I’m a realtor helping sell a home that needed a serious attic cleanup, and Johnson’s Insulation did an outstanding job. The attic was in really bad shape — tons of rodent droppings, holes everywhere, and old insulation that needed to be removed. Their team came out quickly, cleaned everything thoroughly, sealed up the attic, and installed new insulation. They worked efficiently, left the place spotless, and their bid was very reasonable compared to others. Super professional and reliable — I really appreciate their work and would highly recommend them!

Excellent work by Miquan and his team! They completed attic insulation, spray foam for my loft, and full duct replacement. Miquan was very knowledgeable, took time to explain what my house needed, and was always prompt with responses. The team was extremely professional throughout the project - respectful of my home, arrived on time, and maintained a clean work area. They actually finished the job ahead of the promised timeline, which was a pleasant surprise. Quality workmanship throughout and I’m already seeing improved comfort and energy efficiency. Highly recommend for insulation and ductwork services.

I am able to choose only 3 items that Thumbtack provided, so I am adding both work quality and value too. Amazing work, on time, and they were also able to come back to install the register which at the time of installation they werent able to do. I would definitely recommend to anyone to use their services. Thanks guys.

Miquan was very responsible and professional. They just finished the work. They did what they promised. He was a bit short on material estimate but we ending up working that up with him. The area that was being replaced with new insulation was not fully visible till they removed the old insulation. Overall good experience. The crew Guileremo and 2 others were good too. Guillermo is the supervisor to the 2 man crew who worked in the attic
