What it costs, what moves the price, and what boiler replacement in Roxbury actually involves.
$11,600 to $17,150
The middle half of the 124 boiler replacements we completed across the company, as of October 2026. A quarter came in under $11,600 and a quarter ran above $17,150.
That is our own job history, not a national average and not a teaser price. We price the same way in every town we cover, so this is the range to plan around in Roxbury Township, NJ. It excludes sales tax. We publish it because you cannot plan around "call for pricing," and because a number we have to stand behind keeps us honest. Your quote is fixed before any work starts, and what moves it is covered below.
Roxbury is the one North Jersey town where the gas main really does arrive, and that changes this job more than most people expect. The sections below cover what the work involves, what sets your price, and the local conditions we plan around here specifically. The range above comes from our own completed jobs rather than a national estimate, and we price the same way in every town we cover.
Roxbury is the North Jersey town where the gas main genuinely reaches. New Jersey Natural Gas told the Board of Public Utilities in 2019 that it served 5,462 residential customers in the township, against roughly 8,600 homes, and our own records agree from the other direction: natural gas leads oil here by about three to two. That makes Roxbury the mirror image of its neighbours, where Hopatcong runs more than six to one the other way. It also means this is where live oil-to-gas conversions actually come up, and replacement is the moment to decide rather than pay for the same labour twice.
Close to three jobs in ten here mention a boiler, baseboard, radiator or steam. That is the heaviest hydronic concentration we work in anywhere in New Jersey. The township also splits in two: along the Route 10 corridor in Succasunna, Ledgewood and Kenvil gas leads oil by nearly two to one, while at Landing and Bertrand Island on Lake Hopatcong the two run close to even, which is the signature of seasonal cottages converted to year-round use one addition at a time. Tankless is rare across the whole township, which matters more here than it would elsewhere: with this much baseboard, a boiler replacement forces a hot water decision, and that is the moment to price every option rather than repeat what is already in the basement.
If your radiators hiss and have a vent on the side, you are on steam. Steam boilers are sized to the connected radiation - the actual square footage of all your radiators - not to a heat loss calculation. Get that wrong in either direction and the system either never satisfies or short-cycles and hammers. It is the one place in heating where the old method is still the right method.
Hot water systems are sized to heat loss like anything else, and there the old nameplate is usually far too big.
The boiler is a box. The piping around it is the system. On steam, the header has to be piped the way the manufacturer draws it or the boiler carries water over into the mains and you get wet steam, banging and early failure. On hot water, primary-secondary piping and correctly sized circulators are what let a condensing boiler actually condense instead of running hot and returning hot, which throws away the efficiency you paid for.
This is the hardest part of a quote to compare, because it is invisible once the jacket is on. When one number comes in far below the others, this is usually what is missing.
If the old boiler also made your domestic hot water through a tankless coil, replacing it forces a decision. An indirect tank gives excellent recovery and efficiency but needs floor space. A combi makes heat and hot water in one wall-hung box, which suits tight mechanical rooms but limits simultaneous demand. A standalone water heater keeps the two independent, so a boiler fault does not also mean cold showers. The difference between them is thousands of dollars, and a quote that does not address it is not finished.
This part of Sussex and Morris County is served by New Jersey Natural Gas and JCP&L. Both run programmes worth checking before you buy: NJNG SaveGreen rebates and financing, JCP&L financing through NEIF, and the broader zero percent utility financing guide. The federal 25C credit expired at the end of 2025; we cover what that changed in this article.
One to two days, longer on a large multi-zone system. We drain down, remove the old boiler, set the new one, build the near-boiler piping to the manufacturer drawing, run venting and condensate, wire the controls, then refill, purge and balance each zone. We commission with a combustion analyser and leave you the readings and the permit close-out.
When you invite us into your home, we take that responsibility seriously. Every project - big or small, is handled with care, respect, and craftsmanship you can feel. Our Lifetime Workmanship Guarantee means every job is done right — or we make it right, fast.
Every technician undergoes rigorous training and continuous skill upgrades.
