Transform Your Backyard Into Paradise

You’ve been thinking about it for months, maybe years. That empty backyard space where you picture summer evenings, weekend gatherings, and kids learning to swim. A custom inground pool changes everything about how you use your outdoor space.

When it’s done right, your pool becomes the centerpiece of your property. Not just a hole filled with water, but a carefully designed space that fits your lifestyle and your land. You get mornings with coffee by the water, afternoons watching the kids play, and evenings that stretch longer because nobody wants to go inside.

The difference between a good pool and a great one comes down to understanding your property, your needs, and the unique challenges of building on Long Island. Soil conditions matter. Drainage matters. Design that works with your existing landscape matters. You deserve contractors who know these details inside and out.

Licensed Pool Contractors

Built on Long Island Expertise

JAS Aquatics has been building custom inground pools throughout Cold Spring Harbor and Long Island for years. We understand what it takes to create pools that last through harsh winters and look beautiful for decades.

Every project starts with understanding your property’s unique characteristics. Long Island soil conditions vary dramatically from one neighborhood to another. What works in one location might create problems in another. We bring that local knowledge to every job.

We’re licensed, insured, and focused on one thing: building pools the right way the first time. No shortcuts, no surprises, no wondering if your investment will hold up over time.

Pool Installation Process

From Design to First Dive

Your pool project starts with understanding exactly what you want and what your property can support. We walk your land, discuss your vision, and create a design that works with your space and budget.

Once you approve the design, we handle permits and scheduling. Long Island has specific requirements for pool construction, and navigating these regulations properly prevents delays and headaches later. You don’t have to worry about paperwork or compliance issues.

Excavation comes next, followed by the structural work that determines how well your pool will perform for years to come. We use quality materials and proven construction techniques that account for Long Island’s freeze-thaw cycles and soil conditions. Installation of plumbing, electrical, and finishing work follows a systematic approach that ensures everything works correctly from day one.

The final steps include decking, coping, and any custom features you’ve chosen. Before you take that first swim, we test every system and walk you through proper maintenance procedures.

Most custom inground pools in Cold Spring Harbor take 6-8 weeks from excavation to completion, depending on size, complexity, and weather conditions. The timeline includes excavation, structural work, plumbing and electrical installation, finishing, and decking. Weather delays can extend this timeline, especially during Long Island’s unpredictable spring and fall seasons. Permit approval adds 2-3 weeks before construction begins. More complex designs with extensive water features or challenging site conditions may require additional time. We provide realistic timelines upfront and keep you informed of progress throughout the project.
Cold Spring Harbor requires building permits for all inground pool construction, including structural, plumbing, and electrical permits. The Town of Huntington oversees permitting in this area, and requirements include detailed construction plans, property surveys, and compliance with setback regulations. Electrical work must be inspected at multiple stages, and final inspections are required before the pool can be filled and used. We handle all permit applications and scheduling of required inspections. We understand local requirements and maintain relationships with municipal offices to expedite the approval process whenever possible.
Custom inground pools in Cold Spring Harbor typically range from $50,000 to $100,000 or more, depending on size, design complexity, and site conditions. Basic rectangular pools with standard finishes start at the lower end of this range. Custom shapes, premium finishes, water features, and challenging excavation conditions increase costs. Long Island’s higher labor and material costs compared to other regions affect pricing. We provide detailed written estimates that break down all costs, so you understand exactly what you’re paying for. We discuss options that can adjust the project to fit your budget without compromising quality.
Long Island soil conditions vary significantly and directly impact pool construction methods and costs. Clay soils common in many areas require special excavation techniques and may need drainage systems to prevent hydrostatic pressure problems. Sandy soils drain well but may require different structural approaches. High water tables in some coastal areas require dewatering during construction and ongoing drainage solutions. We evaluate soil conditions before providing estimates and adjust construction methods accordingly. We understand which areas of Cold Spring Harbor present specific challenges and plan for these conditions from the start of your project.
We focus on pool construction rather than ongoing maintenance, but we provide comprehensive training on proper pool care and connect you with reliable local maintenance services. During your pool’s completion, we explain all equipment operation, chemical balancing basics, and seasonal care requirements specific to Long Island’s climate. We provide detailed documentation for all equipment and systems installed. For ongoing maintenance, we recommend trusted local pool service companies that understand the equipment and systems we install. This approach ensures you receive specialized expertise for both construction and long-term care.
We stand behind our construction work and address any issues that arise from workmanship or materials. We provide warranties on structural work and coordinate warranty service for equipment we install. Before final completion, we test all systems thoroughly and address any problems immediately. Most issues that occur after completion relate to equipment operation or maintenance rather than construction defects. We maintain relationships with equipment manufacturers and can quickly resolve warranty claims when needed. Clear documentation of all work performed and materials used ensures any future service needs can be handled efficiently by us or qualified service technicians.
