Johnson’s Insulation responded promptly and came out to assess the crawlspace dangling insulation and rodent droppings issues. Contractors were sent the next day to remove old insulation and install missing insulation wires to keep them in place. Foam were also sprayed in the seams area. The whole crawlspace was also sanitized. All were finished within a few hours. Really happy with their work. Highly recommended

Johnson’s Insulation did a fabulous job of removing our old insulation and cleaning and sanitizing our attic. Once cleaned, they added new insulation and were very thorough in their work. We were happy with the completed job.

They responded the same day and came out quickly to review what I needed. It turned out I didn’t actually need what I initially thought, and instead of trying to charge me for unnecessary work, they gave me a helpful suggestion at no cost. Highly recommended—I’ll definitely use them again for any roofing or insulation needs.
