We greatly appreciated the work of David and Scott in installing 35 new windows at our house. They are both very hard workers and the quality of their work was excellent. They became almost a part of our family in the five days to do this big job. We are extremely happy with the windows installed and the work of David and Scott.

CRS Exteriors did a great job with our 1955 home basement window replacement. They were easy to work with from start to finish and didn’t pressure us to buy (unlike other window companies in the Knox area). On the day of installation, John Horne installed all 3 windows by himself and did a fantastic job. They look better than I expected, despite two of the windows being placed in a cinder block wall with extensive damage due to movement and cracking over the years.

I purchased 13 windows and a sliding glass replacement door from CRS last fall. The whole process was easy and their team is great. Ed, the salesman was good and there was no pressure from him to buy anything and he just stated the facts. For a salesman, Ed was very knowledgeable about the products they sold, which is very rare these days in sales. The install teams did a great job and were professional. Corey and Karl put in some long hours removing all the old windows and door from my old house. It's amazing how good everything looks now. They even filled out the paperwork for a TVA energy rebate for me. Highly recommend them for any replacement windows or doors you may need!

Dave and Scotty replaced our windows with skill, knowledge, and accuracy. They cleaned up immaculately after each window. They went above and beyond in taking down shutters and blinds and then putting them back up again. I’m super pleased and excited about the quality and beauty of our new windows! Dave and Scotty replaced all of our exterior doors, except the front door (more later), and once again, went above and beyond. They reconnected our alarm system with each door replacement and repaired an area where bees had made a nest in the wall. They made sure I was satisfied with each door, every day. The front door did not fit and the owner came to house, assumed full responsibility, and they are currently working on a solution to the problem. I am trusting it will be handled in the professional manner I am accustomed to with CRS. I appreciate Dave and Scotty's years of experience and attention to detail.

James came out in September, after a few exchanges with other window installers. We decided, we liked the Infinity by Marvin the best. Windows were custom built.They arrived at the shop, near the end of the year. We scheduled an installation date. John Horne and his helper showed up, and got half of the windows installed on the first day. Four windows. It is a pretty small job, eight windows total. They returned after the New Year, and installed the rest. They did a pretty good job, of keeping the mess down, and cleaning up, after themselves. They had a few issues, that needed addressed, not the installers fault. All issues have been addressed. Got to give a shout out to Frank, back at the office. Always so nice, I can be a bit, naggy. We are very happy, with our new windows. Have gotten several compliments on how good they look. Lifetime warranty. I'm sure if I ever have a problem, They will take care of it. Edit add on .These guys are great! I highly recommend.

The new entry door that CRS installed for me looks amazing. The installers, Karl and Kurtis, were highly professional, and did the job quickly and proficiently. If you need a new door, call CRS Exteriors.

We had 20 Marvin Infinity windows installed. The Father/Son team, Ray and David Cox were our installers. They arrived the scheduled date on time with a trailer full of our windows. We had a brief introduction. They checked out the job site, and what was involved. Then they started staging windows. They both told me to watch all I want and ask all the questions I want. They both are true craftsmen and have been doing this a long time. What more could we ask for, you might ask? Well, here it is…their attention to detail is absolutely “spot on”. The teamwork between these 2 guys is awesome! For the most part they work separately, occasionally they come together to help each other, then back apart working on something different to contribute to a very smooth process. Just like a “well oiled” machine. Before leaving for the day… they both walk through the job site checking things, picking up trash and making a plan for tomorrow. They won’t even let the smallest questionable item pass by unnoticed. They are both very friendly and kind, and during this project they both have become our friends. They respected our home and treated it just like it was their own. And now… to the Marvin Infinity windows… They are very high quality, and they look much better than we initially imagined. This is the drooling time. We will be showing our new windows to everyone that comes into our home. Someone told me once that the window installation is half of the window quality. Now I am a true believer. Our windows were installed by professionals with tons of experience. Thank you to Ray and David Cox for a job well done and to CRS Exteriors for the sale and management of the project. Alan was our sales rep. He provided us all the information we needed to make the right choice on which window we wanted. Ralph made the accurate measurements to order the windows. He is very knowledgeable in construction and repair of windows. I honestly believe that Ralph has forgotten more about windows than I will ever know. And last but certainly not least… Frank. I never met him in person, we talked a lot on the phone. In my mind, Frank is the “go to” guy. He has coordinated and scheduled our window installation when it was most convenient for us. He also has answered a ton of questions along the way. In conclusion, CRS Exteriors is a top-notch company that has a great reputation, with highly skilled craftsmen. I will be back for any future projects that I might need that are in your job scope and would recommend CRS Exteriors to anyone looking for high quality work. Thank you, to you all!

Ed and the whole CRS Exterior team were great! We had an easy experience and we love our new windows! Highly recommend. Updated review! Went back for a new front door. It wasn’t an easy install and Karl and Kurt did a fantastic job! Love the new front door!

Cory with CRS came out and installed our windows yesterday and did an excellent job. We needed three new Marvin windows in our condo. Being a remodel and not new construction with similar looking units surrounding us, he took the time and effort to explain the entire process and how the finished product/result would look. Throughout the job he would stop and make sure I was happy with the progress and wanted to know if I had any additional questions. When the job was done he made sure I was 100% satisfied and cleaned up the entire job site. If we have any additional need for CRS to come out we will specifically request for Cory to be the person on the job.
