Houston Fiberglass Pool Repair & Resurfacing 7-10 Day Install
From the estate pools of River Oaks and Memorial to the family backyards of Katy, Sugar Land, and The Woodlands, Houston pools fight a brutal combination — Beaumont Formation coastal clay that swells and shrinks with every storm-and-drought cycle, and a high Gulf Coast water table that pushes up under the shell.
Hexagon Fiberglass Pools specializes exclusively in fiberglass solutions engineered for Houston's expansive clay, high water table, and humid Gulf Coast climate. 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.

Complete fiberglass solutions for every pool type
Fiberglass Pool Resurfacing
Replace deteriorating plaster or marcite on your Houston pool with permanent fiberglass — eliminating the surface failures that Gulf Coast clay, a high water table, and humid heat cause on traditional materials.
Our fiberglass pool resurfacing in Houston bonds a permanent, non-porous shell over your existing surface — ending the Gulf Coast plaster-failure cycle for good.
- Permanent surface vs. recurring $6,000–$12,000 replastering
- Glass-smooth — never rough, stained, or algae-prone again
- Up to 45% reduction in chemical usage
- Algae-resistant non-porous surface for humid Gulf air
- Choice of 10-yr or 25-yr transferable warranty
Fiberglass Pool Conversion
Vinyl liner, gunite, concrete, or aging fiberglass — Hexagon converts all pool types to superior fiberglass without excavation, keeping your existing Houston pool structure.

Why Houston Pools Benefit from Fiberglass
Why Houston Pools Benefit from Fiberglass
Expansive Beaumont Clay
Houston sits on Beaumont Formation clay — among the most expansive soils in the country. It swells with Gulf rain and shrinks in drought, shifting pool shells and cracking rigid plaster and gunite season after season.
- Clay movement cracks rigid plaster and gunite repeatedly
- Fiberglass flexes with seasonal soil movement
- No cracking from expansive-clay shift
- Structural crack repair included in prep
Gulf Coast Groundwater
Houston's shallow water table and history of land subsidence put constant hydrostatic pressure under and against pool shells — the force that bulges walls and floats empty pools.
- High groundwater pushes up under the shell
- Never drain a Houston pool without a pro — it can pop
- Flexible fiberglass tolerates ground movement
- We relieve pressure and stabilize before any work
Humid Gulf Air & Algae
Houston's high humidity and warm Gulf air create relentless algae pressure on porous surfaces, driving up chemical use and cleaning all season long.
- Porous plaster harbors algae in humid conditions
- Non-porous fiberglass resists algae growth
- Up to 45% less chemical usage
- Glass-smooth surface stays cleaner

Pool conversion in Houston typically ranges from $8,000 to $20,000 depending on pool size, condition, and features — generally 40–60% less than full pool replacement while delivering superior durability. Because fiberglass eliminates the resurfacing cycle that Houston's clay and humidity force every few years, most homeowners save thousands over the life of the pool.

Yes — we serve Greater Houston and the surrounding Gulf Coast, from River Oaks, Memorial, and The Heights to Katy, Sugar Land, The Woodlands, Kingwood, Clear Lake, and Pearland. Call us at 972-789-2983 to confirm coverage for your specific address; same-week assessments are available.
Three Gulf Coast forces combine: Beaumont Formation clay — among the most expansive soils in the country — swells and shrinks with storms and drought, cracking rigid plaster and gunite; a high, shallow water table pushes hydrostatic pressure up under the shell; and humid air drives relentless algae pressure on porous surfaces. Fiberglass is non-porous and flexible, which is why it outlasts traditional surfaces here.
No — this is critical on the Gulf Coast. Houston's high water table means an empty pool can be pushed up, cracked, or even floated out of the ground by hydrostatic pressure, especially after rain. Never drain a Houston pool to inspect or clean it without a professional. We check the water table and manage pressure before any drain.
Yes. Unlike rigid plaster and gunite that crack as Beaumont clay swells and shrinks, both our HEXConvert™ and Fibre Tech™ fiberglass systems flex with the ground movement. We also address the root cause — drainage and, where needed, backfill stabilization — so the surface isn't simply re-stressed.
Fiberglass is well suited to Houston's flood-prone Gulf Coast. A non-porous fiberglass shell resists the water intrusion and contamination that damage porous surfaces during flooding, and its flexibility tolerates the ground movement that heavy rain events drive. After a major storm, we can assess and repair shells, fittings, and equipment.
Significantly. Houston's heat and humidity make algae a constant battle on porous plaster, which holds growth in its texture. Fiberglass is non-porous and glass-smooth, so algae has nothing to grip — most homeowners see noticeably lower chemical use and easier cleaning across the long Houston season.
Our industry-leading 25-year Fibre Tech™ material warranty covers the structural integrity of the fiberglass surface — protection against blistering, delamination, and osmosis — as well as color fading and surface deterioration. It's transferable to future owners, which adds documented resale value in Houston's active market. HEXConvert™ offers a comprehensive 10-year labor-and-material warranty. Full documentation is provided at completion.
Absolutely — fiberglass is ideal for saltwater pools. Unlike plaster and concrete that salt degrades over time, our non-porous fiberglass surface is completely salt-resistant and won't pit or break down. Many Houston homeowners upgrade to or keep a saltwater system during conversion for the lowest-maintenance result.
Most Houston conversions take 7–10 days: a controlled drain (with the water table managed), surface preparation and crack repair, multi-layer fiberglass application, a controlled cure, then refill and water-chemistry balancing. We keep a clean worksite and protect your landscaping throughout, and we provide HOA documentation where needed.
Our fiberglass systems offer a range of fade-resistant colors with a UV-stabilized gel coat that holds its appearance for decades. White and light blue are our standard finishes; other premium colors are available at an upcharge. We'll show you samples and help you choose a shade that complements your Houston home and outdoor living space.
A professionally installed fiberglass surface lasts for decades — far longer than the 5–7 years plaster gives you on the Gulf Coast. HEXConvert™ carries a 10-year comprehensive warranty and Fibre Tech™ a 25-year transferable material warranty, and both routinely outlast those terms with normal care. You end the replaster cycle instead of repeating it.
Yes. We repair gel-coat fading and oxidation, spider cracks, osmotic blisters, and structural cracks on fiberglass pools — color-matched so the repair is invisible under water. Most repairs finish in 3–5 days, and we diagnose the root cause (Beaumont clay movement or high-water-table pressure) so the fix lasts.
It depends on the damage: minor gel-coat touch-ups start around $800–$1,500, larger restorations run $3,000–$8,000, and complete refinishing $8,000–$15,000. Wall-bulge and floor stabilization are quoted per pool after inspection. You get a firm, itemized quote at the free assessment — and catching damage early is always cheaper than waiting.
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 at the Houston consultation and only recommend an upgrade — like a variable-speed pump — when it will genuinely save you money.
No — and that matters on the Gulf Coast. The entire conversion is performed from inside the pool, so there's no digging, no heavy equipment on your lawn, and no destabilizing the soil around a high-water-table pool. Decking, landscaping, and outdoor kitchens stay untouched.
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 Greater Houston's active market, a low-maintenance pool with warranty paperwork is a genuine selling point versus a pool due for another replaster.
Yes. We convert and refinish pools with attached spas, tanning ledges, benches, and water features, unifying the whole surface in one finish. These are included in the structural assessment so your quote covers the entire Houston pool, not just the main shell.
We serve Houston and all of Texas, with crews experienced in Gulf Coast clay and high-water-table conditions. Call 972-789-2983 to confirm scheduling for your address — the assessment is always free, and veterans receive a 5% discount applied at booking.
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.
