ES Windows Windows & Doors in Key Largo, FL | TruePane Windows & Doors
TruePane Windows & Doors provides independent ES Windows service across Key Largo, from Window Installation - Key Largo for older 600 Series frames to full replacement with 800 and 900 Series impact units. What makes our ES Windows work different here isn’t a dealership plaque. It’s that we’ve spent years watching how salt air from both the Atlantic and Florida Bay sides attacks aluminum frames, hardware, and seals, and we build every repair or replacement around that double-front exposure. Call (448) 428-7290 and you’ll talk to a live person who can discuss your specific opening, not a call center.
Why Key Largo Residents Choose Us for ES Windows Service
We work on ES Windows every week in Key Largo, from Door Installation - Key Largo at older concrete block cottages on the bayside streets to the elevated canal-front homes built after Hurricane Andrew. Dale Kessler, our owner, grew up in Naranja and learned glass and framing in Miami Dade College’s building construction program before putting in years on residential and commercial work across Miami-Dade and Monroe counties. He’s the reason we treat an ES 700 Series slider with a corroded track as a diagnosis problem first and a parts order second. That’s also why we keep OEM balances, pivot bars, and glazing wedges on hand, and why we’ll tell you plainly when a salt-eaten frame isn’t worth patching. If the pane is not true, the job is not done.
Common ES Windows Windows & Doors Problems We Solve in Key Largo
- Salt-driven frame oxidation on ocean-side elevations. ES 700 Series frames on the Atlantic-facing side of Key Largo show white powder corrosion at sill corners and weep holes within 8 to 12 years. The problem isn’t just cosmetic. Once the weep system clogs with aluminum oxide, water backs up into the track and starts attacking the balance shoes and pivot hardware.
- Glazing gasket shrinkage and seal failure on impact casements. ES 800 and 900 Series casement windows can still leak wind-driven rain at the upper sash joint during a 130 mph gust even when the glass itself passes pressure testing. We’ve seen this on several Key Largo canal-front homes where the gasket hardened from constant UV and salt exposure. The fix is replacing the gasket with a marine-grade profile and then testing the assembly, not caulking over the outside and hoping.
- Roller bearing and track corrosion on sliding doors. Canal-front homes put stainless steel track and rollers under a constant salt film. Panels start grinding within a few seasons. The catch is that often the track itself has pitted where the rollers rest, so dropping in new rollers buys maybe another year before the same wear pattern returns. We check the track profile before we sell you parts.
- Fused frame-to-masonry bond on original ES 600 Series windows. In the 1950s through 70s concrete block cottages around Key Largo, original aluminum frames have sometimes chemically locked into the stucco. Extraction means core drilling and custom pressure-treated bucks, not a pry bar and a hammer. We bring the big drill and the patience, because breaking the block is a much bigger repair than the window.
- Impact glass that passes testing but leaks around the frame perimeter. A unit’s glass can hold at 170 mph while the perimeter seal fails, allowing water into the wall cavity. This is especially common where the original frame was set decades ago and the sealant has turned brittle in the salt air. On Key Largo, that’s a permit condition waiting to fail, so we treat perimeter sealing as part of the job, not an add-on.
ES Windows Service in Key Largo: What Local Conditions Mean for Your Equipment
Key Largo’s official wind design speed for most of the island is 170 mph under ASCE 7-22 for Risk Category II structures. But here’s the part most mainland window companies don’t know: some exposed canal-front homes are being pushed to 180 mph by Monroe County reviewers as permit conditions get updated. That means an ES Windows impact unit that carried a Miami-Dade notice of acceptance may still need additional anchoring or perimeter seal upgrades to satisfy a Key Largo-specific permit condition. We’ve been through this with homeowners east of the highway around Tarpon Basin and in the older canal subdivisions. The glass unit itself is rarely the sticking point. Usually it’s the anchoring schedule and the sealant spec at the buck. This is exactly why a generic South Florida impact window quote doesn’t transfer one-to-one onto this island, and why we pull the Monroe County permit and review the wind load map before we order anything. If it’s not in writing, it’s not a promise, it’s a sales pitch.
