San Marcos Fiberglass Pool Repair & Resurfacing 7-10 Day Install

From the river neighborhoods below San Marcos Springs to the new Hill Country subdivisions climbing the Balcones Escarpment, Hays County pools fight the same enemy — faulted Edwards limestone bedrock that shifts beneath thin rocky soils and cracks rigid plaster and gunite, while mineral-rich Central Texas water scales every porous surface.

Hexagon Fiberglass Pools specializes exclusively in fiberglass solutions engineered for San Marcos's limestone terrain, hard Edwards Aquifer water, and Central Texas temperature swings. Choose our proprietary HEXConvert™ system with comprehensive 10-year labor and material warranty, or premium Fibre Tech™ technology with industry-leading 25-year transferable warranty.

  • Color-matched or upgrade to a new color
  • Restores UV protection and chemical resistance
  • Addresses spider cracks and blistering

Why San Marcos Pools Benefit from Fiberglass

Why San Marcos Pools Benefit from Fiberglass

Hard Water

Edwards Aquifer Minerals

San Marcos sits on the Edwards Aquifer, and its mineral-rich Central Texas water deposits calcium scale and etches porous plaster — the same spring water that feeds the San Marcos River.

  • Calcium buildup stains and scales porous plaster
  • Non-porous fiberglass resists mineral deposits
  • Up to 45% less chemical usage
  • No recurring acid-washing cycle
Limestone Base

Faulted Hill Country Bedrock

San Marcos sits on the Balcones Escarpment over faulted Edwards limestone with thin rocky soils. The rock shelf shifts and settles, cracking rigid plaster and gunite common in Hill Country pools.

  • Limestone settlement cracks rigid plaster and gunite
  • Fiberglass flexes with ground movement
  • No cracking from bedrock shift
  • Structural crack repair included in prep
Heat & Freeze

100°F Summers, Winter Freezes

Central Texas swings from 100°F+ San Marcos summers to occasional hard winter freezes. The expansion-and-contraction stress fractures rigid surfaces; fiberglass flexes with it.

  • Thermal cycling cracks plaster and concrete
  • Fiberglass gel coat resists intense Texas UV
  • Flexes through freeze-thaw without cracking
  • Holds up across the long Central Texas pool season

Frequently Asked Fiberglass Pool Questions

Most pool resurfacing projects in San Marcos take 7-10 days from start to finish. Our Fibre Tech™ fiberglass system installs quickly with minimal disruption to your Hill Country property.

Yes, San Marcos sits on the Edwards Aquifer with mineral-rich spring water. This can cause calcium buildup and etching in traditional plaster. Our non-porous fiberglass surface resists mineral deposits and staining.

Absolutely. San Marcos' limestone bedrock can shift, causing traditional plaster to crack. Our fiberglass flexes with ground movement, preventing the cracking common in Hill Country pools.

Yes, we regularly serve San Marcos and the Hill Country. The drive from our service area allows us to provide the same premium service and warranty coverage that Austin-area customers receive.

25-year manufacturer warranty on the fiberglass surface, plus 2-year workmanship warranty. This provides long-term protection for your San Marcos pool investment.

While initial investment is higher, fiberglass eliminates the 5-7 year resurfacing cycle. Over 20 years, San Marcos homeowners save significantly while enjoying lower maintenance costs.

Yes, we work throughout San Marcos including properties near the river and springs. Our fiberglass surface is ideal for areas with high water tables and mineral-rich groundwater.

Popular choices include sapphire blue (complements Hill Country views), crystal white, and aquamarine. All finishes are UV-resistant and maintain their appearance for decades. White and light blue are our standard finishes; other premium colors are available at an upcharge.

Investment varies by pool size and condition. Most San Marcos projects range from $9,000-$20,000. Call (972) 789-2983 for a free assessment and detailed quote.

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.
