What You’ll Pay for Door Installation in Marco Island, and How Long It Actually Takes
Door installation in Marco Island runs between $900 and $10,500 for most single-door projects, with exterior and load-bearing work at the higher end. A straightforward interior door swap takes a day; framing a new opening, installing an exterior door, or reworking a wall can take two to four days. If you’re on the island today and want a firm number, call us at (844) 638-7249 for a free, written estimate that covers every line item.
What we see most often on the island isn’t a simple swap. It’s the door that won’t latch because the slab settled, the jamb that rotted from salt spray, or the hollow-core original that’s warped beyond saving after forty years of coastal humidity. Those are the real starting points for this work in Marco Island.
How We Handle Door Installation on the Island
Stage 1: The On-Site Walkthrough (Day 1, About 90 Minutes)
We come to your home, take measurements down to the rough opening, and check what’s behind the trim. In the 1965-1985 CBS homes that make up most of Marco Island’s original stock, we’re looking for corroded fasteners, sill rot, and slab movement. You’ll tell us what you need: are we replacing a door in the same opening, or cutting a new one? Exterior or interior? We talk through material choices and rough budget. By the end, you have a written, line-item estimate with no surprises later.
Stage 2: Permit and Opening Prep (When Needed)
If we’re cutting a new exterior opening or moving a wall, Collier County requires a permit, and the plans must show compliance with current wind-load and flood-elevation standards. We handle the submittal. For simple same-opening replacements, a permit isn’t always required, but we still follow the same code-grade practices. This stage typically adds a week to the timeline while paperwork processes.
Stage 3: Demolition and Rough Opening Repair (Day of Install, 2-4 Hours)
We pull the old door, casing, and jamb. In older Marco Island homes, this is where we often find hidden damage: rotted subsill from decades of salt-laden air, rusted anchors in the block, or framing that shifted as the engineered fill underneath settled. We take the opening back to sound material, repair or replace any compromised framing, and verify the rough opening is plumb, square, and level before the new door goes in.
Stage 4: Door Set, Shim, and Seal
The new pre-hung unit or slab gets set in the opening. We shim it precisely, anchor it to the block or framing with corrosion-resistant fasteners rated for coastal exposure, and check the reveal around all four edges. For exterior doors, we use a multi-layer flashing system and marine-grade sealants designed to hold up in barrier-island conditions. The door gets hung, the hardware goes on, and we test swing, latch, and weatherstrip compression before moving on.
Stage 5: Trim, Casing, and Final Walkthrough (Same Day or Day 2)
You pick the casing profile; we install it, caulk the seams, and touch up any paint. We vacuum the work area, walk you through the finished door, and show you exactly where to find the warranty paperwork. If it’s part of a full Windows & Doors in Marco Island project, we coordinate trim styles so everything reads as one house, not a patchwork.
The Decisions You’ll Make on Material and Configuration
Every door installation starts with a handful of choices. Here’s what we walk through, and what each option actually means in a Marco Island home:
- Interior solid-core vs. hollow-core. Solid-core doors weigh more, cost $200-$500 more per door, and block sound far better. In Marco Island’s 1,200-1,600-square-foot original floor plans, that matters, because bedrooms sit close to living areas. Hollow-core is lighter and cheaper, but it transmits noise and shows humidity warping faster in this climate.
- Exterior door material. Fiberglass stands up to salt air and direct sun better than steel and won’t rot like wood. Steel costs less but will eventually show rust at the bottom edge in this coastal environment, even with good weatherstripping. A wood door looks beautiful but demands annual sealing here. On Marco Island, fiberglass is our most common recommendation for west-facing or canal-front exposures.
- Pre-hung vs. slab replacement. A pre-hung unit includes the jamb and is the right call when the existing jamb is damaged or out of square, which is common in older CBS homes. A slab replacement keeps your existing jamb and saves labor, but only works if the jamb is solid and plumb. We’ll tell you which makes sense once we open it up.
- Impact-rated exterior doors. If you’re replacing an exterior door on a home built before the 2002 Florida Building Code, you may need an impact-rated assembly to meet current wind-borne debris requirements. These start around $1,800-$4,000 for the unit alone, but they’re non-negotiable for permitted work on many Marco Island homes. Our Windows & Doors crews install Andersen and Pella impact-rated doors regularly, and we’ll spec the right one based on your exposure.
- Locksets and hardware finishes. Choose a finish rated for coastal use: stainless steel or a high-grade powder coat. Standard brass and oil-rubbed bronze hardware pit quickly in the salt air here. We specify hardware from brands like Schlage and Baldwin with documented salt-spray ratings.
What Door Installation Costs in Marco Island, FL
In Marco Island, a single interior door replacement on an existing opening starts around $900 and rarely exceeds $2,400, including the door, hardware, trim, and labor. Exterior door installation runs $2,800 to $10,500, depending on impact rating, custom sizing, and how much rot repair the rough opening needs.
