Why TruePane Windows & Doors Is Tavernier’s Preferred Custom Windows & Doors Company
TruePane Windows & Doors was founded in 2008 by second-generation glazier Dale Kessler on a rule that still hangs in the shop: if the pane is not true, the job is not done. We’re an authorized installer for more than a dozen manufacturer lines including PGT, CGI, and Simonton. But what matters in Tavernier isn’t the catalog. It’s knowing that Monroe County’s permit desk will reject a window spec that passes on the mainland, and knowing how to prevent that stall before it starts.
Our technicians are background-checked, uniformed, and measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves the driveway under The Keystone Standard. Dispatch is coordinated from our South Florida office in Miami, and our crews serve Tavernier locally. When a Tavernier homeowner calls, they get a company that plans to be in town in thirty years, not a regional call center.
Our Custom Windows & Doors Services in Tavernier
Every custom job in Tavernier starts with a conversation about Custom Windows & Doors done right, then moves to inspection and written allowances. Here’s what we handle most often.
Custom Shape Windows
Round tops, trapezoids, octagons, and radius corners are common in Tavernier’s older concrete block homes, and none of them come off a shelf. We order direct from manufacturers like PGT and CGI with full Miami-Dade NOA documentation submitted to Monroe County before the permit application. We also spec marine-grade stainless hardware, because standard window hardware on this island starts showing rust bloom within a few years on both the Atlantic and Florida Bay sides.

Commercial Storefront Glazing
Tavernier’s retail and office storefronts sit directly in the High-Velocity Hurricane Zone, so replacement glazing must carry impact approval or the building owner is carrying code liability along with wind exposure. We handle storefront glass, framing, and hardware replacement to HVHZ standards, working around business hours along the Overseas Highway corridor.

Curtain Wall Systems
Larger commercial and multifamily buildings in Tavernier with curtain wall assemblies face the same bidirectional salt problem as houses, just at scale. We replace failed glass units, corroded mullion caps, and deteriorated sealant joints with materials rated for full marine exposure, and we coordinate directly with the Monroe County permit desk on NOA submittals so the job doesn’t stall at inspection.

Architectural Grilles & SDLs
Simulated divided lites and true architectural grilles are one of the most popular upgrades for Tavernier homeowners replacing jalousies with impact-rated casements or picture windows. We order grilles and SDLs from the manufacturer matched to the frame finish, so the whole assembly carries one NOA and one written warranty. No aftermarket kits, no field-built compromises.

Oversized Glass Panels
Homes with elevated decks and wide ocean or bay views often call for oversized fixed panels, and those panels are the heaviest wind load in the entire window schedule. We reinforce headers and sills to HVHZ uplift requirements, specify the correct glass make-up for the exposure, and have the NOA documentation on file with the county before permit submittal.

Trusted Brands We Service in Tavernier
We’re an authorized installer for lines homeowners in Tavernier ask for by name, including PGT, CGI, and Ply Gem. We quote side by side on paper so you see exactly what you’re buying, and we register both warranty layers in writing before the truck leaves the driveway. Sourcing from these manufacturers also means our lead times for custom openings in Tavernier stay predictable, even at the height of hurricane season when glass supply tightens.
Common Custom Windows & Doors Problems We See in Tavernier Homes
- Hidden aluminum frame corrosion. Tavernier sits on a narrow limestone strip between the Atlantic and Florida Bay, so every structure gets salt spray from two directions. We regularly find aluminum slider frames that look fine from the inside but are losing structural integrity inside the rough opening, where the salt has been working for decades.
- Undersized or rotted wood framing around original jalousie openings. Homes built in the 1950s through early 1970s often have jalousie rough openings with framing that was never sized for a modern impact-rated unit. The jamb and header must be reinforced to meet HVHZ uplift loads, and that work is code-triggered once the opening is exposed.
- Failed sealant and flashing behind old window flanges. The bidirectional salt air oxidizes standard sealants faster here than anywhere on the mainland coast. We’ve opened walls in Tavernier and found flashing tape fully detached, with water tracking into the wall cavity and nobody seeing it from inside until the drywall stained.
- Permit stalls from incomplete NOA documentation. Monroe County’s permit desk requires manufacturers’ full NOA documentation before a permit is issued for any window or door replacement. Mainland crews who are unfamiliar with Keys inspections regularly have jobs delayed when they submit only the product name and get rejected. We verify the NOA before the permit goes in.

