About JSI

"Local Industry Leaders"

"I have worked with Terry St. Clair and Jack St. Clair, Inc., since 1985. Terry is one of the most hard-working contractor owners I have worked with. Never questioned his integrity or workmanship, a man of his word. I would truly recommend his company for any pipe laying job. I would consider Jack St. Clair, Inc., as one of the local industry leaders in the Roanoke Valley. I have been blessed to have worked with Terry all of these years."
