Custom Gunite Pool Installation

Your Backyard Becomes the Destination

You’re not just getting a pool. You’re creating the space where your kids learn to swim, where summer barbecues happen, and where you unwind after long days.

Gunite construction means your pool can be any shape, any size, exactly where you want it on your property. No compromising because of pre-made molds or size limitations.

The concrete shell we build will outlast vinyl liners by decades. While your neighbors are replacing liners every 8-10 years, you’re enjoying the same solid structure that gets better with age. That’s the difference between building something right and building something cheap.

Central Islip Pool Contractors

We've Been Building Here Since Day One

JAS Aquatics has been serving Central Islip and Long Island families for years, and we understand what works in our soil conditions and climate. We’re not a franchise or a company that parachutes in from somewhere else.

Every gunite pool we build comes with the knowledge of local codes, proper drainage for Long Island properties, and the kind of attention you get when you’re working with people who live and work in your community.

You’ll work directly with our team from design through completion. No subcontractors you’ve never met showing up to work on your project.

Gunite Pool Construction Process

Here's Exactly What Happens Next

First, we’ll walk your property and discuss what you want. We measure, check utilities, and make sure your vision fits your space and budget before moving forward.

Once you approve the design, we handle permits and scheduling. Excavation typically takes 1-2 days, depending on your pool size and any access challenges with your property.

The gunite application is where your pool really takes shape. We spray the concrete mixture over rebar framework, creating the shell that will last decades. After curing, we install plumbing, electrical, and your chosen finishes.

The entire process usually takes 6-8 weeks from start to finish, weather permitting. We’ll keep you updated throughout so you know exactly where things stand.

Gunite Swimming Pool Features

What You Get With Gunite Construction

Gunite gives you design freedom that other pool types can’t match. Curved edges, integrated spas, beach entries, swim-up bars – if you can imagine it, we can build it.

The structural integrity means your pool can handle Long Island’s freeze-thaw cycles without cracking or shifting. The concrete shell bonds with rebar reinforcement to create something that’s built to last generations, not just seasons.

You’ll also have unlimited options for finishes. Plaster, aggregate, tile – whatever matches your home’s style and your family’s preferences. And unlike vinyl pools, you can change finishes down the road if you want a different look.

Most gunite pool installations in Central Islip take 6-8 weeks from excavation to completion, assuming normal weather conditions. The timeline can extend if we hit unexpected underground utilities, have extended rain delays, or if you choose complex custom features. We always provide a realistic timeline upfront and keep you updated if anything changes. The gunite application itself only takes one day, but proper curing time is essential for long-term durability.
Gunite is actually a type of concrete – specifically, concrete that’s applied pneumatically (sprayed) rather than poured. This application method allows us to create any shape and ensures better compaction around rebar and in tight corners. The end result is the same: a reinforced concrete shell. Some contractors use the terms interchangeably, but the gunite process typically produces a stronger, more consistent finish than traditional poured concrete methods.
Custom gunite pools in Central Islip typically range from $60,000 to $120,000, depending on size, features, and site conditions. Basic rectangular pools start at the lower end, while complex shapes with spas, waterfalls, and premium finishes reach the higher end. Your specific cost depends on excavation challenges, chosen finishes, and local permit requirements. We provide detailed written estimates so you know exactly what’s included before any work begins.
Properly built gunite pools don’t crack from freeze-thaw cycles when constructed correctly for Long Island conditions. The key is proper steel reinforcement, adequate concrete thickness, and correct winterization. We build our gunite pools with rebar spacing and concrete coverage designed for Northeast weather. The concrete itself is stronger than the ground around it, so seasonal ground movement doesn’t affect the pool structure. Proper closing and water level management prevent freeze damage to plumbing and surface finishes.
Yes, gunite construction actually works better in tight spaces than other pool types because we can customize the shape to fit your exact yard dimensions. We’ve built pools in backyards where other contractors said it couldn’t be done. The key is creative design and sometimes using smaller equipment for excavation. We’ll assess your property access, setback requirements, and utility locations to determine what’s possible. Even small gunite pools provide the same durability and customization options as larger installations.
Gunite pools require similar weekly maintenance to other pool types – skimming, chemical balancing, and cleaning. The difference is long-term maintenance costs. You won’t replace liners every decade like vinyl pools, and the concrete shell doesn’t deteriorate like fiberglass can over time. Plaster refinishing is typically needed every 10-15 years, but that’s a surface treatment, not structural work. The gunite shell itself should last 50+ years with normal care, making it the most cost-effective choice over time.
