German-engineered windows and doors built for Florida hurricanes, installed by the family that founded the company.

About

A&J Windowhaus is a family-run window and door company serving St. Petersburg, Tampa, Clearwater, and the surrounding Gulf Coast. Founded by Joe, who spent over 30 years in the window business in Berlin before moving to Florida, the company is now a partnership between Joe and his son Alex. Their name comes straight from those two. They specialize in residential hurricane impact windows and doors, commercial storefront systems, and curtain wall installations. All products are German-engineered, custom-fit to your home, and certified to meet Florida Building Code standards for wind-borne debris and high-velocity hurricane zones. The in-house team handles laser measurement, permitting, inspections, and installation. They've been serving the Tampa Bay area for over three decades.
