On a foggy morning in San Mateo, a homeowner waited—again—for a no-show contractor. The sliding doors she ordered six weeks ago had finally arrived, but no one came to install them.
Two hundred miles south, in Orange County, a young couple had a different problem: ocean air had corroded their aluminum window frames within two years. Their supplier? Based out of state. The warranty? Nonexistent.
Across California, stories like these are far too common. Long lead times, out-of-touch vendors, and poor after-sales support have turned dream homes into ongoing headaches.
At DOORWIN WINDOWS INC, we believe California deserves better. That’s why we’ve built something different: a statewide support network anchored by our California headquarters, backed by licensed local installers, and powered by a commitment to 48-hour technical response in 39 cities across North America.
We don’t just deliver California windows and doors—we deliver confidence.
In San Diego, a family renovating their coastal retreat had chosen off-the-shelf aluminum windows—only to discover corrosion setting in before their first summer was over. We assessed the damage and replaced the affected units with impact resistant windows CA, engineered specifically for salt-heavy air and high UV exposure.
When Beverly Hills homeowner Michael H. faced delays with a previous supplier, he turned to us in frustration. His custom sliding doors Beverly Hills had been sitting in crates for weeks because the original vendor had no installation support. Within 24 hours of his call, our licensed local team was onsite. Not only were the doors installed flawlessly, but our technician also recalibrated the locking system for smoother operation.
In Palo Alto, a tech executive was looking for complete quiet. He came to us after hearing about our soundproof windows Los Angeles projects. After a consultation, we delivered a laminated double-pane solution that transformed his home office into a silent, productive haven.
From Los Angeles windows and doors to Beverly Hills windows and doors, Luvindow has delivered over 120 tailored systems across California’s most demanding environments—each designed to meet specific architectural, climatic, and energy requirements.
