The plumbing under the remodel
A Hamptons renovation is a plumbing job in disguise: the kitchen moves, the bath count goes from three to six, the pool house gets a shower and a bar sink, the range goes to gas and the grill and the fire pit follow, and the 1970s copper or the 1990s polybutylene comes out. The plumber is on the job before the tile and after it, and the quote is a set of line items that the national guides price one by one.

Gas, where there is gas
Natural gas reaches some village streets and not most of the fork; the rest is propane, at $3.086 a gallon statewide in July 2026, and a propane range, grill and pool heater are the same $20-a-foot hookups from a tank instead of a meter. National Grid’s conversion pages would not render for us, so we do not say which streets are on the main; the plumber we send you to knows.
Permits and the licence
A remodel’s plumbing is permitted by the building department as part of the job: the Town of East Hampton wants two sets of quarter-inch plans, the licensed contractor’s paperwork, workers’ compensation and a survey, and its permit desk ran 16–20 weeks behind in 2026; its 13-question building FAQ says nothing specific about plumbing, and neither does the Town of Southampton’s Building & Zoning page, which lists contractor licences among what it processes. New York has no state plumbing licence; the trade is licensed county by county and town by town, and Suffolk County’s licensing page would not load for us, so we do not quote its exam or its fee. What we do is ask every plumber for the county licence and the insurance before we send you to them.
FAQ
Common questions
Do I need a permit to replace a water heater or boiler in East Hampton?
Ask the building department, because it does not say online. The Town of East Hampton’s Building Department publishes its permit requirements — two sets of quarter-inch plans, licensed-contractor documentation, notarized signatures, workers’ compensation, a survey — and a 13-question FAQ that never mentions plumbing, water heaters, boilers or gas piping; its fees rose in May 2024 and its desk ran 16–20 weeks behind in 2026. The Village of East Hampton issues in two to four weeks. The general pattern for like-for-like equipment swaps that touch no structure or service is a lighter permit, but no Town page states it, so we do not. The code applies either way: a temperature-and-pressure relief valve set no higher than 210°F and 150 psi, and an expansion tank on a closed system. The plumber we send you to files what the department asks.
How much does a plumber cost in the Hamptons?
Nobody local publishes a rate, so the honest answer is the national one plus the drive. Plumbers charge $45–200 an hour by experience — an apprentice $45–90, a journeyperson $60–110, a master $80–200, a residential average of $80 — with a service call of $100–250 that usually includes the first hour, a trip fee of $50–300 on its own, flat-rate simple calls of $100–400 and an average job of $340 ($182–500), per one national guide’s 2026 figures. After hours runs time-and-a-half to triple, or $300–400-plus flat. The three Hamptons companies we checked say call for a quote; one offers 18-month 0% financing and one ran a $0 diagnostic promotion in late summer 2026. Plumbers who work the far ends of the fork charge for the drive whether the line says so or not.

You tell us about the house once: where it is, what is wrong or what you want done, and when. We put you in touch with one licensed, insured plumber who works your town and does that kind of work, and they call you within one business day, sooner for an emergency. From there it is their quote, their schedule, their warranty. It is free for homeowners; participating plumbers pay us a referral fee for the introduction. We are not a plumbing company, and we do not sell your details; the one company we send you to is the only one that gets your number. If the job is really a septic installer’s, a well driller’s or a heating contractor’s, we say so first. We cover 9 South Fork towns and 6 kinds of plumbing work.
