Gunite Pool Installation in Old Westbury, NY: Design, Cost & What to Expect

Why Old Westbury Homeowners Choose Gunite

Old Westbury sits at the heart of Nassau County's Gold Coast, a stretch of North Shore communities defined by estate-scale properties, historic horse farms, and a tradition of understated luxury. The neighborhood's median home value exceeds $2 million, and the lots — typically running from one to five acres — provide the space to build pools that match the scale of the house and grounds.

Gunite is the only pool construction method that makes sense at this scale. Unlike fiberglass shells, which come in fixed shapes and sizes, gunite pools are built on-site from a steel-reinforced concrete shell. That means unlimited customization: freeform shapes that follow the natural contours of the property, vanishing edges that frame a view, integrated spas and water features, tanning ledges, grottos, and any other element the design calls for.

The durability argument is equally compelling. A properly built gunite pool in Old Westbury will last 50 years or more with routine maintenance. The concrete shell handles Long Island's freeze-thaw cycles without cracking, and the plaster or pebble finish can be resurfaced every 15–20 years to restore the pool to like-new condition. For homeowners who are building for the long term — and in Old Westbury, most are — gunite is the clear choice.

Gunite Pool Design Options for Old Westbury Properties

The design possibilities with gunite are essentially unlimited, but most Old Westbury projects fall into a few broad categories based on the property's character and the homeowner's vision:

Gunite Pool Cost in Old Westbury, NY

Pool costs in Old Westbury are higher than Long Island averages for several reasons: larger lot sizes mean more complex excavation and grading, the permitting process in Nassau County is thorough, and homeowners in this market expect premium finishes and features. Here's a realistic breakdown:

These ranges reflect the full installed cost — excavation, shell, plumbing, electrical, equipment, coping, decking, and finish. They do not include landscaping, fencing, or pool house construction, which are typically scoped and priced separately.

The single biggest variable in pool cost is site conditions. Old Westbury's soil is generally favorable — well-drained sandy loam over most of the area — but properties with significant grade changes, large trees near the pool location, or underground utilities can add meaningfully to excavation costs. A site visit before any estimate is non-negotiable.

The Gunite Pool Construction Process

Understanding the construction sequence helps set realistic expectations for timeline and what you'll see on your property at each stage. A typical gunite pool installation in Old Westbury takes 10–16 weeks from permit approval to first swim, depending on weather, material lead times, and project complexity.

Permitting a Pool in Old Westbury (Town of North Hempstead)

Old Westbury falls within the Town of North Hempstead, which has its own building department and permit requirements separate from Nassau County. Pool installations require a building permit, and projects that include retaining walls, drainage structures, or significant grading may require additional approvals.

The North Hempstead permit process is thorough. You'll need engineered drawings, a site plan showing the pool location relative to property lines and structures, and documentation of the pool's structural design. The review process typically takes 6–10 weeks, though complex projects or those requiring variance applications can take longer.

Old Westbury also has specific setback requirements — the pool must be a minimum distance from property lines, the house, and any easements. These setbacks affect where on the property a pool can be located and are a critical part of the early design process. We review setback requirements before finalizing any design.

We handle the entire permitting process as part of our service. You won't need to navigate the building department yourself — we prepare the application, submit the drawings, respond to any comments from the reviewer, and schedule all required inspections.

Pool Features Popular in Old Westbury

Old Westbury homeowners tend to invest in features that elevate the pool from a backyard amenity to a resort-quality experience. The most requested upgrades we see on Old Westbury projects:

Choosing a Pool Contractor in Old Westbury

The pool contractor you choose will have more impact on the outcome of your project than any other single decision. In a market like Old Westbury — where projects are large, expectations are high, and the properties are irreplaceable — this decision deserves careful thought.

The most important thing to verify is whether the contractor is licensed and insured in New York State. Pool installation requires a Home Improvement Contractor license from Nassau County, and the contractor must carry general liability and workers' compensation insurance. Ask for certificates of insurance before signing anything.

Beyond licensing, look for a contractor with a demonstrated portfolio of work in Nassau County's Gold Coast communities. The permitting process, soil conditions, and design expectations in Old Westbury, Brookville, Muttontown, and Sands Point are different from those in other parts of Long Island. A contractor who works regularly in these communities will navigate the process more smoothly and produce results that fit the neighborhood's character.

Ask to see completed projects — not just renderings or photos from the manufacturer's catalog. Visit a finished pool if the contractor can arrange it. Talk to previous clients. A contractor who is proud of their work will welcome this scrutiny; one who deflects or makes excuses is a red flag.

Finally, be cautious of unusually low bids. Pool installation in Old Westbury has real costs — materials, labor, equipment, permitting — and a bid that is significantly below the others is almost always cutting corners somewhere. The question is where: cheaper materials, unlicensed subcontractors, inadequate steel reinforcement, or a shell that won't pass inspection. The cost to fix a poorly built pool is far greater than the savings on the original bid.

Pool Landscaping in Old Westbury

A gunite pool on an Old Westbury estate is rarely a standalone project. The pool is the centerpiece, but the landscape design that surrounds it determines whether the finished result looks like a resort or a construction site. The two need to be designed together.

Privacy screening is almost always a priority. Old Westbury lots are large, but neighbors exist, and most homeowners want to enjoy their pool without feeling observed. Arborvitae, Leyland cypress, and American holly are the most common screening choices — fast-growing, dense, and evergreen. For a more refined look, boxwood hedges, hornbeam, or beech hedges provide a formal structure that complements the architecture of most Old Westbury homes.

Poolside planting requires careful species selection. Plants near a pool are exposed to chlorine splash, reflected heat from the patio, and the foot traffic of wet swimmers. Ornamental grasses, lavender, rosemary, and low-growing junipers handle these conditions well. Avoid plants that drop significant leaf or flower debris into the pool — this creates maintenance headaches and can clog pool equipment.

Landscape lighting tied to the pool's automation system creates a unified nighttime experience. Uplighting on specimen trees, path lighting along the patio perimeter, and underwater LED lighting in the pool all work together to make the outdoor space as usable after dark as it is during the day.
