AfterFast, Reliable Door Installation Across Sanibel
Door installation in Sanibel runs $1,800-$6,500 for a standard entry door with impact glass, and $4,000-$12,000 for French or double door systems. Most jobs are completed in one to two days once your units arrive from the fabricator. If you’re on the island and need a door that will actually hold up to salt spray, storm surge, and a building department that checks every detail, call TruePane Windows & Doors at (239) 323-5522. We measure twice, quote in writing, and stand behind the work with a 90-Day Done Right Promise.
Sanibel isn’t like working on the mainland. We deal with the Causeway delivery schedule, HVHZ wind zone requirements, and homes that were rebuilt from the studs after Hurricane Ian. Every door we hang here is treated as a coastal impact installation, not a simple swap.

Why TruePane Windows & Doors Is Sanibel’s Preferred Door Installation Company
We’ve been working on Sanibel long enough to know that the island builds differently. The salt spray off the Gulf and Pine Island Sound eats standard aluminum frames within three to five years. Wind-driven rain finds every weak point at the threshold. And the building department won’t sign off on anything that doesn’t carry the right product approval numbers for Lee County’s HVHZ zone. Our Door Installation team arrives on the island knowing all of this before we step out of the truck.
Dale Kessler founded this company on a simple rule: if the pane is not true, the job is not done. That standard applies to every door we hang on Sanibel, from a single entry replacement off Periwinkle Way to a full set of French doors on a rebuilt stilt home near Bowman’s Beach. We register both manufacturer warranty layers in writing, we state the durations on your quote, and we honor a 90-Day Done Right Promise with no paperwork fights.
Our technicians are background-checked, uniformed, and local to Southwest Florida. A live person answers our phone 24 hours a day, seven days a week. When you call about a door that’s binding or a threshold that’s leaking after a storm band rolls through, you talk to a person who knows Sanibel, not a call center in another state.
Our Door Installation Services in Sanibel
Hurricane-Proof Front & Entry Doors
Every front door on Sanibel should carry a Miami-Dade NOA or Florida Product Approval with a large-missile rating. That’s not an upgrade here – it’s the baseline. We install impact-rated entry systems from PGT, CGI, and Therma-Tru with laminated glass interlayers and stainless-steel hardware that won’t seize up in salt air. Our installs on Sanibel include marine-grade butyl flashing at the flange and a powder-coated aluminum sill pan, because wind-driven rain at the threshold is the failure point we see most often on island homes.
Storm & Exterior Doors
A storm door on Sanibel does double duty. It’s a first line of defense against wind-driven rain during summer squalls, and it buys time for your impact-rated entry door behind it. We install storm doors with corrosion-resistant hardware and frames built for three-sided salt exposure. If you’re on the east side of the island near Dixie Beach Boulevard, you’re catching spray off Pine Island Sound as well as Gulf storms – your exterior door hardware needs to be solid stainless or brass, never plated steel.
Replacement Doors
Replacing a door on an older Sanibel home usually means more than pulling the slab and hanging a new one. The original jamb may be rotted from years of salt spray and wind-driven rain. The rough opening may not meet current design pressure requirements. We inspect the framing before we quote, and we write any structural repair into the contract as a line item – not a surprise change order later. On post-Ian rebuilds, we’re often working on fresh rough openings in brand-new stilt framing, which lets us set the door to current code from day one.
French & Double Doors
French doors on Sanibel need to do two things at once: look right on a beach cottage or a rebuilt coastal contemporary, and hold a large-missile impact rating. That means heavier frames, laminated glass on both panels, and hardware that won’t corrode from salt air coming off the Gulf. We install French and double door systems that meet Florida Building Code extreme-wind specs for Sanibel’s HVHZ zone. Lead times run longer than mainland Lee County jobs because oversized slabs have to cross the Sanibel Causeway on a scheduled wide-load run, not a standard delivery truck.

Trusted Brands We Service in Sanibel
We’re an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, Marvin, Milgard, PGT, and CGI. For Sanibel specifically, we lean on PGT, CGI, and ViewLux impact-rated products because they carry the Miami-Dade NOA and Florida Product Approval numbers that Lee County inspectors expect here. We quote manufacturer lines side by side on paper so you see exactly what you’re buying – the glass package, the frame finish, the design pressure rating, and the warranty terms.

