Critical: Responsiveness, Value
I would not recommend them, because they charged too much for a return trip when they did very little and, Amy was rude and didn't have the courtesy to return my calls.

Coast insulation did my new construction project consisting of a main residence and detached garage and apartment. Clark was responsive and helpful with all my questions, and their crew showed up on time and completed the job efficiently and with care and attention to detail. I was working on the house while the insulation crew was there, and during conversation with one of the crew learned they appreciate working at Coast over another insulation company because they treat their employees well. In my experience, happy employees do better work.
