak. It lets wind-driven rain inside the wall cavity, and then you’re rebuilding that wall eighteen months later.

Window Replacement
Most Sanibel window replacements we quote fall between $4,500 and $15,000, depending on how many openings, whether the frames are salvageable, and whether we’re working on a slab cottage or an elevated stilt home. If you’re in the 33957 zip code and your windows date to the 1970s, the frames are usually the first thing to go. We’ll tell you honestly whether you need full-frame replacement or if insert windows will hold up.

Impact Windows & Doors
Given what Sanibel went through with Ian, impact-rated windows and doors aren’t a luxury. They’re the difference between a home that rides out the next storm and one that loses its roof because the envelope breached. Impact window installation on Sanibel typically runs $8,000-$25,000 for a full home package. We work with PGT, Simonton, and CGI products, and we’ll show you the product approval numbers before we order anything. If you also need Hurricane Shutters, we handle those as well.

Trusted Brands We Service in Sanibel
We install Simonton, Ply Gem, and PGT windows and doors on Sanibel, and we stock common replacement parts on our trucks so a broken latch or roller doesn’t strand your home for two weeks while a part ships from somewhere in Pennsylvania. These are brands you can research yourself, with published wind ratings and salt-air performance specs. We won’t put a mystery brand in your home and call it premium. When you need impact-rated glass that meets current Florida Building Code 8th Edition requirements, we’ll quote the PGT or Simonton line, not a no-name knockoff off some distributor’s warehouse shelf.
Common Windows & Doors Problems We See in Sanibel Homes
- Salt-corroded hardware and rollers: The island’s persistent salt air eats standard zinc and aluminum hardware in a few seasons. Sliding doors that don’t slide, handles that snap off, and window cranks that rust solid are the most common service calls we run across Periwinkle Way, Middle Gulf Drive, and West Gulf Drive.
- Failed seals and fogged glass: Sanibel’s humidity and intense sun cycle glass seals hard. If you’ve got condensation between the panes, that’s a failed IGU, not a cleaning problem. Replacement IGUs are a fraction of a full window swap when the frame is sound.
- Improperly flashed post-Ian replacements: A lot of mainland crews flooded Sanibel after Hurricane Ian, did fast work, and left. We spend a lot of time correcting flashing jobs that leaked within a year because they were sealed for dry air, not hurricane-driven rain hitting the same opening for six hours.
- Elevation-driven fit and code problems: As homeowners elevate rebuilt homes to meet FEMA Base Flood Elevations, new doors and windows often need to sit higher than the original rough openings allowed. If you’re raising a home on piles and reusing old openings, those openings almost never line up with current code heights.
Pricing for Windows & Doors in Sanibel, FL
Here are the honest numbers for Sanibel’s market. Window replacement runs $4,500-$15,000 depending on opening count, frame condition, and glass package. Impact window installation runs $8,000-$25,000 for a typical island home. Full impact door packages, including a sliding glass door, usually land between $3,000 and $9,000. The two things that drive Sanibel pricing higher than mainland Lee County are the causeway logistics and the pile-elevation work most homes now require. You also have to account for the 45-foot island-wide height cap, and many residential overlay zones cap structures at 30 feet. When a homeowner raises a home to meet FEMA Base Flood Elevations, the finished floor often lands high enough that the roof pitch bumps into that limit. That’s a compliance trap that can add thousands if not caught early.

FAQs - Windows & Doors in Sanibel
Most Sanibel window and door estimates happen within three to five business days, but answer-now service depends on the workload heading into and out of storm season. The causeway adds variables no mainland shop faces, but our scheduling is always a phone call away at (877) 610-1318.
Yes. We serve every address in the 33957 zip code, from the Lighthouse Beach end near Periwinkle Way to the east-end neighborhoods along Middle Gulf Drive and the Captiva side of Blind Pass. Crews that say they won’t cross the causeway usually mean they don’t want to carry materials across it.
Three honest factors: every material truck crosses one causeway, almost every project now involves pile-elevation work, and the island’s flood zones and the Sanibel Land Development Code’s 30-to-45-foot height caps create tighter engineering constraints than mainland neighborhoods face. Those are real costs a mainland crew often doesn’t price until they’re already on the island. We price them up front.
Not without a written change order signed by you first. If rot, hidden structural damage, or a code-driven elevation adjustment changes the scope, we stop work, hand you the change order in writing, and let you decide. The 90-Day Done Right Promise starts when the job finishes, and it includes coming back to fix anything that wasn’t done right.
Yes. Every eligible job gets permits pulled and inspections signed. The permit inspector works for you, not for me. On Sanibel, where every rebuilt home now has to answer to FEMA, the Sanibel Plan, and Florida Building Code 8th Edition simultaneously, an unpermitted window or door opening can come back to bite you at resale or after the next storm.
Key Takeaways:
- Window replacement in Sanibel typically runs $4,500-$15,000; impact window packages run $8,000-$25,000.

- Post-Ian rebuilds face a single-causeway logistics chokepoint that mainland contractors rarely price correctly.
- Every Barrett & Sons job includes written change orders, permits pulled, and the 90-Day Done Right Promise.
- We also handle Fence Installation and Driveway & Pavers in Sanibel for your full exterior project.
