Insulation Installation or Upgrade

I asked three different insulation companies for an estimate. After speaking with Miquan from Johnson's Insulation, I felt very comfortable with him because he provided reasonable answers to my questions. He did not try to oversell anything and he was very polite. I was provided with a quick response when I asked for the quote, and I was able to schedule very soon afterwards. His crew came out and they did exactly what they said they would do. They removed the old blown in insulation, cleaned the attic and sealed it, installed new insulation and a radiant barrier. The radiant barrier really did the job. My house is much cooler now. The quality of the work they do is outstanding. They even showed me pictures of my attic after the installation, and I am very satisfied. Thanks Miquan, I am a very happy customer.

Johnson's insulation offered a great package. While it wasn't the cheapest it had all the things we needed done to our attic. Their equipment was top notch - very powerful vacuum. Experienced and trustworthy crew. The whole job happened smoothly, no hiccups. Highly recommend! Thanks Miquan for patiently answering many of my questions and helping us through the whole process!

I received a few quotes to insulate my home that I just bought. Miquan did a thorough assessment of my house and we found out that my attic was already insulated and he said the insulation was done nicely. That right there made me feel at ease since I knew he was being honest and not trying to charge me to do work that wasn’t needed. Ended up going with the drill and fill on the exterior walls of my home (from the interior). He even insulated the ceiling on the garage converted family room. I am SO HAPPY I chose them. Not to mention they came in under budget and was the least expensive of the other estimates. Thank you so much to everyone at Johnson’s Insulation!

They did a good job of adding blown insulation to the attic. They covered all entry ways for rodents. The work was done in a timely manner.

Johnson's did a great job installing 2244 sqft of Knauff insulation. I like their stress on being eco-friendly and using such products. However, that message is slightly at odds with the fact that they used a gas powered vaccuum (used to remove existing insulation), and it spewed a lot of smoke throughout the day in our backyard. I was not comfortable with that at all. Update: Miquan messaged me that there is no electric vaccuum in the market, so I'll add that one star back. Great company!
