John Heyrich Inc.

John Heyrich Inc. has served Montclair, New Jersey, and surrounding communities for decades as a family operated plumbing contractor. The company holds a valid master plumber license in New Jersey and maintains an active rating of 4.1 stars across 43 customer reviews. Operating from their Montclair base, the team provides residential plumbing services to homeowners in Montclair, Verona, and Glen Ridge, handling everything from routine repairs to complex boiler and radi ator diagnostics. The business is reachable by phone at (973) 744-0454.

Without a published website, John Heyrich Inc. relies on word of mouth and repeat customers rather than digital marketing. The company does not appear to specialize in high efficiency heat pumps or indoor air quality systems; their documented work focuses on traditional plumbing repairs, boiler service, radiator troubleshooting, toilet repair, and drain clearing. Service descriptions align with what reviewers describe: diagnostic work on heating systems and general fixture repairs. No manufacturer certifications, rebate programs, or unusual guarantees are mentioned in available materials.

Customer feedback highlights two technicians by name: Andy and Ramon, whom reviewer Peter Boyle specifically praised as "technically strong and nice at the same time." Their work included addressing a boiler issue, a faulty radiator, and two toilets in a single visit. However, negative reviews raise concerns: reviewer Matthew Frankel described an incident where owner John Heyrich canceled an appointment after a misunderstanding over a 7 AM phone call, and reviewer Kiara Lo reported condescending behavior during a billing dispute and a drain-clearing job that required a second visit. These contrasting accounts suggest service quality may depend on which technician arrives and how issues are communicated.
