“We used Keystone for a recent deck replacement project.  They were patient as we changed our mind on the design several times.  They did a great job of communicating throughout the project, and the job was done in a timely manner with high quality.”

– Joe Keer

“Couldn’t be happier.  Their sales associate Mahlon made the design and specification process simple and fun.  Keystone was not the least expensive option, but they were the most trustworthy.  The team that built the deck was awesome.  They were all beyond friendly and it was obvious that they knew what they were doing.”

– Joe Roth

“From the start, Marv worked very hard with me to come up with a great design for my deck and gazebo.  The builders Mike, Allan, and their crew were meticulous in their work, very polite, conscientious, and respectful.  It was a pleasure to work with such a professional company.”

– Sandra Cheung

“Having just come off a horrific pool construction project with a horrible company, we were very nervous about another group of contractors.  However, Keystone has happily proven us wrong in our worries, and we could not be happier with our finished project.  Our project was everything we hoped it would be and more.”
