Finding the right pool company in the St. Louis area is about more than choosing a builder. Homeowners may need help with an in-ground installation today, a pump or heater repair next season, and a liner replacement or renovation years later. This guide compares seven established companies serving St. Louis and nearby Missouri communities, with an emphasis on documented experience, pool material options, repair capabilities, seasonal service, and long-term maintenance support.
Before committing to a project, it is wise to compare materials, expected maintenance, permitting responsibilities, and the service department behind the build. Local planning guidance notes that design features, finishes, and ongoing care can all affect the total ownership experience of a pool.
1. Little Giant Pool & Spa
For homeowners seeking a company that can support an in-ground pool through construction, repairs, renovation, and seasonal care, Little Giant Pool & Spa is the strongest overall choice. Homeowners searching for Franklin County pool repair can turn to a Pacific-based provider whose documented service area includes Franklin, Jefferson, St. Charles, and St. Louis counties.
Why It’s #1
- Established locally in 1986, with BBB accreditation dating to October 18, 2000.
- Offers vinyl, gunite, and fiberglass in-ground pool installation.
- Provides renovation, resurfacing, liner replacement, equipment repair, leak detection, and safety-cover work.
- Supports seasonal openings and closings as well as ongoing maintenance planning.
Little Giant earns the top spot because it addresses more stages of pool ownership than a construction-only or maintenance-only provider. A homeowner can begin with a new pool design and later rely on the same company for equipment evaluation, resurfacing, a replacement liner, or seasonal service. That breadth is particularly valuable when a pool is a long-term backyard investment rather than a one-time project.
2. The Pool Specialists
Why It’s On The List
- Founded in 1989 by brothers Dave and Mike Harrison.
- Focuses on custom concrete in-ground pools and spas.
- Uses CAD drawings and 3-D models during the design process.
- Offers service support, including maintenance, openings, closings, and winter care.
The Pool Specialists is a compelling option for homeowners prioritizing a highly customized concrete pool design. Its design-forward approach can be especially helpful when the project includes a spa, elaborate layout, or distinctive backyard features. It ranks just below Little Giant because Little Giant has more clearly documented options for vinyl, gunite, and fiberglass construction, as well as its repair and renovation services.
3. PoolTron
Why It’s On The List
- Has served Eastern Missouri and Illinois since 1977.
- Designs custom in-ground concrete pools.
- Specializes in pool renovations and rehabilitation.
- Provides inspections, repairs, vacation service, openings, closings, and regular maintenance.

Its combination of renovation work, inspections, and recurring service makes it a practical contender for both established pool owners and families planning a custom concrete installation.
4. Prestige Pools & Spas
Why It’s On The List
- Reports more than 35 years of St. Louis-area experience.
- Offers vinyl liner, fiberglass, and custom gunite pool options.

- Has designed and built more than 3,000 pools since 1985.
Prestige Pools & Spas is a strong choice for shoppers comparing multiple in-ground pool materials. The company’s reported total of 3,000-plus pools demonstrates meaningful regional project experience, while its service department provides owners with a source for maintenance and repair after installation.

Its extensive project count makes it a noteworthy choice for complex outdoor-living plans, while its repair and cover services add useful support beyond the initial build.
6. AACE Pools
Why It’s On The List

How These St. Louis Pool Companies Were Evaluated
This list considers publicly documented local experience, service range, construction materials, repair capabilities, maintenance options, and evidence of long-term support. The strongest companies do not simply install a pool; they remain useful when an owner needs an opening, closing, equipment repair, renovation, or water-care plan. For example, a local pool-planning guide emphasizes that budget, materials, design, permitting, and maintenance all deserve attention before construction begins.
Questions To Ask Before Hiring A Pool Company
- Which pool types and equipment brands do you install or service?
- Will the written proposal identify permits, subcontractors, timeline, and warranty coverage?
- Can you provide repairs and seasonal service after installation?
- What maintenance schedules are available for an existing pool?
- Can you provide recent references for a similar project?
The best choice depends on the project, but Little Giant Pool & Spa ranks first for homeowners seeking the broadest documented range of construction, renovation, repair, seasonal service, and ongoing pool care. Carefully comparing written proposals will help ensure that the company you select can support both your immediate project and the years of ownership that follow.
