How Long a Pool Build Takes in the Hill Country
Hoping to swim by summer and not sure when to start? A pool build is a string of steps, and each one can wait on something: a permit, the weather, rock or an inspection.
Knowing the order helps you plan. Here it is.
The order
The usual steps.
- Design and quote. Layout, finish and equipment get settled and written down.
- Permit. The city or county reviews the plans before work starts.
- Dig. The pool is laid out and dug. Rock can add days here.
- Steel and plumbing. Rebar and pipes go in, and an inspection often follows.
- Shell. Concrete is sprayed into place and left to cure.
- Tile, coping and deck. The edges of the pool and the deck around it.
- Equipment and electrical. The pump, filter and controls get set and wired.
- Finish, fill and start-up. The inside finish goes on, the pool fills and the water is brought into balance.
Paperwork
Permits come first.
What the city wants varies. New Braunfels, for example, asks for a site plan, a cross-section of the pool, barrier details and electrical plans in one package.[1] Boerne asks for a permit application and a site plan for any below-ground pool.[2] A complete package up front helps avoid back-and-forth.
San Antonio's permit form lists several inspections during the build, ending with a final inspection.[3] Each one has to be booked and passed before the next stage can start.
Our pool permit guide covers what each city checks.
What slows it
What can add time.
- Rock. Solid limestone digs slower than soil.
- Rain. Wet ground and storms can stop digging and concrete work.
- Engineering. Tall walls, slopes or a pool near the house may need an engineer. New Braunfels asks for an engineer's certification for pool digs within 10 feet of a building foundation.[1]
- Changes. Changing the design once work starts can mean new drawings, new pricing and sometimes another permit review.
- Water. Drought stages can affect when and how you fill.
After the water
The first month counts.
Once the pool is full, the work is not quite done. The National Plasterers Council says a new finish is especially likely to stain, scale or discolor in the first 28 days.[4] Plan for daily brushing and testing that month. Our first 28 days guide has the steps.
No one can give you a firm date before seeing your site. Your project gets a written scope and a schedule estimate, and rock or weather can move it.
