Patios
A well-built patio is the foundation of outdoor living — and we build them to last a lifetime. Our custom patios are crafted using premium materials including natural flagstone, bluestone, slate, pavers, brick, and concrete, selected specifically for each property's architecture and the homeowner's vision. We begin every patio project with proper site excavation, base compaction, and drainage engineering to ensure the surface remains level, stable, and structurally sound for decades. Whether you're envisioning an intimate courtyard, a large-scale entertaining space, or a resort-style backyard retreat, we design each layout with precision and build it with discipline. Every cut, every joint, and every edge reflects the craftsmanship standard that has defined Edgar Stone Masonry LLC across 36+ years of residential masonry leadership in the Washington metropolitan region.
Outdoor Kitchen Masonry
An outdoor kitchen built in stone is a permanent statement of luxury — and it demands a masonry team with the experience to execute it correctly. We design and construct custom outdoor kitchen spaces using natural stone, fieldstone, brick, concrete block, and premium masonry finishes engineered for both beauty and long-term performance. From full cooking stations with stone-wrapped grills and built-in appliances, to elegant bluestone or flagstone countertops, bar islands, and integrated seating walls, every element is built with structural precision and refined detailing. We coordinate the masonry work around your layout, your appliances, and your outdoor living vision — ensuring every surface is level, sealed, and built to withstand the elements for years to come. This is outdoor living elevated to an architectural level.
Chimneys
A chimney is one of the most structurally complex and safety-critical elements of any home — and it requires masonry expertise that goes far beyond surface work. We build, restore, and fully reconstruct chimneys using high-grade natural stone, brick, and professional-grade mortar mixed and applied to exacting standards. Our chimney work covers new construction from the footing up, full crown and cap rebuilds, tuckpointing, spalling brick repair, flashing correction, and complete structural reconstruction for chimneys that have deteriorated over time. Every project is evaluated for structural integrity before the first stone is set, and every phase is executed with the attention to safety, alignment, and finish quality that a permanent structure demands. Whether interior or exterior, our chimneys are built to perform through decades of weather and use.
Driveways
Your driveway is the first impression of your home — and it should reflect the same quality as everything behind it. We install custom driveways using stamped concrete, exposed aggregate, natural stone pavers, cobblestone, brick, and premium masonry materials selected for durability, load capacity, and refined visual appeal. Every driveway project begins with proper subgrade excavation, compaction, and base preparation — because a driveway that fails does so from the ground up, not the surface. We engineer each project for proper drainage, weight distribution, and long-term structural performance, then finish it to a standard that enhances your home's curb appeal and holds its appearance through years of daily use. No shortcuts. No low-grade materials. Just precision masonry built to last.
Walkways
A custom stone walkway transforms the approach to your home from functional to architectural. We install premium walkways using natural flagstone, bluestone, slate, brick, pavers, and concrete — each material selected to complement your home's style and integrate naturally with the surrounding landscape. Every walkway begins with careful grading, excavation, and base preparation to ensure long-term stability and proper drainage. We lay each stone with precision, maintaining consistent joint spacing, level surfaces, and clean edges from start to finish. Whether it's a sweeping curved path through a landscaped garden, a formal entry walkway leading to your front door, or a connecting path between outdoor living spaces, our craftsmanship ensures every step is structurally sound and visually refined. Built for beauty. Built to endure.
Retaining Walls
Retaining walls are one of the most structurally demanding elements in residential masonry — and one of our core specialties. We design and build custom retaining walls using natural stone, fieldstone, concrete block, brick, and premium masonry materials engineered for long-term structural performance. Every wall begins below the surface — with proper excavation, compacted gravel base, and drainage systems that prevent hydrostatic pressure buildup for decades. We build walls of all scales, from small garden terraces to large-scale structural walls managing significant elevation changes across sloped properties. Each project is evaluated individually for soil conditions, load requirements, and site drainage before a single stone is placed. The result is a wall that holds its position, maintains its appearance, and performs reliably through freeze-thaw cycles, heavy rainfall, and years of ground movement. Structural precision from the ground up — that is the Edgar Stone Masonry LLC
Terraced Retaining Walls & Flagstone Steps
When a property demands both structural engineering and architectural beauty, a terraced retaining wall system with integrated stone steps is the defining solution. We build multi-level terraced walls using natural stone, flagstone, bluestone, and fieldstone — engineered to manage elevation changes while creating a landscape that looks like it was always meant to be there. Every terrace begins below grade with deep excavation, compacted base, and drainage systems built to handle groundwater across multiple wall levels. Each tier is finished with hand-selected flagstone or bluestone caps — laid flat, tight, and level. Steps are cut and set individually for safety, comfort, and visual flow from top to bottom. Built from the ground up — the Edgar Stone Masonry LLC way.
Concrete Work & Structural Slabs
A properly poured concrete foundation is what separates masonry that lasts from masonry that fails. We pour and finish professional-grade concrete slabs, footings, and structural bases for patios, retaining walls, driveways, and outdoor living spaces of all scales. Every pour is reinforced with steel rebar — placed and tied before the concrete mix is poured, creating an internal steel skeleton that locks the slab in place, resists ground movement, and prevents cracking under load. Using high-grade concrete mixes with proper rebar reinforcement, every foundation is engineered for maximum load capacity and long-term structural performance. Our concrete work is executed with the same precision as every other phase of our builds. Because no matter how beautiful the stonework above looks — it is only as strong as the foundation beneath it.
