Greg Amundson spent about 30 years building custom wood-framed houses near Lutsen on Lake Superior.
That career came to halt a decade ago, during the Great Recession of 2008-2009, when he was caught holding three high-end houses he had built on speculation, just as buyers disappeared.
Amundson, 58, salvaged the housing business by turning into a rental manager.
A longtime garage tinkerer, Amundson decided to start his next business by inventing an alternative to caulking. The process, which can be messy and imprecise using a caulk gun, had always bedeviled him. It often "looked like a monkey installed it," Amundson recalled.
So one night, while lying in bed and worrying about his housing business, Amundson's thoughts drifted to caulk. There must be a better way.
"I tried to come up with an easy, professional-looking design that would allow anyone to use it and also look perfect when installed," he recalled. "The 'wedge-shaped' idea surfaced about 4 a.m. … and I started drawing. I did not sleep the remainder of that night because I felt like I came up with something exciting."
But coming up with an idea is only part of the equation. "Another key part of this was my search for an extruder who would work with an inventor," Amundson said. "Most are reluctant, since inventors can be expensive and time consuming. Gary Noble at Bio-Plastic Solutions in Blooming Prairie was intrigued. We would not be where we are at if not for his help."
Amundson began selling the product as EasyCaulk on Amazon in 2013. Sales were slow. He attributed it to having the word "caulk" in the name, stirring up memories of bad caulking experiences for do-it-yourselfers.
