Heidler

What Heidler does

Heidler, Inc. is a family-owned and operated plumbing and heating contractor headquartered at 208 Taylor Avenue, Annapolis, Maryland, founded in 1947 and continuously operated by the same family for nearly 80 years. The company provides full-service residential and light commercial plumbing, heating, sewer, drain cleaning, water treatment, and bathroom/kitchen remodeling services across 13+ communities in Anne Arundel County, with 24/7 emergency dispatch and a stated 60-90 minute response time. Its portfolio is delivered as in-person skilled trade services using standard plumbing tools and equipment (hydrojetting, video camera inspection, leak detection), with no proprietary software platform, app, or API; the company also maintains brand-level service partnerships for heating and gas fireplace products and a financing relationship with GoodLeap.

The business generates revenue primarily through transactional service work billed on flat-rate, upfront pricing, supplemented by a recurring Plumbing Preventive Maintenance Agreement (PMA) subscription ($89.95 new member, $79.95 renewal). Distribution is direct-to-consumer via a 24/7 phone line (410-268-7191), online scheduling, and local SEO across community-specific service-area pages; marketing relies on Google and Facebook reviews (988+ five-star reviews), an active blog, coupons, and a newsletter. The customer base is dominated by individual residential homeowners, with a secondary commercial segment driven largely by backflow testing and certification requirements.

Operating scope is a single Maryland jurisdiction, with no subsidiaries, no parent company, no outside equity, and headcount reported at 1-10 employees. The company holds Master Plumber & Gas Fitter licensure at the state, county, and city levels, and displays memberships in PHCC, HPBA, ABC, and Quality Service Contractors, alongside EPA Lead-Safe certification. Strategic activity is limited to community-by-community service-area expansion, multi-brand heating partnerships, and the PMA and financing additions; no funding, M&A, leadership changes, or technology platform development is evidenced.

Direct peers

• Len The Plumber: Mid-Atlantic residential plumbing, heating, and drain cleaning company headquartered in Maryland. Operates a very similar direct-to-consumer service model (24/7 emergency, flat-rate pricing, licensed technicians) in overlapping Anne Arundel and greater Baltimore-Washington geographies, making it Heidler's closest direct competitor.
• CroppMetcalfe: Mid-Atlantic home services company offering plumbing, HVAC, electrical, and indoor air quality services across the DC/Maryland/Virginia region. Directly comparable to Heidler in the residential plumbing and heating space with similar flat-rate pricing and emergency service positioning.

Broad incumbents

• Mr. Rooter Plumbing: National residential and commercial plumbing franchise with broad service coverage. Operates as a scaled brand and marketing platform in the same residential plumbing category, but does not specialize in the Annapolis local market the way Heidler does.
• Roto-Rooter: Largest U.S. plumbing and drain cleaning services company, operating nationally with a strong brand and 24/7 emergency positioning. Heavily overlaps with Heidler's drain cleaning, sewer, and emergency plumbing services but at national scale rather than local specialization.
• Benjamin Franklin Plumbing: National residential plumbing franchise known for on-time guarantees and licensed technician service. Competes in the same residential plumbing and water-heater installation category as Heidler, with broader geographic reach via franchising.

Regional players

• Michael & Son Services: Mid-Atlantic home services provider (plumbing, electrical, HVAC) headquartered in Virginia. Operates a similar direct-to-consumer residential service model in the broader DC-Baltimore region, comparable to Heidler in service mix and customer type though with a different immediate service territory.
• Wedge Plumbing: Maryland-based residential plumbing contractor serving the Baltimore-Washington corridor. Direct overlap with Heidler in residential plumbing, water heater, sewer, and drain cleaning services, though it operates across a wider regional footprint than Heidler's Anne Arundel focus.
• Catons Plumbing: Maryland-based residential and commercial plumbing company serving the Baltimore metro area. Comparable to Heidler in service categories (plumbing, drain cleaning, water heaters) and customer base, with overlapping but not identical service geography.

Others

• HomeServe USA: Home repair and maintenance membership/warranty provider that partners with local contractors (including plumbers) to serve residential customers. Comparable to Heidler's PMA membership concept and similar customer demographic, but operates as an enabling/warranty layer rather than a direct service provider.
• ServiceMaster Restore: National residential restoration and cleaning services franchise. Related to Heidler through the home services ecosystem and overlap on water-damage-related plumbing work, but operates in a different primary service category (restoration vs. plumbing installation/repair).
