Custom In-Ground Pools in Nassau County

What You Actually Get When It's Done

You get a pool that doesn’t crack after the first winter. You get coping that stays level and doesn’t shift when the ground freezes. You get a patio that drains properly because we actually thought about Long Island’s clay soil before pouring anything.

This isn’t about the “pool of your dreams” or whatever else you’ve been reading. It’s about a structure that works, looks clean, and doesn’t become a maintenance nightmare two seasons in.

When we say complete backyard poolscapes in Nassau County, we mean the whole setup—pool shell, masonry surround, retaining walls if your yard slopes, proper grading so water moves away from your foundation, and coping that can handle freeze-thaw cycles without popping loose. You’re not coordinating five different contractors. You’re working with one team that knows how all the pieces fit together.

In-Ground Pool Builders in Franklin Square

We've Been Doing Masonry Work Here Since 2006

Ageless started as a masonry company in Franklin Square, NY, and we’ve been working on Long Island properties for nearly 20 years. We know the permit process in Nassau County. We know the soil conditions in Suffolk County. We know which materials hold up and which ones crack after one winter.

When you’re looking at in-ground pool builders in Suffolk County or Nassau County, you want someone who’s not going to disappear after the install. We’re local, licensed in both counties, and we’ve built our reputation on jobs that don’t fall apart. You’ll see our work around town—patios, pool surrounds, driveways—and it still looks right because it was done right.

Pool Installation Process in Franklin Square, NY

Here's How a Pool Actually Gets Built

First, we walk your property and talk through what’s realistic. If your yard has drainage issues or a steep grade, we’ll tell you before you spend a dime. Then we handle the permits—Nassau and Suffolk have different requirements, and we know what each building department wants to see.

Once permits clear, we excavate and prep the ground. If you need retaining walls or grading work, that happens now. Then the pool shell goes in—gunite for most custom builds—followed by plumbing and electrical rough-ins. After inspections pass, we install your coping and tile, then build out the patio or deck surround.

The whole process takes several weeks, weather depending. Spring installs are ideal if you want to swim by summer. We coordinate every trade, handle every inspection, and keep you updated at each stage. You’re not chasing down subcontractors or wondering who’s responsible when something doesn’t line up. That’s on us.

Pool Patio Masonry in Nassau County

What's Included in a Complete Pool Install

You’re getting the pool shell, but also the masonry work that makes it functional. That means custom pool coping and tile in Nassau County using materials that won’t crack in winter—travertine, bluestone, or concrete pavers depending on your budget and look. We install concrete pool surrounds in Suffolk County that are pitched correctly so water doesn’t pool near the house.

If your yard isn’t level, we build pool retaining walls and handle grading so the whole area is stable. A lot of Long Island properties have clay soil that shifts, and if the ground isn’t prepped right, you’ll see settling and cracks within a year. We also add stone pathways, sitting walls, or outdoor kitchen prep if you’re building out the full backyard.

This is what we mean by complete backyard poolscapes in Suffolk County and Nassau County. It’s not just dropping a pool in the ground. It’s making sure everything around it works together and lasts. The goal is a setup you’re not calling someone to fix every spring.

How much does it cost to install an in-ground pool in Franklin Square?

You’re looking at a wide range depending on size, materials, and site conditions. A basic vinyl liner pool starts around $25,000 to $65,000 installed. Gunite pools with custom shapes and masonry surrounds typically run higher—often $60,000 to $100,000+ depending on the scope.

If your property needs retaining walls, significant grading, or you’re adding a full patio and outdoor kitchen, that adds to the total. Long Island costs also factor in permit fees, which vary between Nassau and Suffolk counties, and labor rates that reflect the local market.

The best move is to get a few estimates and compare what’s actually included. Some quotes cover just the pool shell. Others include coping, decking, and all the masonry work. Make sure you’re comparing apples to apples, and ask what happens if we hit rock or groundwater during excavation—those surprises can blow up a budget fast.

