Jeff (L) and John Alexander are owners of Alexander Company.

Few window companies earn the prestigious Diamond Certified award, which means they’ve been independently rated Highest in Quality. Even fewer can also claim more than 40 years of industry experience, but that’s exactly the case for Alexander Company. According to co-owner Jeff Alexander, this longevity is important for providing customers with peace of mind and ensuring their satisfaction throughout every step of their window projects. “We often visit homes to repair problems caused by other companies that are no longer in business,” he explains. “Our customers don’t have to worry about that with us—they know we’ll still be here if they ever have an issue in the future.”
Alexander Company installs all types of 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, fiberglass, wood and aluminum windows made by leading manufacturers such as Milgard, Simonton, Marvin, Andersen and Integrity.
Unlike less experienced window companies that focus solely on selling products and rely on subcontractors to perform installation work, Alexander Company utilizes its in-house staff of professional installers to handle every phase of its clients’ window projects. “Whether it’s retrofit or new construction, we do all the installation work ourselves, which saves our customers time and money,” says Mr. Alexander. “We also do all our own framing, trimming and stucco work. Our customers appreciate having everything under one roof.”
Another distinguishing attribute of Alexander Company is its comprehensive approach to quality control, which includes emphasizing safety and industry innovation on a continuous basis. “Quality control is very important to us, so we conduct weekly installation and safety meetings to update our staff on cutting-edge installation methods and products,” says Mr. Alexander. “Our goal is to always be at the forefront of what’s coming into the market without disregarding what has worked well in the past.”
