Company Profile
Marenakos Rock Center has been the Seattle area's natural-stone authority since the mid-1950s, a family-owned business through three generations operating an 8-plus-acre stone yard off I-90 in Issaquah. We stock domestic and imported natural stone in remarkable depth: flagstone, river rock, basalt columns, cobblestones, drystack wall stone, dimensional pavers, natural and full-bed veneer, steps, treads, capstones, benches, landscape boulders and decorative aggregates. An in-house fabrication shop cuts, splits, thermal-finishes, polishes, core-drills and sandblasts to spec, and we deliver with certified crane operators for boulder setting. We also carry Isokern fireplace products, fire features, mortars and sealers, serving homeowners, architects, contractors and masons. With inventory that changes daily and expertise built over decades, Marenakos is where Puget Sound's hardscape projects start. For natural stone and masonry supply in the Seattle metro, the trade comes to Marenakos Rock Center.

“We shifted our custom residential framing packages to Marenakos Rock Center last season. Their takeoff estimators are meticulous—they spotted a load-bearing transfer discrepancy in our drawings that would have cost us thousands in framing corrections. Elite service.”
“Their crane truck operators are the best in the business. Staged three heavy framing drops on a steep, narrow hillside lot with zero damage to the trees or neighbor's fence. Very dependable logistics dispatch.”
“Top-notch independent supplier counter. They don't just scan tags—they actually understand engineered wood and local code requirements. Whenever I call, I get direct answers on dispatch times and pricing buffers.”