Gunite is poured concrete that’s shaped on-site, so you can customize the size and shape however you want. It’s durable and handles Long Island’s freeze-thaw cycles well if it’s built right. The downside is longer install time and higher upfront cost, plus you’ll need to resurface every 10 to 15 years.

Fiberglass pools are pre-molded shells that get dropped into the excavated hole. They install faster and the surface is smooth, which means less algae buildup and lower chemical use. They typically cost 10 to 20% more upfront than basic gunite, but you save on maintenance and you never have to resurface. The tradeoff is you’re limited to existing shapes and sizes.

For Long Island specifically, both work fine if installed correctly. Gunite gives you more design flexibility. Fiberglass gives you lower long-term maintenance. It comes down to whether you want a custom shape or you’d rather minimize upkeep. Either way, the masonry surround and grading matter just as much as the pool itself.

Plan on 8 to 12 weeks from permit approval to finished pool, assuming decent weather. Permits alone can take 4 to 6 weeks depending on the town and time of year. Nassau County and Suffolk County have different processes, and some villages add their own requirements on top of county codes.

Once permits clear, excavation and shell install take a week or two. Then you’re waiting on inspections before plumbing, electrical, and decking work can proceed. Each trade has to be scheduled in sequence, and if it rains heavily or we hit unexpected groundwater, that pushes things back.

Spring is the best time to start if you want to swim by July. A lot of pool contractors get booked solid by late spring, so reaching out in winter or early spring gives you better timing. If you wait until May to start looking, you might not see a finished pool until late summer or fall.

Yes. Franklin Square is in the Town of Hempstead, Nassau County, and you’ll need a building permit before any excavation starts. The town will want to see site plans, setback measurements, and proof that the pool meets zoning requirements. You’ll also need electrical and plumbing permits for those portions of the work.

Nassau County has specific rules about how close a pool can be to property lines, and some neighborhoods have additional HOA or deed restrictions. If you’re in a flood zone, there may be extra requirements. Suffolk County has its own set of codes, and they differ from Nassau in several ways—setbacks, fencing, and drainage rules aren’t identical.

Most homeowners don’t want to deal with this themselves, and honestly, it’s easy to miss something that delays the whole project. We handle the paperwork, coordinate inspections, and make sure everything passes the first time. That’s worth paying for.

Travertine is popular because it stays cooler in direct sun and has natural slip resistance, which matters when kids are running around wet. Bluestone is another solid choice—it’s a classic Long Island look, handles freeze-thaw well, and ages nicely. Concrete pavers are the most budget-friendly and come in a lot of styles, though they can get hot in summer.

Avoid anything that’s going to crack or shift after one winter. Long Island’s freeze-thaw cycles are tough on masonry, so you want materials with low water absorption and proper installation with the right base. Limestone looks great but can be slippery when wet. Granite is durable but expensive and can get very hot.

The patio around your pool also needs to be pitched away from the house so water drains correctly. If it’s not graded right, you’ll have standing water or worse, water seeping toward your foundation. We install concrete pool surrounds in Nassau County with proper slope and use materials that are rated for outdoor use in this climate. It’s not just about looks—it’s about what’s still going to work in five years.

Yes, but it takes more work. If your yard slopes, we’ll likely need to build retaining walls to create a level area for the pool and patio. That adds cost, but it’s necessary to keep everything stable. Long Island has a lot of properties with grades, especially in Suffolk County, and if you don’t address it properly, you’ll see shifting and settling.

Drainage is the other big issue. Clay soil is common here, and it doesn’t absorb water quickly. If your yard already has standing water or runoff problems, adding a pool can make it worse unless we regrade and add proper drainage. We’ll assess that during the site visit and tell you what’s needed.

Pool retaining walls and grading aren’t just cosmetic—they protect your investment. A pool that’s built on unstable ground or in an area with poor drainage is going to have problems. Cracks, uneven settling, and water damage are all preventable if the site is prepped correctly from the start. We handle that as part of the install so you’re not dealing with issues later.
