About Us



Welcome to Gutterworks Mfg Inc.


Front Street Manufacturing (now Gutterworks Mfg, Inc) was founded in late 1998. We began in one small building in the East Central Iowa town of Montezuma. We have since moved to a larger facility in Barnes City, Iowa and have grown to over 20,000 sq. ft. of production and warehouse facility.

Founder Dennis DeNooy worked as a Seamless gutter installer for many years, where he gained knowledge and experience in the seamless gutter business. The business originated with a small product that he developed and patented called the "Handler". This steel, powder-coated hinge allows you to raise and lower your downspout extensions during lawn maintenance. We have sold thousands of these inexpensive but effective hinges all across the United States. Many of our seamless gutter installation customers use them on every job! 

In September of 2020, after working in the gutter industry since 2012, General Manager Randy Simmons along with his wife Cedar, purchased the company and look forward to continue serving our existing customers as well as building new relationships.
