Why San Antonio Pools Benefit from Fiberglass
Traditional Pool Surfaces vs. Fiberglass Performance
Edwards Aquifer Minerals
San Antonio's exceptionally hard water contains high mineral concentrations that degrade traditional surfaces year after year.
- Minerals stain plaster and concrete rapidly
- Cannot penetrate non-porous fiberglass
- Eliminates the acid washing cycle entirely
- Fiberglass cleans easily — no staining
Extreme Thermal Cycles
South Texas heat and cold snap cycles create destructive thermal stress that rigid surfaces simply cannot handle.
- Expansion/contraction cracks plaster and concrete
- Fiberglass flexes with temperature changes
- Traditional surfaces deteriorate rapidly
- Fiberglass maintains integrity year after year
Expansive Clay Geology
Austin Chalk and Eagle Ford formations shift the ground seasonally — inflexible surfaces fracture under the movement.
- Ground movement cracks traditional pool surfaces
- Fiberglass accommodates soil movement without failure
- Concrete and plaster require constant repairs
- Minimal impact on properly installed fiberglass
March – October Pool Use
San Antonio's extended swimming season means more chemical exposure, more wear — and more savings with fiberglass over time.
- Extended chemical exposure degrades traditional surfaces
- Fiberglass maintains integrity under heavy use
- Plaster and concrete require frequent resurfacing
- Fiberglass delivers decades of low-maintenance performance

San Antonio Success Stories
Real Results from Your Neighbors
$40,000 saved versus pool replacement
Our 1987 gunite pool was quoted at $47,000 for complete replacement by 3 contractors. Hexagon's conversion cost $18,500 and looks better than new. We chose the HEXConvert™ system with 10-year comprehensive warranty. The smooth surface is amazing after 15 years of rough concrete. Two years later, our chemical costs dropped 60%.
Solved our recurring crack problem permanently
Living on limestone bedrock, our pool cracked every 18 months despite $15,000 in 'permanent' repairs over 8 years. Hexagon's engineering team addressed the root cause with flexible installation. Zero cracks after 3 years, even during the 2023 drought.
Professional service exceeded expectations
As a cardiologist, I appreciate attention to detail. Hexagon's process was methodical and thorough. They completed our conversion in 6 days despite hard water challenges. The team's knowledge of San Antonio's unique conditions showed in every aspect.
Preserved our 1920s pool's character
Our historic home's original pool needed careful restoration. Hexagon worked within preservation guidelines while modernizing the surface. The fiberglass maintains the vintage appearance while providing modern performance.

