"My consultation with Stellar was scheduled within a day, met with Patrick on 5/1/25. Time was taken to understand the process, everything that is involved and what my options were. Time was taken to listen to what we wanted/didn’t want and thorough explanation given of the entire process. On 5/2/25 Stellar contracting called to review details and confirm our choices. On 5/5/25 Stellar scheduling called and full installation scheduled for 5/9/25, completed 1 day! The crew and project manager, Cisco, were fabulous to deal with on the install day and even after. A link was provided where we could see pictures of the whole project as it happened. Cisco was readily available on install day and even after with questions and concerns. It was obvious that Cisco did care about the roof we were getting and took pride in the quality of the job that was done. The crew paid good attention to the clean up, there was a lot of debris all over the place. Looking forward to future business with them!"

"I had my walls done in 2024. I ended up removing one wall for a remodel and found the wall had limited insulation from USA Insulation. I called them and they came out and look at it and did a thermal image. They said that a wire mess in the one room caused the wall to not be filled. They should have known there was an issue. I questioned the rest of the house and they said the thermal image showed no heat loss. I doubted them and they said they could drill holes in every room. I drilled three holes on the outside of my living room. One showed insulation but did not fill the cavity. The other two did not show any insulation that the thermal image did not catch. They offered me $250 for the one room. They have not responded to 2 emails and 2 phone calls after I found issues in the living room. They said they would make it right and told the BBB they would make it right and I have not heard from them for 3 months."

"Glen arrived at my house promptly. He was personable, friendly, professional and very thorough. I originally was interested in having insulation blown in to the exterior walls. Glen evaluated my home. He and recommended that I concentrate on insulating the upper area of my home, as I no longer had any insulation in that area. The other contractors that came to my home never said anything about my existing issues, they just quoted a price for the blown in insulation. So I knew Glen was the person for the job. He identified my immediate need. I highly recommend Glen and his crew for your insulation needs. Thanks Glen."

we like to do estimates on Saturday but we will do are best to accommodate everyone's schedule

"We hired Angelo's spray foam and Russ a terrible job installing the spray foam you missed spots throughout the ceiling everywhere. We sent him pictures showing him spots he missed and spots that weren't as thick as what we paid for. He agreed that the quality of work was terrible and said he would come and fix it. After 12 weeks of not showing up and making up excuses of why he can't get here, he eventually told us he's not going to fix it. My wife and I filed a lawsuit against him. Too tired to redeem our money to pay another company to come and fix his work. Would not recommend this company"

Insulation questions, answered by experts

Yes, products made from renewable resources and with reduced chemical impacts.

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

Each insulation type has its own R-value, so you’ll want to weigh the pros and cons of your materials when deciding which one will give you the best value. Energy.gov recommends you choose a pipe wrap that’s at least one inch thick. The International Code Council (ICC) suggests choosing a pipe material with an R-value of at least 3.
