PGT Windows & Doors in Marathon, FL | TruePane Windows & Doors
TruePane Windows & Doors is an independent PGT service provider serving Marathon, FL, and offers the same expertise as our Coral Gables Pgt service. We install, repair, and replace PGT impact windows and doors across the island, and here’s the thing that matters most: Marathon sits in Florida’s High-Velocity Hurricane Zone, which means every PGT unit we touch has to meet Miami-Dade NOA standards or it doesn’t belong on your house. We’re not factory-authorized, but we know these products cold because we’ve been servicing them in the Keys’ salt-heavy conditions for years. Call (813) 320-9346 and a live person answers.
Why Marathon Residents Choose Us for PGT Service
Dale Kessler grew up in Seminole Heights and has spent the better part of two decades measuring, setting, and sealing windows and doors. That matters in Marathon because this island punishes lazy work faster than anywhere else we operate. Salt air, trade winds, and hurricane cycling expose every shortcut within eighteen months. Our crew treats PGT service as a craft commitment, not a transaction. We order OEM PGT glass and frames for impact-rated replacements because HVHZ approval demands an exact product-series match. For non-structural hardware like rollers and locks, we use marine-grade aftermarket parts that hold up better than factory standard in this environment. We are a local company plans to be in town in thirty years, and we stand behind the work with a 90-Day Done Right Promise and The Keystone Standard: both warranty layers registered in writing before the truck leaves your driveway. No arguing, no fine print that covers neither.
Common PGT Windows & Doors Problems We Solve in Marathon
PGT builds solid impact products, but Marathon’s conditions stress them in ways a mainland contractor never sees. Here are the failures we address most often:
- White oxidation and pitting on WinGuard aluminum corners. Salt-laden air attacks machined aluminum frames, starting at the sill horns on canal-side elevations. We see pitting so deep in older frames that the corner join loses structural integrity. The fix is cleaning, sealing, and replacing corroded components before the frame needs a full tear-out.
- Weep holes clogged with salt crystals and calcite. Evaporating bay water leaves mineral deposits in sliding door bottom tracks, which blocks drainage. The track floods, water sits against the frame, and hidden corrosion spreads. We clear the weep system and upgrade covers on canal-front homes where the standard PGT design simply can’t keep up.
- Foam-injected mullion compression on pre-2010 PGT units. Hurricane-cycling pressure compresses old foam mullions, leaving a subtle seam leak during prolonged southeast winds. We spot this during routine service before visible damage shows.
- Seized stainless steel rollers on older PGT sliding doors. Fine salt grit embeds in the bearing cages. The door gets heavy, operation gets harder, and eventually stress cracks appear at the roller housing. We replace with marine-grade rollers that outlast the original equipment.
- Fogged impact glass on canal and bay frontages. Constant pressure and moisture cycling flexes seals until the argon escapes. Once fog forms, the glass needs replacement, not cleaning. We match the exact PGT product series to keep your NOA certification valid.
PGT Service in Marathon: What Local Conditions Mean for Your Equipment
Here’s what most contractors miss about Marathon: the island is roughly a mile wide at its widest, with the Atlantic on one side and Florida Bay on the other. That means every single PGT window on your home faces salt exposure from at least one water direction, and canal-front homes get it from below as well. There is no inland buffer, no protected elevation. A window on the “calm side” of a house in North Carolina is protected by the structure. In Marathon, that same window gets the same salt load as the ocean-facing one because the bay side is just as aggressive. Off Sombrero Beach Road we replaced six original jalousie windows with PGT WinGuard 550 series impact single-hungs. The old aluminum frames had salt-welded to the CBS openings. We chiseled out the corroded remnants, installed full-perimeter vinyl buck flashing, and anchored with marine-grade Titen HD screws before setting the new PGT units. That homeowner’s wind mitigation report went from non-compliant to a 180 mph rating, and the windstorm premium dropped by 38%. If it needs to be in writing to be true, we will put it in writing.
PGT Models & Products We Service in Marathon
Our PGT service work covers the full line of impact-rated products, including Pgt service in Key West and Marathon: WinGuard Aluminum and Vinyl impact windows, the 770 Series impact casement and awning windows, 1200 and 1400 Series sliding glass doors, and SpectraGuard single-hung impact windows. We always order OEM PGT glass and frames for impact replacements because the Miami-Dade NOA approval depends on exact product-series matching. For non-structural components, we stock marine-grade aftermarket rollers, locks, and weatherstripping that outperform PGT’s standard salt-susceptible equivalents. That means faster turnaround for Marathon homeowners and parts that actually last in this environment. We handle hurricane impact windows, wind mitigation and code compliance, and insert window replacement across Marathon.
PGT Service Pricing in Marathon
PGT window and door service in Marathon typically runs from $145 for a single window tune-up to $900-$1,800 for a full sliding glass door roller and track rebuild, depending on corrosion damage and parts needed. Cracked impact glass replacement starts around $275 per pane for smaller geometric fixed units and runs higher for large casement or awning sashes. Several factors drive cost here: salt corrosion on frames, the need for marine-grade hardware upgrades, and HVHZ code compliance verification. Every free estimate includes a full inspection, a written line-item quote, and no surprise charges. Call (813) 320-9346 to schedule yours. We also honor a permanent 5% discount for seniors and veterans.

FAQs - PGT Windows & Doors in Marathon
No. Monroe County code requires every replacement window and door in Marathon to carry a Miami-Dade Notice of Acceptance (NOA) or equivalent HVHZ approval. Standard windows are not a legal option here. If a contractor offers to install non-impact PGT windows in Marathon, walk away. Call (813) 320-9346 and we’ll confirm your current units meet code.
It can usually be serviced. The problem is almost always salt grit embedded in the roller bearings and mineral buildup in the track, not a failed frame. We replace the rollers with marine-grade stainless units, deep-clean the track and weep system, and the door slides like new. If corrosion has spread into the frame itself, we’ll tell you straight and quote replacement. Call for an exact assessment.
For most canal-front exposure, no. PGT’s standard weep covers are designed for typical coastal conditions, but Marathon’s salt-spray from below means canal-front doors and windows evap-concentrate minerals at a rate those covers cannot handle. We upgrade to marine-grade covers and schedule them for seasonal cleaning. It’s a small cost that prevents hidden frame corrosion. Call (813) 320-9346 and we’ll take a look.
When you replace non-impact windows with PGT impact-rated units that carry valid HVHZ approval, your wind mitigation inspection can show the entire opening as protected, which qualifies for significant windstorm premium reductions. The key is that the PGT product series on the NOA must match what’s installed. We handle the paperwork, pull permits, and make sure the inspection passes, just as we do for our Pgt in Homestead customers. Call for a free estimate.
Yes, as long as the frame is structurally sound and the replacement glass matches the exact PGT product series on the original NOA. We order OEM PGT glass for this reason. If the frame is corroded or the product series is discontinued, full replacement becomes the only legal option. We’ll show you both quotes side by side so you can decide. Call (813) 320-9346.
