Flagstone Installation

What This Service Involves

Flagstone is thin, flat sedimentary rock split into irregular slabs, prized for the loose, organic look it lends to woodland and cottage gardens throughout the Puget Sound region. Each piece is hand-fitted like a puzzle, so a finished path feels like it grew out of the landscape rather than being installed on it. We can set flagstone dry over compacted gravel with planted or gravel joints for maximum drainage, or wet-mortar it over a slab for a firmer surface. Because our winters are so wet, we grade carefully and choose denser flagstone that resists flaking from freeze-thaw.

Benefits

Natural, non-uniform look that suits garden settings; Flexible dry-set or mortared installation options; Open joints can be planted with moss or groundcover; Excellent drainage when dry-laid over gravel; Blends beautifully with native PNW plantings

Our Process

1) Plan the layout and confirm drainage direction; 2) Excavate and compact a gravel base; 3) Dry-fit slabs to minimize gaps and trip edges; 4) Set stones on bedding sand or mortar; 5) Fill joints with gravel, sand, or planting soil

What Affects the Cost

Flagstone type, thickness, and slab size; Total square footage and path length; Hand-fitting and cutting labor; Dry-set versus mortared method; Joint fill material and plantings

Best Time of Year

Best installed spring through fall when dry-set joints can settle, though sheltered paths can be built during drier winter breaks.
