Tom is extremely generous with his time and willing to help in any way he can! Highly recommend.

Tom is knowledgable, and responsive. He takes the time to listen to your needs and explain not only what his service will provide, but other considerations for your project. His working crew were personable, professional and efficient. They explained their process and what to expect, did the work quickly, and left the work space tidy. I have already experienced less heat loss within the home during a period that I shut off my HVAC system with cold temps outdoors.

Provided great response and good advice.

I don't write negative reviews easily.

Not only did I find his years of experie

Tom came to the house promptly to address my issue with pipes freezing. He is extremely knowledgeable and patiently explained the options and provided helpful pointers. A no pressure process, I never felt like he was trying to upsell me.

I couldn’t be happier with Chicago Green Insulation. I had a unique project, and got several quotes. Tom got the job not because he was cheapest, (which he was) but because he understood my needs and came up with a unique approach that saved time and money. I didn’t get a cheap job, I got a great job, done for less money because of Tom’s expertise.
