Impact window and door replacement in Big Coppitt Key typically runs $1,200-$2,800 per opening installed, depending on size, product line, and what we find inside the wall when we open it. Most full-home replacements here land between $18,000 and $42,000 before any framing corrections the permit triggers. Call (754) 238-2201 and we’ll give you a written line-item estimate based on your actual openings, not a phone-bid guess.
We work Big Coppitt Key regularly, from the elevated pilings homes along Avenue B and Avenue F to the post-Irma rebuilds closer to the old Coppitt bridge. We know the salt spray eats hardware faster here than manufacturer coastal timelines suggest, and we know Monroe County code does not let you skate by with standard windows and shutters. That local knowledge keeps your quote honest and keeps the job from stalling at inspection.
Why TruePane Windows & Doors Is Big Coppitt Key’s Preferred Impact Windows & Doors Company
TruePane Windows & Doors has served Florida homeowners since 2008, founded by second-generation glazier Dale Kessler on a rule that still names the company: if the pane is not true, the job is not done. We’re not a franchise operation cycling through subcontractors. We hire local, train apprentices into journeymen, and act like a company that plans to be in town in thirty years. Dale still answers the phone some days. A live person answers every day, 24/7, not a voicemail tree.
What Big Coppitt Key homeowners tell us they value most is the Impact Windows & Doors team’s approach to the wall itself. We don’t measure from the outside and quote a number. We inspect the rough opening, check what’s behind the flange, and tell you before you sign whether your framing will meet the 180 mph wind-speed rating Monroe County enforces. Every job carries the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves the driveway. No paperwork fights, no arguing.
Our technicians are background-checked and uniformed. They measure every opening twice and quote manufacturer lines side by side on paper, so you see exactly what you’re buying. We’re an authorized installer for more than a dozen manufacturer lines, including, PGT, CGI, and ES Windows. When something goes wrong, we’ll be there when we say. That’s a square deal, not a slogan.
Our Impact Windows & Doors Services in Big Coppitt Key
Hurricane Impact Windows
A single hung impact window in Big Coppitt Key runs $1,100-$2,400 installed. Casements and picture windows push toward the higher end because of size and hardware. On older Irma-survivor homes, the bigger cost variable is what sits behind the old frame. Pre-1990s concrete-block homes here often lack structural headers or have king studs undersized for current uplift math, which means the permit triggers a framing correction before the window goes in. We write that allowance into the contract up front, so you’re not surprised when the wall is open.

Impact Sliding Glass Doors
Impact sliding glass doors in Big Coppitt Key run $3,800-$8,500 installed. Elevated homes complicate the work because the deck sits up to 10 feet above grade, with saltwater on both the Atlantic and Florida Bay sides of the island. A slider threshold on a pilings home needs positive drainage and marine-grade stainless fasteners, or you’ll be replacing a rotted sill within three seasons. We flash these openings the way Monroe County requires, not the way a mainland crew might assume.

Impact Entry & French Doors
Entry and French door replacements in Big Coppitt Key run $2,600-$6,200 per door, depending on whether we’re setting a single panel or a pair. Elevated thresholds are the recurring failure point here because wicking saltwater corrodes standard hardware fast. We spec stainless or marine-grade hardware on every door that faces open water, which on this island is nearly every door. It’s not an upgrade line item; it’s the only correct spec.

Impact Garage Doors
Impact-rated garage doors in Big Coppitt Key run $3,200-$7,000 installed for a double-wide, track and hardware included. Post-Irma rebuilds often left the garage door as the last weak opening, and a non-rated door will fail a wind mitigation inspection. We replace the panel and the track as a matched system because a new impact panel on old hurricane hardware is a false sense of security. The rating is only as good as the weakest anchor.

Common Impact Windows & Doors Problems We See in Big Coppitt Key Homes
- Moisture between glass in new impact units after two or three years. We see this most often on homes where a previous contractor reused corroded aluminum frames or installed units over old furring strips without removing rotten sheathing. The trapped moisture fails the seal and voids the manufacturer’s wind-load warranty. Replacing the sash isn’t enough; the rough opening has to be reconditioned.
- Elevated door thresholds wicking saltwater into the jamb. Big Coppitt Key sits narrow with open saltwater on both sides, so there’s no leeward face. Salt spray hits every elevation year-round. Standard screws and untreated flashing corrode fast. We replace with marine-grade stainless and positive drainage, and the problem stops recurring.
- Pre-Irma framing missing structural headers or undersized king studs. We find this on almost every older concrete-block home we open. The building met code in 1993 but doesn’t meet current 180 mph uplift requirements. Monroe County won’t sign off on the window replacement without the framing correction, so we write that into the original quote rather than springing it later.
- Failed wall waterproofing around impact window flanges. On homes close to Avenue B near the old Coppitt bridge, years of wind-driven salt rain works behind the flange if there’s no flashing tape or if the old sheathing was left in place. The fix is cutting back to sound framing and re-cladding to current code before the new window is set. Skipping that step means the same failure returns.

FAQs - Impact Windows & Doors in Big Coppitt Key
You’ll likely need framing corrections before the new impact window goes in. Pilings homes built before the 2017 hurricane often have king studs and headers that don’t meet Monroe County’s current 180 mph uplift requirements. When we open the wall, we inspect the rough opening and tell you exactly what the code requires. We write that allowance into the contract before we start, so the number on your quote is the number you pay. Call (754) 238-2201 for a wall-by-wall assessment.
No. Monroe County does not allow non-impact windows paired with removable shutters as a code-compliant strategy for new or replacement openings in this wind zone. Every window and door swap on Big Coppitt Key must be a fully rated impact product. Contractors who show up with a shutter-plus-standard-window plan will fail inspection and leave you with a job that can’t be closed out. We only propose what passes.
The most common cause is installation over rotted sheathing or reused corroded frames, which allows salt-driven moisture into the unit and fails the seal. This voids the manufacturer’s wind-load warranty. We correct it by removing the unit, reconditioning the rough opening to sound framing, and setting a new properly flashed window. Call (754) 238-2201 and we’ll send a technician who can tell you the real reason, not a guess.
We set marine-grade stainless fasteners, positive-drainage flashing, and a threshold pan that sends water away from the jamb, not into it. Elevated homes on Big Coppitt Key take wind and salt spray on every elevation, so the flashing detail has to be right the first time. A mainland shortcut here becomes a rotted sill within three seasons. We flash to Monroe County code, then register both warranty layers in writing before we leave.
It adds $400-$1,800 per affected opening, depending on what’s behind the wall. That covers new headers, king studs, fasteners, and sheathing corrections required to meet current uplift standards. We price it into the quote before we start, not after the wall is open, and anything unexpected gets priced and approved in writing before we touch it. Call (754) 238-2201 for a free estimate that accounts for this up front.
