Water Heaters in Sagaponack, NY

A tank if the budget and the basement are ordinary: $800–2,500 installed for 40–50 gallons, labor $150–450 for a swap, 6–15 years of life by one guide and 8–12 by another. A tankless if the house fills up on Fridays and empties on Mondays: $2,638 average installed ($1,404–3,901), labor $600–1,900 because the venting and gas change, about 20 years of life, and no tank to fail in an empty house. A heat-pump water heater if the basement is big and warm: $1,200–3,500 installed and PSEG Long Island rebates up to $1,200 on an ENERGY STAR model in 2026, the only water-heater rebate left after the federal credit ended in 2025. On a propane or oil house, which is most of the fork, the fuel at the street decides more than the brochure does.

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.

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.
