At Keystone Millwork & Installation Company, we specialize in designing and manufacturing custom casework and millwork solutions to realize the vision of architects and designers. Whether it's cabinetry, countertops, doors, or shelving, we deliver high-quality craftsmanship in every project.
The success of every project begins with the strength of the team behind it. Our leadership and dedicated craftsmen bring over a century of combined experience in commercial casework, delivering precision, reliability, and pride in every detail. From concept to completion, we’re committed to getting it right—because your project deserves nothing less.
We supply Division 6 architectural woodwork crafted from premium materials, including plastic laminate casework, countertops, lockers, and benches. Our product offerings extend to solid surface, quartz, and natural stone tops, as well as select hardwoods, stained finishes, and high-performance painted surfaces. Every component is built to meet specification standards—ensuring durability, design integrity, and a refined finish across every project.
We understand that delays can disrupt schedules and drive up costs. That’s why we prioritize efficient production and reliable timelines—ensuring your custom casework is delivered on schedule, so your project stays on track and your business keeps moving.
We take pride in the quality of our work and stand firmly behind every project we complete. Your satisfaction is our priority—if your custom casework doesn’t meet expectations, we’ll work closely with you to resolve it promptly and ensure the final result aligns with your vision.
We manufacture the majority of our products in-house to ensure quality, precision, and control. For projects where our trusted partners are better suited to meet specific requirements, we leverage their specialized capabilities—always with a focus on delivering on time, on budget, and to specification. Regardless of the source, Keystone remains your single point of contact, ensuring a seamless experience from start to finish.
