A Colorado family-owned manufacturing company that has been in business since 1936. We geek out over a better way to caulk and stain. Making a ‘Good, Better, Best’ product range just doesn’t make us jump up and down. We’re passionate about making the highest performance product possible for each project and have innovation coursing in our blood.
EXPLORE OUR HISTORY
Donald J. Burch registered the Colorado Steel Sash Company despite a struggling depression economy. He knew there was a market for an elastic-glazing putty that didn’t oil separate in the can.
Don added caulking to his product list, built his first manufacturing plant, and began turning out both caulk and putty in 100 and 200-gallon used bread-dough mixers.
By the 50s, Sashco was operating seven different warehouses across the U.S. and opened a second manufacturing facility in Seattle, Wa.
In 1954, Sashco’s visionary perished in a plane crash. Don left behind a pregnant wife, a 4-year-old son, and a thriving business. For a decade, innovation at Sashco stopped.
Don’s widow Alice became determined to preserve the company for her children and took over management in mid-1964.
Les Burch, Don and Alice’s son, joined the company as a graduate chemical engineer and subsequently became president.
Presently, Sashco, still a family business with Les’ sons involved, manufactures and markets sealants, caulks, and stains for DIYers and contractors alike.
