John Gallagher is extremely knowledgeable, regarding his industry. He has a ton of product samples and knows his products. He took the time to educate my wife and I and we ended up getting our entire house done with custom Marvin windows and the best vertical vinyl insulated siding available (which I had no idea even existed). Other companies quoted our job but EDI had the best plan for our home. On a side note, every person that did work at our house was a CRAFTSMAN and did exceptional work. The work was done as scheduled and exceeded our expectations. THANK YOU JOHN!

Had my siding down with EDI and they got the job done in 2 weeks when they promised me 3 weeks. They are fast and professional & do the best work in Naperville.

The owner came to my house himself. He carefully assisted me in selecting the right product/colors etc. ..We are sooo pleased we chose EDI for our home.
