In this valley, glass is where the money leaks out
A Las Vegas home doesn't lose money the way a Midwest home does. Here the enemy is solar heat gain — direct radiant sun pouring through under-specified glass for eleven hours a day, seven months a year, while your AC fights a load it can never win.
Most valley homes have either original single-pane aluminum windows or builder-grade dual-pane units whose seals failed years ago. Either way, the glass is doing almost nothing. You feel it as hot rooms on the west side of the house and a July bill you brace for.
Fix the glass and the doors and the whole system calms down. That's the entire business: the two openings that matter most, specified for the Mojave, installed right the first time.
Replacement windows built for the desert, not a catalog
We spec our own window line for Southern Nevada instead of ordering a national package. Triple-pane construction with two argon-filled chambers, Low-E coatings on three separate glass surfaces, and frames that won't bow when the wall behind them hits 150°.
- Triple-pane glass with dual argon-filled chambers
- Low-E coatings on three glass surfaces to reject desert heat
- Thermally broken, foam-filled frames that stop conduction
- Reinforced meeting rails engineered for 115° summers
- Triple-layer weatherstripping that seals out dust and air
- ENERGY STAR® Most Efficient criteria for the Southwest zone
Entry and patio doors that seal like they mean it
Stand next to your front door in July and you can usually feel the problem. Foam-core insulated fiberglass and reinforced steel doors, sealed on every edge, with locking hardware that makes the house feel solid when you close it.
- Polyurethane foam-filled cores for real insulation value
- Fiberglass and reinforced steel skins that won't warp or bow
- Multi-point locking hardware with reinforced strike plates
- Full-perimeter weather sealing plus adjustable thresholds
- Low-E decorative glass that adds light without adding heat
- Impact-rated glass options for wind-driven desert storms
Our installation standard
The best window in the world leaks if the install is sloppy. Every job — one window or thirty — follows the same sequence:
- 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 window replacement cost in Las Vegas?+
Most Las Vegas window replacement projects land between $650 and $1,200 per window installed, depending on size, frame type, and glass package. A typical 10-window single-story home runs roughly $7,500-$12,000. We give you a written, itemized price at the assessment — no vague ranges and no surprise change orders.
How much can new windows lower my power bill?+
Homeowners replacing single-pane or failed dual-pane windows in the Las Vegas Valley commonly see cooling costs drop 20-40%. The savings come from Low-E coatings rejecting solar heat gain, argon-filled chambers slowing conduction, and a proper air seal ending infiltration.
How long does installation take?+
Most whole-home window projects are installed in one day. Larger homes or jobs needing stucco or frame repair may take two. We give you an exact schedule window and show up in it.
Do your windows qualify for tax credits or rebates?+
Our ENERGY STAR® qualifying packages are commonly eligible for federal efficiency credits, and some NV Energy programs apply as well. We provide the manufacturer certification paperwork your tax preparer needs.
Do you replace the whole window or just the glass?+
Both. If the frame is sound and only the seal failed, glass-only replacement is often the smarter spend. If the frame is warped, leaking, or single-pane, full-frame replacement is the only fix that actually lowers your bill. We tell you which one you need.
What warranty comes with the windows?+
A double lifetime warranty: the manufacturer covers materials and glass seals, and we cover our installation labor for as long as you own the home. Not prorated, and it transfers on a documented sale.
Do you handle HOA approval?+
Yes. We prepare the architectural submittal packet with product specs, frame colors, and elevation notes so your HOA approval goes through without a second round.
