Found my outdoor cleanout that was covered up for years and no other company could find! … They use drop cloths and clean up when they are done.

Leaking pipe right now?

Shut off the water first if you can reach the valve safely, then call us, day or night.

908-873-6686

Outside regular hours and on holidays, emergency service requires a $250 upfront emergency fee. When paid, the standard $49 service fee is waived. During regular hours there is no emergency fee. Additional repairs are quoted before work begins. We respond immediately upon contact; dispatch and arrival depend on availability and location.

Do this now

  1. Shut the main valve. Usually where the water line enters, near the meter.
  2. Stay clear of electricity. Don't enter standing water or touch electrical controls near the leak.
  3. Open a low faucet to drain the pipes and take pressure off the leak.

Water Heater Replacement: common questions

When should I replace my water heater?

When the tank itself is leaking, because a tank can't be patched. Replacement also makes sense when a heater more than about 10 years old keeps breaking down, since another repair rarely pays off.

How long does a water heater last?

A standard tank water heater usually lasts about 8 to 12 years. Hard water shortens that because minerals settle as sediment at the bottom of the tank.

How much does water heater replacement cost?

It depends on the type, the size, how hard it is to reach and whether the venting or gas lines need to change, so we price each job after we assess it. The service call is $49, waived if you go ahead with the work. Written upfront flat-rate pricing options. You choose.

Do you install tankless water heaters?

No. We don't install or replace tankless water heaters. We do diagnostics, repairs and maintenance on them.

Do I need a permit to replace a water heater in NJ?

Often yes, and a gas water heater may need a fuel gas permit too, but requirements depend on the scope of the job. Your local enforcing agency has the final word.
