Best insulation pros near Ontario, CA

"Everguard Home Insulation was excellent from start to finish. They provided a competitive quote and followed through with timely, efficient, quality work installing attic insulation. Highly recommend for your next home improvement project"

"In July 2024 I hired Insulation Labs to add more insulation to our attic. They showed up on time with a truck full of insulation, and a few hours later they had put all of it inside our attic. They did a good job up there. I am very pleased with how everything turned out. One thing that distinguished Insulation Labs from some other outfits is that they did not try to up-sell us with services we didnâ t need."

"I love the insulation. My room has no insulation at all. Every time I entered the room after coming from work, it was like walking in an oven. With the insulation, my room now is cool in the afternoon. The price Pro Insulation, Inc. charged is reasonable. I just love it. It is a good investment."

"Jesus and his crew at Next Level Insulation completed my attic needs (Insulation & cleaning) flawlessly. They are true professionals! Jesus was very responsive in keeping appointments, providing a quote and completing the job. He explained the job they were preforming and kept me informed every step of the way. I truly recommend Next Level Insulation."

"Alpha insulation is a good choice. Their installation was great. The guys cleaned up all their mess. Which is a plus for me. Miguel was easy to talk to. I told him what I wanted done to my house and he gave me a great price for what I asked for. So I hired him. I would recommend alpha insulation to friends and family."

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"After having a new air conditioning system installed, to replace an old inefficient one, we decided to make sure our attic had the correct insulation as well as the appropriate R-value. Since our home was built in the 1950's, the insulation throughout the attic was minimal. We hired Insulation Commandos to survey and provide us with the appropriate solution. The solution involved removal of the old insulation, cleaning the area, and installing the correct insulation based on our homes location. We now believe we can keep our energy costs down and provide less strain on our AC system. Great job team!"

"This business is great to work with! They showed up early and got right to work. They laid down protective plastic as we have blown insulation that gets everywhere. They installed attic and subfloor. I thought they would be here all day. They were down in about 3 hours. Quality work, professional and very informative and clean!"

"I couldn't be happier with the experience I had with this company. From start to finish, they were extremely professional, honest, courteous, and respectful of our home. They did an excellent job blowing insulation into our attic, and they made sure to keep everything clean and tidy throughout the entire process. What I especially appreciated was dealing with a family-owned business consisting of a father and his two sons. It's refreshing to see a family take such pride in their work and treat their customers with honesty and respect. Their pricing was also very reasonable, especially considering the quality of their work. It's not often you find a company that checks all the boxes: great workmanship, fair pricing, professionalism, and integrity. I would highly recommend them to anyone looking to have insulation work done. They definitely earned my five-star review!"

"Attic construction installed a hybrid of batt insulation and blown in (corners that were hard to install batt in) after cleaning and sanitizing the area. They sealed all potential entry points for rodents. The workers showed up on time in the morning, were friendly, and the 3-man team was well coordinated in completing the tasks, including a post-clean up. They worked all day and the job was completed to my satisfaction. I would highly recommend them, they know what they are doing and all workers having completed a training program at Owens-Corning (which is the only product they use)."
