Sliding glass door replacement for the hottest room in the house.
Your patio slider is the largest single pane of glass you own. We replace it with a Low-E insulated unit on stainless rollers that glides with one finger and stops the afternoon heat at the glass.

Why one door can drive your whole cooling bill
A standard two-panel slider is roughly 40 square feet of glass. A three-panel is closer to 60. In most valley homes it faces the backyard, which means direct sun from early afternoon until sunset — the exact hours your AC is already struggling.
If that glass is single-pane, or a dual-pane unit whose seal failed and let the argon out, it's the single biggest thermal hole in your envelope. That's why the family room runs five degrees warmer than the thermostat says.
Replacing it is the fastest measurable comfort change we can make in a Las Vegas home — usually in a single afternoon.
What's in our patio doors
Every slider we install is specified for Southwest solar load and long-term smooth operation:
- Low-E insulated glass engineered for Southwest solar heat gain
- Stainless steel tandem roller assemblies rated for heavy panels
- Thermally broken frames that don't conduct heat into the room
- Reinforced interlock with anti-lift blocking
- Keyed multi-point latching hardware
- Optional laminated security glass and retractable screens
Configurations we install
Two-panel slider
The standard replacement for most valley patios. One fixed panel, one operating panel, clean retrofit into the existing opening.
Three-panel slider
Wider openings with a center operating panel or two operating panels — more glass, more light, same thermal control.
French sliding doors
The look of hinged French doors with slider mechanics and sealing — no swing clearance needed inside.
Multi-slide / pocket systems
Panels that stack or disappear into the wall to open the room to the patio. Requires header and framing evaluation.
Repair, glass-only, or full replacement
We quote the smallest fix that actually solves your problem. Sticking panel with good glass? That's a roller and track service call. Fogged glass in a sound frame? Glass-only insert replacement.
Full replacement is for out-of-square frames, water damage at the sill, single-pane units, or anything where the frame itself is the thermal problem.
- Laser-measured openings, custom-built to the quarter inch
- Full frame inspection with stucco and framing repair if needed
- Perimeter foam insulation and code-compliant flashing
- Interior and exterior trim finished the same day
- Post-install operation, lock, and air-seal verification
- Complete cleanup and old-unit haul-away included
Frequently asked questions
How much does a sliding glass door cost in Las Vegas?+
A two-panel sliding patio door typically runs $2,200-$4,200 installed, and a three-panel unit $3,600-$5,500 installed. Price moves with glass package, frame material, and whether the opening needs structural repair.
Can my sticking slider be repaired instead of replaced?+
Often yes. Worn rollers, a dirty or slightly bent track, and misadjusted interlocks are all repairable. Replacement is the right call when the frame is out of square, the glass seal has fogged, or the unit is single-pane.
Why is the room with my patio door always the hottest?+
Because a patio slider is usually 40+ square feet of glass facing the yard — often west or south. With a clear or failed dual-pane package, that single opening can admit more solar heat than every window in the room combined.
How long does a sliding door replacement take?+
Most patio slider replacements take 4-6 hours with one crew. Multi-panel or structurally modified openings can run a full day.
Do you install multi-slide or pocket doors?+
Yes. Multi-slide and pocketing systems that open a wall to the patio are available, and they require framing and header evaluation. We assess load-bearing conditions before quoting.
Are sliding doors secure?+
Modern units are far more secure than the 1990s sliders they replace: reinforced interlocks, anti-lift blocks, and keyed multi-point latching. Laminated glass options add forced-entry resistance.
