Fiberglass Pool Resurfacing in Round Rock — before and after

What Is Pool Resurfacing — and Why Does Your Round Rock Pool Need It?

Pool resurfacing removes or overcoats your pool's existing interior finish and applies a new, durable surface layer to the shell. In Round Rock, that surface degrades faster than the national average for three local reasons: the Balcones Escarpment substrate — Edwards limestone and caliche on the west, expansive Blackland Prairie clay on the east — moves the shell and cracks rigid finishes, hard Central Texas water from Lake Georgetown and Stillhouse Hollow deposits limestone-rich scale on porous plaster, and 100°F-plus summers drive sustained UV and chemical wear.

Left unaddressed, a failing surface gets progressively more expensive — rough plaster holds mineral deposits and demands more aggressive acid washing, while cracks let water migrate behind the shell where Round Rock's two-zone substrate compounds the damage. Resurfacing before the surface reaches failure is always cheaper than remediation after it.

Signs Your Round Rock Pool Needs Resurfacing

Rough or sandpaper texture on floor and walls
Persistent staining acid washing no longer removes
Visible cracks, chips, or delaminating patches
Chalky calcium deposits or efflorescence
Recurring algae despite correct chemistry
Fading, discoloration, or uneven finish color
Unexplained water loss (surface micro-leaks)
Surface age over 7 years on plaster or marcite

Pool Resurfacing Services in Round Rock, TX

Hexagon resurfaces every pool type found in Round Rock — from aging plaster gunite pools near Old Town to master-planned pools in Teravista and Forest Creek approaching their first replaster milestone. Every path ends the same way: a permanent fiberglass surface engineered for Williamson County conditions.

Most Common

Plaster & Marcite Resurfacing

The majority of Round Rock pools built before the 2010s have white plaster or marcite interiors that hard Central Texas water scales and substrate movement cracks. Hexagon removes the deteriorated layer, repairs limestone-settlement and clay-driven structural cracks in the gunite shell, and applies HEXConvert™ or Fibre Tech™ fiberglass directly to the prepared surface — ending the replaster cycle permanently.

Replastering eliminated — not deferred
Structural crack repair included in prep
Fiberglass bonds directly to gunite shell
Glass-smooth finish, never rough again

Growing Demand

Pebble & Aggregate Resurfacing

Pebble and aggregate finishes installed across Teravista and Forest Creek in the 2000s–2010s roughen under hard water within a decade, becoming abrasive and hard to balance. Fiberglass resurfacing over aggregate delivers a glass-smooth, chemically neutral surface without shell demolition.

Hard-water mineral embed in aggregate ended permanently
Applied over existing aggregate — no demolition
Chemical neutrality reduces balancing burden
Glass-smooth, algae-resistant replacement

Suburban

Vinyl Liner Pool Resurfacing

Vinyl liner pools in older Round Rock neighborhoods carry a recurring liner-replacement cost every 7–10 years, and substrate movement accelerates seam failure. Hexagon resurfaces vinyl liner pools with a permanent fiberglass interior — eliminating liner replacement and the substrate-driven shell movement at once.

Liner replacement cycle eliminated permanently
Substrate-driven shell movement addressed
Permanent non-porous surface over prepared shell
Handles any Round Rock pool shape

Why Fiberglass Resurfacing — Not Replaster, Pebble Tec, or Epoxy Paint

Round Rock homeowners are typically presented with four resurfacing options. Here is an honest comparison of how each performs against Balcones-edge substrate, hard Central Texas water, and 100°F-plus summers over a 20-year ownership horizon.

Surface Type	Lifespan	20-Yr Cost	Hard Water	Substrate Movement
White Plaster	5–7 yrs	$54k–$96k	Scales within months	Cracks with movement
Marcite	6–8 yrs	$48k–$80k	Stains & scales rapidly	Cracks with movement
Pebble / Aggregate	8–12 yrs	$40k–$64k	Roughens in hard water	Cracks with movement
Epoxy Paint	2–4 yrs	$60k–$90k+	Peels in Central Texas heat & UV	Delamination risk
✓ HEXConvert™ / Fibre Tech™ Fiberglass	20–30 yrs	$12k–$19k	Non-porous — no scale	Flexes — no cracking

Fiberglass Pool Conversion in Round Rock — before and after

What Is a Fiberglass Pool Conversion — and Is It Right for Your Round Rock Pool?

