Confidence In Keystone

“It’s pretty powerful that Keystone can design and build a system. Well, design, build, implement and then service that product. So it really is a one-stop shop.”

Exceeding Expectations
Right Number To Call

Everyone has too many things to worry about in today’s environment. There’s so many technical aspects to keep track of. The last thing we’re going to do is be an expert in everything. So it requires experts like Keystone to come in and teach us things we don’t know and make sure we’re in compliance.

Samuel Saxton

Salter Spiral Stair and Paragon Stairs


“They’ve been able to provide accurate drawings, prints to interpret what we have, walk throughs through the buildings identifying equipment ahead of time and challenges went well. Meeting with the technicians sometimes daily or weekly on the job to get updates and to see where they were, challenges they were meeting. Communication was awesome.

Work Flawlessly Together
Keystone Can Handle My Work

“It’s a lot more personal, I think, with [my Life Safety Advisor] Mark. I see him more often. I talk to him more. I got any questions, it’s a lot easier for me to call and get him to answer the phone than working with a large national rep.
