Welch Brothers Co Inc

Welch Brothers Co. Inc. Plumbing and Heating has anchored itself in Lowell, MA, since 1904, making it one of the oldest continuously operating contractors in the Merrimack Valley. MA License #12870, a 4.4-star average across 14 reviews, and round-the-clock availability on every day of the week distinguish this shop from newer arrivals. The company serves both residential and commercial customers across Lowell and Chelmsford, handling everything from a leaking faucet to full boiler replacements. Licensed and insured work covers plumbing, heating, remodeling, water heaters, steam systems, and fuel-conversion projects.

What separates Welch Brothers from the field is its dual expertise in plumbing and heating combined under one roof, with capabilities that include high-efficiency boiler installations, tankless water heater retrofits, and natural-gas conversions. The company accepts Visa, Mastercard, and Discover, and its website promotes available rebates on qualifying equipment upgrades. A full bathroom or kitchen remodeling offering gives residential customers a single contractor for both plumbing rough-in and finish work, rather than coordinating separate trades.

Reviewers repeatedly highlight the willingness of Welch Brothers technicians to go beyond a standard service call. K M describes calling after a basement flood from a broken boiler pressure tank, leaving a message late at night and receiving a callback from Derek who walked her through shutting off the water supply remotely before sending a crew first thing the next morning. Another reviewer, BC 09, credits the owner with personally driving a service truck on a Saturday when all technicians were committed, diagnosing a failed boiler indirect tank and improvising a temporary fix until a part sourced from distributors as far as the West Coast could be delivered by Monday evening.