A conversion is a complete interior system change — transforming your pool from its current surface (vinyl liner, plaster, gunite, concrete) to a permanent, non-porous fiberglass shell. Unlike resurfacing, conversion is the right call when the underlying system has reached the end of its service: a vinyl pool on its second-plus liner, a gunite shell that cracks again after every limestone-settlement or clay-driven repair, or a maintenance bill that now rivals the one-time cost of a permanent fix.

Hexagon performs every Round Rock conversion without excavation — no disruption to decking, landscaping, or outdoor living space. The entire conversion is completed from inside the pool in 7–10 days.

You're a Conversion Candidate If…

Your vinyl liner has been replaced once or more
Your gunite or concrete pool cracks recur after repair
Annual maintenance exceeds $3,000 with no improvement
Your pool has multiple simultaneous failure types
You're preparing the property for sale
Your pool is 15+ years old with no system upgrade

Fiberglass Pool Conversion by Pool Type

Hexagon converts every pool type found in Round Rock. The method is tailored to the existing shell — but the outcome is always the same: a permanent, low-maintenance fiberglass interior with full warranty coverage.

Most Requested

Gunite & Shotcrete Conversion

Gunite is the most common pool type in Round Rock's established neighborhoods. On the western Balcones edge, limestone and caliche settlement opens structural cracks; in the eastern transition zone, expansive Blackland clay shifts the shell seasonally. Either way, the cracks return after every repair. Conversion ends the cycle with a flexible, non-porous fiberglass surface that accommodates the movement that makes rigid concrete crack.

Structural crack cycle ends permanently
Flexible fiberglass accommodates substrate movement
Applied directly to prepared gunite shell
Pool and spa unified under one surface

Highest ROI

Vinyl Liner Conversion

Vinyl liner pools carry a recurring replacement cost every 7–10 years, and Central Texas conditions push degradation to the shorter end. A conversion eliminates the cycle entirely — Hexagon prepares the existing shell, repairs underlying damage, and installs a permanent fiberglass interior.

Recurring liner-replacement cost eliminated
Underlying shell damage repaired first
No more wrinkling, fading, or tearing
Non-porous surface for the life of the pool

Full Upgrade

Concrete & Older Shells

Older concrete and block shells in Round Rock's mature neighborhoods are vulnerable to mortar degradation and water infiltration in moving substrate. Hexagon waterproofs and stabilizes the structure before applying fiberglass, creating a sealed, unified interior without full demolition.

Structure assessed and stabilized first
Water migration behind the shell stopped
Sealed, unified fiberglass interior
Viable alternative to demolition and rebuild

Premium Upgrade

Fiberglass-to-Fiberglass

An existing fiberglass pool with a failing original surface — blistering, spider cracks, oxidation — is a strong conversion candidate. Rather than patch a compromised shell, Hexagon removes the failed layer, inspects and repairs the structure, and applies a fresh system with full new warranty.

Failed gel coat fully removed
Structural shell inspection and repair
Full warranty — transfers at sale
Preferred over repeated patch repairs

Why Round Rock Homeowners Choose Conversion Over Continued Maintenance

The financial and practical case for conversion is clear when you compare the cumulative cost of maintaining a traditional surface against the one-time cost of a permanent fiberglass system.

No Excavation. No Disruption.

The entire conversion is performed from inside the pool. No digging, no equipment on your lawn, no damage to decking, irrigation, mature trees, or outdoor kitchen structures. Round Rock properties with custom outdoor living spaces, pergolas, and fencing present no complications — Hexagon never requires ground disturbance for a conversion project.

The 20-Year Financial Case

A Round Rock pool on a traditional plaster or vinyl liner cycle costs tens of thousands of dollars over 20 years in surface maintenance alone — accelerated by hard Central Texas water, Balcones-edge substrate movement, and the long Central Texas pool season. A one-time fiberglass conversion costs $8,000–$20,000 and requires no further surface work within the warranty period. The difference is the conversion's return on investment.

