Sierra Insulation Co Inc

Both our QII inspector and our County Building Inspector were very pleased with the job Sierra Insulation Co. did on our ADU. The county inspector walked in, and said, "This looks good. You would think insulation would be a fairly easy part of the building process, but so often I see it is not done correctly." Thank you, Sierra Insulation Co!

We found their service to be affordable, friendly, timely and thorough! Penn Valley, Ca

I have used Sierra Insulation for fifteen years. Good prices and service.

Not only did Craig not show up on an attic insulation estimate, no one picked up the phone when I called to see what was going on. Craig never called me back either - just plain stood me up. I left work early to meet him at my home for this appointment. Wasted my time.

Good crew, did a good overall job. Spray-foam insulation in our attic remodel which we opened up into a living space. Co$t came out higher than the original bid, but that was a communication issue on both sides. Make sure your bid is exactly what you expect & agree to up front to avoid surprises. Would hire them again.
