The week on site, day by day
For a typical 300 to 500 square foot patio on a site with reasonable access and no surprises:
- Day 1 — Layout and excavation. The shape gets marked, the sod and topsoil come off, and the hole is dug to the depth the base needs. Spoil goes off site.
- Day 2 — Base. Crushed stone goes in and is compacted in lifts of a few inches at a time, not in one layer. This is the day that decides whether the patio is still flat in five years.
- Day 3 — Bedding and edge. A screeded bedding course to a consistent depth, and the edge restraint that stops the field spreading outward under load.
- Days 4–5 — Laying. Pavers or stone set, cut in at the edges, pattern held true.
- Day 5–6 — Joints and clean-up. Polymeric sand or mortar joints depending on the build, final compaction, wash down, and the site put back.
What makes it longer
Rock, first and most often. Shallow ledge is common across Putnam and Yorktown, and a day of excavation becomes three when a hammer has to come out.
Access, second. If a machine cannot reach the work, every ton of base and every pallet of stone moves by wheelbarrow, and a five-day job becomes a nine-day one with the same crew.
Weather, third, and not in the way people expect. Rain does not stop a patio — working saturated ground does. Compaction will not achieve density in mud, so a wet week can cost days even when it is not raining on any of them.
Steps, walls, fire features and utilities. Each is separate work. A patio with a seating wall and a fire pit is not a patio job with extras, it is roughly double.
The part before the crew arrives, which is usually longer
Estimate and site visit: a few days to a week. Design and material selection: one to three weeks, and this is where most schedules actually slip, because choosing stone is the enjoyable part and there is no deadline on it.
Permits, where the job needs them: this varies by town and it is not something a contractor can compress. In the Town of Carmel a patio needs a permit unless it sits under twelve inches in height. If the work triggers a stormwater plan — 5,000 square feet of land disturbance inside the New York City watershed, against an acre elsewhere in the state — that is a review, not a form.
Then scheduling. Masonry in this region is seasonal, and the calendar for spring fills up in winter. A patio booked in February is built in April; the same patio booked in May is built in July.
Cure time on anything with concrete in it
If your build includes poured steps, footings or a mortar-set surface, add cure time and treat it as fixed. Foot traffic at 24 to 48 hours, vehicles on new concrete at seven days. It is not a scheduling suggestion however dry the surface looks — loading green concrete is how you get cracks in the first week.
