Fiberglass Pool Resurfacing in Alamo Heights — before and after

What Is Pool Resurfacing — and Why Does Your Alamo Heights 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 Alamo Heights, that surface degrades faster than the national average for three local reasons: the Edwards Plateau limestone and caliche soils underlying the 78209 enclave shift seasonally and crack rigid finishes, hard Edwards Aquifer water supplied by SAWS deposits scale on porous plaster, and a long, hot pool season with 100°F-plus summers drives sustained UV and chemical wear on premium finishes.

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 seasonal soil movement compounds the damage. On Alamo Heights' older estate pools, resurfacing before the surface reaches failure is always cheaper than remediation after it.

Signs Your Alamo Heights 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 Alamo Heights, TX

Hexagon resurfaces every pool type found in Alamo Heights — from aging plaster gunite estate pools in the Historic District to vinyl-liner pools near the Broadway and Austin Highway corridors. Every path ends the same way: a permanent fiberglass surface engineered for Balcones limestone conditions.

Most Common

Plaster & Marcite Resurfacing

The majority of Alamo Heights estate pools have white plaster or marcite interiors that SAWS hard water scales and limestone-soil movement cracks. Hexagon removes the deteriorated layer, repairs 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 Alamo Heights estates roughen under hard Edwards Aquifer 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

Corridor Pools

Vinyl Liner Pool Resurfacing

Vinyl liner pools near the Broadway and Austin Highway corridors carry a recurring liner-replacement cost every 7–10 years, and limestone-soil movement accelerates seam failure. Hexagon resurfaces vinyl liner pools with a permanent fiberglass interior — eliminating liner replacement and the soil-driven shell movement at once.

Liner replacement cycle eliminated permanently
Soil-driven shell movement addressed

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

Alamo Heights homeowners are typically presented with four resurfacing options. Here is an honest comparison of how each performs against Balcones limestone soils, Edwards Aquifer hard water, and South Texas heat-and-freeze over a 20-year ownership horizon.

Surface Type	Lifespan	20-Yr Cost	Edwards Aquifer	Limestone Soils
White Plaster	5–7 yrs	$54k–$96k	Scales within months	Cracks with soil 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 South 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 Alamo Heights — before and after

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

Hexagon performs every Alamo Heights conversion without excavation — no disruption to decking, mature live-oak canopy, 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 estate 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 Alamo Heights. 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 Alamo Heights' established estate neighborhoods. Balcones limestone and caliche soils 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 limestone-soil 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 South 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 Estate Shells

Older concrete and block shells in Alamo Heights' historic estate neighborhoods are vulnerable to mortar degradation and water infiltration in caliche soil. Hexagon waterproofs and stabilizes the structure before applying fiberglass, creating a sealed, unified interior without full demolition — preserving the estate's character.

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 Alamo Heights 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 live oaks, or outdoor kitchen structures. Alamo Heights estates 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

An Alamo Heights pool on a traditional plaster or vinyl liner cycle costs tens of thousands of dollars over 20 years in surface maintenance alone — accelerated by SAWS hard water, limestone-soil movement, and the long South 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 Alamo Heights Resale Asset

In the 78209 estate market, a Fibre Tech™ 25-year transferable warranty is a documented asset that survives a sale and follows the property. For Historic District and Olmos Park-adjacent owners 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 Alamo Heights 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.

Alamo Heights' climate accelerates that degradation: long, intense summer UV oxidizes the surface, SAWS hard water from the Edwards Aquifer dulls the gloss and traps algae, and Balcones limestone-soil 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 Alamo Heights 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 Alamo Heights, TX

Hexagon diagnoses the root cause of every gel coat issue before beginning work — South Texas UV, Edwards Aquifer hard water, and Balcones limestone-soil 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 South Texas's long, hot summers.

