Metcalf Plumbing Service, LLC: Catonsville, MD's Trusted Plumber

Last updated August 03, 2026

Metcalf Plumbing Service, LLC has built a steady reputation as one of Catonsville, Maryland's go-to residential and commercial plumbing contractors. Operating out of 10 Winters Ln B, the company serves homeowners and businesses throughout Baltimore County and Howard County, handling everything from routine repairs to full system inspections. With a 4.9-star rating drawn from 770 reviews, the numbers reflect what customers in the region have come to expect: straightforward pricing, licensed technicians, and work that holds up.

What separates Metcalf from many plumbing outfits in the area is a structural choice that's easy to overlook: the company does not pay its technicians on commission. That single policy shapes every service call. Technicians have no financial incentive to upsell parts you don't need or rush through an inspection to move on to the next job. Instead, the company leads with honest, upfront costs and a thorough look at your plumbing system before recommending next steps. For homeowners who have been burned by surprise invoices before, that approach carries real weight.

Owner and CEO Leslie Metcalf runs the business with a family-oriented philosophy that shows up in how the company engages with the Catonsville community, not just in how it handles service calls. From licensing compliance to community outreach, Metcalf Plumbing keeps its footprint local and its standards consistent.

History and Founding of Metcalf Plumbing Service in Catonsville

Metcalf Plumbing Service was founded by Leslie Metcalf, who holds the title of Owner, CEO, and Master Plumber, as well as a Gas Fitter designation. The company is rooted in Catonsville and has grown by focusing on the Baltimore County and Howard County markets rather than spreading thin across the broader metro region. That geographic focus has allowed the team to build genuine familiarity with the housing stock and infrastructure common to communities like Catonsville and Ellicott City, where older homes often come with plumbing quirks that require experienced hands.

The company describes itself plainly: small, but thinking big. That self-assessment captures the approach well. Metcalf Plumbing doesn't chase volume for its own sake. The emphasis has always been on doing the job right, leaving the customer informed, and earning the next call through quality rather than marketing pressure.

Metcalf Plumbing Services and Specialties

Metcalf Plumbing handles a wide range of residential and commercial plumbing work across Catonsville and the surrounding counties. The company serves both homeowners dealing with day-to-day repairs and commercial clients managing more complex systems.

• Kitchen and bathroom plumbing repairs and installations
• Water heater inspection, replacement, and installation
• Toilet repairs and valve replacements
• Pipe installation and replacement
• Full plumbing system inspections with documented findings
• Gas fitting services
• Commercial plumbing for businesses in Baltimore County and Howard County

Water heater work deserves particular mention because Metcalf has turned it into a community education effort, not just a service line. The company runs an Oldest Water Heater Contest, inviting homeowners across Baltimore County and Howard County to submit their aging units for consideration. The contest is designed to get people thinking about an appliance most households ignore until it fails, often at the worst possible moment. By framing the issue as a friendly competition, Metcalf creates a low-pressure way to start a conversation about home safety and energy efficiency.

On every service call, the company's technicians follow a process that goes beyond the immediate repair. They inspect the surrounding system, flag potential issues, and explain their findings to the homeowner before any additional work is proposed. That inspection-first model means customers leave with a clearer picture of where their plumbing stands, whether or not they choose to act on every recommendation that day.

Team and Leadership at Metcalf Plumbing

Leslie Metcalf leads the company as Owner, CEO, Master Plumber, and Gas Fitter. The Master Plumber and Gas Fitter credentials are earned designations that carry specific licensing requirements under Maryland state law, and Metcalf Plumbing maintains full licensure and insurance coverage that meets the state's minimums for Master Plumbers. That compliance isn't a formality; it's a baseline that protects customers on every job.

Among the technicians on the team, Mike has earned consistent recognition from customers for the way he handles service calls. A journeyman plumber, Mike brings a teaching approach to his work that customers notice. During a recent kitchen sink installation, he took the time to walk a homeowner through the process of replacing a running toilet valve, turning a routine visit into a practical lesson. That kind of interaction reflects the broader culture at Metcalf: the goal isn't just to fix the problem and leave, but to leave the customer better informed than they were before.

In the Press

Metcalf Plumbing Service has received local news coverage for its community initiatives, with particular attention paid to the Oldest Water Heater Contest. The contest has drawn coverage as an example of a locally owned business using a creative, community-focused format to address a genuine public safety issue. Aging water heaters are a leading source of home water damage and energy waste, and Metcalf's approach of turning awareness into a neighborhood event has resonated with local media covering Baltimore County and Howard County communities.

The press attention reflects something real about how the company operates: Metcalf Plumbing treats community engagement as part of the business, not an afterthought. The contest isn't a one-time promotion; it's a recurring program that brings the company back into the conversation with homeowners who might not have thought about their water heater since the last time someone mentioned it.

What Customers Say About Metcalf Plumbing

With 770 reviews and a 4.9-star rating, Metcalf Plumbing's customer feedback points consistently toward two themes: the quality of the technical work and the way technicians treat the people they're working for. Customers frequently mention feeling respected and informed rather than rushed or upsold.

Linda Delp's experience captures the teaching dimension of Metcalf's service well:

Mike came out again to install some pipes for a kitchen sink... he taught me how to replace a valve on a toilet that was constantly running. He is extremely knowledgeable, patient and generous.

- Linda Delp

That kind of feedback, where a customer walks away having learned something, isn't accidental. It reflects a company culture that values the customer's understanding of their own home, not just the completion of a work order. Bette McKown put her experience more succinctly:

I will definitely use Metcalf for my plumbing needs. Top notch!

- Bette McKown

And repeat business is a pattern that surfaces across the review base. One customer summed it up simply:

Metcalf is always my first call for plumbing work!

That kind of loyalty, expressed plainly without prompting, is the clearest signal that the company's approach to pricing transparency and quality workmanship is landing with the people it's meant to serve.

Location and Community: Catonsville, MD

Metcalf Plumbing Service operates from 10 Winters Ln B, Catonsville, MD 21228, a location that puts the company squarely within the communities it serves most. Catonsville sits along the western edge of Baltimore County, and its mix of older single-family homes and newer developments creates steady demand for plumbing services that range from legacy pipe repairs to modern fixture installations. The company's service area extends into Howard County as well, covering Ellicott City and surrounding neighborhoods where similar housing patterns apply.

The Oldest Water Heater Contest is the clearest example of how Metcalf engages with the Catonsville area beyond individual service calls. By inviting homeowners from across Baltimore County and Howard County to participate, the company creates a recurring touchpoint with the community that isn't tied to a sales pitch. The goal is awareness, and the format makes it approachable.

For homeowners thinking about the broader financial picture, Catonsville's real estate market has seen home values appreciate at roughly 6.8% annually in recent years, with projections settling closer to 3.9% going forward. In that context, maintaining a home's plumbing system isn't just a comfort issue; it's a factor in protecting the asset. A failing water heater or an undetected pipe problem can erode property value quickly, which makes the kind of proactive inspection work Metcalf offers a practical investment alongside any renovation or upkeep budget.
