We get calls every week from homeowners who hired the wrong person for the job. A handyman started a kitchen remodel and walked off when he hit the plumbing. A general contractor priced a closet shelf install at $1,800. Both situations are avoidable if you know which one to call.

Here is how to think about it for projects in Hamilton, Princeton, West Windsor, Lawrenceville, and the rest of Central NJ.

The simple test: does the project pull a permit?

This single question solves 80 percent of the confusion.

If the project requires a building, electrical, or plumbing permit in your township, you need a licensed general contractor. Hamilton, Princeton, West Windsor, Lawrence Township, and every Mercer County municipality require permits for structural work, electrical changes beyond like-for-like replacement, plumbing changes, additions, and significant renovations. A handyman is not licensed to pull these permits and cannot legally do the work.

If the project is repair, replacement, or small finish work that does not require a permit, a handyman is the better fit. You will pay less per hour and they can start sooner.

What a handyman is right for in Central NJ

Real examples of what we recommend a handyman for, not a GC:

Mounting a TV or installing shelves. Replacing a faucet, garbage disposal, or showerhead with like-for-like. Patching drywall (anything under maybe a 4 ft square). Painting interior rooms. Repairing a sticking door or window. Replacing a broken outlet or switch (same location, same type). Installing a ceiling fan where wiring already exists. Touching up trim, base shoe, quarter-round. Hanging mirrors or art that needs anchors.

Typical handyman rate in Mercer County: $75 to $130 per hour, often with a minimum. Many cap out at one or two-day jobs.

What a general contractor is right for

A licensed general contractor is the right call when the project involves any of these:

Structural work. Removing walls, adding load-bearing supports, raising ceilings, cutting new openings in exterior walls. A handyman cannot legally do this and homeowner insurance won't cover the damage if something fails.

Plumbing rerouting. Moving a sink, toilet, or shower more than a foot from its current location. Adding a new bathroom. Running new supply or waste lines. Permit required, plumber must be licensed, and the GC coordinates.

Electrical beyond like-for-like. Adding circuits, upgrading the panel, running new wiring for a kitchen, hardwiring smart home devices, anything 240V. Permit required, licensed electrician must do the work.

Kitchen or bathroom renovations beyond cosmetic. If you are touching cabinets and plumbing and tile and electrical, that is four trades to coordinate. A GC sequences them so each shows up at the right phase and doesn't damage the previous trade's work.

Any addition or new construction. Foundation, framing, mechanicals, roofing, finishes. Always a GC.

Whole-home renovations. Even if individual pieces could be done by single trades, the coordination cost of doing it yourself across plumbing, electrical, HVAC, drywall, flooring, painting, and inspections wipes out any savings.

NJ licensing rules that matter

New Jersey requires anyone doing home improvement work over $500 to be registered as a Home Improvement Contractor with the NJ Division of Consumer Affairs. A registered HIC has a 13HC number. You can verify any contractor at the NJ Division of Consumer Affairs website.

Beyond HIC registration, specific trades require their own licenses. Electricians must be NJ-licensed. Plumbers must be NJ-licensed. HVAC contractors must be NJ-licensed. A handyman doing electrical work without a license is illegal and uninsurable.

MHG Contracting carries an active NJ Home Improvement Contractor registration, $1,000,000 general liability insurance, and workers comp for all employees. Any contractor you consider should produce these documents on the first visit. If they hesitate, that is your answer.

Where the cost math actually breaks for homeowners

The mistake we see most often: hiring a handyman for a project that should have a GC, then paying twice when it goes wrong.

Example from last year. A Hamilton homeowner hired a handyman to "just install a new vanity and toilet" in a powder room. The handyman cut the existing waste pipe wrong, didn't vent the new sink properly, and finished the tile before the floor was leveled. We were called in to redo it. The original quote was $2,800. The actual final cost to make it right was $9,400, including demolition of the new but bad work. If they had called a GC first, the whole project would have been $5,500 to $7,000 done right.

The other direction is rarer but happens. A GC will sometimes quote a $400 handyman task at $1,500 because the GC's overhead, insurance, and crew costs aren't structured for small jobs. If the project is a single afternoon of work with no permits, get a handyman or call us and we will refer you to one we trust.

The four-question pre-call test

Before you decide who to call, run your project through these:

1. Does it require a permit in your township? If yes, GC.

2. Does it involve more than one trade (plumbing, electrical, framing, finish)? If yes, GC.

3. Will the work take more than two full days? If yes, probably GC.

4. Does the project's "if it fails" risk include water damage, fire, or structural failure? If yes, GC, every time.

If you answered no to all four, you probably want a handyman.

Why family-owned matters more than franchise

This is the question every Hamilton, Princeton, and West Windsor homeowner asks once they have decided on a GC. Family-owned local contractors live in the towns they build in. The owner is on the job site. The crew is consistent across projects. If something goes wrong two years later, the same person who signed the contract picks up the phone.

Franchise GCs have salespeople, project managers, and revolving-door crews. The person who quoted your job is not the person doing the work. There is no continuity, and the warranty is only as good as the franchise location's tenure.

For most kitchens, bathrooms, basements, additions, and renovations in Central NJ, family-owned beats franchise on quality, communication, and accountability. The franchise advantage is national marketing, which doesn't help you when the floor is uneven.
