Custom Metal Fabrication & Gutter Supplies

Established in 1962.


Thompson-Mathis Metal was established in 1962 by Davis Thompson, who supplied sheet metal for fabrication shops, HVAC and sign businesses. In 1993 when Davis was ready to retire, John Mathis, a long-time family friend purchased the company, added gutter products to the inventory and shortly afterward acquired The Dieckmann Company to sell downspout elbows nationally. In 2004, Elizabeth Mathis took over the family company, purchased K-style and Half-round gutter machines, hired and trained employees to do metal fabrication, and began marketing custom roof accessories.

I’ve been coming here since I was a kid and have been a customer for 20 years. My Dad has been a customer for 40 years and Thompson Metal has been our main supplier for gutter supplies and our only supplier for sheet metal and metal fabrication.
