The Pool You Actually Want

You’re not looking for just any pool. You want something that fits your space, matches your vision, and actually gets used by your family for years to come.

That means proper excavation that won’t cause drainage headaches later. Quality construction that doesn’t crack or leak after the first winter. And a design process that listens to how you actually live, not what looks good in a brochure.

When your pool is done right, summer evenings become something you look forward to instead of another maintenance chore. Your kids have friends over more often. Your property value reflects the quality investment you made. And you don’t spend weekends dealing with repair calls that could have been avoided with better construction from the start.

Licensed Pool Contractors Old Mastic

We Build Pools That Last

JAS Aquatics has been building custom inground pools for Old Mastic homeowners who want it done right the first time. We’re licensed pool contractors who understand Long Island’s soil conditions, weather patterns, and local building requirements.

Every pool we build starts with proper permits and follows New York State construction standards. We’re insured, local, and accountable to the community where we work and live.

You’ll find our completed projects throughout Old Mastic and surrounding areas. Homeowners choose us because we show up when we say we will, build what we promise, and stand behind our work long after the project is finished.

Pool Installation Process Old Mastic

From Design to First Swim

Your pool project starts with an on-site consultation where we measure your space, discuss your vision, and explain what’s possible within your budget. We handle all permit applications and ensure your design meets local building codes before any digging begins.

Excavation comes next, and this is where Long Island experience matters. We understand the sandy soil conditions and drainage considerations specific to Old Mastic properties. Proper excavation prevents the structural and water issues that cause expensive problems later.

Construction follows our proven process: steel reinforcement, concrete shell, plumbing and electrical rough-in, then finishing work including coping, decking, and any water features. We coordinate inspections at each phase and keep you updated on progress throughout the project.

Your pool is ready for water and final startup once all systems are tested and approved. We walk you through basic maintenance and provide the information you need to enjoy your new pool safely.

Residential Pool Building Services

Complete Pool Construction Under One Roof

Our pool construction services cover everything from initial design through final startup. You work with one licensed contractor instead of coordinating multiple subcontractors who may not communicate well with each other.

Excavation and site preparation account for soil conditions and proper drainage around your pool. We install the steel reinforcement and pour the concrete shell that forms the foundation of your pool structure. All plumbing and electrical work meets current codes and passes required inspections.

Finishing work includes your choice of coping materials, decking options, and any water features or lighting you want incorporated. We can build standard rectangular pools, custom shapes that fit unusual spaces, or elaborate designs with multiple levels and integrated spas.

Every project includes cleanup of your property and restoration of landscaping areas affected by construction. Your pool comes with startup service and basic maintenance instruction so you know how to keep it running properly.

Most residential pool projects in Old Mastic take 4-8 weeks from excavation to completion, depending on size, complexity, and weather conditions. Simple rectangular pools with basic decking finish faster than custom shapes with elaborate water features. We provide a realistic timeline during your consultation based on your specific design. Permit approval can add 2-3 weeks to the front end, but we handle that process while finalizing your construction details. Weather delays are more common in spring and fall, which is why most homeowners prefer summer construction when Long Island conditions are most predictable.
Yes, inground pools in Old Mastic require building permits from Suffolk County and must meet specific setback requirements from property lines and structures. Pool electrical work requires separate electrical permits and inspections by licensed electricians. We handle all permit applications as part of our service because we know the local requirements and inspection process. Attempting to build without proper permits creates legal problems when you sell your home and may require expensive corrections later. Some homeowner associations have additional approval requirements beyond county permits, so we check those restrictions during the initial consultation.
Long Island’s sandy soil drains quickly but can shift during excavation if not properly managed. This creates challenges with maintaining excavation walls and ensuring proper compaction around pool structures. Groundwater levels vary significantly across Old Mastic, and some areas require dewatering systems during construction. Experienced local contractors understand these conditions and plan accordingly. Poor excavation techniques can lead to settling, cracking, or drainage problems that are expensive to fix after your pool is completed. We use proper shoring and compaction methods specific to Long Island soil conditions.
Custom inground pools in Old Mastic typically range from $50,000 to $120,000 depending on size, shape, features, and site conditions. Basic rectangular pools with standard decking start at the lower end, while elaborate custom designs with water features, lighting, and premium materials cost more. Difficult excavation conditions, extensive utility relocations, or complex permits can affect pricing. We provide detailed written estimates after evaluating your specific site and discussing your preferences. Financing options are available for qualified homeowners. The key is getting accurate pricing upfront so you can make informed decisions about features and materials within your budget.
New pool owners need to understand basic water chemistry, filtration system operation, and seasonal maintenance requirements. We provide startup service and basic instruction when your pool is completed. Daily maintenance involves skimming debris and checking chemical levels, which takes 10-15 minutes during swimming season. Weekly tasks include vacuuming, brushing walls, and testing water balance. Most homeowners can handle routine maintenance themselves or hire local pool service companies for weekly cleaning. Equipment like pumps and heaters require periodic professional service. Proper maintenance from the beginning prevents expensive problems and keeps your pool safe and enjoyable for years.
Yes, we maintain all required New York State contractor licenses and carry comprehensive liability insurance for pool construction projects. Our licenses cover excavation, concrete work, and pool installation throughout Suffolk County including Old Mastic. Insurance protects both our workers and your property during construction. We provide proof of insurance before starting any project and ensure all subcontractors we work with maintain proper coverage. Licensed contractors follow building codes, obtain proper permits, and are accountable for their work. Unlicensed contractors may offer lower prices but create legal and financial risks that cost much more than any initial savings.
