Where we differ from Window World
Window World competes on price, and for a rental or a flip that can be the right call. What we hear from Las Vegas homeowners is that the entry-level glass package doesn't move a summer power bill much, and that a franchise install can mean a rotating cast of subcontracted crews.

What you get either way with 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.
We'd rather you compare than commit early
Window World is a real company with real installations, and we're not going to pretend otherwise. The only claim we make is this: on desert-specific glass spec, on who physically shows up to install, and on whether labor is warrantied for life, we'll take the comparison every time.
Get both quotes. Ask both companies the same six questions. That's how you end up happy in five years.
Frequently asked questions
Should I get more than one window quote?+
Yes — get three. Ask each company for the U-factor, the SHGC, the number of Low-E surfaces, whether the install is retrofit or full-frame, and whether labor is warrantied. Once those are written down, the quotes become comparable.
Why are national window brands more expensive in Las Vegas?+
National brands carry heavy advertising spend, franchise fees, and commission-based sales structures, and that overhead lands in the per-window price. A local company running its own crews has a lower cost base for the same or better glass spec.
Is a cheaper window a bad window?+
Not always — for a rental or a flip, an entry-level dual-pane unit can be the right economic choice. For a home you're keeping through Las Vegas summers, the glass package is what determines whether your bill actually drops.
What should I never accept in a window quote?+
A price that expires when the salesperson leaves your driveway, a refusal to put U-factor and SHGC in writing, a warranty that covers materials but not labor, and any quote that doesn't state whether installation is retrofit or full-frame.
