5.0 Bruce L. Walnut Creek, CA

Insulating under a house is difficult work and they were very busy doing so with efficiency and quality. They brought in extra workers and got the job finished in short time. They were all very courteous, honest and hard working, especially Javier who was very professional and he kept me well informed from the beginning to the end of the project. They also came in with the best price for the work. I highly recommend them for whatever type of insulation work is needed for your home or business.

5.0 Virginia R. Concord, CA

Seemed knowledgeable, answered all my questions, price was competitive and cleaned up after themselves.

5.0 Jesse C. Martinez, CA

The project was my cathedral like ceiling in my garage that where not insulated the walls where all done already and finished. It was a seamless experience, Javier and his sidekick where prompt and inspected the project. Made sure we where on the same page and in agreement of any possible speed bumps up front. I have felt the difference already with the product one of three they provided, and I am very satisfied with cost to value and performance. Thanks to JM Insulation and Javier and his co-worker for making this a great investment and experience. JM Insulation should be happy to have them!

Javier was very helpful when providing the estimate for the job - answered all of my questions and explained the process from removal to replacement and measures they take to complete the job safely. I really appreciated Javier's patience with my questions. As far as the estimate it was extremely competitive and we ended up selecting JM Insulation. Once selected, they did an excellent job scheduling and communicating with. The job was performed on time and very professionally. I inspected the work each day and everything was tip top. It was a pleasure to work with Javier and the team!

5.0 Doug S. Pleasant Hill, CA

Very clean. They masked off the area where they were working to keep dust down and debris to a minimum. The job was completed in a timely manner and the work was done well. Great value.
