On 4/30/2025 Brian Graham had this to say:
Benny and his team went above and beyond to help me with a massive attic problem I had. I bought my first home last year and calling it a "fixer upper" would be generous... It was a hoarders home. I was able to do most of the clean up myself, but the attic had thousands of pounds of junk. Amongst the junk, there was multiple dead raccoons and hundreds of pounds of feces. It took me weeks to find anyone who would even consider helping. And the quotes I received cost more than my car. Illinois Insulators was recommended by a friend of mine. Benny came by to take a look and without skipping a beat said no problem we got this. All for an incredibly reasonable price. Benny and his team cleaned everything out, sanitized the space, and reinsulated it all within a single day. It blew my mind. On top of that, his team saved anything from the attic they thought was cool or might have value for me to see when I got home. PLEASE NOTE: Some of the negative reviews I've seen posted here have nothing to do with the type of work that the Illinois Insulators team perform. I work in the HVAC and Plumbing industries and I've seen these problems time and time again. A leaking or burst pipe in your attic space is a plumbing related issue that would need to be addressed by a professional plumber. As for the condensation issues, if you plan to use insulations like Cellulose or Fiberglass, a basic attic fan will help exhaust the space properly to help remove moisture and condensation. This is listed on their website as the types of services they provide. However, if you are using spray foam to insulate your house or attic, YOU NEED TO CONSULT AN HVAC TECHNICIAN!!! Spray foam is very effective for insulating a home, but it also creates an air tight seal that does not allow any airflow, which will result in a buildup of condensation and mold. A basic attic fan will not be enough to accommodate this type of application. You will most likely need to install an ERV (energy recovery ventilator) that will help circulate air within the space that you've sealed with spray foam. Since the work Benny and his team did for me, I've received multiple compliments from other contractors and pest control companies saying how nice and clean my attic is. Illinois Insulators were incredible to work with and I would highly recommend them to anyone. THANK YOU GUYS SO MUCH!
