About 35% of Belmar's 1.61 square miles is water. The Atlantic lies to the east and the Shark River runs along the northern edge. Close to that much water, the calls follow a pattern: basements that take water, sump pumps working harder than their owners realize, and slow leaks nobody sees in a house used only in summer.
This page works outward from the water. We start at the river and the marina, move through the blocks behind the boardwalk, and finish with the borough's permit rules. We dispatch from Neptune, and everything here applies to ZIPs 07719 and 07715.
Along the Shark River: wet basements and sump pumps
Belmar sits on the south bank of the Shark River, and homes near the river or the municipal marina sit close to a lot of water. Basements near water can take in groundwater as well as runoff, so ask which one is yours.
A sump pump answers that problem, but only if it is sized for the inflow, the check valve is installed correctly and the discharge line goes somewhere legal. Ask the borough about discharge rules before you route anything. A battery backup matters because storms often take power with them.
Check your flood zone before you build or renovate
Belmar offers a "What's my Flood Zone?" lookup on its website. Use it before you plan a basement project, since the zone may affect what work is allowed and what insurance requires. The plumbing side of a project follows from that answer.
The blocks behind the boardwalk: slow leaks in summer houses
With 29.5% of housing units vacant in 2020, many Belmar houses sit closed for months. A pinhole in a supply line can run for weeks before anyone sees it. The signs are a musty smell, a swollen baseboard or a water bill that looks wrong for an empty house.
Belmar's Water/Sewer Department reads meters and bills quarterly, so a leak can run through an entire billing cycle. Close every tap and check the meter dial. If it moves, leak detection with a pipe microphone or thermal camera finds the pipe before anyone opens a wall.
Waterfront problems and what to do about them
Match the symptom to the likely cause, then call us for the confirmation.
| Symptom | Likely cause | What we check |
|---|---|---|
| Damp basement after rain | Groundwater or surface runoff | Sump pump, floor drains, downspouts. |
| Water bill higher than usual | Hidden supply leak | Meter test, pipe microphone. |
| Pump runs constantly | Failed check valve or high inflow | Float, valve, discharge line. |
| Musty smell, no visible water | Slow leak or dry trap | Moisture meter, trap seals. |
| Basement puddle in a storm | Power failure and pump off | Battery backup, outlet circuit. |
Belmar's permit and inspection rules, in one place
The Belmar Construction Department says unpermitted work can be fined from $500 to $2,000. That is a strong reason to ask before replacing a water heater or adding a fixture. Plumbing, mechanical and fire inspections are held Wednesday through Saturday, 6 to 8 a.m., and the department runs a permit and inspection portal online.
That early window means you need to plan access. Someone must be home at 6 a.m. If you are an out-of-town owner, arrange a key holder. We can explain what the job requires, and your plumbing installation quote will say how inspection fits.
Marina, boardwalk and seasonal businesses
Seasonal operators face their own calls.
Opening-week checks
Run every fixture and drain before the first customer to catch dry traps and failed fittings.
Water heater sizing
A kitchen that serves a summer crowd needs recovery capacity, not just tank size.
Closing for winter
Drain lines and shut off the water at the main so an empty building does not freeze up.
Landlord and tenant lines
Settle in writing who owns each drain and heater before the season, not during a backup.
Before we arrive: a Belmar home with water where it should not be
Waterfront basements can fill quickly, so first steps matter.
Shut off the water
Close the main valve where the line enters the house. If the leak stops, it came from the supply side.
Avoid wet electrical areas
Stay out of basements with water near outlets, a panel or a sump pump cord. Never touch a panel while standing in water.
Clear the area
Lift stored items off the floor and leave a path to the sump, water heater and main.
Call the 24/7 line
Call (732) 466-1098. Give us your ZIP, whether the pump is running, and whether power is on.
Which ZIP is which, and where else we work
Most Belmar addresses use 07719. Some use 07715, a code unique to Belmar. We cover both with the same dispatch.
Belmar also borders Avon-by-the-Sea, Neptune Township, Wall Township, Lake Como and Spring Lake. For neighboring towns, see our help in Bradley Beach or Neptune City. The service area page has the full list.
What this page leaves out
Seawalls, bulkheads and foundation work are not plumbing. Neither is flood cleanup or mold removal. We will tell you where our work ends.

The Belmar Construction Department fines unpermitted work from $500 to $2,000, so ask them what your job needs. Their inspections run Wednesday through Saturday, 6 to 8 a.m.
Often it is the right start, with a battery backup. If water enters through walls or cracks, other trades may be involved. We will say what falls outside plumbing.
A hidden leak is the usual reason. Close every tap, check the meter dial, and call us if it moves. Ask the Water/Sewer Department how your meter is read.
Your lease decides. Many owners ask a manager to authorize repairs. Photograph the damage and send written notice.
