Testimonials

On 4/3/2026 John B. had this to say:
Shawn did an exceptional full attic/energy evaluation in order to find why our home was having a difficult time maintaining heat. He offered multiple solutions. He was knowledgeable, had great communication and handled everything (from insulation to HVAC) to get our home as efficient as possible. Shawn and his crew went above and beyond; they are very hard working, honest, clean and showed pictures to explain all the areas that needed attention. It's rare to find a company that is this detail orientated. Would highly recommend Shawn and his crew to anyone looking to improve their home's efficiency.

On 4/2/2026 Stacey Ricchiuto had this to say:
Shawn and his crew have gone above and beyond multiple times and they absolutely deserve the recognition. We have used them more than once and every experience has been just as impressive as the first. They are thorough and make sure everything is done right. Shawn and his crew deliver the same high level of service every time. Always on time, professional and respectful of the space. You can tell they take pride in what they do. If you want a company you can trust not just once, but over and over again, I highly recommend Saunders Insulation. You won't be disappointed! Testimonial written by Stacey Ricchiuto on this site.

On 12/31/2025 John Ellis had this to say:
We requested an inspection and quote for Saunders Insulation to correct the improperly installed insulation under our heated sunroom at our residence in Galena, IL. They gave us an estimate and proposal that we accepted and the work was completed in good order.

On 12/10/2025 B Meyers had this to say:
Our insulation was matted down, inefficient, and very old. We had saunders come and take the old and blown in new. They sealed all the air gaps and installed new. It was an instant improvement, we noticed day one. The crew arrived early and got right to work. Very friendly and professional. We will use saunders for anything related in the future!

On 10/20/2025 Heather Hermes had this to say:
We had Saunders Insulation come out and spray foam our attic in our 1908 farm house. Shawn was great to work with, he was personal and professional. We have noticed a huge difference in not only the heating and cooling value of our home. We noticed a significant drop in the amount of bugs we use to get inside our home. We would highly recommend them to anyone. The price was fair and we feel like it was well worth it!! Thank you Shawn and Team!!
