"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!"

"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."

Angelo's Southern Tier Spray Foam
Angelo's Southern Tier Spray Foam
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"
