Before you hire

New York does not license this trade statewide, so there is no state licence to look up; some cities and towns set their own rules.
Get two or three written estimates for anything beyond a small repair, and compare what each includes.
Ask for a certificate of insurance. Any New York business with employees must carry workers' compensation, and general liability protects you if something goes wrong on your property.
Ask whether the job needs a building permit and who pulls it; your town or city building office can confirm.
Keep payments tied to progress rather than paying most of the price up front.

Common questions

How do I keep pipes from freezing?

Keep the heat on, even when you are away; let faucets on outside walls drip on the coldest nights; open cabinet doors under sinks on outside walls; and shut off and drain outdoor spigots before winter.

What should I do if a pipe bursts?

Shut off the main water valve right away, then call a plumber. Find your main shut-off before winter so you are not looking for it in an emergency.

Do plumbers need a state licence in New York?

No. New York has no statewide plumbing licence; some cities and towns license plumbers locally, so check with your city or town building office.
