What Our Customers Have To Say

  • We used Jimmy Williams at Specialty Insulation. He’s been wonderful to deal with, and his company did a great job… identified potential rodent access points for no charge. He made an aggressive bid for the work and delivered on everything.Barry Rakowski


    I used SI for two jobs on my recently purchased home. Jimmy and his crew were professional… I felt the immediate impact of the new insulation in the seal, temperature and sound… I also noticed they use quality products. Great job and I highly recommend.Louis S.


  • This company is top notch. They helped me with attic insulation, rodent proofing and a moisture barrier for my home. I had a great experience with Specialty Insulation because the owner was on site and very professional. I highly recommend this company to all. Dr. Ben Baker
