Fast, Reliable Window Replacement Across North Key Largo
Window replacement in North Key Largo costs between $1,850 and $4,200 per opening for impact-rated units, with full-frame replacements of standard CBS home run $950-$2,100 per window. Most jobs inside Ocean Reef Club take 2-4 weeks from signed quote to final inspection, door swing and access scheduling included. We’ve worked the gate system on Ocean Reef Drive, through the property management office, and on the small streets off County Road 905. When a homeowner in North Key Largo calls TruePane at (448) 428-7290, the person picking up knows what a stem-wall elevation looks like, what the Monroe County wind load code says, and which manufacturer lines will pass the next audit. That’s the difference between us and a glazier working off a Miami map.
Why TruePane Windows & Doors Is North Key Largo’s Preferred Window Replacement Company
Dale Kessler founded TruePane in 2008 around one rule: if the pane is not true, the job is not done. But the work we do in North Key Largo sits on a stricter standard than most places. Monroe County enforces impact certification for every replacement opening. The Ocean Reef Club property management office requires contractor credentials before a crew rolls through the gate. We hold the credentials. We file the access applications before the first measure. We register both manufacturer warranty layers in writing before the truck leaves your driveway, and our Done Right Promise says if it is not done right, we make it right. No paperwork fights. No arguing. A square deal.
North Key Largo homeowners call TruePane because we show up on time, in uniform, with a live person answering the phone 24/7. Our team includes background-checked, trained installers who measure every opening twice and put Andersen, Pella, Marvin, PGT, CGI, and ES Windows quotes side by side on paper so you see exactly what you are paying for. In a community where a missed gate pass or a failed inspection sets a job back weeks, our process is built to clear access and pass code on the first try. We’ve done it enough times that the property management office knows our crew by name. We also offer a permanent 5% discount for seniors and veterans.
Our Window Replacement Services in North Key Largo
Impact-Rated Window Replacement
In North Key Largo, every replacement window must be certified to withstand 150+ mph wind loads. We install impact-laminated glazing from CGI, PGT, ES Windows, and ES Windows with frames built for the salt air off Card Sound and Biscayne Bay. A compliant quote includes marine-grade stainless fasteners, buck framing and anchoring specific to CBS construction, and the certification paperwork Monroe County requires at final inspection.

Full Frame Replacement
Full-frame replacement in North Key Largo means tearing out the old window down to rough opening and rebuilding it around an impact-rated, thermally broken frame. At a 1970s CBS house off Ocean Reef Drive, we found original single-pane aluminum double-hungs with corroded sashes, failed EPDM seals, and fogged insulated glass units from seal failure. Our crew removed the non-impact frames, installed fusion-welded impact-rated glazing with flashing tape, and scheduled the final inspection through the club’s gate access while the owners were back for season. Expect the same when we open your walls: old anchors out, new stainless in, new flashing, square jambs, and a window that slides true.

Insert Window Replacement
Insert replacement keeps the existing frame and drops a new impact-rated sash and glass into the opening. On homes with sound frames but dead seals or seized hardware, this is the most cost-effective path to a compliant window. In North Key Largo, we size inserts to the original opening and re-anchor the jamb with stainless fasteners because standard zinc-coated screws corrode in Card Sound air within two or three years.

Storm Window Replacement
Older storm windows on seasonal Ocean Reef Club homes often fail during the August-September stretch when owners are away. We inspect the primary window, check the storm unit for pitting and seal loss, and replace both as a matched pair when the primary window is non-compliant. If your storm window is torn from its track or cracked from wind-driven debris, call (448) 428-7290. We’ll schedule the access pass and get the opening sealed and certified.

Energy-Efficient Upgrade
North Key Largo’s shoreline exposure drives cooling loads year-round. Upgrading from a 1970s single-pane aluminum unit to a double-glazed, low-E, argon-filled impact window drops solar heat gain and cuts the load on the AC. We quote specific U-factor and SHGC numbers from CGI, ES Windows, and PGT so you see the performance on paper before you spend a dollar.

Trusted Brands We Service in North Key Largo
TruePane is an authorized installer for more than a dozen manufacturer lines, and we stock and service CGI, ES Windows, and PGT for North Key Largo customers specifically. We understand these products at the frame level. We know CGI’s impact certification paperwork. We know ES Windows’ stainless hardware. We know PGT’s anchoring requirements. That means repairs and replacements move faster because we aren’t ordering from a warehouse in Fort Lauderdale and waiting for a truck. Whether you need warranty work, hardware replacement, or a full window replacement, we quote the manufacturer line best suited to your elevation, your exposure, and your HOA and club requirements, not whatever we have on the shelf.
Common Window Replacement Problems We See in North Key Largo Homes
- Salt-air corrosion on standard aluminum frames. Homes on the west side near Card Sound and channels off Biscayne Bay eat through basic aluminum frames in two to three years. We replace with anodized or PVC-clad frames and marine-grade stainless hardware.
- Failed EPDM seals and fogged glass on original builder windows. The 1970s and 1980s homes inside Ocean Reef Club still carry single-pane units with seals gone brittle from UV and salt, leaving fogged IGU units that no longer insulate or meet code.
- Non-impact-rated windows that will fail a Monroe County inspection. Anyone who swaps in standard glass here is signing a stop-work order and a second bill. Compliance starts with the product and ends with the paperwork.
- Denied gate access for uncredentialed contractors. A cheap bidder without Ocean Reef Club credentials will get turned away at the gate, and the homeowner pays for the missed day. We file access applications before the crew arrives.

FAQs - Window Replacement in North Key Largo
Yes. Every contractor working inside Ocean Reef Club must hold pre-approved credentials through the property management office, and the access application has to be filed before the crew arrives at the gate. We hold the credentials and file the paperwork as step zero on every quote. Call (448) 428-7290 with your property address and we’ll confirm access before you commit.
Monroe County requires replacement windows to be certified to 150+ mph wind loads, typically Miami-Dade or Florida Building Code impact-rated, with product approval documentation that matches the opening. A compliant quote includes that certification paperwork. A cheap quote often leaves it out, and the next insurance audit or resale inspection catches it. We quote the rating, the product approval, and the installation method line by line.
North Key Largo sits between Card Sound and Biscayne Bay on the west and the Atlantic on the east, so the air is nearly always salt-laden, and standard aluminum frames and zinc-coated hardware break down within two or three years. We use anodized or PVC-clad frames and marine-grade stainless fasteners, and we flash every opening to keep the anchorage dry.
Call (448) 428-7290 as soon as you’re able. We’ll come out, assess the opening, identify whether the unit was impact-rated and whether the damage is a seal failure, frame failure, or glazing failure, and give you a line-item replacement quote. If the window was non-compliant before the storm, we’ll explain what a code-compliant replacement includes and what the permit path looks like.
Yes. A documented impact-rated window replacement that meets Monroe County’s 150+ mph standard can reduce your windstorm premium or qualify you for a mitigation credit, but only if the paperwork is complete and registered with the manufacturer. We register both warranty layers in writing and provide the documentation your insurer needs.
