AfterWindows & Doors Before & After in Three Lakes, FL
We’ve installed more than 18,000 windows and doors since 2012, and every job leaves a documented photo record. This gallery shows what that evidence looks like: out-of-plumb frames corrected, impact-rated glazing installed to Miami-Dade code, and sightlines measured twice so the quote and the finished opening match. No renderings. These are the actual conditions we found and the documented results we delivered.

Impact Window Replacement: Single-Hung to PGT WinGuard in a Three Lakes Ranch Home
The homeowner had a 1987 ranch near the Three Lakes Wildlife Management Area boundary with fogged glass in three bedrooms and a cracked sill nose on the master. We measured frame out-of-square at 3/8 inch on the worst opening, documented it in the survey the customer kept, and specified PGT WinGuard single-hung with a 0.30 U-factor and 0.23 SHGC (solar heat gain coefficient) for that east-facing wall. The written price before work started was $2,840 for three openings, including removal of the corroded aluminum, sill repair with pressure-treated blocking, and Miami-Dade notice of acceptance-compliant installation. After: documented sightline plumb, operable sash balance tested to 10,000 cycles, and a photo record showing the glazing tape bed and mechanical fastening pattern.
Sliding Glass Door Replacement: Corroded Rollers to CWS Tribute in a Three Lakes Patio Home
This was a patio home off Southwest 136th Street where the sliding panel had been “fixed” twice with new rollers that chewed through the bottom rail in six months. We found the threshold pan rotted through at the weep dam and the header deflected 1/2 inch under load. Our measured survey noted the structural condition, and the written scope included header reinforcement with a flitch plate, new pressure-treated sill pan, and CWS Tribute Series impact-rated sliding door with tandem stainless rollers rated for 350 pounds per panel. The customer kept the survey; we kept the photo record showing the pan flashing integration with the stucco drainage plane. Total: $4,650. The door rolls on one finger now. That’s Haven Clause 5: No surprises.
Custom Geometric Window: Trapezoid Transom Above Entry in Three Lakes
A homeowner near Three Lakes Park had a trapezoid transom above their front door that had leaked for three years. Previous attempts caulked the exterior; nobody checked the head flashing. We removed the interior drywall to trace the leak path, found the header unflashed and the rough opening rotted at the corners, and documented everything in the photo record the customer receives. The written scope specified a custom PGT aluminum trapezoid with 1-inch insulating glass, Low-E coating, and integral head flashing tied into the housewrap. We paired it with a Therma-Tru fiberglass entry door for a unified air seal. The trapezoid alone ran $1,890; the full entry system with door, sidelite, and transom was $6,200. The critical detail: the sightline measurement had to account for 2.3 degrees of rake in the existing header, which we corrected with a tapered substrate, not shims. That’s the difference between a quote and a measurement being the same document.
Energy-Efficient Window Replacement: ECO Window Systems in a Three Lakes CBS Home
Concrete block construction in Three Lakes holds heat. This homeowner’s FPL bill hit $340 in August with the thermostat at 78. We blower-door tested the house and found 34 percent of measured air leakage at the window perimeters, not the glass itself. The original vinyl windows had sagged in the Florida sun, breaking the argon seal and creating convection loops inside the insulated glass unit. Our survey specified ECO Window Systems impact-rated vinyl with a 0.28 U-factor, argon fill, and stainless steel warm-edge spacer to reduce thermal bridging at the glass edge. Twelve openings, including two picture windows with tempered glass for the pool enclosure sightline, totaled $8,900. The written price included removal and legal disposal of the old units, stucco repair with matching aggregate, and interior trim replacement where the old stools had been notched for blinds. We don’t guess at stucco texture; we sample it and document the match in the photo record.
Impact Garage Door Installation: Mr-Glass Model in a Three Lakes Wind-Borne Debris Zone
Three Lakes sits in a wind-borne debris region where garage doors are the largest breach point in most homes. This homeowner’s 16-by-7 non-rated door had no vertical reinforcement struts, a rusted bottom fixture, and a track system rated for 20 psf in a 50 psf zone. We specified a Mr-Glass impact-rated garage door with 14-gauge steel sections, reinforced track with 14-gauge jamb brackets, and wind load clips at each roller. The written scope included a new torsion spring assembly sized for the increased door weight, heavy-duty 13-ball nylon rollers, and a vinyl bottom seal with integrated fin. The door, hardware, and installation came to $3,750. Critical safety note: garage door spring assemblies store lethal tension. We do not recommend homeowner adjustment or removal. Our technicians are licensed and background-checked under Haven Clause 3, and the license number is provided before arrival. The photo record shows the spring tag, wind load sticker, and final balance test.
Multi-Slide Patio Door: ViewLux System for a Three Lakes Lake-View Home
A home on one of the Three Lakes chain had three separate French doors opening to the patio, each with a 6-inch step-down and a screen door that banged in the afternoon breeze. The homeowner wanted the wall gone, structurally and visually. We engineered a header upgrade with a concealed steel beam, specified ViewLux multi-slide impact-rated panels on a recessed stainless track with a flush sill, and integrated a retractable screen in the jamb pocket. The four-panel, two-track system spans 16 feet with each panel weighing 340 pounds, so we specified heavy-duty tandem trucks with stainless steel wheels and adjustable cap rollers. The written price of $14,500 included structural engineering for the header, permit pulling, inspection scheduling, and the documented photo record showing the beam connection, track level, and final sill integration with the paver deck. The sightline from the kitchen island is now uninterrupted to the water. That’s what we mean by specified by what the opening requires.
