Overview
About Us
Bill Kesterke started Key Exteriors in 2003 for one reason: Integrity. Having worked in the business for a large national company with little control over the finished product, Bill was determined to start a company that focused on providing customers with the highest quality products, installation, and service after the sale in the industry. Bill’s goal was not to be the cheapest nor to be the most expensive, but simply to be the best value bar none. He also wanted the complete control over installations that only comes from ownership. You have Bill’s word that Key Exteriors will offer you only the best. If it’s not right, we’ll make it so, and you can count on that!

Customer Reviews

"Overall, we are pleased with the work done by Key Exteriors. They replaced all siding, shutters, and 6 windows. There was a bit of a delay from the expected start time until when the project started (expected November 2022, started late February completed May 2023) but I don’t know that Key could have moved any faster with supply and labor being what they are currently. The siding crew was very good, and the window crew was excellent. Both crews were highly communicative, and they did a great job of cleaning the work site. I would recommend them to others, and we have them coming back to quote additional work."
"This 5 Star review is more for Rich our salesman and Dan and his installation crew. We started our window process with Rich back in May of 2022. We were told that someone would reach out within the week to schedule the initial measurement of our windows. This was our first delay. No one contacted us for two weeks. I contacted the main office and no one reached back out to schedule. I contacted Rich, then the same day we had a date scheduled for someone to come out to measure for our windows to get the process started. Our windows finally came in on November 14. We were told that someone would be in contact with us shortly to install our windows! 4 weeks past and we did not hear anything from Key Exteriors. I emailed the office to see when we would be contacted. I was told someone would be in contact with us shortly. We did not receive any further communication until I got Rich back involved on December 27th. That is 6 weeks after our windows had been in at Key Exteriors. Bill the owner told us that we were scheduled two weeks before Christmas but weather kept them from coming out to our house, and then the Holidays. We never received any communication that we were even on the schedule before Christmas or that we had been "canceled". The conversation with Bill continued with us getting on the schedule for January 4th. We were told we would get a confirmation call from the office to confirm the date and estimated time of the crews arrival. We never did. I had to reach out to Rich, Rich had to call Bill, Bill had to call me on Tuesday January 3rd to confirm that the crew was still coming out to do our installation. After this long winded story, we are happy with the product from Key Exteriors. We did not appreciate the lack of communication or constantly having to reach out to get answers. The windows look nice, the installation went smooth, and the crew was very nice and considerate."
"Great work! We contacted Key in June when the bad storm rolled though and did major damage to our siding. Rich showed up and helped us with the insurance paperwork. We decided to do a completely different color and the way Key was able to show us what the house would look like helped us decide for sure. The Insurance approved the work for Key without any hassle (much to my surprise as insurance never seems to work in my favor). Even with all the damage done in the area to many other homes Key made the experience great and timely. The installation crew was very nice and did an amazing job. I’m very picky and expect the best, they cleaned up at the end of every day and stayed in communication with me everyday on the progress they made. The quality of work and professionalism was second to none. Thanks again we are very happy."

- "I would NOT recommend Key Exteriors and it is difficult to separate the company from the product that was installed . Additionally, I have had to have nails at the edges of the roof cut off to avoid rust stains down the side of the house. Apparently this isn't something the salesman or the company considers important. Also, the additional work that was performed was substandard and is now being replaced . I guess the dumb woman wasn't supposed to notice."
