ABC Window Contractors, Inc. Comparative Summary

ABC Window Contractors, Inc. relies on satisfied customers as its foremost source of publicity, says co-owner Alex Koustas. Those customers have kept ABC in business for over a half-century, burnishing its reputation as one of the Bay Area’s leading suppliers of custom windows and sliding glass doors.

While most window companies sell and install products they buy from the manufacturers, ABC is one of the few companies on the West Coast that manufactures its own windows and doors. To do business with them, therefore, is to do business with seasoned industry experts whose knowledge reaches from the earliest stages of manufacturing right up to the final installation and follow-up.

ABC Windows owns and operates two state-of-the-art facilities in Central California. Its windows are fabricated from vinyl made by industry-leader VEKA and are installed by the company’s own factory-certified crew, headed by Robert Vogt, a certified Installation Masters Instructor with the American Architectural Manufacturers Association (AAMA).

ABC also sells and installs top-rated Marvin wood windows.

All ABC installers are accredited by Installation Masters, a national training program. Though participation in Installation Masters is not required by the industry, ABC chooses to enroll its employees and pay all fees associated with their coursework and testing. Few window companies place such a high premium on ongoing employee education.

ABC rejects high-pressure tactics, says Koustas, preferring instead to lay out all the relevant information up front and leave customers to make their own decisions. Estimates are always free, clear and comprehensive.
