We are the most inexpensive roofing company in town. That doesn’t mean we cut corners and leave you with a bad roof.

Finally -- an exterior company that actually knows what customer service is! I had a small gutter project that no one would even call me back about. Muller (Rob) called me back immediately and got the job done asap. Because of this, i have an enormous amount of additional exterior work that needs to be done on the house and Muller will absolutely get my business. Amazing that there are firms like Muller still left in the world. No hesitation recommending Muller to anyone.

I have hired Muller Exteriors for multiple projects on my home over the past 6 years. The work included the following: new roof, roof maintenance, new doors, new windows, & attic vents. I have found them easy to work with, prompt, efficient, and professional. They are accommodating, neat & pleasant.
We had a bad leak in our roof that rotted out a window and a big patch of drywall in our kitchen ceiling. We had several roofers come out to look at it, but nobody wanted to do a full inspection or even get on the roof. Then, we called Muller Exteriors in Lake Zurich. Dave Muller came to our home, did a full inspection, came up with a detailed, sensible plan, talked to our insurance agent, and went to work. Mullers Exteriors team was hard-working, very knowledgeable, punctual and polite. I have to admit that working with us was not super easy because the roof leak had caused a lot of damage. But, the Muller team walked us through everything calmly and patiently and answered all of our questions. I highly recommend Muller Exteriors in Lake Zurich. You'll get great work at a fair price by a knowledgeable and dedicated team.
I'm so happy that we hired Muller for our job. Adam our installer was professional, courteous, and excellent at his craft. The quality of his work is just outstanding!

I had our patio door replaced today by Rob and his crew. They were here on time and did a very professional job. The door quality is excellent and at a very fair price. Rob has been very informative and helpful from the very beginning until the end of the job. I would highly recommend this contractor. The next hailstorm, I have David from Muller Exteriors on my speed dial!!! Thanks again guys

We were recommended to Muller Exteriors from professionals in the trade that said our particular roof (specialized exterior roof insulation panels) was not something they could take on. We received a fair quote from David and he worked within our budget. The entire Muller team was outstanding. They were very professional and I was confident in their work. They really know what they are doing. The team put in some long days in extreme heat and got the job done on time--just as promised. We are very happy with the new roof, the foam insulation, skylights, gutters and fascia. Great job guys and we will see you again when we are ready for the other roofing project!

New gutters, roof, siding all done by Muller. They are an awesome company to work with. Price was very fair and work was coordinated to match our demanding schedule. I would strongly recommend Dave and his company to all my friends and family. On a extra note his employees were very polite and concerned. I especially appreciated that Dave took the time to check on his work and come personally to our home to assure my wife was happy. Great job!

Based on a recommendation, I reached out to Muller Exteriors to evaluate and possibly replace our cedar shake roof. Our experience has been outstanding! Dave Muller conducted a comprehensive analysis of possible roof damage and assisted in convincing our insurer to fully cover replacement of the roof. He offered excellent advice and helped us select the proper materials. His installers were thorough and meticulous. Although we were unable to be at the house while the work was being done, Dave kept us up to date of their progress with pictures and regularly communicating with us. It is obvious Muller Exteriors is truly a customer centric business, professionally run with care and attention to details. I highly recommend Muller Exteriors!
