Our Commitment

Quality Without Compromise

At Lexmark, quality is not a department — it is a culture. Every window and door that leaves our facility has passed through multiple stages of inspection, from raw material verification to final assembly checks. We use only virgin vinyl compounds — never recycled materials that compromise structural integrity — ensuring your windows resist warping, fading, and cracking for decades.


Our Onix series features black virgin vinyl that is solid color throughout the profile — not painted, not laminated. The color will not peel, fade, or chip, even under the intense Southern California sun.

Our Process

Precision Manufacturing

Our 15,000+ square foot manufacturing facility in Garden Grove houses state-of-the-art equipment for every stage of production. From CNC-controlled cutting systems to automated welding stations, every machine is calibrated for precision down to 1/16 of an inch.


Each team member is trained in their specific craft — cutting, welding, glazing, hardware installation — ensuring specialist-level quality at every station along the production line.

Step By Step

From Raw Material to Your Home

Every Lexmark window follows a rigorous production journey with quality checkpoints at each stage.

1
Profile Cutting
Virgin vinyl extrusions are precision-cut to exact measurements using CNC-controlled saws. Each cut is verified against the work order specifications.
2
Frame Welding
Corner joints are fusion-welded at 500°F, creating a seamless molecular bond stronger than the vinyl itself. No screws, no gaps — just solid, weathertight corners.
3
Corner Cleaning
Welded corners are precision-cleaned to remove flash material, creating smooth, factory-finished joints that look as good as they perform.
4
Hardware Installation
Premium-grade locks, operators, and balances are installed and tested. Every mechanism is cycled multiple times to verify smooth, reliable operation.
5
Glass Unit Assembly
Dual-pane Low-E insulated glass units are carefully set into frames with proper glazing tape and pressure. Argon gas fill provides additional thermal insulation.
6
Final Inspection
Every completed unit undergoes a comprehensive quality check — glass seal integrity, hardware function, dimensional accuracy, and cosmetic inspection before packaging.

REAL REVIEWS FROM REAL CUSTOMERS

Customer Reviews

“

Not sure why there are bad reviews because I was pretty happy with my experience. The turnaround time is super quick. They customized 11 windows for me in less than a week. And they installed all of them in a day. The quality seems good, and no different than what you would get with Milgard, except it is half the price.
