Fiberglass Pool Resurfacing in Lewisville — before and after

What Is Pool Resurfacing — and Why Does Your Lewisville 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 Lewisville, that surface degrades faster than the national average for several local reasons: Eastern Cross Timbers soils — sandy loam over expansive clay — shift the shell seasonally and crack rigid finishes, Upper Trinity Regional Water District hard water deposits scale on porous plaster, Lewisville Lake humidity accelerates algae growth, and a long, hot pool season with 100°F-plus summers drives 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 the shrink-swell clay zones compound the damage. Resurfacing before the surface reaches failure is always cheaper than remediation after it.

Signs Your Lewisville 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 Lewisville, TX

Hexagon resurfaces every pool type found in Lewisville — from aging plaster gunite pools in Old Town to vinyl-liner pools in established Denton County neighborhoods. Every path ends the same way: a permanent fiberglass surface engineered for Cross Timbers and lakeside conditions.

Most Common

Plaster & Marcite Resurfacing

The majority of Lewisville pools built before the 2010s have white plaster or marcite interiors that UTRWD hard water scales and Cross Timbers clay-zone movement cracks. Hexagon removes the deteriorated layer, repairs 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 Castle Hills and Vista Ridge 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

Established Community

Vinyl Liner Pool Resurfacing

Vinyl liner pools in Lewisville's established neighborhoods carry a recurring liner-replacement cost every 7–10 years, and Cross Timbers clay-zone movement accelerates seam failure. Hexagon resurfaces vinyl liner pools with a permanent fiberglass interior — eliminating liner replacement and the clay-driven shell movement at once.

Liner replacement cycle eliminated permanently
Clay-driven shell movement addressed

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

Lewisville homeowners are typically presented with four resurfacing options. Here is an honest comparison of how each performs against Cross Timbers clay zones, UTRWD hard water, Lewisville Lake humidity, and North Texas heat-and-freeze over a 20-year ownership horizon.

Surface Type	Lifespan	20-Yr Cost	UTRWD Hard Water	Cross Timbers Clay
White Plaster	5–7 yrs	$54k–$96k	Scales within months	Cracks with clay shift
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 North 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 Lewisville — before and after

What Is a Fiberglass Pool Conversion — and Is It Right for Your Lewisville 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 clay-driven repair, or a maintenance bill that now rivals the one-time cost of a permanent fix.

Hexagon performs every Lewisville 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 Lewisville. 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 Lewisville's established neighborhoods. Cross Timbers clay zones cause the shell to develop structural cracks that return after every repair as the ground shifts seasonally. Conversion ends the cycle with a flexible, non-porous fiberglass surface that accommodates the soil movement that makes rigid concrete crack.

Structural crack cycle ends permanently
Flexible fiberglass accommodates clay 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 North 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 Lewisville's mature neighborhoods are vulnerable to mortar degradation and water infiltration in clay soil. 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 Lewisville 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. Lewisville 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 Lewisville pool on a traditional plaster or vinyl liner cycle costs tens of thousands of dollars over 20 years in surface maintenance alone — accelerated by UTRWD hard water, Cross Timbers clay-zone movement, Lewisville Lake humidity, and the long North 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 Lewisville Resale Asset

In Denton 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 Castle Hills, Vista Ridge, and lakeside 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 Lewisville 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.

Lewisville's climate accelerates that degradation: long, intense summer UV oxidizes the surface, UTRWD hard water dulls the gloss and traps algae, Lewisville Lake humidity feeds mineral buildup, and Cross Timbers clay-zone 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 Lewisville 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 Lewisville, TX

Hexagon diagnoses the root cause of every gel coat issue before beginning work — North Texas UV, UTRWD hard water, Lewisville Lake humidity, and Cross Timbers clay-zone 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 North Texas's long, hot summers.

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

Most Common in Lewisville

Oxidation & UV Fade Repair

Oxidation is the most common gel coat issue on Lewisville fiberglass pools — caused by sustained UV exposure breaking down the resin polymers in the gel coat surface. Across the long North 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 Lewisville

Cross Timbers Clay Related

Spider Crack Repair

Spider cracks in fiberglass gel coat are a direct consequence of ground movement — and Lewisville's Eastern Cross Timbers soils carry expansive-clay zones that produce seasonal soil movement, stressing pool shells year after year. Spider cracks typically radiate from stress points: fittings, steps, corners, and floor areas. The shrink-swell clay expands when wet and contracts in summer drought and winter freeze, cycling stress through the shell. 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.

