It was messier than I thought. They did not clean up well. They were nice and knew what to do. Patches were done very well.

They did the same thing as other quotes but for much cheaper and were very responsive to any concerns.

Jeffrey Bangs -Guardian Home Energy came and gave us a quick and accurate estimate. The work crew showed up preformed the work quickly, from start to finish within 3 hours. We immediately noticed the difference in how the house held in the heat. Thank you!

The guys did a great job, cleaning up the old insulation and then reinstalling new insulation. They were professional and cleaned up after. I would recommend them.

They were on time, professional, and did the insulation work for the quoted price. Russel, Mark, and Crew were fantastic. You can not see the holes at all, it is amazing!

They were ontime, professional, and did the contracted work for the quoted price. There was a slight hiccup at the job start, but they were great at communication and resolved it quickly. Basically I had a slight misunderstanding of where a vent would be placed. This company is what you look for in a contractor. I would absolutely use them again.

We were considering spending over $50,000 on 7 new double French doors. Following Russellâ s survey we found we did not need to do so to help solve our HVAC issues. We now have his 17 page report including guidance regarding HVAC equipment, changing ductwork, solar equipment, insulation and recommended companies to call to get quotes as needed. We found his energy survey worth every penny.

would like to say that they did a really good job. But I would like it better if the people doing the job would of let me know when they were dont vacuuming out the insulation so I could look at it and see if I liked the job. Second when they sprayed the disinfectant they did not warn us they were doing it to see if we were ok being in the house while spraying the disinfectant . Great job overall.

This was a very good experience. Russell was professional and knowledgeable. He was precise in explaining the job to be done and why it should be done in a certain way. The work crew was excellent. I reviewed the work as it progressed. They were polite and conscientious. They protected the floors and house and cleaned up nicely. I chose this company from Angie's List. I made the right decision in engaging Guardian Insulation.

Russell was very professional, well informed and took the time to explain the entire process to us. He also adjusted the price when insulation in a room addition was not necessary. The crew arrived on time, cleaned up after the work and wore masks when interacting with us (important due to Covid). We have and will recommend them to others.

Russell was very professional and adjusted the price when they didnâ t have to do one walk which already had insulation. I was impressed with his honesty. I would highly recommend them and wouldnâ t hesitate to use them again.
