Aaron is a true professional who makes sure the job is done right. I've used Aaron and his team several times and it was a home run each time!!

Service and attention to detail was second to none!

The owners and workers are professional and the best at what they do. We will definitely be working with THI again.

The crew was hard working, polite & very detailed. They completed the project in a timely manner & we are thoroughly pleased.

Our house looks amazing and they exceeded our expectations. THI has a showroom in Grayslake where we went to pick out our cabinets, counter tops, and paint which was extremely helpful.

They were very professional, prompt and efficient while completing our project on time and within our budget.

Our place went from old and outdated to modern and fresh. In the end we were very satisfied customers.

Aaron and his crew were phenomenal in all aspects of our new home remodeling. THI did a beautiful and speedy job with our custom fireplace, powder room remodel, trim work, hardware, and other misc. handy-man repairs.

Aaron is wonderful to work with. He's so efficient and can handle anything you throw at him!

Everything done is top notch at fair prices. I recommend 100%.
