5.0 Karen H. Grover, MO

Pure Insulation was wonderful to work with start to finish. Mindy came out to bid the job. She was thorough and did an excellent job explaining what was needed to address the issue I was having. She provided options without pressured sales. Her crew was fast, incredibly tidy, and super polite. Pricing was reasonable for a top quality job done. I would definitely recommend Pure Insulation.

We had good information with Pure Insulation, Mindy, Paul and the crew were very professional and they cleaned up really well after them. Thanks.

5.0 Paul B. Ballwin, MO

This fairly new company tries to hire veterans. The crew who came were VERY impressive. HARD working team, REALLY nice fellows, VERY polite and did NOT use the foul language which sometimes seems common with construction crews. The cleanup was impressive, the care was excellent and they worked really hard for nearly two full days to complete the job. The owner was on site most of the time to make sure it was done properly. Cannot speak more highly of them and wish them well and future success!

5.0 Steven I. Chesterfield, MO

It was raining when they came to install so they have to come back to finish the soffits. But the house is noticeably warmer already so we are very happy. He was the most expensive contractor, but so far worth it!

5.0 Sieglinde S. Saint Louis, MO

Very courteous, efficient and cleaned anything afterwards. During the job covered the entrance to attic in plastic. Customer service was great. I could speak with them without waiting time on the phone. I would recommend this company

5.0 Cydney T. Saint Charles, MO

I spoke with the iwner Paul and told hom what i needed. He listened! And conveyed what i needed and expected to Erik and Charles. Erik and Charles came to do the work. Having over 40 years in customer service I know what good service is suppose to be. From the VERY MINUTE they showed up until the the time they left I was SUPER IMPRESSED! (PS. That hardly ever happens because I'm particular, of course!) Erik and Charles had impeccable manners and "showed" they cared! I am so impressed I could shout it from my roof top! It is the best service I have ever received from anyone. Thanks Paul, Erik and Charles! May God bless you MULTIPLIED!!!

Response from Company:

Cydney, it so very good of you to take the time to express your satisfaction with our work. We work very hard to make sure our customers get what they pay for, and set up and clean up is part of that bundle. When you asked if we covered up well the path ways to the access, I immediately noted that on the work order that Cydney is concerned about set up and clean up. Charles is always good at paying particular attention to work 0rders and am so glad your experience was good . May God richly bless and Keep you.

5.0 Bob H. Ballwin, MO

Very thorough and extremely knowledgeable. They spent alot of time inspecting my attic and surrounding structure- I really appreciate the time they spent explaining their findings and suggested course of action. I would say if you are looking for a cheap route and JUST insulation, go elsewhere. These folks are professionals. My A/C is already working half as much as it did before their workà ¢à  à ¦.

Response from Company:

Bob, sorry I did not see this till just recently, part of the down side of small business is keeping up with all the demands, but wanted to thank you so much for a vote of confidence , for our service, being comprehensive and completed to make a real difference in comfort and economy. sincere thanks Bob. Paul & Mindy Peterson Owners.

5.0 Ryan B. Saint Louis, MO

This company was wonderful. They were knowledgeable about my home issue and helped convince me that fixing my insulation would fix our issues. Besides adding around 10 inches of insulation in the attic, they added ventilation in the soffits to really help keep the attic cool and the rest of the house cool. They fixed the bathroom fan ventilation, as well as added a whole house fan cover. Our house hasn't been able to stay cool over the past 5 summers. The very next day, our house sat at 74 the whole day (and it was a 95+ day that day, too) Thank you Mindi and your great group of workers!

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
