About Us

Front Street Manufacturing, Inc. Headquarters

Welcome to GutterWorks.Com, the web address for Front Street Mfg. Inc.  My name is Dennis (Denny) De Nooy, and I started this small company 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 14,000 sq. ft. of production and warehouse facility in the very small town 8 miles south of Montezuma.

I worked as a Seamless gutter installer for many years, where I gained knowledge and experience in the seamless gutter business. The business originated with a small product which I 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. We also have housing developers requesting them on homes when they install rain gutters.

Developing new useful products is what we enjoy and to date, we have developed 15 unique accessories which we manufacture and distribute to the gutter industry.
