If you are looking for a custom pool builder in Caldwell ID, you probably already have a spot picked out. Maybe it is the open grass behind the house. Maybe it is the corner where the kids set up a blow-up pool every July. We are HDT Pools in Boise, a family-owned crew that has built gunite pools since 2014. We build every pool with our own people. No subcontractors.
Caldwell is about a 30-minute drive from our shop on W Amity Road in Boise. We come out, walk the yard with you, and tell you plainly what will fit and what it will take.
What We Check First on a Caldwell Lot
Before we talk about shapes or tile, we look at the ground and the rules. These five things come up on almost every Caldwell job:
- City or county permit. Homes inside Caldwell city limits go through the City of Caldwell. Lots outside town go through Canyon County. We figure out which one applies before we draw anything.
- Septic tanks and drain fields. Many rural Caldwell homes are on septic. The pool has to stay clear of the tank and drain field, and that can decide where the pool goes.
- Irrigation lines and ditches. Lots of properties here use canal water for the lawn. We find where those lines run and plan around them so nobody hits one on dig day.
- Room for equipment. A dig needs space for an excavator and a gunite truck. Older homes near downtown can have tight side yards, so we measure gates, fences, and trees early.
- HOA rules. Newer subdivisions often have rules on fences, setbacks, and equipment. If you have HOA papers, bring them to the first visit.
Catching these early keeps surprises out of the price and the schedule.
Why We Build Gunite Pools in Caldwell
We build gunite pools, also called shotcrete pools. The shell is sprayed on site over a steel rebar frame. That means the pool can be any shape, size, or depth you want.
That matters in Caldwell. One yard might be a wide half acre. The next might be a narrow lot off Cleveland Boulevard. A fiberglass shell comes in set sizes. A gunite pool is built to your yard. You can read more about custom swimming pool construction, gunite pool construction, and inground pool installation on our other pages.
Caldwell summers often hit the 90s, and big open lots do not have much shade. So we plan around the afternoon sun. A tanning ledge can go where the sun is strongest. A lighter concrete pool deck stays easier on bare feet than a dark one. Our custom pool design process covers these choices before any digging starts.
Plan Early If You Want to Swim This Summer
Most pools in the Treasure Valley get built in spring and summer, so schedules fill up. We also take on a limited number of projects each year so each one gets our full attention. If you want to swim by July, the best time to call is winter. Design, permits, and the dig all take time, and weather can push things back.
Why Caldwell Families Call HDT
- One crew from start to finish. The same team digs, forms, plumbs, sprays the gunite, sets tile and coping, and pours the deck.
- Family owned since 2014. You talk to the people building your pool.
- Homes and commercial work. We build backyard pools and also HOA, hotel, and public pools.
- We are clear about what we do not do. We build and remodel pools. We do not offer weekly pool maintenance.
One homeowner had us build a 16 by 36 foot gunite pool in 2023. Going into the fourth season, they told us it still looks and works great, and their family uses it all the time. That is the kind of result we aim for on every job.
Where We Build in Caldwell
We work all over town. Near downtown, Indian Creek Plaza, and the older streets off Blaine Street and Cleveland Boulevard, yards tend to be tighter, so access planning comes first. Around the College of Idaho, lots vary from street to street. Newer subdivisions and bigger parcels off Ustick Road and Orchard Avenue usually have room for a larger pool and a wide deck. Farm-edge lots on the south side of town often mean septic and irrigation planning.
Many of our customers also have family or friends in Nampa and Middleton, and we build there too.
The Process of Building a Custom Pool That Fits a Caldwell Property
Here is what happens from our first visit to the day you swim.
Step 1
We Look at How the Yard Actually Sits and Functions
We walk the yard with you, measure gates and side yards, and find septic, irrigation lines, and slopes before we pick a spot.
Step 2
We Plan Around Sun, Exposure, and How the Family Will Use the Space
Caldwell afternoons get hot. We place ledges, seating, and deck space based on where the sun hits and how your family plans to swim.
Step 3
We Sort Out the Build Details Before Heavy Work Starts
We confirm whether the City of Caldwell or Canyon County handles your permit and plan the dig route for the excavator and gunite truck.
Step 4
We Build the Pool as Part of the Full Backyard Layout
Our crew digs, sets rebar, runs plumbing, sprays the gunite shell, and adds tile, coping, and the deck. No subcontractors.
Step 5
We Finish with a Pool That Fits the Property, Not Just the Plan
We walk the finished pool with you, show you how the equipment works, and make sure everything is ready to use.