Common Door Installation Problems We See in Sanibel Homes
- Rotted jambs from wind-driven rain. Standard flange tape breaks down under Sanibel’s salt spray within a few seasons. Water gets behind the trim, the jamb rots, and the door starts binding at the threshold. We reframe and flash with marine-grade butyl tape and a powder-coated sill pan.
- Pitted and oxidized aluminum frames. Off-the-shelf coastal aluminum isn’t built for three-sided salt exposure. Frames pit within a few years, hardware seizes, and air leaks develop at the sill. We specify heavy-duty anodized or marine powder-coated frames for every Sanibel installation.
- Non-impact doors failing final inspection. After Hurricane Ian, rebuilt stilt homes on Sanibel are under strict code enforcement. A non-impact exterior door without the right product approval triggers a stop-work order. We handle permitting and product approvals as part of the job.
- Threshold leaks on elevated homes. Wind-driven rain on an elevated stilt home hits the door at a different angle than on a slab-on-grade. The threshold interface is where we see the most failures. Our flashing detail includes a sloped sill pan that directs water away from the rough opening.
Pricing for Door Installation in Sanibel, FL
Here’s what we see on Sanibel right now. A standard impact-rated entry door with Miami-Dade NOA runs $1,800-$4,200 installed, depending on glass package and frame finish. A premium fiberglass entry system like a Therma-Tru with laminated glass and stainless hardware runs $3,500-$6,500. French doors with impact glass start around $4,000 and can hit $12,000 for wide custom openings with structural header work. If the permit inspection opens up a wall and finds undersized framing or outdated wiring that has to be brought to code, that work gets priced and approved in writing before we touch it. Call (239) 323-5522 for a free in-home measure and a written quote with every line item spelled out.
What Door Installation Costs in Sanibel
The biggest cost drivers on Sanibel are impact rating requirements, frame material for salt exposure, and what we find when we open the wall. A basic impact single door might run $1,800-$3,000. A large custom opening or a French door system runs $4,000-$12,000. Whole-home door packages – say, a front entry, a rear slider, and two exterior doors – typically land between $8,000 and $25,000 depending on product lines and framing condition. Floor height matters too: an elevated stilt home off Sanibel-Captiva Road needs different flashing and sill details than a ground-level cottage near Lighthouse Beach. Our quotes are written line by line, and the price we quote is the price you pay unless you approve a change in writing first.
The best way to get a real number is to have us measure. Call (239) 323-5522 and we’ll schedule a free in-home assessment. You’ll get a written quote with manufacturer line items, warranty durations, and a permit allowance – no vague estimates, no pressure.
Florida Pays You Back
Sanibel homeowners have access to a stack of incentives that can take a serious bite out of a door installation bill. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact-rated doors count. Florida also exempts impact-resistant windows and doors from sales tax, which on a $6,000 door system saves you hundreds. The federal 25C energy credit applies to qualifying energy-efficient doors at 30% of product cost, up to $600 per year. After a wind-mitigation inspection ($75-$150), many Sanibel homeowners see windstorm premium credits averaging around 25% on the windstorm portion of their policy. Programs and carriers set the final numbers – we don’t promise a specific discount – but we’ll help you document everything for your application.
One comparison worth making: impact doors versus hurricane shutters. Shutters only protect you if someone is home to hang them, and they do nothing for day-to-day security or energy efficiency. Impact doors are permanent protection. No panels to store, no hardware to fight with when a storm is 48 hours out, and they work every single day of the year. We don’t sell or install shutters, but we’ll explain the difference honestly if you’re weighing both options.
What Opening an Older Sanibel Home Actually Turns Up
Here’s the part nobody tells you until the permit is pulled and the wall is open. On a Sanibel home built before the 1990s, a door replacement often reveals outdated wiring that has to be brought to code because the inspector is now looking at that wall cavity. The original framing may be undersized for current design pressure requirements. The waterproofing at the rough opening may have failed years ago, and what looked like a simple door swap is now a structural repair. This is the single biggest reason a Sanibel door quote moves during construction.
Our approach is inspection first, allowances written into the contract, and any surprise priced and approved in writing before we touch it. We don’t spring change orders on you after the wall is open. We tell you what we might find, we write a realistic allowance for it, and we show you photos of what we found before we ask for approval on anything beyond the original scope. That’s how we’ve handled every Sanibel job since the post-Ian rebuild started, and it’s why homeowners on the island keep our number.
On a stilt home off Periwinkle Way rebuilt after Hurricane Ian, our crew installed a Therma-Tru fiberglass entry door with a laminated glass interlayer and stainless-steel hinges. The original 1970s jamb had rotted from wind-driven rain at the threshold, so we reframed the rough opening to current design pressure, then flashed the flange with marine-grade butyl tape and a powder-coated aluminum sill pan before hanging the new unit. The homeowner’s wind mitigation inspection passed without a single correction.
What Makes a Sanibel Door Different
Unlike mainland Fort Myers or Cape Coral, every door installed on Sanibel must carry Miami-Dade NOA or Florida Product Approval with a large-missile rating. The island sits in an HVHZ zone with unobstructed Gulf storm bands and three-sided salt spray that pits standard coastal aluminum within a few years. This isn’t a recommendation – it’s what Lee County code requires, and it’s what your insurance carrier will ask about when you file for windstorm premium credits. We specify heavy-duty anodized or marine powder-coated frames and solid stainless or brass hardware on every Sanibel installation. No exceptions.
Delivery is another Sanibel-specific wrinkle. The island is accessible only via the single Sanibel Causeway. Oversized impact-glass door slabs and French door units can’t just roll over on a standard box truck. They require pre-scheduled wide-load flat-bed runs, and the narrower interior roads east of Tarpon Bay add coordination time. That’s why lead times run longer for Sanibel deliveries than for Fort Myers or Estero jobs. We build that into our schedule up front and tell you the reality before you sign.

