New Construction & Replacement
Residential Windows
Full-frame new construction or clean pocket replacement — energy-rated glass, precise reveals, and finish carpentry that leaves the room looking better than before we arrived.
Residential & Commercial Glass
Windows, glass, and storefronts built to hold the line.
Highline Glass Group installs residential windows and fabricates custom shower enclosures, commercial glass paneling, partitions, and storefront systems across Winter Park and Central Florida — precision glazing with a finish that reads premium from the street or the living room.
What We Do
Five glass disciplines, one standard of finish.
Frameless, Semi-Frameless & Framed
Shower Enclosures & Glass Bath
Custom-measured frameless and semi-frameless enclosures, glass tub doors, and bath panels in clear, low-iron, or textured glass with a hardware finish to match your fixtures.
Curtain Wall & Feature Glazing
Commercial Glass Paneling
Curtain wall, spandrel, and feature glass paneling for lobbies, facades, and interior build-outs — engineered for load, wind, and code compliance on every elevation.
Office, Retail & Workplace Interiors
Glass Partitions & Separations
Demountable and fixed glass partition systems that divide space without closing it off — acoustic-rated options available for private offices and meeting rooms.
Entry Glazing & Retail Facades
Storefront Systems
Aluminum-framed storefront and entry systems built for daily traffic — narrow sightlines, durable hardware, and glazing options tuned for street-level visibility.
Our Work
See the difference in the opening.
Real jobs, start to finish. HGG measures, fabricates the surround, and installs — window and door units come from manufacturer partners we trust, like EcoGlass in Longwood, FL.
Residential Windows
Warped frames, foggy insulated glass, and drafts swapped for a clean, energy-rated unit set flush and square — with trim and paint lines restored to match.
- Lower energy bills from properly sealed, Low-E glass
- Quieter interiors with laminated or double-pane options
- Renewed curb appeal without changing the opening
Multi-Slide Patio Doors
A tired sliding door and its rotted framing removed down to the rough opening, replaced with a four-panel folding glass wall that opens the living room straight onto the pool deck.
- Full-width sightlines, panels stack clear of the opening
- New framing and flashing, not just a drop-in unit
- Screens and hardware sized for daily indoor – outdoor use
French Doors & Patio Windows
Original wood French doors — swollen, hard to latch, and past re-painting — replaced with a matching door-and-window set built for Florida humidity.
- Doors that latch true in every season
- Flanking windows added for more patio light
- Trim and paint lines matched to the house
Commercial Glass Paneling
A full run of angled, trapezoid-shaped commercial windows set into a pre-engineered metal building — each opening fabricated to its own angle, not a standard rectangle.
- Custom angles measured and cut per opening
- Weathertight seal against metal panel siding
- Consistent black-frame line across the whole elevation
Storefront Applications
Full-height storefront glazing and glass entry doors set into a commercial retail unit — narrow black sightlines, daylight to the back wall, and hardware built for daily foot traffic. We don’t have a “before” photo of this specific bay yet — check back as we document more storefront jobs start to finish.
- Daylight reaching deep into the retail space
- Slim aluminum framing for maximum glass area
- Commercial-grade entry door hardware

We walk the space with you, take precise field measurements, and talk through material, performance, and budget so there are no surprises later.

You choose glass type, framing finish, and hardware from options suited to your project — we handle the specification and code details.

Every install is backed in writing, separate from manufacturer glass and hardware warranties.

FAQ
Questions we hear before the first visit.
What areas do you serve?
We're based in Winter Park, FL and serve Central Florida — Orlando, Maitland, Altamonte Springs, Longwood, Casselberry, and the surrounding area. Not sure if you're in range? Just ask.
Do you manufacture your own windows?
No — HGG is a specialty glass installer, not a manufacturer. We source window and door units from trusted local manufacturers, including EcoGlass in Longwood, FL, and handle measuring, fabricating the surround, and installing to spec.
How long does a typical window or door replacement take?
Most residential replacement jobs (a handful of openings) are completed in one to three days. Full-house window packages, multi-slide door installs, or commercial storefront glazing take longer — we'll give you a firm timeline at your on-site consultation.
Do you offer free estimates?
Yes. Every project starts with a free, no-obligation on-site consultation and estimate — submit the form below or call us directly.
What's the difference between full-frame and pocket replacement?
Full-frame replacement removes the entire old frame down to the rough opening — used for new construction or when a frame is damaged. Pocket (insert) replacement fits a new unit inside the existing frame, which is faster and less invasive when that frame is still sound.
Do you work on commercial and storefront projects, or just homes?
Both. Alongside residential windows and glass showers, we install commercial glass paneling, glass partitions for offices and retail, and full storefront systems for retail and commercial buildings.
What warranty do you offer?
Every installation is backed by a written HGG workmanship warranty, separate from the manufacturer's glass and hardware warranty on the unit itself. We'll give you both in writing before work begins.
