A look at American Window Systems’ Napa storefront

American Window Systems, Inc. provides and installs energy-efficient replacement windows and doors for residential clients in Napa, Solano, Sonoma, and Marin Counties. The family-owned and operated company is an authorized dealer for Simonton, Cascade, PlyGem, WeatherShield, Fleetwood and several other leading manufacturers. It can complete most installation jobs in one day, and it supplements its work with various warranties, including those that cover glass breakage and screen tear.

Owners Tom and Roberta Javorina say American Window Systems’ team is dedicated to making each client’s window installation experience a positive one. “Our sales staff is trained to help clients choose products that fit their needs and budgets, and our lead installers bring more than 50 years of combined industry experience to every job,” says Mrs. Javorina. “We work efficiently, carefully and respectfully to complete projects on schedule.”

American Window Systems emphasizes the importance of customer satisfaction—approximately 80 percent of the company’s work comes from referrals, and Mrs. Javorina says it’s enjoyed a complaint-free streak on its contractor’s license of more than 35 years. “Our success is based on three factors: quality service, superior products and competitive prices.”

Company Philosophy

“We don’t believe in using high-pressure sales tactics. Our initial estimates are competitive and fair; we won’t start with an inflated price and try to coerce business by offering discounts. We respect our clients and take care of their needs throughout the entirety of their projects.”
