Why Silver Spring Homeowners Choose SiteDoctorMD for Flagstone
Flagstone is a craftsman material — every piece is shaped, fit, and set by hand. The difference between a flagstone patio that looks great for 30 years and one that grows weeds, rocks underfoot, and pops loose in three winters comes down entirely to the base and the joint detail. We build both correctly.
Whether you want a casual, irregular look with tight sand joints or a formal cut-bluestone patio set in mortar over a concrete base, we hand-fit every stone and grade for proper drainage. As a family-owned business, we're directly accountable to our Montgomery County neighbors.
Our Flagstone Patio Process
Free Design Consultation
We discuss stone selection (irregular vs cut, color, thickness), layout, and use, then provide a detailed written estimate at no charge.
Excavation & Base
We excavate to the correct depth and install a compacted aggregate base — deeper for mortared patios so freeze-thaw cannot crack the slab.
Stone Selection & Layout
Stones are sorted by size, color, and thickness, then dry-fit on-site so the layout looks balanced before anything is set.
Setting the Stone
Each piece is hand-fit and set — into screeded bedding sand for dry-laid patios, or into a mortar bed over reinforced concrete for mortared work.
Jointing
Joints are filled with polymeric sand (dry-laid) or color-matched mortar (mortared) and tooled cleanly so water drains and weeds stay out.
Final Walkthrough
We wash down the patio, walk it with you, address any questions, and your 5-year workmanship warranty begins immediately.
