Lead Service Line Replacement in Montclair, NJ

Updated August 30, 2026 • Montclair NJ Guide

If your Montclair home was built before the 1950s, the pipe carrying water from the street into your house has a real chance of being lead, galvanized steel, or lead-lined brass. New Jersey law requires every water system in the state to find and replace those lines by 2031, and the Montclair Water Bureau has already inventoried the township and is rolling out a no-cost replacement program in 2026. Here’s what that actually means for your address, how to check your line today, and what your options are if you don’t want to wait for the town’s schedule to reach your block.

Why This Is a Bigger Deal in Montclair Than in Newer Towns

Lead service lines are almost entirely a pre-1950s problem — lead pipe fell out of common use well before it was formally banned, and towns built up mostly after that point simply don’t have many of them. Montclair isn’t one of those towns. Large sections of the township, particularly the older neighborhoods closer to downtown and along the historic streetcar-era blocks, were built out well before that cutoff. That’s the same housing stock that shows up in our older-home maintenance guide and our lead paint testing guide — old paint and old pipes tend to show up on the same properties, for the same reason.

The 2031 Law, in Plain Terms

In 2021, Governor Murphy signed New Jersey’s Lead Service Line Replacement Law. It requires every community water system in the state to do three things: identify the material of every service line in its territory (including the homeowner-owned portion, not just the utility’s side), notify customers whose line is lead, galvanized, or unknown, and replace all of them by 2031 — at a minimum pace of 10% of the known total each year, with a possible five-year extension available under specific circumstances.

That law applies to the Montclair Water Bureau the same way it applies to New Jersey American Water, Newark, or any other system in the state. What's genuinely useful for Montclair residents is that the township isn't waiting until 2030 to get moving — the inventory work is done, and a formal replacement program is already scheduled to launch in 2026.

What Montclair's 2026 Program Covers

The Water Bureau has compiled a townwide inventory covering lead, galvanized, brass, copper, and unknown-material service lines, submitted that data to the NJDEP, and made it available through the township. Based on the township's own public statements, the program launching in 2026 is described as a no-cost replacement — meaning the town is covering the private, house-side portion of the line in addition to its own infrastructure, not just the section it already owned under the street.

That's worth underlining because it isn't universal. Some New Jersey systems have historically replaced only the utility-owned portion up to the curb stop and left the homeowner-side section — and its cost — to the resident. If Montclair's no-cost framing holds as the program rolls out, it removes what is usually the single biggest financial objection homeowners have to getting this done.

Galvanized and brass lines are included alongside lead for a specific reason: galvanized pipe has an internal surface that can trap and later release lead particles even if the pipe itself isn't lead, and older brass fittings and pipe can contain enough lead content to matter. If your line was flagged as galvanized rather than lead, don't assume that puts you outside the program.

How to Check Your Address

If You Don't Want to Wait

Nothing stops you from hiring a licensed plumber or water line contractor to replace a confirmed lead or galvanized service line privately, ahead of the town's schedule. The obvious trade-off is that doing it yourself means paying for it yourself — a full replacement from the curb stop to the house typically runs $2,500–$8,000+ depending on length, depth, and whether the crew can trench an open lawn or has to work under a driveway or established landscaping. Our water main repair & replacement cost guide breaks down that pricing in more detail, including trenchless options for homes where digging up hardscaping isn't practical.

Selling a home before the town gets to your address is one of the more common reasons people choose to pay for it privately rather than wait — a confirmed lead line is the kind of thing that comes up in a home inspection and can complicate or slow a closing. If you're preparing an older home for sale, our guide to selling an older Montclair home and pre-sale checklist cover how this fits alongside the other older-home items buyers ask about.

What to Do While You Wait

A confirmed or suspected lead line doesn't mean you need to stop drinking your tap water, but a few precautions are reasonable until it's replaced. Run the tap for 30–60 seconds after it's sat unused for several hours — overnight, or after a workday — before using it for drinking or cooking, since water that's been sitting in the pipe picks up more lead than water that's actively flowing. A pitcher or faucet filter certified to NSF/ANSI Standard 53 for lead removal is a low-cost way to add a margin of safety in the meantime, and it's worth checking your own filter's certification specifically rather than assuming any water filter handles lead — many are only rated for chlorine taste and odor.

If your home is also on the older side of Montclair's hard-water spectrum, this is a reasonable moment to look at whole-house filtration rather than a single faucet unit — our water softener and filtration cost guide covers what a whole-house system runs and how it differs from a point-of-use filter.
