What makes a window actually energy efficient in Las Vegas
In the Mojave, efficiency is not about keeping heat in — it's about keeping radiant solar heat out. The number that matters most here is Solar Heat Gain Coefficient (SHGC), not just U-factor. A window marketed as "efficient" in Chicago can be the wrong glass entirely for a west-facing Las Vegas wall.
We spec our glass package for Southern Nevada: low SHGC coatings on multiple surfaces, insulating gas between panes, and frames that don't bow when the stucco behind them hits 150°. That's the difference between a window that looks new and a window that lowers your NV Energy bill.
Every unit we install is ENERGY STAR rated for the Southern climate zone and NFRC labeled, so you can read the performance numbers yourself before you sign anything.
Inside our energy-efficient window package
Standard on every window we install — not an upcharge tier:
- 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
Why an efficient window fails: the install
A perfectly specified window still leaks air and water if it's shimmed crooked or foamed sloppily. Our own crews handle every job — nothing subcontracted — following the same sequence on one window or thirty.
That's why we can back materials and labor with a double lifetime warranty that transfers to the next owner of your home.
- 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.
