We were referred to John for full window replacement in our 1940s home and are thrilled with the outcome. Our original windows (picture 1) were installed when the home was built and in bad shape and no longer helped insulate the house, so we opted for full window repair, including trim and casing. John was a great at listening to our desires and guiding us through options. We went with the Marvin Elevate series (painted pine), installing 10 double hung windows across our home, which took less t

We had the roof, skylights, gutters, soffits and fascia replaced. Our contact at the company, John, was very knowledgeable from the first time he came out to give us a quote. My husband specifically wanted a ridge vent across the entire length of the roof and we had a situation at the corner of the house that required a bit of ingenuity with the gutter.

Berg was fantastic start to finish in replacing our roof and gutters. Nick was a pleasure to work with. The quote was quick, precise, and very reasonable. He’s incredibly responsive, even at odd times of the day and weekends. He answered all my questions in detail. The work was high quality and efficient. I highly recommend Berg for your home improvement needs!

Berg Home Improvement did an excellent job from start to finish. The price was very reasonable and the quality of work is top notch. Our project manager, Nick was so professional and friendly. He kept us informed every step of the way. We received a quote promptly and work started within the proposed timeline. Nick came to our home both days the work was being completed to check in on things. The workers were so respectful of our property and kept it impeccable. Not a single stray nail to be fou

Just a quick review to express sincere gratitude with the way Berg completed our recent roof and siding replacement. Our project manager, John Oros, was very professional and knowledgeable. In addition, communication was always timely and proactive. We first did the roof and then John came out to help us replace cedar siding. He helped bring out samples of siding and sent us pictures of projects with colours, they have completed in past. Thanks for the positive experience and will call Be

I'll start off by saying the communication between the salesperson and myself was top notch starting from initial quote all the way through the install of a sloped roof, flat roof, gutters, downspouts, fascia and capping. The issue I still have is Berg Roofing does not follow residential building codes in the city of Naperville when it comes to flat roof installations as evidenced in the photos attached. All roofs including flat ones require a drip edge to be installed. Berg took the shortcut