A Documented Round Rock Resale Asset

In Williamson County's active real estate market, a Fibre Tech™ 25-year transferable warranty is a documented asset that survives a sale and follows the property. For Teravista, Forest Creek, and Behrens Ranch homeowners with a resale horizon, a warranted fiberglass conversion is one of the higher-ROI pool improvements available — turning a maintenance liability into a selling point.

What Is Pool Gel Coat — and Why Does Your Round Rock Fiberglass Pool Need It?

Gel coat is the outermost layer of a fiberglass pool — the resin finish that provides color, gloss, chemical resistance, and UV protection. When a fiberglass pool looks faded, feels rough, or shows cracks or blisters, it's the gel coat that has degraded, not the structural shell beneath it.

Round Rock's climate accelerates that degradation: long, intense summer UV oxidizes the surface, hard limestone-rich water dulls the gloss and traps algae, and Balcones-edge ground movement stresses the shell into spider cracks at fittings and steps. Left unaddressed, degraded gel coat exposes the laminate beneath — turning a cosmetic issue into a structural one.

Signs Your Round Rock Pool Needs Gel Coat Repair

Faded, chalky, or dull finish
Spider cracks on floor, walls, or around fittings
Osmotic blisters — raised bubbles on the surface
Rough texture in previously smooth areas
Gel coat separating from the shell
Persistent staining despite correct chemistry
Patchy color across pool and spa
Pool 10+ years old with no gel-coat service

Pool Gel Coat Repair Services in Round Rock, TX

Hexagon diagnoses the root cause of every gel coat issue before beginning work — Central Texas UV, hard limestone-rich water, and Balcones-edge substrate movement each produce distinct failure patterns requiring different repair approaches. All work is color-matched to your existing finish or upgraded to a premium modern color.

Most Comprehensive

Full Gel Coat Restoration

When oxidation, fading, and minor surface damage are widespread across the pool, a full gel coat restoration is the most cost-effective approach. Hexagon mechanically prepares the entire surface, addresses all underlying defects, and applies a fresh, UV-stabilized gel coat layer across the pool and spa as a unified refinish. The result is a pool that looks, feels, and performs as it did when first installed — with a color-matched or upgraded finish carrying UV inhibitors engineered for Central Texas's long, hot summers.

Complete pool and spa surface unified under new coat
Mechanically prepared — not chemically stripped
UV inhibitors resist the long Central Texas summer
Choice of color match or premium color upgrade

Most Common in Round Rock

Oxidation & UV Fade Repair

Oxidation is the most common gel coat issue on Round Rock fiberglass pools — caused by sustained UV exposure breaking down the resin polymers in the gel coat surface. Across the long Central Texas pool season, the finish loses its gloss, turns chalky white or gray, and becomes increasingly porous, holding algae and resisting cleaning. Hexagon's oxidation treatment removes the degraded surface layer, restores chemical resistance and UV protection, and brings the original color back to a like-new standard without shell replacement.

Chalky, dull finish restored — not polished over
Porous oxidized layer mechanically removed
Algae resistance restored for the full pool season
Effective on all fiberglass pool colors and ages across Round Rock

Substrate Related

Spider Crack Repair

Spider cracks in fiberglass gel coat are a direct consequence of ground movement — and Round Rock's Balcones-edge geology produces it two ways. On the western limestone and caliche shelf, settlement opens cracks at stress points; in the eastern Blackland clay transition, seasonal shrink-swell cycles the shell. Spider cracks typically radiate from fittings, steps, corners, and floor areas. Hexagon repairs spider cracks by grinding each crack to sound material, filling and laminating the substrate, then applying a color-matched gel coat patch that is invisible under water.

