Most people have no idea what to ask a plumber for. Start with what it is doing.
Each one is a page rather than a paragraph, because each one is a different conversation with a different worry underneath it.
Water heaters and tankless
Haskell replaces gas and electric water heaters and converts houses to tankless across Ocean County, from Waretown and Barnegat to Long Beach Island. Frank Haskell is a New Jersey master plumber, license #7471, and the business is bonded and insured.

New construction and remodels
Haskell's own Facebook page calls the business new construction and remodeling specialists, and the work runs from the rough-in on a new shore home to a gutted kitchen or bath. Frank Haskell is a New Jersey master plumber, license #7471, and the business is bonded and insured.

Winterizing shore homes
Haskell winterizes shore homes and businesses across Ocean County, from Long Beach Island to the mainland towns, so a house that sits empty does not open in the spring with a burst pipe. Frank Haskell is a New Jersey master plumber, license #7471, and the business is bonded and insured.

Not sure which of these it is? Call Frank at (732) 269-7978 and tell him what it is doing, or send the job over.
Also on the truck
These have no page of their own yet, for the honest reason that there is no photograph and no customer quote on file for them. They are still one phone call away, like everything above.
Boilers and hydronic heat
Boilers, baseboard and hydronic heat, valves, controls and thermostats, so the heat comes on when the weather turns.
Drain and sewer lines
Stoppages cleared, drain and sewer lines cleaned or replaced, and cut and cap work when a house is coming down.
Leaks and repairs
Leak detection and repair, including slab leaks, plus the fixture, faucet, toilet and pump repairs every house needs.
Gas piping
Gas lines run for fire pits, fireplaces, grills, generators and gas water heaters, inside the house or out on the deck.
Water softeners and filters
Softeners and whole-house filters that take the hard water and the chlorine taste out of what comes from the tap.
The questions that do not fit on one page.
Real questions off the forums and the state's own guidance, including the generator ones, answered without a sales pitch.
Do I need a permit to have a clogged drain cleared?
No. New Jersey's construction code counts the clearance of stoppages, and the replacement of faucets or their working parts, as ordinary plumbing maintenance, which needs no permit and no notice to the township. Re-piping, new fixtures and a new water heater are a different matter, and those go through the construction office.
The state code (PDF)Can a tankless water heater heat the house too?
It can. Haskell's own water heater page noted that a tankless unit can work as a combination hot water and boiler unit with a hydronic heating system, so one appliance covers the showers and the baseboard. Whether it suits a particular house comes down to the heating load, so call and talk it through.
Haskell's own site, archivedDoes a new gas line for a fire pit or generator need a permit?
In Waretown it does. The Township of Ocean lists the re-piping of gas lines and new gas installations among the work that needs zoning and construction permits before it starts, and other townships enforce the same state code through their own construction offices.
Township of OceanCan you find a leak under a slab?
Leak detection and repair, slab leaks included, is on the service list his own site published. A water bill that jumps, a warm spot on the floor or the sound of water with every tap closed are the usual reasons people call, and finding where it is comes before any digging.
