Testimonials
What Our Clients Say About Us
They did an amazing job on the ceiling in my garage, the previous temps were 135-140 degrees after the sun beat on the roof. Now the same spot is in the 90s! Much more manageable in the garage, and my mini split does a better job keeping up!
Jeff did an amazing job at an amazing price on our new construction home. Showed up on time and was very professional and personable to work with. He paid very close attention to detail for all the spray areas and ensured that everything was covered and protected before beginning work. Jeff and Michael did the batt insulation in my basement and spent the time to custom cut all pieces to ensure a tight barrier. I only gave them 5 stars because I can't give them 6.
True Seal did an amazing job insulating our home. We would definitely use them again. Highly recommend!
