Serving Customers and Community

Greg Amundson describes himself as a “garage inventor.” He went from creating solar energy at age 14 by heating water with a piece of glass in the rays of the sun to inventing and patenting InstaTrim®, THE universal trim solution.

Amundson invented InstaTrim® because he was tired of seeing caulking that “looked like a monkey installed it.” He was determined to create an alternative that is user-friendly and looks good every time. As a result, do-it-yourselfers across the country are trimming their home improvement projects with less mess and stress.

Greg owns and operates his company, CornerFlex, Inc., with his wife Betsy out of their home in Scandia, MN. A seasoned marketing and project manager, Betsy is instrumental in moving the business forward with a commitment to customers and community. Together, they make life easier for do-it-yourselfers!

Betsy and Greg are proud of the fact that InstaTrim® adhesive trim strips are a healthier alternative to caulk. They are non-toxic and made of PVC, which doesn’t require curing, so there are no toxic and smelly fumes. The product is also environmentally friendly, leaving very little waste and the packaging is 100% recyclable.

This husband and wife team work together and serve together, donating their time and product to Operation Honor – Veteran Proud, a non-profit organization that hires veterans to make hand-crafted burial and retirement flag cases. InstaTrim® provides the perfect seal for the cases.

The Amundson’s are honored to serve you and all of their customers who are making caulking easy across the country with InstaTrim®!
