The Best in Windows & Siding in Houston

Allstate Siding & Windows Inc., was founded in Houston, Texas, by James C. LaGrappe, Sr. In the 1970s, Jim began his career selling windows and vinyl siding by walking door to door. Jim’s experience and knowledge was handed down to his son, Jimmy LaGrappe, Jr., and daughter, Mary LaGrappe. Together, the three of them are the driving force behind this family-owned company. The success of this company is measured by the lasting relationships with their customers and the quality of their products and services. They take pride in having the majority of their sales come from previous customers and referrals.
