Marshall Pool Resurfacing & Fiberglass Conversion 7-10 Day Install
From the historic homes around Courthouse Square to the rural acreage out on the FM roads, Marshall pools fight the same East Texas enemies — Piney Woods humidity, sandy and acidic forest soils that shift with the season, and a high water table near the bayous and area lakes that traditional plaster and gunite were never built for.

Why Marshall Pools Benefit from Fiberglass
Why Marshall Pools Benefit from Fiberglass
Sandy, Acidic Forest Soils
Marshall sits in the East Texas Piney Woods on sandy loam and acidic, sandy forest soils over the Wilcox and Carrizo sands — ground that shifts and settles unevenly with the season and works rigid pool shells loose over time.
- Uneven settlement cracks rigid plaster and gunite
- Fiberglass flexes with seasonal soil movement
- Non-porous surface unaffected by acidic soils
- Structural crack repair included in prep
High Humidity & Water Table
High rainfall and humidity — plus a high water table near the bayous and area lakes — push moisture against the shell year-round, feeding algae on porous plaster and driving hydrostatic pressure beneath the pool.
- Porous plaster holds algae in the humidity
- Non-porous fiberglass resists algae and staining
- Up to 45% less chemical usage
- Drainage and water-table conditions documented in prep
Hard East Texas Water
Marshall is served by City of Marshall municipal surface water drawn from the Sabine River and area lakes — hard East Texas water that deposits scale on porous plaster and adds to 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

Pool conversion costs in Marshall typically range from $8,000 to $20,000 depending on pool size, condition, and features. This is 40-60% less than complete pool replacement while providing superior durability. Our fiberglass conversion eliminates the need for resurfacing every 7 years, saving you thousands in long-term maintenance. Contact us for a free, no-obligation quote specific to your Marshall pool.
Yes! We serve all Marshall neighborhoods and surrounding areas. Our team is based in North Texas and provides same-day consultations throughout the region. Whether you're in the heart of Marshall or the surrounding suburbs, we've got you covered. Call us at 972-789-2983 to confirm coverage for your specific address.
Fiberglass provides significant long-term savings compared to traditional concrete/plaster pools. Traditional surfaces need resurfacing every 5-7 years at $6,000-$12,000 each time. Over 25 years, that's $25,000-$60,000+ in resurfacing costs alone. Our fiberglass conversion comes with a 25-year warranty and eliminates this recurring expense. You'll also save 70% on chemical costs, reduce water usage, and spend less time on maintenance. Most Marshall homeowners see ROI within 5-7 years.
Yes! We offer flexible financing options to make your pool conversion affordable. Our financing partners provide competitive rates with terms ranging from 12 to 84 months, allowing you to spread the investment over time while immediately enjoying a maintenance-free pool. Many Marshall homeowners find that their monthly financing payment is less than what they were spending on pool maintenance and chemicals. Contact us to discuss financing options that fit your budget.
Our Fibre Tech™ fiberglass system offers a wide range of beautiful, fade-resistant colors including Caribbean Blue, Reef Blue, Aquamarine, Lagoon Blue, Ocean Blue, and Pearl White. Each color features a UV-resistant gel coat that maintains its vibrant appearance for decades—unlike traditional plaster that fades and chalks within a few years. During your consultation, we'll show you color samples and help you choose the perfect shade to complement your Marshall backyard and home aesthetic. White and light blue are our standard finishes; other premium colors are available at an upcharge.
Our industry-leading 25-year manufacturer warranty covers structural integrity of the fiberglass surface, including protection against blistering, delamination, and osmosis. The warranty also covers color fading and surface deterioration. Unlike traditional plaster warranties that only cover a few years, our fiberglass warranty provides true long-term protection. This transferable warranty can even increase your home's resale value. We'll provide complete warranty documentation at project completion.
Yes! Our custom fiberglass conversion system works for virtually any pool size, shape, or configuration. Whether you have a small geometric pool, large freeform design, kidney shape, or custom configuration with benches, steps, and water features, we can accommodate it. Each fiberglass installation is custom-fabricated to match your exact pool dimensions and features. We've successfully converted pools ranging from 300 to 50,000+ gallons in the Marshall area.
Absolutely! Fiberglass is actually the ideal surface for saltwater pools. Unlike plaster and concrete that deteriorate rapidly from salt exposure, our non-porous fiberglass surface is completely resistant to salt corrosion. The smooth gel coat won't break down or pit like traditional surfaces, and you'll experience even better water chemistry with less equipment wear. Many Marshall homeowners choose to upgrade to saltwater systems during their fiberglass conversion for the ultimate low-maintenance pool experience.
The fiberglass conversion process is straightforward and typically takes 7-10 days. First, we drain your pool and prepare the existing surface by removing any loose material and repairing structural issues. Next, we take precise measurements and custom-fabricate your fiberglass shell. Once ready, we install the fiberglass lining, ensuring perfect bonding to your existing structure. After curing, we install new fittings, fill the pool, and balance the water chemistry. Throughout the process, we maintain a clean worksite and keep you informed of progress. Most Marshall pools are ready to enjoy within two weeks of starting.
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.
