Merwin Mason Supply Co.,Inc. was started by Merwin Pola and his familyin 1970 in an old tobacco barn in South Windsor. The family had just one small pickup truck. The company later moved to our current location on Chapel Road. Today we have a large showroom and a fleet of trucks with fork-lift unloaders for fast and safe delivery. Nevertheless, we are still a famil- run company and we 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.
