Actaeon installs natural stone features — including flagstone patios, stone steps, dry-stack and mortared garden walls, stone paths, and decorative stone accents — for residential and commercial properties in Washington DC, Maryland, and Virginia. Stone type is matched to the application: bluestone for formal work, fieldstone for informal settings, with proper base preparation for every installation in DMV clay soil.
Natural stone is the most durable hardscape material available, and the most unforgiving to install incorrectly. A properly set flagstone or dry-stack wall will outlast everything around it.
Stone applications we build
- Flagstone patios. Natural bluestone, fieldstone, and quartzite laid in mortar or set dry in compacted aggregate. The most enduring patio surface available.
- Stone steps. Natural stone treads and risers for grade changes — more durable than concrete and more visually compelling than timber.
- Garden walls. Dry-stack or mortared fieldstone and ledgerock walls as low landscape dividers, planting bed edging, or decorative features.
- Stone paths and walkways. Flagstone, stepping stones, and decomposed granite paths through garden areas and between hardscape elements.
- Decorative stone features. Boulders used as focal points or grade anchors, stone mulch applications, and accent elements within planting beds.
Why stone selection matters as much as installation
Bluestone is the default choice for formal patios and walkways — tight grain, consistent thickness, easy to cut. Fieldstone suits informal walls and naturalistic settings where the irregular texture is an asset. Slate is beautiful but splits and flakes in freeze-thaw cycles without proper mortaring, making it a poor choice for exposed horizontal surfaces in the DMV climate. We'll match material to application, not just to aesthetic preference.
Base preparation is equally critical for stone as for any other hardscape. A dry-laid flagstone patio requires 4 to 6 inches of compacted gravel base with a sand setting bed. Skip the base and the flags shift, heave, and crack within two winters in Maryland clay soil.
How we install stone — process and details
The installation process varies by application, but the base work is consistent. For a flagstone patio: excavation to 6 or more inches below finished grade, 4 to 6 inches of compacted gravel base, 1 inch of sand setting bed, and individual flags set to the correct height and slope. We check each flag with a level as we go. For mortared stone work, we pour a concrete subbase and use polymer-modified mortar rated for freeze-thaw exposure — standard gray mortar fails at the joints within a few years in DMV winters.
Stone steps need extra attention because they carry foot traffic on a sloped surface. Treads must be level front-to-back and pitched slightly forward — usually 1/8 inch per foot — to shed water without being noticeable underfoot. We set each course, check for level, and adjust before the next course goes in. Steps that aren't level are a liability once they're wet or icy. We don't rush the check.
Stone work in Montgomery County, Prince George's County, and DC
We've installed stone patios, steps, walls, and paths throughout the DMV — Montgomery, Prince George's, Howard, and Anne Arundel Counties in Maryland, Fairfax County in Virginia, and throughout Washington DC. Properties near streams, wetlands, or the Chesapeake Bay Critical Area may have restrictions on impervious surface coverage or grading near water features. We know the permit requirements in each jurisdiction and flag them before work starts rather than discovering them after the patio is in.
