You’re not just adding water to your yard. You’re creating the place your family actually wants to be on summer weekends instead of fighting traffic to the beach. You’re building the backdrop for birthdays, barbecues, and those random Tuesday nights when the kids just want to cool off.
A custom in-ground pool in Islip, NY changes how you use your property. It turns your backyard into the spot everyone gravitates toward. No more packing the car, no more paying beach parking, no more leaving early because someone’s tired.
And if you’re thinking about resale down the road, you’re looking at a potential property value increase between 8-15%. That’s not a guarantee, but it’s real data from the National Association of Realtors. The right pool, installed correctly, makes your home more desirable to the next buyer.
We’ve been building complete backyard poolscapes across Suffolk County and Nassau County for years. We’ve seen what happens when contractors skip the engineering, ignore the water table, or lowball the estimate just to win the job. You end up with cracks, delays, and change orders that double your budget.
We handle the full scope: gunite pool installation, custom pool coping and tile, concrete pool surrounds, pool patio masonry, retaining walls, grading, and everything in between. If it’s part of your backyard transformation, we’re managing it. One crew, one timeline, one point of contact.
Islip sits right in the middle of Long Island’s unique geography. Depending on where your property is, we’re dealing with either high water tables near the South Shore or rocky soil closer to the North Shore. Both require different approaches, and we’ve handled them both hundreds of times.
First, we come out and assess your yard. Not just measurements—we’re looking at drainage, soil composition, setbacks, and access. We’ll tell you upfront if there’s a water table issue or if ledge rock is going to add time and cost. No surprises later.
Then we handle permits. Every town in Suffolk County and Nassau County has different setback rules, zoning requirements, and fees. We pull what’s needed, submit the engineering drawings, and deal with the back-and-forth so you don’t have to.
Once we break ground, you’ll see excavation, steel installation, plumbing, and electrical rough-ins. Then comes the gunite application—that’s the structural shell of your pool. After that cures, we move into tile, coping, decking, and any masonry work like patios, outdoor kitchens, or retaining walls.
The timeline depends on scope and weather, but you’re looking at roughly 8-12 weeks for a standard build. Larger projects with extensive hardscaping take longer. We’ll give you a realistic schedule during the estimate, not an optimistic one.
Ready to get started?
You’re getting the pool itself—custom-shaped gunite construction built to your specs. But the pool is only part of it. We’re also handling the coping (the edge around the pool), tile work, and the deck or patio surface. You can choose from pavers, bluestone, travertine, poured concrete, or flagstone depending on your style and budget.
If your yard has elevation changes, we’re building retaining walls and doing the grading to make everything level and functional. If you want an outdoor kitchen, fire pit, or seating walls, that’s part of the same project. We’re not subbing that out to another company—you’re working with one team the entire time.
For Islip homeowners, we also factor in local conditions. Homes closer to the Great South Bay or near the Fire Island inlet often deal with higher water tables, which means we’re installing dewatering systems during construction to keep the site stable. Homes farther north might hit bedrock, which requires different equipment and adds time. We price all of that into the estimate so you’re not getting hit with add-ons halfway through the job.
You’re looking at somewhere between $45,000 and $90,000 for most in-ground pool installations in Suffolk County, with the average landing around $66,000. That’s for a standard gunite pool with basic coping, tile, and a concrete or paver deck.
But that number moves depending on size, shape, depth, and what you’re adding around it. A simple rectangular pool with minimal hardscaping costs less than a freeform design with a spa, custom tile, travertine pavers, and an outdoor kitchen. Add-ons like heating systems, lighting, waterfalls, or automation can tack on another $10,000 to $25,000.
Then there’s your yard. If we’re dealing with high groundwater, rocky soil, or tough access, that affects the price. Same goes for permits—those run anywhere from $1,500 to $4,500 depending on your town. We’ll walk your property and give you a real number, not a range you can’t plan around.
