"River Valley and there crews(Anthony, Nate, Jason, Dayne, Matt, Cole, Paul, Robert, and Billy) did a great job. Their installers were respectful, friendly, and hard working. Work was done in a timely manner and done very well. Working on an old house brought some challenges which were addressed effectively."

"I was very impressed with Sentri Homes - their customer service was excellent. They sent a subcontractor to install some vinyl laminate in my bathroom and he ended up getting glue all over the carpet in our bedroom. The sub ended up ghosting both me and Sentri, leaving me stuck with a ruined carpet. Sentri stuck with me for over a month to get the carpet replaced with the identical original and to get the vinyl job 100% completed. The carpet was a Home Depot exclusive and Sentri handled everything with them. I will be using Sentri for a much bigger renovation I have coming up soon, because I know that they will make sure everything gets done right no matter what problems come up. The vinyl looks great too."

"In 2017, when I was looking to purchase a house in the Rockford area that was needing a full siding install I contacted GF Company in Belvidere. IL, who I found on Angie’s list and at that time GF Co had great reviews. Strangely enough these great reviews are no longer to be found on Angie’s List. It should also be noted there is a GF Siding in Cherry Valley. IL, this is Not the company that I did business with. Ariel Zmijewski (the owner) got me a quote quickly and I decided to purchase the house. A few months later in July 2017, I contacted Ariel again to discuss the finer points of the quote, the price was revised slightly and the Ariel mentioned that once a deposit was paid work could start 6-8 weeks later, but said the install would be finished before the cold weather arrived. I started creating a color layout and Ariel provided some feedback on what would work and not work. To this point I was very happy with progress. In September 2017 I paid a deposit of over $8k (about 44% of final price) and awaited updates for a start date. Nothing happened. In early March 2018 I contacted GF Co by phone stating that I had been very patient and they had had $8k as a deposit for the last 6 months and I had nothing to show for it. After a couple more calls and emails Ariel showed up with his foreman Mark and they said that work would start in the middle of the following week. Much to my surprise the work started on time. Over the course of the next 4 weeks Mark and his crew worked hard, only missing a few days due to bad weather, I even agreed to having some extra work done by the team, some wooden entrance steps that needed replacing for an additional $2.5k. By early May 2018 the job was finished the house looked great and I was very happy with the work and appearance and was getting compliments from neighbors too. The balance of owed of over $10k was paid with 48 hours of the work being finished. Again I was happy with work done, until… A few months after the install a TV cable box started having troubles. Cut a long story short the wall socket died because cable was suddenly defective, also the crew had moved the exterior cable input box and this didn’t help the issue. Comcast fixed it, but I now have an exterior cable showing and they had to drill through the siding. Then around Halloween 2018, less than six months after having the install completed, I noticed that a piece of siding (6ft approx.) had become detached underneath a window, trying to pop it back into place did not resolve the issue. After checking all the other exterior windows I noticed 1 other window was about to do the same thing. I called the GF Company main number and left a message with the receptionist for Ariel to contact me. No response. I called again a couple of times and left more messages still no response. In March 2019 siding problem under windows still Not fixed, I called GF Company again, no answer, and no voice mail. I called a couple more times on different days still no answer or voice mail. I then sent an email to the company and to my surprise I received a response from Ariel stating this was the first that he had heard of it. About a week later (3/26/19) he showed up at my house to view the problem. Ariel stated that he would get someone over to fix the problem, but would not give me a date or time. On 4/2/19 I emailed Ariel again asking for confirmation of a repair date ? Nothing but crickets… On 4/30/19, I sent another email to Ariel requesting that the repairs be completed before the end of May 2019, again no response. Quote / contract says: Customers will receive a Lifetime Warranty on Material and Workmanship Reported GF Company to Illinois BBB on 6/5/19."

"Very quick work, they called to ask if they could come a DAY EARLIER and within an hour all the work was done and the area was spotless."

"Everything went well. Workers were professional and they got the job done in a timely manner. Would definitely hire again!"

"Very professional sales and service. Would highly recommend to anyone in need of their services"

"The windows our great! Energy saving due to the insulated glass saves money and never fogs or has condensation on the windows. The durability and ease of cleaning and opening these windows are a dream! Along with the aesthetics.
The crew that came to install the windows did awesome work fast cleaned up there work area things were in great shape when leaving. Since then I have had follow up calls and follow visits to make sure everything is working as I believe it should be which it is. Great company!! Would have them do any work for me and my family and would have them do anyone else's work too. Do not let this company slip by without a try!"

"This company provided the cheapest estimate for the services I needed. They came out right away and were very clean and neat. They showed up when they said they would and got everything done quickly. Overall they were great all around to work with and I would highly recommend them. I am a realtor and I refer them as needed to my clients."

"Have you not done the job yet, It has only been 5 weeks, and they ordered the wrong siding."
