Integrity: A Southern Illinois Legacy of Building and Trust Every community has families whose name becomes synonymous with hard work, honesty, and a promise kept. In Southern Illinois, that name is Blumenstock. For more than two decades, the Blumenstock family has built not just homes and businesses, but trust and community. Through the vision of founder David Blumenstock and the continued leadership of his sons Caleb and Trevor, Integrity has grown from a small-town contractor into a family of businesses and divisions recognized as Southern Illinois’ Trusted Building Contractor. Humble Beginnings in Crab Orchard, IL The story begins in the small village of Crab Orchard, Illinois, nestled in the heart of Williamson County. Here, David Blumenstock laid the foundation for what would become Integrity. With little more than determination, a passion for quality workmanship, and the courage to build something lasting, David set out to serve his neighbors the only way he knew how—by treating every project like it was his own. In those early days, Integrity was not yet a household name. But it quickly became one because of David’s unwavering principle: always put people first and stand behind the work. Whether it was repairing storm damage, constructing a new home, or maintaining a family business, David approached every task with the same values: honesty, reliability, and craftsmanship. Word spread across Crab Orchard, then to the nearby towns of Marion, Carterville, Herrin, Johnston City, Harrisburg, and West Frankfort. Before long, Integrity was not just a business—it was a trusted part of everyday life in Southern Illinois. Building Beyond the Basics As the years passed and the community’s needs grew, so did the Integrity brand. What began as Integrity Built expanded into new divisions:

• Integrity Maintenance, providing on-demand service for commercial buildings, from repairs to inspections and remodels.
• Integrity Services Southern Illinois, the full-service construction and maintenance division now headquartered in Marion, IL.
• Specialized divisions tackling everything from roofing and siding to storm damage restoration and insurance claim assistance.

Each expansion was born from a simple observation: Southern Illinois families and businesses needed more, and the Blumenstocks were ready to answer that call. “We never set out to build an empire,” says Caleb Blumenstock. “We just kept listening to what people needed, and we kept showing up with integrity. That’s how every division of this company was born.” From Crab Orchard to Marion, IL The family’s dedication eventually outgrew the small-town headquarters in Crab Orchard. To serve more communities and expand their reach, Integrity moved into a modern facility at 1201 Hoover Road in Marion, Illinois. This move was more than just a change of address. Marion, known as the “Hub of the Universe” in Southern Illinois, offered a central location that allowed Integrity to serve a 20-county region stretching from Mt. Vernon in the north to Cairo in the south, Belleville in the west to Harrisburg in the east. From their Marion headquarters, the Blumenstock family built a company that could serve not only homeowners but also large commercial clients, all while maintaining the personal touch that defined their beginnings. The People Who Built Integrity The real story of Integrity, however, is not just about facilities and growth. It’s about people. The families of Marion, Carterville, Herrin, Johnston City, Harrisburg, West Frankfort, and dozens of other small towns and villages across Southern Illinois are the ones who put their trust in David and his sons. Every project completed was a partnership, and every handshake was a promise. In return, Integrity gave back—not just with strong roofs and sturdy walls, but with stability, reliability, and an unwavering presence in times of need. When violent weather tore through neighborhoods, Integrity showed up with tarps, boards, and crews ready to make things safe. When businesses needed trusted maintenance, Integrity was only a phone call away. “Our father always told us: if you put people first, success will follow,” reflects Trevor Blumenstock. “That’s how we’ve run this company, and that’s why the name Integrity means something in Southern Illinois.” Southern Illinois’ Trusted Building Contractor Today, Integrity Services Southern Illinois stands as a testament to what can be built when a family commits to values over shortcuts and people over profits. From its roots in Crab Orchard to its home in Marion, from small-town projects to major commercial builds, the Blumenstock family has earned its place as Southern Illinois’ Trusted Building Contractor. It’s not just a brand—it’s a legacy. 📍 Address: 1201 Hoover Rd, Marion, IL 62959 📞 Phone: (618) 422-0001 Hashtags #IntegrityServices #SouthernIllinois #MarionIL #CartervilleIL #HerrinIL #WestFrankfortIL #HarrisburgIL #BlumenstockFamily #TrustedContractor #BuildingWithIntegrity #SouthernIllinoisStrong #StormDamageRepair #IntegrityBuilt