Every town on Long Island has its own rules, and Islip is no exception. You need a building permit, and that requires a survey, engineered drawings, and sometimes a variance if your yard doesn’t meet setback requirements. Setbacks dictate how far the pool has to be from your property line, house, septic system, and any easements.
Most towns require at least 10 feet from the rear and side property lines, but it varies. If your lot is tight or irregularly shaped, you might need to apply for a variance, which adds time and cost. We handle all of that—pulling permits, submitting plans, and coordinating inspections.
The process usually takes 4-6 weeks depending on the town’s workload. We won’t start digging until everything’s approved. Skipping permits or trying to go around them isn’t worth it. You’ll get flagged during a resale inspection, and fixing it after the fact costs way more than doing it right the first time.
The South Shore of Long Island, including parts of Islip near the bay, has a high water table. That means groundwater sits close to the surface, and when you dig a big hole for a pool, it fills with water. You can’t pour gunite or set plumbing in a pit full of water, so we install a dewatering system.
That’s basically a pump setup that pulls groundwater out of the excavation site and keeps it dry while we work. We run it throughout construction until the pool shell is complete and backfilled. It’s a standard part of the process in these areas, and we factor the cost into your estimate.
If your property is farther inland or on higher ground, you might not need it. We’ll know after the site assessment. Either way, it’s not something we skip or hope for the best on. Water table issues cause major problems if ignored—cracked shells, shifting decks, and hydrostatic pressure that can literally pop your pool out of the ground.
Plan on 8-12 weeks from the day we break ground to the day you’re swimming. That’s assuming normal weather, no permit delays, and a straightforward build. Larger projects with extensive pool patio masonry in Suffolk County, custom features, or difficult site conditions can push that to 14-16 weeks.
The timeline breaks down like this: excavation and steel installation take about a week. Plumbing and electrical rough-ins take another few days. Gunite application happens in one day, but then it needs to cure for 7-10 days. After that, we’re doing tile, coping, and decking, which takes 2-4 weeks depending on the material and scope.
Weather’s the wildcard. Heavy rain or freezing temps can delay concrete work. We’ll give you a realistic schedule upfront and keep you updated if anything shifts. Rushing a pool build to hit an arbitrary deadline is how you end up with problems later. We’d rather take the extra week and do it right.
Gunite is sprayed concrete reinforced with steel rebar. It’s the most durable option and the only one that lets you fully customize the shape, depth, and features. You’re not limited to pre-made molds. That’s what we build, and it’s the standard for custom in-ground pools in Nassau County and Suffolk County.
Vinyl pools use a pre-fabricated liner installed over a frame. They’re cheaper upfront, but the liner needs replacing every 7-10 years at a cost of $4,000-$5,000. They’re also more prone to tears and don’t hold up as well in Long Island’s freeze-thaw cycles.
Fiberglass pools are pre-molded shells that get craned into your yard. They install faster, but you’re stuck with whatever shapes and sizes the manufacturer offers. They also don’t handle ground movement as well, which is a concern in areas with shifting soil or high water tables. Gunite costs more upfront, but it lasts 50+ years with proper maintenance and gives you full design control.
Yes, and we’d rather build it all at once than have you call someone else later. Adding a spa, outdoor kitchen, fire pit, or seating walls after the pool is done means tearing up the deck we just installed, re-grading, and dealing with mismatched materials. It’s more expensive and messier than doing it during the initial build.
We handle complete backyard poolscapes in Islip, NY, which means we’re designing the entire outdoor space as one cohesive project. That includes custom pool coping and tile in Nassau County, concrete pool surrounds in Suffolk County, pool retaining walls, grading, and any masonry features you want.
If you’re thinking about adding something but aren’t sure yet, tell us during the design phase. We can stub in plumbing and electrical for future features, or at least plan the layout so adding them later doesn’t require major demolition. But if you know you want it, build it now. You’ll save money and end up with a better-looking result.
