The main candidates are natural stone, concrete pavers, and brick, and all three work here provided the base is right. Bluestone is common and well suited to the region — durable, handles freeze-thaw, and sits naturally with older Delaware County homes. Concrete pavers are engineered for exactly this climate, come in consistent thicknesses that make installation precise, and individual units can be lifted and reset if anything ever settles. Brick matches brick houses beautifully but is somewhat more prone to edge chipping and to moss in shaded, damp areas.

For a typical residential patio, plan on several days to about two weeks depending on size, access, and how much excavation is involved. The sequence is excavation, base installation and compaction, then setting the surface, and the base work regularly takes as long as the visible work does. Access matters more than people expect: a back garden reachable only through a narrow side gate means material moves by wheelbarrow rather than machine, which adds time. Weather also governs, since base compaction and jointing both need reasonably dry conditions.

Base failure, essentially always. If the excavation was too shallow, the base material was the wrong type, or it was dumped and tamped once rather than compacted in lifts, it continues consolidating under load and the surface follows it down unevenly. Water is the accelerant: runoff from a downspout crossing under the patio washes base material out and creates voids. The good news with pavers and stone is that a settled area can usually be lifted, the base corrected, and the same units reset — a repair that is not available on poured concrete.

Yes, always, and away from the house. A patio built dead level holds water on the surface and directs rainfall toward the foundation rather than away from it, which is a far more expensive problem than a patio. The standard is a slight, consistent fall of roughly a quarter-inch per foot — enough to move water reliably, gentle enough that furniture sits level and nobody notices. Where the ground falls toward the house rather than away, the design has to solve drainage deliberately before the patio goes in.

Yes, and building them at the same time as the patio is both cheaper and better. A seat wall, steps down to a lawn, pillars, or an outdoor fireplace all share base preparation and material deliveries with the patio, and more importantly they can be integrated properly — courses and joints lining through, borders running into the wall base — rather than looking added on. Since masonry is our whole trade rather than a landscaping sideline, these are the same crew and the same job, not a subcontract.