Substrate movement identified as root cause — limestone settling vs clay shrink-swell
Each crack ground to sound substrate — not filled over
Structural laminate repaired beneath the gel coat
Color-matched finish — invisible under water

Hard-Water Related

Osmotic Blister Repair

Osmotic blistering occurs when water molecules penetrate a compromised gel coat and accumulate between the gel coat and the fiberglass laminate, forming raised bubbles on the pool surface. In Round Rock, hard limestone-rich municipal water carries a mineral load that, at low pH, accelerates the osmotic process. Hexagon repairs blisters by opening each blister, cleaning the underlying cavity, rebuilding the laminate substrate, and applying gel coat over the repaired area. Water chemistry guidance is provided to prevent recurrence.

Every blister opened, cleaned, and rebuilt — not flattened
Underlying laminate damage addressed before gel coat
Hard-water chemistry guidance provided
Prevents escalation to full delamination

Why Round Rock Homeowners Should Not Delay Gel Coat Repair

Gel coat issues follow a predictable escalation path. What begins as a cosmetic problem — fading, minor cracking — becomes a structural and financial problem if left unaddressed through another Central Texas pool season.

Cosmetic → Structural

Spider cracks left unfilled allow water to penetrate to the fiberglass laminate. Once water reaches the laminate under Round Rock's moving Balcones-edge substrate, hydrostatic pressure and seasonal movement cycles cause delamination — separating the gel coat from the shell in sheets. A small crack repair becomes a far larger delamination job within a few Central Texas seasons.

The Long Central Texas Pool Season

Round Rock pools see a long swim season under intense summer sun. Every month a pool sits with oxidized, cracked, or blistered gel coat is a month of accelerated UV and chemical damage to the structural laminate beneath. Addressing gel coat deterioration in the cooler off-season protects the full season ahead and avoids emergency repairs when temperatures peak in July and August.

Round Rock Resale Value

In Williamson County's active real estate market, a documented, warranted gel coat restoration signals a well-maintained pool to buyers. A pool in poor visible condition invites a price reduction or an inspection contingency; a restored, warranted surface protects the asking price and shortens time on market.

What to Expect: The Gel Coat Repair Process

Most Round Rock gel coat repair projects complete in 3–5 days. Full restorations on pools with integrated spas typically take 5–7 days. No excavation, no heavy equipment, no disruption to your outdoor living space.

Day 1

Assessment & Drain

Hexagon technician inspects the full pool and spa surface under water and dry conditions. Failure type, extent, and root cause confirmed. Pool drained and surface allowed to dry before work begins.

Days 2–3

Why Fiberglass Pool Repair in Round Rock Requires a Different Approach

Fiberglass repairs aren't interchangeable with plaster or concrete repairs — and Round Rock's conditions make the distinction critical. The dominant force on Round Rock pools is the Balcones-edge substrate: Edwards limestone and caliche settlement on the west, expansive Blackland Prairie clay shrink-swell on the east. Both concentrate stress at fittings, steps, and shell seams through Central Texas's wet-dry, occasional-freeze cycle.

Hexagon's repair process begins with a root-cause assessment, not just a visual inspection. We identify whether damage originates from limestone settlement, clay movement, water chemistry, or structural fatigue — and address the underlying cause before any surface repair. Every repair is color-matched and warranted.

Pool Problems That Need Immediate Attention

Visible cracks on floor, walls, or around fittings
Water loss beyond normal evaporation
Skimmer pulling air — cracked housing or neck
Return fittings loose, leaking, or separating
Step or bench delamination
Bowing or bulging walls (soil pressure)
Repeated algae despite correct chemistry
Equipment pad flooding — possible shell leak

Pool Repair Services in Round Rock, TX

From hairline gel coat cracks to structural shell repairs and full skimmer replacements, Hexagon handles every repair type found on Round Rock pools — root-cause first, warranty-backed, color-matched to your finish.

Most Requested — Balcones Substrate

Structural Crack Repair

Structural cracks in fiberglass pools are the direct result of ground movement — and Round Rock straddles two substrate zones. On the western Balcones edge, Edwards limestone and caliche settlement opens cracks at predictable stress points; in the eastern transition zone, expansive Blackland clay shrink-swell cycles load through the shell. Cracks typically appear on the floor above movement zones, around fittings under directional pressure, and at corners where geometry concentrates stress. Hexagon repairs structural cracks by exposing the outer shell face where necessary, applying fiberglass laminate to restore structural integrity, and finishing with a color-matched gel coat. The root cause — settlement, clay load, or drainage — is documented and addressed as part of the repair scope.