FAQs - Custom Windows & Doors in Tavernier
A Miami-Dade Notice of Acceptance (NOA) and a Florida Product Approval are both accepted for impact-rated window and door products in Tavernier under Monroe County’s HVHZ requirements. The permit desk requires the full product approval documentation, not just a product name or model number, before the permit is issued. If you’re replacing a custom window, your contractor should verify the exact NOA or Florida Product Approval for the unit being ordered and include that documentation with the permit submittal. Manufacturers like PGT, CGI, and Simonton publish these documents, and we pull the correct one before we ever file. Call (813) 320-9346 and we’ll check your proposed product’s approval status as part of the free estimate.
We carry a written structural allowance in every Tavernier contract, typically $3,000 to $6,000 depending on the size of the job, so the band-aid fix isn’t the only option on the table when we find rotted jamb anchors or corroded buck framing. When the rough opening is exposed, we address what we find in the order the county inspector will require: replace the damaged framing, install marine-grade stainless anchors, reflash with salt-rated sealant, and document everything in writing for the permit. The homeowner approves any allowance use before we touch the opening. Call (813) 320-9346 to schedule a free estimate and we’ll explain exactly how our allowance language protects you.
If the aluminum frame itself is corroding from the salt air, reglazing won’t fix it and the county may require a fully approved replacement unit. You can replace just the glass only when the existing frame is structurally sound and it meets the HVHZ impact requirements for your opening. In many pre-1992 Tavernier homes with original sliders, the frames are too far gone to pass inspection once opened up. We’ll pull the unit and show you the condition before we quote anything. Call (813) 320-9346 for a free estimate.
We use high-performance sealants rated for full salt immersion exposure and marine-grade flashing products on every custom window and door in Tavernier. Standard construction sealant degrades quickly here on the narrow limestone strip between the Atlantic and Florida Bay. Flashing tape also oxidizes and separates, which is exactly what we’ve found behind old jalousie openings in Harborview and other Tavernier neighborhoods. We spec marine-grade products as the standard, not an upgrade, because the island’s bidirectional salt spray demands it. Call (813) 320-9346 for exact product specifications on your job.
Custom impact-rated windows for non-standard Tavernier openings typically take 4 to 8 weeks from order to delivery, depending on the manufacturer and the time of year. The permit does affect the timeline because Monroe County requires full NOA documentation before the permit is issued, and that review can add anywhere from a few days to two weeks depending on the county’s workload. We lock down the NOA paperwork and file the permit the same week the deposit clears, so the manufacturing lead time and permit review run in parallel. Call (813) 320-9346 and we’ll give you a realistic schedule for your specific opening.
Why the NOA Paperwork Matters Before Demo, Not After
In Tavernier, every custom window or door replacement must carry a Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval for impact resistance, and Monroe County’s permit desk requires the full NOA documentation before a permit is issued. It’s not enough to tell the county you’re installing an impact-rated PGT or CGI unit. You have to produce the exact approval document for the exact product. This means hidden framing or waterproofing issues discovered after demo cannot be fixed ad hoc without triggering a permit revision. Mainland crews unfamiliar with Keys inspections regularly have jobs stalled when inspectors reject window specs that would pass on the mainland. Pre-permit NOA verification plus written allowances is the only way to prevent stalled inspections and keep the schedule moving.
We’ve seen it firsthand. When we opened up a 1968 concrete block home in Tavernier’s Harborview neighborhood to replace original jalousie windows with custom impact-rated casement units, our crew found badly corroded jamb anchors and failed flashing tape from decades of bidirectional salt spray. We had already written a $4,000 structural allowance into the contract, so the owner approved a new pressure-treated buck and marine-grade stainless anchors the same day, keeping the Monroe County HVHZ inspection on schedule. That’s the difference between a crew that knows Tavernier and a crew that’s just passing through.
Dale Kessler still keeps the whiteboard rule in the shop: if the pane is not true, the job is not done. That’s how we build every custom window and door order from the Manufacturers’ catalogs to the county inspection. Call (813) 320-9346 and we’ll walk through your specific openings, your product options, and the NOA paperwork before you spend a dime.
