The arithmetic is appealing and it's real: a general contractor's overhead and profit sits on top of every subcontractor invoice on your job. Hire those subcontractors yourself and that layer comes off.
What doesn't come off is the work the markup was paying for. Someone still has to write the scope, vet the trades, sequence them, catch the conflicts, manage inspections, and be there when the tile setter arrives to find the plumber hasn't finished. If that someone is you, the savings are real. If that someone is nobody, the savings evaporate in delays and rework.
This is an honest inventory of what the job involves in Suffolk County, so you can decide whether you want it.
1. Licensing — verify it, don't assume it
Suffolk County requires home improvement contractors to hold a county license. The definition is broad: repair, remodeling, alteration, modernization, home elevation, carpentry, fencing, driveways, and painting of residential structures all fall under it. Nassau County licenses separately, which matters if you're hiring someone who works across the county line.
A license number on an invoice is not verification. Confirm it with the county's consumer affairs office directly. This is a five-minute call that occasionally saves an entire project, because in New York a contractor who performs licensed work without a license faces real obstacles enforcing payment — which sounds like it favors you until you consider that you've now got an unfinished job and a dispute instead of a bathroom.
2. Insurance — certificates from the agent, not the contractor
Two coverages matter, and they cover different things:
- General liability — damage the contractor causes to your property or someone else's. If a plumber's torch starts a fire, this is the policy that responds.
- Workers' compensation — injuries to their workers. This is the one that reaches back to you. An uninsured worker injured at your house can become your homeowner's policy's problem, and your policy may not want it.
Request certificates sent directly from each trade's insurance agent, verify the dates are current, and ask to be named as a certificate holder so you're notified if a policy lapses mid-job. When a GC runs the project, they carry this burden and verify their subs. When you contract directly, it's yours.
Before you hire anyone directly, ask your homeowner's insurer how acting as your own general contractor affects your coverage. Policies differ, and it's a question much better answered in advance than during a claim.
3. Contracts — with each trade, meeting state requirements
You'll have one contract per trade instead of one for the job. Each one needs to be a real home improvement contract under New York law: written and signed, identifying the contractor and license number, including the required notices about mechanic's liens and how deposits are handled, and giving you the right to cancel until midnight of the third business day after signing.
Payments have to bear a reasonable relationship to work actually completed. This is your main protection, and it's worth being firm about: money tied to milestones, not to the calendar and not to the trade's cash flow.
One thing a direct-hire homeowner should understand plainly: mechanic's lien rights belong to anyone who supplies labor or materials to your property. If you pay a contractor who doesn't pay their supplier, the supplier can still come after the house. Lien waivers collected with each payment are how that gets prevented, and it's a step that people running their own job routinely skip.
4. Sequencing — the part that's harder than it looks
Trades have to happen in order, and the order has dependencies that aren't obvious until you've been through it. A simplified bathroom:
- Demolition
- Framing changes
- Plumbing rough-in and electrical rough-in — which have to coordinate with each other
- Rough inspection, which has to pass before anything gets covered
- Insulation, then drywall and finishing
- Tile — which needs the substrate right, and holds up everything behind it
- Plumbing and electrical trim
- Final inspection
- Punch list
Every one of those is a separate business with its own calendar. Miss a window and you're not delayed a day; you're delayed until that trade's next opening, which on a busy Long Island summer can be two or three weeks. Multiply by six trades and you understand how a ten-week project becomes five months.
The other sequencing cost is conflict. When the electrician and the plumber both want the same bay, somebody decides. With a GC, that's their call and their problem. Contracting directly, that call is yours — usually by phone, usually immediately, usually with both trades waiting.
5. Permits and inspections
Permits are pulled through your town's building department — Islip, Brookhaven, Smithtown, Huntington and the rest each run their own, with their own forms, fees and turnaround. Inspections have to be scheduled at specific points, and work covered before a required inspection can have to be opened back up.
Individual trades typically pull their own permits for electrical and plumbing. The overall building permit is often the homeowner's to pull on a direct-hire job — and it's worth knowing that pulling the permit yourself can shift responsibility for code compliance onto you rather than a contractor.
Unpermitted work has a long tail. It surfaces at resale, during an appraisal, or when an insurance claim gets examined, and by then correcting it costs several times what the permit would have.
6. Your actual time
The part nobody quantifies. On an active renovation, expect daily contact with someone, multiple site visits per week, and decisions that can't wait until evening. Trades work during business hours. If your job requires you to be reachable at 7:15 on a Tuesday morning to decide where a vent goes, and you're in a meeting, the vent goes where the installer thinks it should.
So when does direct hiring make sense?
It works well when: the project is one or two trades; you have construction experience or a lot of flexible time; the work isn't structural; and you can handle the back-and-forth calmly.
It goes badly when: six trades have to interlock; the house is old and full of unknowns; there's structural or engineered work; you're living in the house during the work; or you're managing it around a full-time job.
There's a third arrangement most homeowners don't know exists. You contract the trades directly and keep the markup off your job, but a consultant writes the scope, runs the bidding, builds the sequence and handles oversight — paid a flat fee for the management rather than a percentage of everything installed.
That's what Sub Pro LLC does. Whether it's worth it depends on your project and how much of the list above you actually want.
