Services We Offer

Air barriers

Our air barrier systems help to enhance structural durability and boost indoor comfort and air quality.


For your home or commercial building, we install 3 types of insulation to ensure you have the right solution to protect against cold in winter and excess heat in summer.

Acoustical insulation

We can help control bothersome noise. Our insulation is designed to diminish the noise from room to room and from inside a building to outside and vice versa.


We provide structural and foundation waterproofing, above and below-grade, which is an important component of any commercial building structure.

Cavity fill injection foam

We ensure that commercial buildings with little or no insulation are properly insulated by injecting foam into all empty cavities.

Intumescent & thermal barrier fire coatings

We are experts in understanding the particular code requirements for both residential and commercial buildings and can recommend the best combination of foam and coating and can provide you with the best recommendation for additional fire protection.

I had a great experience with Superior. They showed up when they said they would show up, communication was easy, clean work. 10/10 would use them again and recommend them to others. .

Let me tell you, if you're in the market for spray foam, don't waste your time with the 6 other companies in the area trying to outbid each other for the same project. They all use the same machines, they all use the same foam. Not only is Superior Insealators the most affordable; they are professional, courteous, and have a no-pressure sales pitch. They are down to earth when they come out to quote you and don't add on costs like "clean up" or "prep" like the other companies do. When the guys came out to do my garage, they did a phenomenal job. They made sure to cover up everything in my garage to prevent backspray. They took their time and their work was outstanding. I can't say enough about this company. Their other reviews do not lie. Juan and the rest of the crew there are phenomenal with customer service and honesty. Something you never find nowadays. If you're in the market for insulation, this company does everything the RIGHT way and does not play game like the competitors.

100% Satisfied! 30x60 pole barn with 5-6" of open cell on the ceiling and 1.5" closed cell on the exterior walls. Excellent value for the money and were much cheaper than what others have quoted. They were more than willing to work around my schedule and would highly recommend this company to others.

Built a new house, but builders did not insulate crawl space. We contacted Superior Insealators and Matt our estimator e out and was ON TIME. He was very professional but very easy to talk with and work with. We initially just had them do the walls of the crawl space, What a difference it made. Then we made the decision to see what doing the floor joist. Again we called and Matt came out and gave us the bid. We accepted. The team was very professional both time, made sure they we respectable of our new house and cleaned up very well. Everything was a wonderful process
