Our Story

Owned and Personally Operated by Guy and Adam

NG Windows and Doors is a mobile window, door, and glass installation and replacement company serving Southern California. Every project — from the first phone call to the final walkthrough — is handled personally by Guy and Adam. There are no subcontractors and no rotating crews, so the people who quote the job are the same people who show up and install it.

We opened in August 2026 with a simple goal: give homeowners and businesses across LA County, Orange County, and the western Inland Empire an honest, straightforward alternative to the big sales-driven window companies — free on-site consultations, clear pricing, and advice you can trust, even when that advice is "you don't need a full replacement."

What We Believe

How We Work

Honest Advice First

If a repair is the smarter call, we'll tell you — even when a replacement would cost more and pay us more. We'd rather earn a repeat customer than a single upsell.

No Middlemen, No Delays

No subcontractors and no rotating crews — Guy or Adam measures the job, quotes the job, and installs the job. What you're told on the phone is what shows up at your door.

Free, No-Obligation Quotes

Every project starts with a free on-site consultation — measurements, material options, and a clear price before any work begins. No pressure to sign on the spot.
