The Las Vegas window company homeowners actually keep the number for.
Beyond Energy is a veteran-owned, licensed window contractor in Las Vegas. We spec our own desert-rated window line, install it with our own crews, pull the permits, and warranty both the product and the labor for life.
Talk to a local window contractor
Takes 30 seconds. A real person calls you back — usually within the hour.
What separates a window company from a sales operation
Most of the window companies advertising in Las Vegas are marketing organizations. They sell the appointment, mark up a national product line, then hand your house to whichever subcontracted crew is available that week. You feel the difference two summers later, when the seal fails and nobody owns it.
We built the opposite. One window line specified for the Mojave, one crew of employees, one phone number, and a warranty that covers the glass and the installation. When something needs attention, the company that sold it is the company that shows up.
That is the entire pitch for choosing a local window contractor over a national brand: accountability that survives the sale.
Credentials to check before you sign with any window contractor
Ask us these, then ask the next company. The answers tell you everything.
- Nevada state contractor license, bonded and insured — ask for the number, not a logo
- Employee installers, not subcontracted crews rotating between companies
- Permits pulled by the contractor and Clark County inspections scheduled for you
- Published NFRC ratings — U-factor and solar heat gain coefficient — on the exact glass being quoted
- A written labor warranty, not just a manufacturer product warranty
- Line-item pricing per opening, so you can see what each window actually costs
In-house crews, desert-specified glass
Triple-pane construction with two argon-filled chambers, Low-E coatings on three glass surfaces, and frames that hold their shape when the wall behind them hits 150°. Installed to a written standard by people on our payroll.
- 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
Why valley homeowners choose us
We never subcontract — ever
100% W-2 veteran-led employees. The national window companies sell the job and hand it to subcontracted crews; the team that measures your openings is the team that installs them, and the only company on the hook is us.
Double lifetime warranty
Materials and our workmanship, covered for as long as you own the home. Not prorated.
Built for the Mojave
Glass packages and frames specified for 115° summers and relentless UV — not a national spec sheet.
Honest, same-day pricing
One visit, one written price, no four-hour pitch and no 'today only' pressure discounts.
Permits and HOA handled
We pull Clark County permits and prepare HOA architectural submittals for you.
Energy math, not guesses
We model your cooling load so you know what the upgrade should save before you buy.

Frequently asked questions
What makes a good window company in Las Vegas?+
Three things: the glass package is specified for desert solar heat gain rather than a national catalog, the installers are employees instead of subcontracted crews, and the warranty covers both product and labor in writing. Ask any Las Vegas window company for their NFRC solar heat gain coefficient, who physically installs, and what the labor warranty says.
Is Beyond Energy a licensed and insured window contractor?+
Yes. We are a licensed, bonded, and insured Nevada contractor, veteran-owned, and based in Las Vegas. We pull the permits ourselves and handle Clark County inspections as part of every window replacement project.
Do you use subcontractors?+
No. Every window and door is installed by our own W-2 crews. That is why we can put a lifetime workmanship warranty behind the install — the people who did the work still work here.
How much do replacement windows cost in Las Vegas?+
Most valley homes land between roughly $650 and $1,300 per opening installed, depending on size, operation style, and whether the job is a retrofit insert or full-frame replacement. We publish a full cost breakdown and quote every opening line by line before anything is ordered.
What areas around Las Vegas do you serve?+
The entire valley — Las Vegas, Henderson, Summerlin, North Las Vegas, Spring Valley, Enterprise, Paradise, and Boulder City. Consultations and installs are available in English and Spanish.
