About Keystone Remodeling
Keystone Remodeling began as Keystone Basements back in 2004, when Mark Walser, a custom residential remodeler, started the business out of his home. In 2009 the company grew to include kitchen and bathroom remodels.
The goal has always been clear: high-quality remodeling. By building long-term subcontractor relationships, Keystone delivers quality, on-time remodels. Talk to Mark about basements and baths, or Brian Robbins about kitchens — both at 470.KEY.TEAM.

What homeowners say
“The team at Keystone did an excellent job with our kitchen remodel. First we started with the design phase — we had a few design elements we wanted to incorporate and the designer, Lindsay, really brought our ideas to life.”
“We just completed a primary bathroom renovation with Keystone Remodeling and could not be happier with the results. Our project manager, Wilson, did a great job making sure every detail was completed correctly.”
“Amazing experience from start to finish! Brian and Lindsey perfectly designed my kitchen with all of the small details and even figured out how to put in a hidden pantry! I LOVE it! Josh, my project manager, was wonderful!”
