Where Experience Meets Integrity in Flooring Inspection
TW Group Flooring Inspections is a family-founded, third-generation flooring inspection company serving Oregon and Washington, with consulting available worldwide. Since its inception, our mission has remained the same: deliver thorough, unbiased, and technically sound flooring inspections that empower homeowners, manufacturers, attorneys, and installers to make informed decisions.
Founded by respected industry educator Terry Weinheimer, our company earned a national reputation for accuracy, professionalism, and technical insight. In 2023, following Terry’s semi-retirement, leadership passed to his son Kevin Weinheimer, a certified flooring inspector with over 35 years in the floor covering and textile industry. Kevin now serves as owner and lead inspector, carrying forward the values of impartiality, detailed analysis, and continued learning that have defined our work for decades.

A Legacy of Excellence Since 1934
Our roots run deep. In 1934, James H. Weinheimer, a former chemist, entered the floor covering industry, establishing a family legacy that continues to this day. Later, his son Terry Weinheimer founded a specialized floor covering inspection firm in Oregon in 1990. In 1998, Terry’s son Kevin Weinheimer became certified and joined the family business. Today, Kevin leads TW Group Inspections, providing expert services throughout the Pacific Northwest and beyond, following Terry’s retirement. >Our History
