Now, we’re proud to offer premium fiberglass swimming pools by Pentarm Pools, the perfect solution for Long Island families looking to create their dream backyard retreat without the lengthy installation and maintenance headaches of traditional concrete pools.
Fiberglass pools are specifically engineered to thrive in Long Island’s unique climate. Unlike concrete pools that can crack during our harsh freeze-thaw cycles, fiberglass pools feature a flexible, one-piece shell that expands and contracts with temperature changes. The non-porous gel coat surface resists algal growth even in our humid summers, so you’ll spend less time maintaining your pool and more time enjoying it with family and friends.

The Luxury of Acrylic Transparency
the smart choice for Long Island homeowners
What makes fiberglass swimming pools the smart choice for Long Island homeowners? Installation takes just two to three weeks from excavation to your first swim, compared to three to six months for concrete pools. The smooth, factory-finished surface requires fewer chemicals, costs less to heat, and never needs resurfacing. Whether you’re in the Hamptons, Huntington, or anywhere across Long Island, we deliver turn-key pool installations that transform your outdoor space into a luxury resort experience.
Why Fiberglass Swimming Pools Are Perfect for Long Island Homeowners
Quick Installation – Swim Sooner
Your fiberglass pool arrives factory-built and ready to install. Our expert team completes most installations in just two to three weeks, compared to months for concrete pools. That means minimal disruption to your property and maximum enjoyment of your investment. We handle excavation, delivery, installation, plumbing, electrical, and finishing work with precision and efficiency.
Built for Long Island Weather
Long Island’s climate demands durability. Fiberglass pools feature superior freeze-thaw resistance, withstanding harsh winters without cracking or structural damage. The flexible shell adapts to ground movement and temperature fluctuations. During humid summers, the smooth, non-porous surface naturally resists algae growth, keeping your pool crystal clear with less effort.
Low Maintenance, High Enjoyment
Fiberglass pools require 30 to 50 percent less chemicals than concrete pools thanks to their non-porous gel coat surface. The smooth finish prevents algae from taking hold and is gentle on swimmers’ skin. You’ll never need to resurface or repaint your pool. Simple weekly cleaning and basic chemical balancing keeps your pool pristine, giving you more time to relax and less time on maintenance.
Energy Efficient & Cost-Effective
The insulating properties of fiberglass significantly reduce heating costs compared to concrete pools. Long-term savings extend beyond energy bills with reduced chemical costs, no resurfacing expenses, and minimal repairs over decades of use. While the initial investment is competitive, fiberglass pools deliver exceptional lifetime value that concrete simply cannot match.
Beautiful, Modern Designs
Choose from an extensive selection of shapes, sizes, and stunning gel coat colors to complement your Long Island home. Built-in features like tanning ledges, beach entries, bench seating, and integrated steps create a custom look without additional construction. From contemporary geometric designs to classic freeform pools, we’ll help you select the perfect style for your backyard vision.
Exceptional Durability & Warranty
Fiberglass pools are built to last a lifetime. The factory-controlled manufacturing process ensures consistent quality and strength. Most manufacturers offer comprehensive warranties covering the pool shell for decades. Unlike concrete that requires acid washing and replastering every ten to fifteen years, your fiberglass pool maintains its beauty and integrity with minimal intervention.
