M&J Insulation was built by two best friends from Mountain Lake, Minnesota, with over three years of hands-on experience in spray foam insulation.

After years of working in the industry, we decided to start our own company with a simple goal: do quality work, treat people right, and build lasting relationships along the way. We believe strong connections matter just as much as strong insulation.

We specialize in spray foam insulation for residential, agricultural, and commercial projects. Whether it’s a home, shop, or farm building, we focus on clean installs, attention to detail, and long-term performance on every job.

Based in southern Minnesota and willing to travel, M&J Insulation is committed to growing the right way by earning trust, delivering consistent results, and standing behind our work.
