The most common question we hear after "how much does it cost?" is "how long will it take?" The honest answer: a custom gunite pool in Houston takes 10–14 weeks from permit approval to swim-ready, and 14–18 weeks from contract signing. Here's exactly what happens at each stage — and what can slow things down.
Understanding the timeline helps you plan around summer, school schedules, and outdoor entertaining. The best time to start the process is in the fall or winter — so your pool is ready when Houston's heat arrives.
Quick Summary
Phase-by-Phase Pool Build Timeline
Here's what actually happens during each phase of a custom gunite pool build in Greater Houston — from the first site visit to the day you swim.
Design & Proposal
Weeks 1–2We meet at your property, walk the yard, and discuss your vision. After the site visit, we prepare a detailed written proposal with itemized scope and pricing. Once you approve the design and sign the contract, we move to permitting.
Permits & Engineering
Weeks 2–5We submit permit applications to your city or county building department and, if required, to your HOA for design review. Harris County permits typically take 2–4 weeks. Some cities (Katy, Sugar Land, The Woodlands) have their own permit offices with varying timelines. We handle all of this — you don't lift a finger.
Excavation
Day 1–3 of ConstructionOnce permits are in hand, excavation begins. For a standard 14×28 pool, excavation typically takes 1–3 days. Access to the backyard, soil conditions, and proximity to existing structures all affect this timeline. Our crews coordinate utility locates before any digging begins.
Steel & Plumbing
Days 4–10After excavation, our steel crew forms the rebar cage in the exact shape of your pool design. Plumbing rough-in — all the pipes for returns, suction, and water features — is installed simultaneously. This phase typically takes 5–7 days and is inspected before gunite application.
Gunite Shell
Day 11–12Gunite is applied in a single continuous session by our experienced nozzlemen. For a standard pool, the shell is typically complete in one day. The concrete must cure for a minimum of 28 days before the interior finish is applied — this is non-negotiable for structural integrity.
Tile, Coping & Decking
Weeks 6–9While the shell cures, tile and coping installation begins. Decking — whether concrete, travertine, or pavers — follows. This phase is the most visible transformation of your backyard and typically takes 2–4 weeks depending on the scope and material selection.
Equipment & Electrical
Weeks 8–10Pool equipment (pump, filter, heater, automation system) is installed on the equipment pad. Electrical connections are made by our licensed electrician and inspected by the city. This phase overlaps with decking and typically takes 1–2 weeks.
Interior Finish & Fill
Weeks 10–12The interior finish — plaster, pebble, or tile — is applied and the pool is immediately filled with water. The startup process (balancing chemistry, brushing the new finish, running the equipment) takes 1–2 weeks. Your pool is typically swim-ready 10–14 days after the finish is applied.

What Causes Pool Construction Delays in Houston?
Any builder who promises a firm 10-week timeline without buffer is setting you up for disappointment. Here are the most common causes of delays — and how a good builder manages them.
Permit Delays
The single most common cause of timeline extensions. Permit offices in Harris County, the City of Houston, and suburban municipalities all have different processing times — and they fluctuate with application volume. HOA design review adds another layer. We submit permits immediately after contract signing and track them actively, but we always build 2–4 weeks of buffer into our project schedules.
Houston Rain
Houston averages over 50 inches of rain per year — more than Seattle. Excavation, gunite application, and decking all require dry conditions. We schedule around the forecast and maintain buffer in the schedule for weather delays. Spring (March–May) is historically the wettest season; fall and winter builds tend to have fewer weather interruptions.
Material Lead Times
Custom tile, specialty coping stone, and certain equipment can have lead times of 4–8 weeks. We order materials immediately after contract signing to minimize this risk. If you select a material that's backordered, we'll tell you upfront and offer alternatives.
Utility Conflicts
Occasionally, excavation reveals underground utilities (gas lines, irrigation systems, electrical conduit) that weren't on the utility locate maps. This is rare, but when it happens, it requires coordination with the utility company and can add 1–2 weeks.
Change Orders During Construction
Scope changes after construction begins — adding a water feature, upgrading the finish, expanding the deck — can add time. We encourage clients to finalize all design decisions before we break ground to avoid this.
The Best Time to Start Your Pool in Houston
If you want to swim by Memorial Day, you need to sign a contract by November or December at the latest. Here's the math: 4–6 weeks for permitting + 10–12 weeks of construction = 14–18 weeks minimum. Working backward from May 25, that puts your contract signing in late January at the absolute latest — and that assumes no delays.
The smartest approach: sign in September or October. You'll beat the spring rush (when every pool builder in Houston is slammed), get your permits processed faster, build during the drier fall/winter months, and have your pool ready well before the heat hits. Fall builds also tend to have fewer weather delays and more contractor availability.