Five things push the price toward the top of that range:
- Impact-rating requirements. An impact-rated fiberglass entry door with a full glass lite and multi-point lock system costs three to five times what a standard non-impact unit costs. That’s not markup, it’s the cost of a door engineered to take a 2×4 at 34 mph without breaching.
- Rough opening condition. In 40-to-60-year-old Mackle-era homes, we routinely pull the trim and find a rotted sill plate or corroded anchor straps. Rebuilding the threshold and subsill can add $400-$1,200 in labor and materials on the spot.
- Slab settlement correction. If the floor has dropped a half-inch at the doorway relative to the jamb, the door will never hang right until we address it. Minor shimming is part of the job; significant re-leveling isn’t, and it adds cost.
- Opening a new doorway. Cutting a new opening in a CBS wall requires a structural header, a permit, and coordination with any electrical or plumbing in that wall bay. These projects start at $3,200 for interior and $5,800 for exterior, and they run higher fast in Marco Island’s older block homes.
- Custom sizes and sidelites. A standard 36-inch door is off-the-shelf. A 42-inch entry door with sidelites is a custom order with a longer lead time and a 40-70% price premium. On the luxury rebuilds happening across the island, custom entry systems are the norm, not the exception.
Every estimate we write includes the door unit, hardware, trim, labor, debris removal, and any permit fees we handle on your behalf. What it doesn’t include is the unknown rot behind the jamb, but we’ll show you a photo before we do any work that changes the price. Call (844) 638-7249 and we’ll come out and give you a real number. Some Marco Island homeowners do the door at the same time they do a Vinyl Fence in Marco Island or Chain Link Fence in Marco Island, and we can bundle the estimate to save you time.
What Door Installation Looks Like Specifically in Marco Island
The homes we work on here trace back to a mid-1960s development boom, when the Mackle Company graded tidal flats into buildable lots and put up thousands of single-story CBS homes. They built them light, fast, and with materials that were never meant to see 2026. The original interior doors on these houses are almost always hollow-core lauan, and by now the bottom rails have swollen from forty humid summers, the hinge screws have stripped out of the soft blocking, or the slab has shifted enough that the latch no longer catches.
Exterior doors are a different problem: salt-laden Gulf air corrodes anything ferrous. We’ve pulled entry doors near the Snook Inn area where the bottom six inches of the steel jamb were essentially gone, replaced by rust scale and caulk from three previous owners. On canal-side homes near the Holiday Inn Club Vacations Sunset Cove Resort, afternoon sun and reflected water heat load cause fiberglass skins to delaminate over time if they weren’t grade-one units to begin with. And on the teardown-rebuild lots popping up along streets feeding toward Wheel Chair Only Beach View, the question is rarely about replacing a door. It’s about framing the rough openings correctly on a new elevated build where the subfloor is 12 to 16 feet above the fill, and the wind loads demand strapping and anchors that a standard tract-home door jamb was never designed to carry.
The common thread: in Marco Island, every door installation has to account for salt, settlement, and wind code. Nothing about this job is exactly like doing it inland. That’s why we keep background-checked, uniformed crews on these jobs who know the local conditions, and why we back every installation with our 730-Day Done Right Promise: if something isn’t right, we make it right.

Frequently Asked Door Installation Questions in Marco Island
A simple interior door swap in an existing opening takes one day, start to finish. Exterior door installation or new-opening work typically takes two to four days. If a permit is required, expect about a week of lead time before we begin. Our Marco Island schedule can usually accommodate most jobs within two weeks of estimate approval, depending on material lead times for custom or impact-rated doors.
Not for a same-size replacement in an existing opening, in most cases. But if you’re cutting a new exterior opening, widening a doorway, or installing a new exterior door on a home subject to the Florida Building Code’s wind-borne debris requirements, yes, a Collier County permit is required. We handle the determination and the paperwork so you don’t have to guess.
Yes, and it’s the most common job we do. If the rough opening is sound, we can pull the old jamb and set a new pre-hung door without touching the surrounding wall. If the opening has shifted or rotted, we repair just the affected area, not the whole wall. A true new-opening job is a different scope, and we’ll tell you upfront which one you need.
A standard single exterior door replacement runs $2,800-$6,500. A high-end fiberglass impact-rated door with sidelites can reach $10,500. The biggest variables are whether the door must be impact-rated, the condition of the rough opening, and whether you’re on a canal or direct Gulf exposure where hardware and sealant upgrades are advisable.
The door manufacturer warrants the unit itself, and Groundwork Construction Co. covers the installation labor under our 730-Day Done Right Promise. If a door we installed starts sticking, won’t latch, or shows a defect in our workmanship within two years, we come back and fix it. Doors in coastal conditions will require maintenance, but installation failures are on us.
