What are the stages of pool construction?

The Complete Pool Construction Sequence

Custom in-ground pool construction follows a defined sequence from layout to final inspection. Each stage has dependencies — gunite cannot go in before steel, plaster cannot go in before coping is set. Understanding the sequence helps homeowners know what to expect at each phase of their project and why certain stages take the time they do.

Stage 1: Design Finalization and Permit Application

Before ground is broken, the design must be complete and the permit application submitted. This is not a passive waiting period — Wade uses the permitting window to order long-lead materials (specialty coping stone, custom tile, equipment with extended lead times) so they arrive on site when construction reaches those stages. Typical duration: 4–10 weeks.

Stage 2: Layout and Staking

Once the permit is approved, Wade’s crew marks the pool footprint on the ground using stakes and spray paint, establishing the exact pool perimeter, depth transitions, spa location (if applicable), and equipment pad position. The homeowner walks the staked layout with Wade to confirm positioning before excavation begins. Typical duration: 1 day.

Stage 3: Excavation

A tracked excavator digs the pool basin to the engineered depth profile — typically 3.5 ft in the shallow end sloping to 5–6 ft in the deep end, with the specific profile designed for your pool. Soil is removed from the site. Rocky substrate, high water table, or tight access can complicate and extend excavation. On standard Anne Arundel County lots with normal soil conditions, excavation takes 1–3 days. The hole will be larger than the finished pool to allow room for steel and plumbing work.

Stage 4: Steel Reinforcement Installation

Rebar is tied into a reinforcing grid throughout the pool basin — walls, floor, and all transition zones. Steel spacing and diameter are specified in the structural drawings and verified at the pre-gunite inspection. A tying crew typically completes a standard residential pool in 2–4 days. This is also when conduit for underwater lighting is installed.

Stage 5: Plumbing and Electrical Rough-In

Plumbing lines for returns, main drains, skimmers, spa jets (if applicable), and water features are installed before gunite. Electrical conduit for the equipment pad, underwater lights, and automation runs are also roughed in at this stage. This work happens concurrently with or immediately following steel. Typical duration: 2–5 days. A county rough-in inspection may be required at this stage before gunite can proceed.

Stage 6: Gunite or Shotcrete Application

Gunite (dry-mix pneumatically applied concrete) or shotcrete (wet-mix) is sprayed at high pressure over the steel framework, forming the structural shell of the pool. The application of a standard residential pool takes 4–8 hours. After application, the shell must cure for a minimum of 28 days before the interior finish is applied. During the cure period, the shell is kept wet by daily hand-watering (or automated spray) to prevent surface cracking. Other work — coping, decking — can begin during the cure period.

Stage 7: Coping and Waterline Tile

Coping (the cap stone or paver around the pool perimeter at water level) is installed after the shell has achieved initial cure. Waterline tile is set at the same time. Coping material — natural stone, concrete paver, or brick — is selected during the design phase. This stage requires careful setting to achieve level, consistent elevation all the way around the pool. Typical duration: 3–7 days depending on pool size and coping material.

Stage 8: Decking

Pool deck and surrounding hardscape are installed after coping is set. Concrete decking requires forming, pouring, and finishing; paver decking requires base preparation, setting, and jointing; natural stone requires precision cutting and setting. Outdoor kitchen structures, fire features, and retaining walls are built during this phase. Typical duration: 1–3 weeks depending on scope and materials.

Stage 9: Equipment Installation

Pool pump, filter, heater or heat pump, automation controller, salt cell (if saltwater), and all associated plumbing and electrical connections are installed at the equipment pad. This work is coordinated with the electrical sub-contractor for final wiring and panel connection. Automation systems are programmed and tested. Typical duration: 2–5 days.

Stage 10: Interior Finish

The pool interior — plaster, quartz aggregate (Pebble Tec/Pebble Sheen), or pebble finish — is applied to the cured gunite shell. This is a one-day application for a standard residential pool. The pool must be filled with water within 24 hours of plaster application to prevent cracking and staining. The fill process itself takes 24–48 hours. After filling, initial chemistry balance (startup) takes 1–2 weeks of active management.

Stage 11: Final Inspection and Walkthrough

A county inspector visits the site to verify all work matches the approved plans — structural, electrical, plumbing, and safety barrier. Once the final inspection passes, the certificate of occupancy is issued for the pool and the homeowner receives their final walkthrough with Wade covering equipment operation, maintenance schedule, and chemistry basics. Typical duration: inspection scheduled 3–7 days after completion, walkthrough same day.
