WHO WE ARE.
At Keystone Granite, we are dedicated to providing you with the best quality granite that Muskoka has to offer. Our products provide the perfect backdrop for a natural Muskoka look and feel. We provide beautiful wire sawn Muskoka granite to local landscapers, builders, land developers and home owners. We cut our granite on site and provide flagstone, stair treads and granite blocks. Please check out our price list for more details, or feel free to contact us to discuss any further questions that you might have, we'd be happy to chat!
All of our stone comes from a family owned quarry located in Huntsville. At Keystone Granite we blast, cut and process all of our rock on location at our quarry on Highway 60, making it possible to provide you with customized products that meet the demands of your next project.
