WinDor Specialty Doors

A Shared Purpose

In Southern California in 1990, two brothers-in-law founded WinDor and proceeded to build a company that has been recognized repeatedly for their high quality standards and exceptional customer satisfaction ratings. In Northern California in 1994, two brothers founded Brothers Home Improvement and began their own quest to uphold high standards of quality and customer service. In 2023, these story lines finally crossed paths and we now work together to continue to bring the best in product and service to the industry.

An Exclusive Design

WinDor’s Multi Slide and Folding Door Systems showcase the company’s innovation. The strength of rigid aluminum framing is combined with the durability and low-maintenance qualities of vinyl capping—a unique feature not offered by other manufacturers.

Name(Required)

WinDor was established in 1990 by two brothers-in-law, who developed a reputation for quality doors and satisfied clients in Southern California. And four years after that, two brothers began Brothers Home Improvement, Inc. in Northern California and continued with the same attention to high-quality service and products. 

And two years ago, we, at Brothers Home Improvement, Inc., partnered with WinDor to keep offering the best doors to homeowners in the industry, and this is how our partnership began and still continues with WinDor.
