Pools made for Seguin living.
If you have been searching for the best custom pool builder in Seguin, TX — a luxury swimming pool builder and full-service pool contractor — you have found a local team. Seguin sits where the Hill Country meets the blackland prairie, and we build pools made for it. From Navarro and Mill Creek Crossing to the established neighborhoods along the Guadalupe, we design custom backyards shaded by Seguin's famous pecans.
Because we build across Guadalupe County, we know the clay soils here move differently than Hill Country limestone — and we engineer for it. Every pool is finished in durable PebbleTec and built on a structure designed for your exact lot.
Every Seguin pool we build is engineered to its exact lot and finished in durable PebbleTec, then backed by smart automation and equipment from trusted partners like Pentair and Jandy. The result is a resort-quality retreat designed for how Texas families actually live outdoors — and built to last through decades of seasons.
Built by two brothers and career firefighters, J. Oliver Pools brings the same integrity and attention to detail to every Seguin project. Most custom gunite pools we build start around $60,000, with mid‑range builds between $75,000 and $150,000 depending on size, finishes, and features.
Custom pools across Seguin & Guadalupe County.
Seguin blends historic in-town homes, growing subdivisions, and waterfront living along the Guadalupe River and Lake McQueeney. We design and build custom gunite pools throughout Guadalupe County and the communities below.
Navarro Estates
Established family neighborhoods with comfortable lots. Geometric pools with spas and tanning ledges are favorites here.
Mill Creek
A golf-course community with an active HOA. We design view-oriented pools and manage every submittal.
Lake McQueeney
Waterfront and near-water lots. We design pools that complement the lake setting and outdoor entertaining.
Starcke Park & River District
Homes near the Guadalupe River. We plan around grade and drainage for lasting riverfront pools.
Rio Vista & Cordova
Growing subdivisions on the edge of town. Family designs with shade and shallow lounging zones shine.
Seguin Acreage
Rural lots outside town where we build sprawling pools, spas, and full outdoor kitchens.
Engineered for Clay Soils
Seguin's blackland clay expands and contracts with the seasons. We run soil studies and reinforce every structure so your pool stays true for decades.
Built Around Mature Trees
Seguin's pecans and oaks are worth keeping. We design the pool and decking to protect root zones and shade where you want it.

Building a swimming pool in Seguin isn't the same as building one on flat, sandy ground. Get the engineering wrong and a pool can shift, crack, or settle; get it right — as we do on every build — and you have a structure that holds true for decades. Here is an honest look at what goes into a custom pool in our area, and why hiring a local builder protects your investment.
Blackland clay engineering
Seguin sits on expansive blackland clay that swells and shrinks with the seasons. We run soil studies and design a reinforced structure and decking so your pool stays true for decades.
Flat lots & waterfront
Many Seguin lots are flatter and family-sized, ideal for clean geometric pools, tanning ledges, and generous decking — and we build for the lake and river lots too.
Permits, HOA & engineering
We manage City of Seguin and Guadalupe County permits, stamped structural engineering, and HOA architectural approvals for communities like Navarro Estates, Mill Creek, and the Lake McQueeney communities. You never chase paperwork — it is part of the build.
Texas heat, sun & water
Long, hot summers shape smart design: efficient variable-speed pumps, optional heaters and chillers, generous shade and shelf seating, and PebbleTec finishes that hold up to UV and hard water year-round.
Transparent pricing, no surprises.
Every backyard is different, so every quote is built from your site, your design, and the features you want — never a templated number. As a guide, here is what custom gunite pool projects typically run in the Seguin market. For a deeper breakdown, read our 2026 custom pool cost guide, or explore pool financing options.

Figures are typical ranges for the Seguin area and include design, engineering, permitting, and PebbleTec finish. Final pricing depends on size, depth, access, soil, and selected features. We provide a clear, line-item proposal before any work begins.
From first sketch to first swim.
A Seguin pool typically takes eight to fourteen weeks of construction once permits and approvals are in hand, depending on size, weather, and features. Here is the path your project follows. See our full week-by-week pool build timeline.
Design & 3D rendering
We meet at your home, study the lot, and translate your vision into a photorealistic 3D design so you can see and refine your pool before a shovel touches the ground.
Engineering & permits
We finalize structural engineering, pull City of Seguin and Guadalupe County permits, and secure HOA approval — all handled by our team.
Excavation & gunite shell
We dig, set steel, run plumbing and electrical, and pneumatically place the gunite shell that gives your pool its permanent strength.
Tile, decking & features
Waterline tile, coping, decking, and water features go in, followed by your outdoor-living elements — kitchens, pergolas, and fire.
PebbleTec finish & startup
We apply your PebbleTec interior, fill the pool, balance the water, commission the automation, and walk you through ownership. Then you swim.
