MPS Stone Slinger is a locally owned and operated aggregate delivery company based in Seguin, Ontario, proudly serving Parry Sound and surrounding areas. Built on reliability, precision, and honest service, we specialize in stone slinger deliveries for both residential and commercial projects.
Led by Chris Kappes, MPS Stone Slinger was created to provide a smarter, cleaner, and more efficient way to deliver aggregate materials. Our stone slinger equipment allows us to place stone, sand, gravel, topsoil, and mulch exactly where it’s needed, even in tight or hard-to-reach areas — saving time, labour, and cleanup on every job.
We work closely with contractors, builders, landscapers, and homeowners who value dependable service and quality materials. All of our aggregates are locally sourced, and every project is approached with care, professionalism, and attention to detail.
At MPS Stone Slinger, we believe in doing things right the first time. Showing up on time, communicating clearly, and delivering consistent results is what keeps our clients coming back.
When you choose MPS Stone Slinger, you’re choosing experience you can trust and service you can rely on.
