Blake came to the house and assessed the attic and gave me several different options to choose from. He ordered the insulation, had it delivered, prepped the attic, and installed the installation. The house is significantly cooler, and even in the middle of the afternoon on a hot summer day, the house is comfortable without any AC needed. Very happy with the result, couldnt recommend Terrawatt enough.

Excellent customer service and installation from the guys at Cooper Insulation!…read more Fast, efficient, friendly. Owner Lee did the preliminary inspection and estimate, and followed up almost immediately about scheduling a work date, which we did, and now it's done, in the blink of an eye! Very unusual, by Maui standards, in my experience. We have, at last, a warm home, and nothing but the highest recommendation for Cooper Insulation!

I had a whole-house fan installed in my attic but the lack of insulation up there meant that it was…read morereally loud on top speed. I had considered buying insulation and installing it myself, but I'm old, mobility challenged and knew that it would take me months to complete the job on my own. I also had no idea what it would cost to have it professionally installed. I found Cooper Insulation on yelp, went to their website and sent a message. I got a phone call response almost immediately. The estimate for fiberglass insulation in my attic crawl space was well within my budget so I waited about a week while they fit me into the schedule. A team of employees arrived at a little after 7 a.m. and acted like a bucket brigade, ferrying pieces of insulation to the younger, more able-bodied members up in the crawl space. The job was done quickly and efficiently. They cleaned up after themselves and were on their way. The job cost exactly what was estimated. I could not be more happy. Not only is the whole-house fan's noise muffled by the insulation, but I am looking forward to my house being much cooler for their efforts. If you need insulation, these are the folks to call.