Cross Timbers clay-zone soil movement identified as root cause
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 Lewisville, UTRWD-supplied hard 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
UTRWD hard-water chemistry guidance provided
Prevents escalation to full delamination

Why Lewisville 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 North Texas pool season.

Cosmetic → Structural

Spider cracks left unfilled allow water to penetrate to the fiberglass laminate. Once water reaches the laminate under the Cross Timbers' shrink-swell clay conditions, freeze-thaw and hydrostatic pressure 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 North Texas seasons.

The Long North Texas Pool Season

North Texas 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.

Lewisville Resale Value

In Denton 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 Lewisville 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

Why Fiberglass Pool Repair in Lewisville Requires a Different Approach

Fiberglass repairs aren't interchangeable with plaster or concrete repairs — and Lewisville's conditions make the distinction critical. The dominant force on Lewisville pools is the Eastern Cross Timbers' expansive-clay zones — sandy loam over clay — which expand and contract with North Texas's wet-dry, freeze-thaw cycle and concentrate stress at fittings, steps, and shell seams. Lewisville Lake humidity adds a constant moisture load on top of it.

Hexagon's repair process begins with a root-cause assessment, not just a visual inspection. We identify whether damage originates from soil 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 Lewisville, TX

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

Most Requested — Cross Timbers Clay

Structural Crack Repair

Structural cracks in fiberglass pools are the direct result of ground movement — and Lewisville's Eastern Cross Timbers soils carry expansive-clay zones among the more active shrink-swell areas in North Texas. Cracks typically appear on the pool floor above clay expansion zones, around fittings under directional soil pressure, and at corners where shell geometry concentrates stress. The wet-dry, freeze-thaw cycle cycles load through the shell year after year. 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 — soil load or drainage — is documented and addressed as part of the repair scope.

Laminate repair restores structural shell integrity
Color-matched gel coat — invisible under water
Up to 5-year warranty on all structural crack repairs

Lewisville Most Common

Skimmer Repair & Replacement

Skimmer failure is one of the most common repair calls on Lewisville 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, clay movement, and UV exposure. North Texas's swing from winter freezes to 100°F+ 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 clay zones 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 clay movement are primary failure drivers
Upgraded skimmer units specified for the long North 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 clay soil movement applies shear force to bonded fittings. UTRWD hard 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 — clay movement shears original sealant bonds
Water loss confirmed resolved before pool is returned to service

Clay & Thermal Cycling

Step, Bench & Ledge Repair

Steps, benches, tanning ledges, and spa walls are the structural elements most vulnerable to delamination and cracking on Lewisville pools. Differential soil settlement on the Cross Timbers clay zones creates uneven support under horizontal surfaces — steps and ledges — causing separation between fiberglass laminate layers. North Texas thermal cycling between 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
Clay settlement 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 Lewisville 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 North 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 Lewisville pools with recurring crack cycles driven by Cross Timbers clay zones, 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 clay 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 Lewisville's soil conditions.

What to Expect: The Pool Repair Process

Most pool repair projects in Lewisville 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.

Why Lewisville Pools Benefit from Fiberglass

Cross Timbers Soil

Sandy Loam Over Expansive Clay

Lewisville sits in the Eastern Cross Timbers near the lake — a transitional mix of sandy loam over expansive clay. The clay zones expand when wet and contract in drought, shifting pool shells season after season.

Clay-zone 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

Hard Water

UTRWD Mineral Load

City of Lewisville municipal water comes from the Upper Trinity Regional Water District drawing on Lewisville Lake — hard North Texas water that deposits scale on porous plaster and drives 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

Lakeside Humidity

Lewisville Lake Moisture

On the south shore of Lewisville Lake, Lewisville's lakeside humidity accelerates algae growth and mineral buildup on porous plaster.

Lakeside humidity feeds algae on porous surfaces
Non-porous fiberglass resists algae and mineral buildup
Glass-smooth surface gives algae nothing to grip
Ideal for Lewisville Lake area pools

Heat & Freeze

100°F Summers, Winter Freezes

North Texas swings from 100°F+ summers to 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 UV fading
Flexes through freeze-thaw without cracking
Holds up across the long North Texas pool season

Result: For Lewisville pools, fiberglass isn't a premium upgrade — it's the only surface that survives Cross Timbers soils, UTRWD hard water, Lewisville Lake humidity, and North Texas heat-and-freeze year after year.

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.