Our crews work across Lee County, including Fort Myers Beach, Cape Coral, Estero, and Fort Myers.

FAQs - Door Installation in Sanibel
Because Sanibel is in an HVHZ wind zone, and Lee County code requires every exterior door to carry Miami-Dade NOA or Florida Product Approval with a large-missile rating. The permit inspection also triggers code review of whatever the inspector can see inside the wall cavity – wiring, framing, waterproofing. If the opening needs structural work to meet current design pressure, that’s a separate line item. We write the permit allowance into your quote up front so you’re not surprised. Call (239) 323-5522 for a written quote that spells out every line.
A Sanibel-grade door has a Miami-Dade NOA or Florida Product Approval with large-missile impact rating, a heavy-duty anodized or marine powder-coated frame, and solid stainless or brass hardware. Standard coastal aluminum sold for mainland Lee County won’t survive three-sided salt spray for more than a few years. The glass package matters too – laminated interlayers, not just tempered glass. That’s what we specify on every Sanibel job.
Usually not on older Sanibel homes. Wind-driven rain at the threshold rots jambs from the inside out, and once the slab is off, the damage is often worse than it looked. If the original framing doesn’t meet current design pressure for the opening size, code requires reframing before we can hang the new unit. We inspect first and tell you what’s actually needed – and we don’t recommend reusing a jamb that’s been soaking up salt spray for thirty years.
Oversized impact-glass French door units can’t cross the Sanibel Causeway on a standard delivery truck. They require scheduled wide-load flat-bed runs, and the island’s narrower interior roads add coordination time. Custom fabrication at the manufacturer typically runs four to six weeks regardless of where you live. Add a week or so to that for Sanibel logistics. Call (239) 323-5522 and we’ll give you a realistic timeline with the lead time built in.
After a wind mitigation inspection – usually $75-$150 – your carrier can apply windstorm premium credits for impact-rated doors and windows. The average credit runs around 25% on the windstorm portion of the policy, though the final number depends on your carrier and your home’s overall mitigation features. Impact doors with documented Miami-Dade NOA or Florida Product Approval are exactly what insurance underwriters look for on a barrier island like Sanibel. We’ll provide the documentation your inspector needs.