One more thing worth stating plainly: Key Largo sits on a strip roughly two miles wide at most, with the Atlantic on one side and Florida Bay on the other. There is no inland buffer. Salt-laden humidity driven by the southeast trades and gulf breezes hits the same ES Windows frame from two directions. We regularly see an ES 700 Series window where the ocean-side face is heavily oxidized while the bay side is only lightly pitted. That’s the kind of local detail you only learn by installing and repairing on the island itself, and it changes which frame treatments and replacements we recommend.
ES Windows Models & Products We Service in Key Largo
We work on the full ES Windows range found across Key Largo: the older 600 Series non-impact single-hung and casement, the mid-range 700 Series aluminum line, the 800 Series impact casement and fixed windows, and the 900 Series heavy-duty impact and commercial-grade frames common on post-Andrew elevated homes. For balances, pivot bars, and glazing wedges, we use genuine ES Windows parts where the original component is still listed. For frames and sills chemically compromised by salt, we source marine-grade aftermarket aluminum and hardware that meets Monroe County impact standards. And when a frame is heavily oxidized or a glass pack has de-laminated, we’ll tell you straight: on this island, full-frame replacement is often cheaper long-term than another round of patch repairs. We also do full frame replacement, wind mitigation inspections, and code compliance work alongside ES Windows sales & service calls.
ES Windows Service Pricing in Key Largo
Most ES Windows repairs in Key Largo fall between $120 and $300 for roller swaps, balance resets, or gasket replacement, while full-frame extractions from older CBS walls run higher because of the demolition and buck work involved. That’s the honest spread, and the exact number depends on what we find when we open the frame. Both manufacturer warranty layers get registered in writing with The Keystone Standard, and our Done Right Promise covers every repair and install we do. You get a written line-item quote before work begins, never after. Call (448) 428-7290 and we’ll send a uniformed, background-checked technician to measure your openings and give you a real number.

That depends on the frame and the glazing channel. If the frame is structurally sound and the glazing wedge or gasket is still intact, we can often change just the glass pack. If the frame shows salt corrosion at the corners or the channel has pitted, a full-frame replacement is usually the better call because a new glass pack in a compromised frame won’t hold its rating. Call (448) 428-7290 and we’ll assess the whole opening, not just the broken pane.
Your track is feeding on the rollers. Salt film from the canal air pits the stainless steel, and once the track surface roughens, it chews through new rollers faster each time. The long-term fix is replacing the track with a marine-grade profile and matching rollers, not just installing a third set of wheels. We see this constantly on finger-canal homes throughout the island.
The extraction work itself usually adds a few hundred dollars to the replacement job, depending on how many openings and how deeply the frame has bonded to the block. It’s not a flat rate, because some frames come out with hand tools and some need core drilling and a pressure-treated buck from jamb to jamb. We’ll give you a written quote after we see the opening, and it includes the demolition, buck, install, and permit work. Estimates are free.
Most ES Windows 800 and 900 Series impact units meet Miami-Dade’s notice of acceptance, which is a solid baseline. But Key Largo’s Monroe County review and its 170 mph design speed, and in some cases a push toward 180 mph, mean the anchoring schedule and perimeter sealant spec may need upgrading for this island. We’ve had to add anchors and reseal perimeters on units that would have passed inspection on the mainland. Call (448) 428-7290 if you’re mid-permit.
You can restore the look, but not the rating. Jalousie frames have no impact resistance and their corrosion, especially on a Key Largo cottage that’s been in the salt for sixty years, means even restored frames won’t give you a wind mitigation credit. Many of our customers choose to replace them with a modern impact unit in a similar line, like an ES 800 Series casement. That’s a conversation we’ll have with you straight, not after the first estimate.
