Since 1931, DeWitt Products Company has been a manufacturer of roof coatings, driveway sealers, and caulkings.

DeWitt Products Company invented a wet/dry roof cement ("Wetstick") and tub and tile caulk ("Dewk") for the industry.  Being innovative and maintaining the best quality in the industry has set DeWitt's apart from the competition. 

In 1987, DeWitt Products Company switched from asbestos products to totally non-asbestos products.  Once again, DeWitt has proven to lead the industry in non-asbestos technology and quality.
