TESTIMONIALS

What Our Valued Clients Say

"Showed up on time, did many extras free of charge to insure attic was properly insulated, and cleaned up after themselves. Service and product (blown in insulation) were stated as and have already seen 20% reduction in heating bill."

Jeff S.

"Steve Crumley of C&M Insulation, came to my home and gave me a great estimate to add insulation to my attic. I set up an appointment 2 days later. He gave me a time of 10 a.m. and he showed up at 9:45AM. The work was extremely professional. There was no interruption of other household activites during the spraying of the insulation. Steve did a remarkable job and I will give him 5 stars! I wish all contractors were as professional as Steve is. It was a pleasure to be his customer and I’d welcome his service at my home anytime! Thank you Steve Crumley"

Winston O.

"Steve contacted me immediately to setup a time to perform an estimate, then scheduled the install for 6 days later. They showed up on time, and finished the job earlier than expected. I had additional insulation blown into the attic, batts installed in the crawl space, and insulation blown into exterior walls; I am very pleased with all the work that was performed."