Calculate My SavingsFrequently Asked Fiberglass Pool Questions
Fiberglass resurfacing in San Antonio typically ranges from $12,000–$19,000 depending on pool size, condition, and system choice. HEXConvert™ and Fibre Tech™ both offer superior value compared to traditional replastering ($8,000–$12,000 every 5–7 years). Our fiberglass solutions eliminate recurring resurfacing costs, saving significantly over 20 years.
Properly installed fiberglass surfaces last decades. HEXConvert™ includes a 10-year comprehensive warranty covering both materials and labor. Fibre Tech™ provides a 25-year material warranty. Both systems are engineered to perform for the life of your pool when maintained properly, eliminating the traditional 7-year resurfacing cycle.
Yes. Hexagon specializes in fiberglass pool repairs including gel coat restoration, spider crack elimination, and osmotic blister repair. We can restore aging fiberglass pools or repair damage from improper maintenance. Most fiberglass repairs complete within 3–5 days and include warranty protection.
Fiberglass pool repair costs vary by scope. Minor gel coat repairs start around $800–$1,500. Comprehensive restoration ranges $3,000–$8,000. Complete refinishing runs $8,000–$15,000. Many repairs qualify for warranty coverage if we performed the original installation. Contact us for a detailed assessment.
San Antonio's hard water from the Edwards Aquifer contains high mineral concentrations that stain traditional plaster surfaces. Both HEXConvert™ and Fibre Tech™ fiberglass surfaces resist mineral staining and prevent calcium buildup. Our specialized startup procedures optimize water chemistry for local conditions, reducing maintenance requirements.
Yes. Unlike rigid plaster that cracks with soil expansion, both our HEXConvert™ and Fibre Tech™ fiberglass systems accommodate San Antonio's clay soil movement through flexible construction. Our local installations successfully withstand soil challenges, including projects completed during drought and flood cycles.
We maintain positive relationships with San Antonio-area HOAs and provide architectural compliance documentation. Our fiberglass installations meet or exceed aesthetic standards while offering superior performance. Most HOAs appreciate our solutions after seeing neighborhood results.
HEXConvert™ includes 10-year comprehensive coverage (labor and materials). Fibre Tech™ provides 25-year material warranty. Both systems are specifically engineered for South Texas conditions including UV exposure, thermal cycling, and soil movement. Our warranties transfer to new owners — a major selling point in San Antonio's active real estate market.
Yes. We schedule around weather patterns and continue preparation work during rain delays. Our crews understand local weather and plan accordingly. Most projects complete within 7–10 days despite occasional spring storms.
Absolutely. We offer multiple color options for both HEXConvert™ and Fibre Tech™ systems, including traditional plaster blue, modern grays, and custom colors. Many San Antonio clients choose surfaces that complement their limestone, brick, or stucco exteriors. We provide samples for approval before installation.
HEXConvert™ offers comprehensive 10-year labor and material coverage, ideal for homeowners wanting complete protection. Fibre Tech™ provides 25-year material warranty, perfect for long-term planning. Both deliver identical performance and smooth, maintenance-free surfaces. We'll help you choose based on your priorities during your consultation.
Usually, yes. Your pump, filter, and heater typically work fine with a converted pool, and fiberglass's smooth surface can let equipment run easier. We assess your system during the San Antonio consultation and only recommend an upgrade — like a variable-speed pump — when it will genuinely save you money.
Resurfacing preps and overcoats a surface that still has usable life left; conversion is a complete interior system change for a pool whose underlying surface (vinyl liner, failing plaster, repeatedly cracking gunite) has reached the end of its service. Both end with a permanent fiberglass interior — we recommend the right one for your San Antonio pool at the assessment.
Yes — it's one of our highest-value conversions. Instead of replacing a liner every 7–10 years, we prepare the existing shell and install a permanent fiberglass interior, ending the liner-replacement cycle entirely. San Antonio's hard Edwards Aquifer water and long season make that recurring liner cost especially worth eliminating.
Yes. We convert and refinish pools with attached spas, tanning ledges, benches, and water features — unifying the whole surface under one finish. These are included in the structural assessment so your quote covers the entire San Antonio pool, not just the main shell.
It's safe. We finish steps, benches, and standing areas with appropriate texture for sure footing while keeping the rest of the surface smooth and easy to clean — so it's comfortable to swim against and stable where you stand.
Yes. The non-porous surface resists the algae and Edwards Aquifer scale that plague porous plaster, so most San Antonio homeowners use far fewer chemicals, never acid-wash, and never resurface. Across the city's 8-month season, that adds up to real time and money saved every year.
No. The entire conversion is performed from inside the pool — no digging, no heavy equipment on your lawn, and no damage to decking, mature live oaks, or outdoor kitchens. San Antonio properties with custom outdoor living spaces present no complications.
It can. A smooth, modern, warrantied surface shows well to buyers, and the Fibre Tech™ 25-year warranty is transferable — a documented asset that follows the home. In San Antonio's active market, including the large JBSA and medical-center community, a low-maintenance pool with warranty paperwork is a real selling point.

HEXConvert™ Resurfacing is our proprietary fiberglass resurfacing system. We bond a multi-layer fiberglass-and-gelcoat surface over your existing concrete, gunite, or plaster shell to create one continuous, non-porous, factory-smooth finish. Unlike plaster — which has to be redone every 7–10 years — a HEXConvert™ surface is a one-time installation backed by a 10- or 25-year warranty.
Re-Gel is the gelcoat-renewal stage of the HEXConvert™ system. We apply a fresh, color-matched gelcoat over the fiberglass to restore the smooth, glossy finish and protect it against UV, pool chemicals, and everyday wear — bringing an existing fiberglass surface back to like-new condition without a full rebuild.
Fiberglass lasts 25+ years vs 7-10 for plaster, reduces chemical usage by 75%, prevents algae growth, and never needs acid washing.
Our 25-year warranty covers the fiberglass shell against structural defects, delamination, blistering, and fading. It's transferable to future homeowners.
Both deliver the same smooth, permanent fiberglass surface — the difference is the warranty. HEXConvert™ is our proprietary system with a 10-year comprehensive (labor and materials) warranty and the fastest install. Fibre Tech™ carries a 25-year transferable material warranty, ideal if you may sell since it follows the home. We'll help you choose at the consultation.
Yes! Pool conversion works excellently for old or damaged pools. In fact, conversion is often the best solution for aging pools with cracks, surface deterioration, or structural issues. Our Fibre Tech™ system bonds directly to your existing concrete/gunite structure and can bridge minor cracks while providing structural reinforcement. We've successfully converted pools that are 30+ years old. During your free consultation, we'll assess your pool's condition and recommend the best approach for your specific situation.
Yes! Our Fibre Tech™ technology is custom-molded to fit any pool shape and size, from standard rectangles to custom freeform designs.
Your pool will look better! You can choose from various colors and the smooth gel-coat surface is more attractive than weathered plaster.
Absolutely! Fiberglass is completely salt-resistant, unlike concrete which can deteriorate from salt exposure.
Usually no. Most existing equipment works perfectly with fiberglass. We'll assess during consultation and recommend upgrades only if beneficial.
