Fantastic decision choosing Keystone. Chad was a dream to work with. Their crews were fantastic. We feel like we live in a new house! We got new siding, which they painted. They repaired areas that we had become blind to. I couldn't recommend this company more!

I hired Keystone to re-do all siding on my Dads house. Wes and the whole Keystone team were professional and top notch from start to finish! My Dad loves his house now thanks to their hard work! The price was extremely fair as well.

Wood or Fiber Cement Siding Installation or Complete Replacement
First of all they have not been in business since 96. Their license says 2014. Everything was going perfect until the siding was to be removed from my house. They ended up tearing up my porch which was not supposed to be touched, and in the process of tearing up my porch, they broke a waterline and flooded the first room of my home. Owner was cooperative at first but then as more problems arose he has now decided to terminate the contract. Their are building code violations my floors still not repaired. It is also illegal to terminate a contract by contractor. So my house is still not done.

Wood or Fiber Cement Siding Installation or Complete Replacement
By far the best experience I could imagine for a large project like ours. We did a full siding replacement and painting of the house. They stayed in touch the whole way through. The crews worked fast and professionally and took care of every detail. We couldn't be happier with Wes and the rest of the team.

Wood or Fiber Cement Siding Installation or Complete Replacement
Let me start off by saying that my wife and I are extremely estatic over the work completed by Keystone Siding & Windows. We couldn't be happier. They replaced the majority of our house siding, prepped and painted the house, all within a very reasonable time-frame. From the very start, Shannon, the project manager and our main contact, was very helpful and extremely knowledgeable regarding the siding that we needed, the prep work to be done and the final painting process for our house. Shannon was always accessible, either in person and/or through text messaging and answered any concerns and questions we had about the siding, painting or the process. Each siding and painting crew were meticulous in their workmanship and it became very obvious to me that they cared about the work that they put into our house, as though it were their very own. Lastly, Shannon worked with his company to get the very best and affordable cost for the work that needed to be done and he stayed within our budget. Great job guys. We will definitely be telling others about your company!!! Robin and Jill Harrison

We loved working with Keystone. From my first call to the office to set up an appointment with Gordon Flores (CEO), I felt like I was working with professional, decent folks. Chad Reis, was our project manager, and he presented super knowledgeable, with years of experience, and was just a delight to collaborate with. Additionally, the siding crew was a hard-working bunch of guys, very respectful, and willing to take direction, as needed. They did a phenomenal job. We were extremely pleased with the final project. With regard to pricing, Keystone was very competitive, not the cheapest perhaps, but an extremely good value for the price. We have done a lot of renovations and house flips over the years, and these guys were wonderful to work with. Can't say enough good things!

Keystone siding exceeded our expectations. Let us first start off with the estimate process as they not only came to my home but provided important information about siding; thus affecting our buying decision. They gave us choices and provided a detailed estimate and what to do expect. The entire crew from siding to painting were efficient and professional. The craftsmanship is superior. The project manager communicated with us through the entire process. I highly recommend this company for your next siding project. They are on time and did not leave until everything was completed to our satisfaction. They cleaned the site and made sure no debris was left behind. Thank you Keystone for making our house the shining jewel of the neighborhood. I will be sure to recommend your services to friends in the areas. I look forward to our next project with youâ windows ð
