We’re committed to helping you get the best ENERGY STAR value for your budget.
Although we now have the ability to service the majority of Minnesota, Green Source Inc. is family-owned and operated right in Little Falls, MN. Having worked as professionals in the window replacement and building industry for a combined total of more then 40 years.

We have known since our companies incorporation in 2012 exactly the qualities the company must retain and present to our valued customers. We treat every customer uniquely according to their energy needs and budget. We NEVER OVER SELL a customer. We almost always suggest that "the best" is always the "best choice" when making ENERGY STAR decisions for your home, while at the same educating and clarifying the need and possibilities of minimum and maximum insulation values and efficiency.

Other companies sell and service windows, but our sales and service is a step above the competition. Why? Because your Green Source representative has your best interest, as well as your weatherization needs and personal budget in mind; proving our standard of courtesy before offering easy financing or a final price.  We invite you to get a few quotes before calling us so we can show you the difference.
