They did some insulation work for me, the work turned out fine.

Satisfied Customer

I don’t have any complaints. They sprayed our house for insulation. They were here when they said they would be and did what they said were going to do. We did notice a difference in our heating bill the following winter; it was a little bit lower. We were pleased with them and would recommend them.

Happy Customer

The work turned out just fine. We hired them to do some insulation work for us. They were easy to work with and I had no troubles with them. They charged me what they quoted me. Overall I was happy with the work.

Happy Customer

We hired them to insulate a garage ceiling and walls. The experience was quite good, they did a good job. They cleaned up well. Their pricing was reasonable.

Satisfied Customer

The company gave me a ballpark estimate over the phone. After I had called other establishments for price comparisons I selected RG to provide the service. They came out, looked at the attic and gave me a final estimate. RG arrived on the installation date on time. Before beginning work they placed protections on the carpet and flooring around the attic entrance. They completed their work in a timely manner and kept the house clean. The attic now has a good amount of insulation, the ducts are blanketed and the attic entrance has a seal.

Happy Customer

Due to a repair in our ceiling it was discovered that the insulation was woefully inadequate. Mike came out the morning he was to start his vacation and took measurements for an estimate. The completed (very detailed) estimate was emailed to me in a timely manner and an installation date was agreed upon. The gentlemen that were to do the work called to tell us that they would be about 15 minutes late (very considerate). Upon arrival they put down protective materials proceeded to do the work. They were very professional and very considerate; asking if they could use the facilities and warning me that there might be some noise. They even asked me if I would like to inspect their work, (I don't do attics), however I did notice a difference in the gas bill. After completion there was not a trace of workmen being in the house (bathroom included). I would highly recommend RG Insulation!

Happy Customer

Estimate was well priced. We added blown in cellulose attic insulation. Timely with sending out information for Xcel rebateCrew arrived on time and completed work quickly. Cleaned up well.

Satisfied Customer

Mike came out to provide an estimate to upgraded attic insulation to R50 and insulated a basement crawlspace. He was very straightforward and thorough in his recommendations. When I had questions about the cost effectiveness of R50 versus R60, he promptly answered my email. The RG Insulation crew showed up on time, did a great job (the crawlspace was impressive) and thoroughly cleaned up after themselves. It was a great experience as part of our getting ready to move into our new home.

Satisfied Customer

Called for estimate, needed blown in insulation in garage attic. Sales rep came out to measure. The work was done about a week later. Workers were very professional and clean within the work area.

Happy Customer

At first it was difficult to reach the person we needed as he was going out of town, but after that, they were accessible and reliable.

Satisfied Customer

Installed insulation in our basement crawlspace at a good price. Workers were on time, efficient and cleaned up after themselves. Supervisor stopped by during installation to make sure everything was ok. Was not informed that the insulation would smell like something had burnt, but the smell went away after a couple of days. Would recommend this company.

Happy Customer

I hired RG Insulation to install baffles and blow additional insulation in my attic. Everyone I dealt with from the salesman who quoted me the price to the two gentlemen who performed the work were very professional. They took care to protect my floors and prevent mess. They did an excellent job in a short period of time and then made sure I pleased with their work. Plus, their price was excellent as compared to competitors. Highly recommend!

They were pros, and it seemed like they were done in no time. They even cleaned up behind themselves all the way to the front door before they left, and we've definitely noticed a difference since having the added insulation.


They did good work and gave us a good price. They had the best price of anyone we got estimates from.


They came out the next day, Were on time, finished in less than an hour and cleaned up after themselves. Very professional.


I was very happy with Champion. They were quick to come by and give me an estimate for adding insulation to my entire attic and they were competitive in terms of their pricing. They were friendly, on time, and neat in their work.


They were professional and stood behind their work. This is good business practice! Wow, very impressed!


They did a very nice job, and I was happy with their work.


They were very polite and they were on time despite the weather. The total work was also completed in a hour and a half as promised. I would recommend them and use them again.


You won't ever regret using this company. We have used others that used shortcuts to save them money, and it's just not worth it. Spend the money and know you are getting the best.


They did great! They were very professional and quick with getting the job done. I plan on using them in the future.


Salesman showed up on time. Provided an estimate via email as promised. Workers showed up on time and did a quick and clean job. Overall a very good experience.


They were extremely pleasant, careful and worked quickly. Pleasure to have them work here.


Jay was extremely professional, friendly, and prompt. He also made me feel at ease as a first time home buyer and was very detail oriented with the services I needed for the insulation in my attic. He really helped me understand the difference between laying insulation versus blowing insulation. I feel very thankful to have found Jay and I would highly recommend this company to anyone I know. In fact, I think next door neighbor is going to use their services as well.
