  • I was and still am very impressed and happy about the insulation installed in my attic. I can feel the warm air staying in and seeing the snow on roof not melting away so fast as the attic is well insulated. I would highly recommend Dolphin insulation to everybody.

  • I hired Dolphin to make my poorly insulated older home more energy efficient. I am so glad I did! They did an excellent job! Both technicians, Chris and Dustin, performed all the work and did an impressive job! They arrived on time, super professional, knowledgeable, courteous and they took time to ensure my home was not a mess! I couldn’t be happier! Thank you Dolphin, Chris and Dustin!

  • So many wonderful things to say about this company! From the first time I called to see about scheduling I was blown away with the helpfulness of the individual I spoke with. She was anticipated my needs, spoken knowledgeably about our job and was even able to get us onto the schedule in the timeframe that worked for us! Once the crews showed up to do the job the service got even better! They were professional, checked in to make sure we were updated on the project/answered all our questions, and very clean in the job. They finished when they said they would and actually provided us a revised quote once they discovered part of our house was insulated from a precious addition. Would recommend this company time and time again- you won’t be sorry!

  • Dolphin Insulation replaced the insulation in our 2nd floor/attic. We are very pleased with the result. Ryan, the on-site project foreman took the time to explain the work as it progressed so that our questions were answered daily. He and his team were friendly, knowledgeable, and careful with our home. We would highly recommend Dolphin if you are serious about insulating your home.

  • We used Dolphin Insulation for multiple weatherization items around our house including air sealing, blowing cellulose insulation, etc. From the first contact to schedule the job, to their professionalism, to the quality of their work, Dolphin as a whole is a fantastic group. Highly recommended.

  • Chris and his team were great. Did fast, efficient work, cleaned up after themselves and were unobtrusive to a family working from home. A great experience!

  • We thought Dolphin Insulation was great! We had little to no insulation in a home we recently bought. Losing heat and central air running constant was an issue that they corrected for us. We are seeing a huge difference this week with the central AC. Thank you again!!
