Alexander Company installs replacement windows and doors for residential clients in San Mateo County and San Francisco. In addition to its professional installation capabilities, the family-owned and operated company maintains a large showroom in Burlingame that carries a wide variety of products, including vinyl, aluminum, wood and fiberglass windows made by leading manufacturers such as Simonton, Marvin, Anderson, and Milgard.
Owners John and Jeff Alexander are second-generation proprietors of Alexander Company—their father established the business in 1971 and taught them everything he knew about installation, sales, and management before retiring two decades ago. “This company has a reputation for working with integrity and quality, and my brother and I work hard to uphold that,” says Jeff Alexander. “We stand behind our products on both the installation and sales sides, and we always keep up-to-date with industry standards and trends.”
Alexander Company’s partnerships with the window industry’s top manufacturers allow it to act as both the dealer and contractor on its clients’ projects, which ultimately saves time and money. “This is a one-stop shop—instead of purchasing windows and hiring a subcontractor to install them, our customers know they can trust us to handle everything ourselves,” says Mr. Alexander. “We take responsibility for every detail.”
“We’ve learned to always put ourselves in our customers’ positions, so we do everything we can to ensure their satisfaction and make their experiences as positive as possible. Our number one goal is to utilize our window and door expertise to help our customers create their ideal homes.”