Substrate movement confirmed as root cause — limestone settling vs clay shrink-swell
Laminate repair restores structural shell integrity
Color-matched gel coat — invisible under water
Up to 5-year warranty on all structural crack repairs

Round Rock Most Common

Skimmer Repair & Replacement

Skimmer failure is one of the most common repair calls on Round Rock pools — and one of the most consequential if ignored. The skimmer housing is bonded to the pool shell at the waterline, a location that experiences the highest concentration of thermal cycling, substrate movement, and UV exposure. Central Texas's swing from occasional winter freezes to 100°F-plus summers creates continuous expansion and contraction stress at the skimmer-to-shell bond. Cracks at the skimmer neck or housing let water bypass the seal and migrate behind the shell, where it interacts with the substrate to create sustained hydrostatic pressure. Hexagon repairs cracked housings, replaces failed skimmer bodies, reseals skimmer-to-shell bonds, and installs upgraded units where the original fitting is beyond repair.

Cracked skimmer neck repaired or housing replaced
Skimmer-to-shell bond resealed — thermal and substrate movement are primary failure drivers
Upgraded skimmer units specified for the long Central Texas season
Repair stops mineral-laden water infiltration behind the shell face

Water Loss Related

Fitting & Return Line Leak Repair

Return fittings, main drain covers, light housings, and spa jets are all penetration points in the fiberglass shell — and each is a potential leak source as sealants age and substrate movement applies shear force to bonded fittings. Hard limestone-rich water deposits mineral scale at penetration points that can compromise the seal bond over time. Unexplained water loss is typically traced to one or more fitting penetrations before a shell crack is confirmed. Hexagon performs a systematic pressure test and dye test to locate all active leaks, then repairs or replaces the affected fittings and reseals the shell penetration to current standards.

Systematic pressure and dye test locates every active leak
Fitting replacements address long-season sealant degradation
Shell penetrations resealed — substrate movement shears original sealant bonds
Water loss confirmed resolved before pool is returned to service

Substrate & Thermal Cycling

Step, Bench & Ledge Repair

Steps, benches, tanning ledges, and spa walls are the structural elements most vulnerable to delamination and cracking on Round Rock pools. Differential settlement on the Balcones-edge limestone shelf and seasonal expansion in the eastern clay zone both create uneven support under horizontal surfaces — steps and ledges — causing separation between fiberglass laminate layers. Central Texas thermal cycling between occasional winter freezes and summer heat amplifies this stress at the bond line between horizontal and vertical shell sections. Pools with tanning ledges and integrated spas have more horizontal surface area exposed to these forces. Hexagon repairs delaminated steps and ledges by re-bonding the separated layers, applying structural reinforcement where needed, and finishing with a color-matched gel coat.

Delaminated layers re-bonded — not patched over
Substrate settlement and clay load assessed and documented
Structural reinforcement applied on high-stress surfaces
Spa, step, and ledge surfaces color-unified on completion

Repair or Replace? Hexagon's Honest Assessment

Not every repair is worth making — and not every damaged pool needs replacing. Hexagon provides an honest structural assessment of every Round Rock pool before quoting, with a clear recommendation based on what actually makes financial sense for the property.

When Repair Is the Right Call

Isolated structural cracks with no shell delamination, a single skimmer failure, fitting leaks on an otherwise sound shell, and step or ledge repairs on a pool with good underlying structure are all strong repair candidates. A targeted repair on a sound fiberglass shell typically extends pool life by 10–15 years at a fraction of resurfacing cost — particularly valuable across the long Central Texas pool season, where every additional year of service has clear dollar value.

