Delivering Excellent Customer Service Has Always Been And Will Always Be Our #1 Priority.
Robert N. Karpp Company was started in 1979 by Robert (Bob) N. Karpp with the goal of providing superior customer service to drywall contractors. It began in a small warehouse in South Boston with just a few employees, a pickup truck, and some slightly used boom trucks. Bob’s son Rob joined the company in 1980 and, together, they grew Robert N. Karpp Company into the largest independent drywall supply yard in the Boston area.
The company continued to grow and welcomed Bob’s grandson, Bobby, in 2008 after he graduated from college. We now have three generations working together to deliver the best products and customer service in the area, and have recently become part of the GMS family. Today, Robert N. Karpp Company services all of Massachusetts, all of Rhode Island, southern New Hampshire, southern Maine, and Connecticut.
