Gallagher's Plumbing & Heating
Company Overview
Our journey began in 1986 when Gallagher's Plumbing and Heating Inc. was launched in Ironia, Randolph Township. At Gallagher's Plumbing & Heating, we see ourselves as a respected, family-owned business. Our commitment is to treat both our clients and staff with the honesty and respect we wish to receive.
Initially, Dave Sr. and his brother-in-law Jim handled fieldwork, with Diana overseeing office operations. They specialized in both new heating systems and replacements, in addition to plumbing for new homes and remodels. During the prosperous mid-80s, we grew swiftly, focusing more on plumbing for new builds. We installed plumbing for builders like Toll Brothers, Kaplan, K. Hovnanian, Beazer Homes, and Ryan Homes, along with various custom builders. As a result of our rapid growth, we relocated from our home-based business to the Hackettstown area in 1988. From our early days to now, we have focused on satisfying homeowners and contractors with top-quality work at fair prices.
We attribute our success to our skilled and friendly staff, both in the field and in the office. Every project we undertake, big or small, is handled with care and professionalism, all while maintaining competitive pricing.

Recommended Customer Reviews
Hired Gallagher to swap out an old oil boiler for new natural gas boiler and hot water heater, i couldn't be happier with the job. super clean plumbing and the nicest people to work with. I highly recommend them.
Gabrielle W.Came on time. wore masks in my home. Never took them off even when they were working alone! Did an awesome job! Very reasonably priced. Changed and installed traps in 3 sinks in less than 1 hour and then they were out the door. I was amazed, I thought they would be here all morning. Efficient, respectful, and prompt. Would definitely use again (and again and again).
Nancy P.We have used Gallagher's over the years. They have always offered prompt and reliable service. Their pricing has always been upfront and clear. Today I called with an issue and they could not help me because they were booked. Most companies would have just stopped at that point. The people at Gallagher's went above and beyond what they needed to do by helping us find another company that could come out and look at the issue. They truly care about their customers and I would highly recommend them. 512 warren Hackettstown.
Michaelanne S.These people are awesome! My furnace went out on a Sunday, they were able to squeeze me in on Monday and fixed my problem quickly and efficiently. The Service was excellent - and YES they DO really take their shoes off LOL :). I think I found my new heating, cooling and plumbing service :) Thanks Gallagher's!!
Sue M.We recently moved into the neighborhood and wanted a pot filler installed. We called Gallagher's Plumbing and they were on-time, knowledgeable, and respectful of our new home. I would not hesitate to recommend them, they stand behind their work, and are extremely trustworthy.
