“Our relationship with Mainstream began 4 years ago. We purchased a home that needed a lot of improvements. First the roof, windows, and doors. Second came the gutters and more windows. This last project for the siding was the icing on the cake. WOW!! Our 50 year old home, looks like new construction. The new look of our home is not the only surprise we have had. Our energy savings has been fantastic. We noticed a big improvement when the windows and doors were installed. Now that our Fullback Thermo Support System siding is in place, I know our gas bill will be even lower. I praise the Mainstream Team to everyone. Marci and the guys are wonderful to work with. Each crew that has come to our home has shown professionalism and respect for our property. The work has been done in a timely matter, and no debris left behind. No need to shop around, Mainstream is #1 with us. Thanks for the great work over the past 4 years.” - Jamie & Laura Smith, Moline, IL

"Our experience with Mainstream was excellent! The quality of the work done has been excellent from the roof to the windows and the siding….the house looks great! It’s like a new home! The workers were extremely friendly and professional. Steve, our salesman made all the difference in choosing Mainstream. He followed up constantly from the sale to the end of the work and in between. Without his superior presentation, we had planned on going with another company due to a friend’s referral. All in all, a great experience.” - John & Teresa Pagan, Bettendorf, IA

“Several things I appreciated; timely fashion of installation with professionalism, thank you for complete clean up every day, accountability of your service with good communications. This all started at the beginning of the contract until the end of the final inspection. Special thanks to Marci with her daily phone call, and to all your participating employees including Jeff and Dave. Good Job!” - Joan Lehan, Rock Island, IL

“We could not be happier with our new windows and door! Each member of your company that we have worked with has been very kind and put our satisfaction as a top priority. Our windows look beautiful. We appreciate your friendliness and the follow-ups after the work was done to ensure we were satisfied. We will definitely recommend your company to our friends and will use you for home improvement projects in the future! Thank you” - Tim & Tracy Wren, Davenport, IA

“We are very skeptical people, so when we went through the process of getting estimates for work we wanted to have done to our home. WE went through several different contractors really not happy with any of them. So, I finally called Mainstream, and we are so glad we did! From the very first meeting, to the actual work being done, to the final victory lap. The people that did the work, and the quality of the materials, and the great feeling they gave me. They talk a lot about how much they care for their customers, and that is for REAL!!!! Thanks for a great job well done! WE will definitely call Mainstream for any future home improvements!” - Dale & Kathy Schutters, Moline, IL

To the staff of Mainstream Home Improvement: “The journey of deciding, shopping, and installing new windows became a desperate desire to get to the end. However, during the shopping tour I came upon the first key person of Mainstream Home Improvement. As with the other companies, the process was on track. But, I became aware that I was learning about some very special windows through a presentation that did not speak down on any other company or their product. The day of installation arrived, but so did the worst kind of weather. Four expert and brave window installers, started in the living room and kitchen, but after 4 hours of pouring rain driven by high winds they gave up. Taking out the windows leaves the house open to possible damage due to weather. The weather was better the next 2 days and the windows and 2 doors were completely installed. The young men were so very polite, quiet talking and went about their business very efficiently. The neatness was extraordinary. The end result is windows that look wonderful, allow for a very quiet interior and are cost effective for any kind of weather. There are no words big enough to say thanks to the hardworking individuals working for Mainstream Home Improvement. I would recommend to all who ask that there is no other company in the Quad Cities better qualified. Thanks you all for an outstanding job well done.” –Louise Wilson, Moline, IL.

“Hi Jeff & Staff: We just want to take a few minutes of your time to let you know how things went. First would like to say how pleasant it was when we first met Jeff at the home improvement show. Talking with him that short time made us feel like we knew Jeff for a long time. We set up an appointment with him to give us an estimate for siding on our home. When he completed the survey of the house he came in and sat down and went over everything. Brenda liked the way he conducted himself, not only as a professional, but also as a person. Jeff even took the time to make small talk with our 4-year-old daughter, Alexis, and answer her question. This made our daughter feel like she was part of the project.

We like the way your staff called every night to check and see how things went that day. Your staff was always willing to listen to what we had to say and then act on the opportunity when it came up. This alone deserves and “A”.

The crew that was here during the siding installation was very professional. When there was an opportunity we were able to talk with them about any problems and work together with them to get any issues at hand solved and then move on with no hard feelings. This all made for a good working relationship.

In closing we would like to say that we are glad that Mainstream Home Improvement helped us out. Mainstream made this job very easy and worry free. I would highly recommend that if you have any home improvement projects that you would really consider Mainstream, they treat you like family.” – Wes & Brenda Ehlers, Bryant, Ia
