Planning window replacement in Las Vegas
Your project is quoted individually after an assessment of opening sizes, selected products, glass specifications, and installation requirements. Request a written proposal for your home.
Most homes are finished in a single day. We pull the Clark County or city permit, prepare HOA submittals, and every installer on your property is a W-2 Beyond Energy employee — never a day-hire subcontractor.

How to tell your windows are the problem
You don't need a diagnostic to know. Rooms on the west side stay hot no matter where you set the thermostat. The glass is warm to the touch at 4pm. There's a haze or fog between the panes that no amount of cleaning fixes. Dust collects on the sill even with the window shut.
Every one of those is the same story: the glass package has stopped rejecting solar heat, or the seal has failed and the insulating gas is gone. Your AC is now paying for it, all summer, every summer.
Replacement windows are the one upgrade where Las Vegas homeowners feel the difference the same week they're installed — the rooms even out and the system stops running nonstop.
What's in our replacement windows
We specified this glass package for Southern Nevada — not a national spec adapted after the fact. Every unit includes:
- 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
Full-frame or retrofit — we tell you which one you need
There are two common ways to replace a window, depending on the existing frame. A contractor who only ever should explain why the recommended method suits your opening.
Retrofit (insert) replacement
The existing frame stays; we install a new fully-sealed unit inside it. Retains the existing frame without extensive stucco disruption. The right call when the frame is square, dry, and sound.
Full-frame replacement
We remove the window down to the rough opening, inspect and repair framing, re-flash, and set a new frame. Required for warped aluminum, water damage, or out-of-square openings.
No glass-only repair
We don't do glass repair. Foggy or cracked glass gets a complete new window, so the frame, seals and glass are all new and warrantied together.
Size or style changes
Converting a small bathroom window to an egress size, or a slider to a casement, means structural work. We handle framing, permits, and stucco patching in-house.
Installed in one day, most homes
Your windows are custom-built to laser measurements while we pull the Clark County permit and prepare any HOA submittal. When they arrive, one crew handles the whole house.
Nothing is subcontracted, so nobody hands your job to a stranger halfway through. The crew lead who measured your openings is on site the day they go in.
- 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

Recent window replacements around the valley
A sample of the work and what actually changed for the homeowner. Every one of these was measured and installed by our own W-2 crew.
Anthem, Henderson — 14 windows, one day
Failed 1998 builder dual-panes with fogged seals throughout the second floor. Full retrofit in triple-pane Low-E. Upstairs bedrooms stopped running 6° hotter than the thermostat, and the July bill dropped about a third year over year.
The Paseos, Summerlin — 9 windows + HOA approval
Big west-facing glass taking full afternoon sun off Red Rock. We prepared the architectural submittal with approved frame color and grid pattern, got it through in one round, then installed in a single day.
Aliante, North Las Vegas — 11 single-panes
Original single-pane aluminum, the worst combination in the valley. Full-frame replacement with framing repair on two openings. This is the profile where the cooling-bill drop is largest and fastest.
Spring Valley — aluminum-to-vinyl conversion
1980s aluminum frames conducting heat straight into the living room. Converted to thermally broken foam-filled frames; the wall-adjacent hot spot next to the slider is gone.
Mountain's Edge, Enterprise — 8 windows
Newer build with code-minimum glass doing almost nothing. Full replacement of 8 windows with Low-E units built for west-facing sun.
Boulder City historic district — 6 windows
Decades of UV damage on original single-pane sashes. Historic-appropriate frame profiles, city permit pulled by us, modern triple-pane performance behind a period-correct look.
Who else you're probably getting quotes from
Search "window replacement Las Vegas" and you get three real local installers, two national retailers, and a page full of directories and affiliate review sites that have never set foot in the valley. Homeowners typically end up comparing us to the same three names.
Renewal by Andersen builds a good window at its own product and installation options after a multi-hour in-home presentation. Window World offers entry-level dual-pane packages and franchise install crews. Desert King Windows is local, which is the right instinct — we just also put the crew on our own payroll and the glass spec in writing.
We publish honest side-by-side comparisons of all three, including where a competitor is the better fit. Also worth reading: DiBella Windows.
Why homeowners choose us over the national guys
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 project quotes
One visit, one written quote, no four-hour pitch and no 'today only' pressure.
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.
Window replacement across the Las Vegas valley
We install throughout Clark County and know each jurisdiction's permit path — City of Las Vegas, Henderson, North Las Vegas, and unincorporated county. HOA-heavy neighborhoods in Summerlin and Anthem get the architectural submittal package prepared before we order glass, so approval never stalls your install date.
Local service areas: Henderson, Summerlin, North Las Vegas, Spring Valley, Enterprise, and Boulder City.
Frequently asked questions
How is my window replacement proposal prepared?+
Your project is quoted individually after an assessment of opening sizes, selected products, glass specifications, and installation requirements. Request a written proposal for your home.
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?+
The whole window. We don't do glass repair or glass-only replacement — we install complete new windows built for Las Vegas heat, so frame, seals and glass are all new and covered together.
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.