When Resurfacing Makes More Sense

When a pool has multiple simultaneous failure types — cracks, blistering, oxidation, and fitting leaks together — the cumulative repair cost often approaches resurfacing cost. In those cases, Hexagon recommends resurfacing over piecemeal repair: one fixed price, one process, a new surface, and a full warranty rather than multiple partial warranties on individual repairs. For Round Rock pools with recurring crack cycles driven by Balcones-edge substrate, resurfacing with a fiberglass system permanently eliminates the cycle.

When the Shell Needs Replacing

Severe shell delamination, hydrostatic uplift — where the pool shell has floated due to groundwater pressure — or widespread structural failure from sustained substrate loading are cases where repair is not viable. Hexagon will tell you directly when this is the situation — and provide a full replacement or conversion quote rather than charge for repairs that will not hold under Round Rock's soil conditions.

What to Expect: The Pool Repair Process

Most pool repair projects in Round Rock complete in 3–5 days. Structural repairs involving excavation or skimmer replacement may extend to 7 days. No heavy equipment on your lawn — all work performed from pool deck level.

Day 1

Why Round Rock Pools Benefit from Fiberglass

Limestone & Caliche

Hill Country Rock Shelf

Western Round Rock straddles the Balcones Escarpment — Edwards limestone, caliche, and thin rocky soils. The namesake anvil-shaped round rock in Brushy Creek is the same limestone shelf your pool sits on. Stable rock, but settlement and rock-shelf movement stress rigid plaster shells over time.

Limestone rock-shelf settlement cracks rigid plaster
Limestone-rich water etches and scales porous surfaces
Fiberglass flexes with substrate movement — no cracking
Structural crack repair included in prep

Eastern Clay

Blackland Prairie Transition

Eastern Round Rock sits in the Williamson County transition zone, where the Hill Country limestone gives way to expansive Blackland Prairie clay. When that clay soil shifts with the wet-dry season, it can compromise a pool's structural integrity — a different failure pattern than the western rock zone.

Expansive clay expands when wet, contracts in drought
Seasonal clay movement cracks rigid gunite and plaster
Fiberglass accommodates the shrink-swell cycle
One surface handles both Round Rock soil zones

Hard Water

Central Texas Mineral Load

City of Round Rock municipal water — drawn from Lake Georgetown and Stillhouse Hollow via the Brazos River Authority — is hard Central Texas water. Limestone-rich water causes calcium buildup, scaling porous plaster and driving up the chemical and acid-washing burden.

Minerals stain and scale porous plaster
Non-porous fiberglass resists scale buildup
Up to 45% less chemical usage
No recurring acid-washing cycle

Frequently Asked Fiberglass Pool Questions

Most pool resurfacing projects in Round Rock take 7-10 days from start to finish. Our Fibre Tech™ fiberglass system installs quickly with minimal disruption to your North Austin area property.

Yes, Round Rock sits on limestone bedrock which can cause water chemistry challenges and surface etching in traditional plaster. Our fiberglass surface is non-porous and resists the mineral buildup common in this area.

Absolutely. Round Rock's intense summer heat can reach 100°F+. Our Fibre Tech™ gel coat is UV-resistant and engineered for Central Texas conditions. Unlike plaster that degrades in sunlight, fiberglass maintains its appearance for decades.

Yes, we regularly work in Round Rock communities like Teravista, Forest Creek, and Sun City. We coordinate with HOAs, follow community guidelines, and maintain professional standards on every project.

25-year manufacturer warranty on the fiberglass surface, plus 2-year workmanship warranty. This is the strongest warranty available for pool resurfacing in Round Rock.

While initial investment is higher, fiberglass eliminates the 5-7 year resurfacing cycle. Over 20 years, Round Rock homeowners save significantly while enjoying lower maintenance and superior durability.

Yes, we address all structural issues including leaks before installing fiberglass. Leak detection, crack repair, and shell reinforcement are part of our comprehensive resurfacing process.

We offer premium gel coat colors including sapphire blue, crystal white, and aquamarine. All finishes are UV-resistant and maintain their appearance for decades in Central Texas sun. White and light blue are our standard finishes; other premium colors are available at an upcharge.

Investment varies by pool size and condition. Most Round Rock projects range from $10,000-$22,000. 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.
