Very pleased with this company.
We were looking at adding insulation to our attic as it was quite low when we purchased the house (~6 inches). We initially discovered Comfort Insulation through a visit to Costco (they had one of those promotional stands on the way out) and looked online and heard both good and bad about Costco contractors / partnerships.
We moved on to get a few more quotes and were going to pay about the same or more for alternative companies we were interested in. We figured we'd take the chance as Costco would at least back their work in case something went wrong.
We're very glad we did. A sales representative came by to inspect the attic and then the work was done by two other individuals (Ashley and Dave). Ashley and Dave were both very courteous and clearly customer centric in their approach. They did exactly what they said they would do and Ashley even helped answer some of the questions I had about the work done.
As a bonus, the upgrade to our attic insulation actually made a difference in our home which made it seem like money well spent to boot.
Highly recommended for anyone considering to use their services.
