On the bench

Aqua Serenity Pools

On the bench

Levco Pool & Spa, Inc.

Hillsborough, Somerset (adjacent) County

Strongest verified credential in the set — BBB accredited since 1991 with an A+ grade and 40 years in business — but it's a Somerset County HQ, not in-county, so confirm they still actively cover your specific Hunterdon town before committing. Credential verified against the state registry, date shown.

Why trust this page

We pull credentials from the official registries ourselves and print the date next to every status — pool construction, installation, and renovation in NJ requires an active Home Improvement Contractor (HIC) registration from the NJ Division of Consumer Affairs (license format 13VHxxxxxxxx). Verify at the NJ License Verification system: https://newjersey.mylicense.com/verification/Search.aspx — search by business name or license number. Pool electrical work additionally requires a licensed electrical contractor (NJ Board of Examiners of Electrical Contractors); plumbing connections require a licensed master plumber. Routine pool cleaning/maintenance with no construction component is not separately licensed in NJ.. Picks are editorial judgment on the checkable record: years in the trade, complaint patterns, review consistency, real presence in the county. No company paid to be listed, none can pay to become a pick, and when a pick has a weak spot we print it. Here are the full rules.

Every pool company we checked

The category has real local depth: five of the eight vetted providers are headquartered inside Hunterdon County (Glen Gardner, Clinton Township, Lebanon Township x2, and Ringoes x2), which is unusual for a specialty trade in a county this size. Two more (Levco, Carlton) are Somerset County neighbors with genuine, long-standing service reach into Hunterdon towns. Watch for the lead-gen pattern here: several companies based well outside the county (Custom Pool Pros in Freehold/Monmouth, D. Panetta Contracting in Randolph/Morris, Patrick T. Sharkey in Morristown, Poseidon's Custom Pools in Toms River) run large batches of templated, town-specific SEO landing pages claiming Hunterdon coverage — "Delaware Hunterdon County NJ," "Union Hunterdon County NJ," etc. — despite having no physical presence anywhere near the county. Those were excluded from the table.

Registry status comes straight from the state's verification system on the date shown, and you can rerun any number there yourself in about two minutes. Review scores are what the named platforms report and we have not audited them. BBB grades as of July 2026. "Based in" is the registered address city, which sometimes differs from where a company says it operates. An active registration is the floor, not an endorsement; the picks we would actually call are above.

What it costs

NJ inground pool installs typically run $65,000-$120,000+, varying by material: vinyl liner ~$28,000, fiberglass $46,000-$87,000, concrete/gunite $70,000+ (source: Angi/HomeGuide 2026 cost data, corroborated by NJ-specific installer cost pages). Treat as a planning range — get itemized quotes, since Hunterdon's rural lot conditions (excavation access, well/septic setbacks) commonly push jobs toward the higher end.

Before you hire

Confirm the HIC registration is current, not just listed — status can lapse between renewal cycles, and one of the companies here had conflicting active/inactive signals across two data sources on the same day. Check it yourself at the state lookup, not just on a company's website badge.
Get the excavation and permit plan in writing before signing. Pool installs in Hunterdon's rural townships routinely trigger septic/well setback reviews, steep-slope or floodplain checks, and township geotechnical sign-off — a contractor who can't walk you through your specific township's process is a warning sign, not a formality to skip.
Separate the installer from the electrician and plumber. Pool bonding/wiring needs a licensed electrical contractor and fill/drain lines need a licensed plumber — an HIC registration alone doesn't cover either. Ask who's doing that work and ask for their license numbers too.
Ask for a written maintenance/warranty handoff plan before the pool is finished, not after. A recurring complaint pattern across review sites in this category is good construction work paired with poor post-install communication — get service-call response time and warranty terms in the contract, not a verbal promise.
For service-only companies (openings, closings, weekly maintenance, repairs), note that routine pool cleaning/maintenance itself is not a licensed trade in NJ — only construction/installation/renovation work over $500 requires HIC registration. Don't expect a license number from a pure maintenance outfit and don't treat the absence of one as a red flag by itself.

Questions neighbors actually ask

Do pool installers in Hunterdon County need a license?

Yes, for construction work. Any company installing, renovating, or repairing a pool on your property for $500 or more must hold an active New Jersey Home Improvement Contractor (HIC) registration through the state's Division of Consumer Affairs — the same registration that covers decks, patios, and additions. Plain pool cleaning and maintenance (no construction) isn't separately licensed in NJ.

How much does it cost to install an inground pool in New Jersey?

Most NJ homeowners pay $65,000 to $120,000+ for an inground pool, with the material driving the swing: vinyl liner pools run around $28,000, fiberglass averages $46,000-$87,000 depending on size, and concrete/gunite typically starts above $70,000 and can climb past $200,000 with custom features. Site conditions (excavation difficulty, permits, well/septic clearances common in Hunterdon's rural townships) push costs toward the higher end. (Source: Angi/HomeGuide 2026 national data and NJ-specific pricing pages — treat as a planning range, not a quote.)

How do I check if a pool contractor's license is actually active?

Use the state's own lookup, not a review site's badge — go to the NJ Division of Consumer Affairs license verification system and search by the company's HIC number (format 13VHxxxxxxxx) or name. In this vetting pass, one company's license status showed as inactive on one aggregator and active on another checked the same week — aggregators can lag or misread the state feed, so verify directly before signing anything.