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

Most Common in Alamo Heights

Oxidation & UV Fade Repair

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

Limestone-Soil Related

Spider Crack Repair

Spider cracks in fiberglass gel coat are a direct consequence of ground movement — and Alamo Heights' Balcones limestone and caliche soils, with their clay pockets, produce seasonal soil movement that stresses pool shells year after year. Spider cracks typically radiate from stress points: fittings, steps, corners, and floor areas. The thin rocky soils over the Edwards Aquifer expand and contract through wet seasons and summer drought, 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.

Balcones limestone-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 Alamo Heights, SAWS-supplied Edwards Aquifer 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
SAWS hard-water chemistry guidance provided
Prevents escalation to full delamination

Why Alamo Heights 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 South Texas pool season.

Cosmetic → Structural

Spider cracks left unfilled allow water to penetrate to the fiberglass laminate. Once water reaches the laminate under Alamo Heights' limestone-soil 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 South Texas seasons.

The Long South Texas Pool Season

South 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.

Alamo Heights Resale Value

In the prestigious 78209 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 Alamo Heights 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

Surface Preparation

Defects addressed at substrate level — cracks ground and laminated, blisters opened and rebuilt, oxidized surface mechanically abraded. All preparation work is inspected before gel coat is applied.

Days 3–5

Why Fiberglass Pool Repair in Alamo Heights Requires a Different Approach

Fiberglass repairs aren't interchangeable with plaster or concrete repairs — and Alamo Heights' conditions make the distinction critical. The dominant forces on Alamo Heights pools are Edwards Plateau limestone and caliche soils, which create uneven pressure points beneath the shell as soil moisture redistributes, plus clay pockets that expand and contract with the wet-dry, freeze-thaw cycle and concentrate stress at fittings, steps, and shell seams.

Hexagon's repair process begins with a root-cause assessment, not just a visual inspection. We identify whether damage originates from soil movement, caliche pressure, 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 (caliche or soil pressure)
Repeated algae despite correct chemistry
Equipment pad flooding — possible shell leak

Pool Repair Services in Alamo Heights, TX

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

Most Requested — Limestone Soils

Structural Crack Repair

Structural cracks in fiberglass pools are the direct result of ground movement — and Alamo Heights' Edwards Plateau limestone, caliche, and clay-pocket soils produce active seasonal soil movement near the Balcones fault. Cracks typically appear on the pool floor above expansion zones, around fittings under directional soil pressure, and at corners where shell geometry concentrates stress. Caliche layers create uneven support that concentrates load as soil moisture changes. 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, caliche pressure, or drainage — is documented and addressed as part of the repair scope.

Balcones limestone and caliche soil movement confirmed as root cause
Laminate repair restores structural shell integrity
Color-matched gel coat — invisible under water
Up to 5-year warranty on all structural crack repairs

Alamo Heights Most Common

Skimmer Repair & Replacement

Skimmer failure is one of the most common repair calls on Alamo Heights 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, soil movement, and UV exposure. South 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 caliche and clay 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 soil movement are primary failure drivers
Upgraded skimmer units specified for the long South Texas season
Repair stops Edwards Aquifer 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 limestone-soil movement applies shear force to bonded fittings. SAWS Edwards Aquifer 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 — soil movement shears original sealant bonds
Water loss confirmed resolved before pool is returned to service

Caliche & Thermal Cycling

Step, Bench & Ledge Repair

Steps, benches, tanning ledges, and spa walls are the structural elements most vulnerable to delamination and cracking on Alamo Heights pools. Caliche layers create uneven support under horizontal surfaces — steps and ledges — causing separation between fiberglass laminate layers as differential soil settlement loads the shell unevenly. South Texas thermal cycling between winter freezes and summer heat amplifies this stress at the bond line between horizontal and vertical shell sections. Estate 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
Caliche pressure 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 Alamo Heights 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 South 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 Alamo Heights pools with recurring crack cycles driven by limestone soils, 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 caliche and soil 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 Alamo Heights' soil conditions.

What to Expect: The Pool Repair Process

Most pool repair projects in Alamo Heights 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

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.
