The Family Store with So Much More

Merwin Mason Supply Co.,Inc. was started in 1970 in an old tobacco barn in South Windsor. It later moved to the Chapel Road location where it is today. The company was started by Merwin Pola and his family with just one small pickup truck. Today we have a large showroom and a fleet of trucks with fork-lift unloaders for fast and safe delivery. We are still a family run company and strive to keep that "small business" quality that that gives you the outstanding, personal service you have grown to know and appreciate for the past 30 years.

Cultured Stone® by Owens Corning

Owens Corning Cultured Stone® products originated in 1962 when brothers Garrett and Floyd Brown of Vallejo, California saw the need for a new kind of building material. The entrepreneurial pair of plasterers developed manufactured stone veneer: exact replicas of natural stones used for building, cast in flexible molds and hand colored with iron oxide pigments. Made of lightweight aggregate materials, the veneers were approximately one-quarter the weight of full-thickness stone and could be adhered to most wall surfaces. Today, Cultured Stone® is available in more than 21 textures and more than 100 colors. We have samples of the entire line in our showroom.
