About our company

Happy CustomersBestoff Windows & Construction is committed to provide you with a great product and a professional and quality installation at a competitive price. We believe that the quality of the service and the quality of the windows go hand in hand. We want you to find the right window for your home, that’s why we’re offering free in-home design consultation and estimate.

We offer custom-made windows and doors which are built exclusively to fit your home. Additionally, we give you a transferable lifetime warranty for both the product and the installation.

Since 1996 we’ve installed roughly 156,000 windows and doors in our customer’s homes. Our BBB A+ rating, since 2001, hints at the quality of our work – but if that’s not enough we will happily provide you with references within your own neighborhood. It took Bestoff Windows & Construction only four years to become a leading Bay Area window replacement company thanks to our customer referrals and our focus on providing a great product and backing it with superior service.

We don’t require any deposits, down payments, or any progress payments. Your first, and last, payment is required only upon the completion of the job and upon your full satisfaction.

Bestoff Windows is able to offer a great window product at a low cost due to our large volume of sales. Each installer is hand-picked and trained by the owner, who has over 23 years of experience in window replacement; they are timely and courteous. Our quality work is backed directly by unprecedented customer service.
We carry all major brands of the vinyl window industry. Our prices are unbeatable on any style of window; we go so far as to price-match all competitors.
