It All Began with a Squeegee, a Good Work Ethic, and a Dream

In 1947, Henry Ehrenkranz arrived in Houston with big ambitions, a Coast Guard uniform still in his closet, and a determination to build something of his own. Turning down the chance to take over his father’s successful New Jersey business, he instead purchased a struggling company called University Window Cleaners and transformed it into Texas Window Cleaning (now Texas Window Cleaning and Waterproofing—TWCW).


Armed with a squeegee, a brush, and a work ethic honed through years of service and study, Henry laid the foundation for what would become a family legacy.


What started as a modest window cleaning service has grown into a trusted name in building envelope care. Today, TWCW specializes in comprehensive maintenance, waterproofing, and restoration services, offering expertise far beyond our original scope.

A Legacy Built on Integrity and Excellence

Henry’s belief in doing things “the right way” remains our guiding principle. While our tools and technologies have evolved—from the slogan “Call the Doctor of Panes” on our first truck to cutting-edge LIFECYCLE360 facade assessment technology—our commitment to integrity, precision, and client satisfaction has never wavered.

Deep Roots in Houston

Houston welcomed our family in 1947, and we’ve never stopped giving back. Whether it’s supporting underprivileged children through charity events or fostering a positive work environment with employee benefits like 401(k)s and company barbecues, we believe in investing in people.

For us, strong relationships—with our clients, our team, and our community—are the foundation of everything we do.
