About M.J.L. Plumbing & Well Pump Services
M.J.L. Plumbing & Well Pump Services operates as a plumber in Hummelstown, Pennsylvania, earning a 5.0-star rating across 35 verified customer reviews. The business maintains round-the-clock availability throughout the week, with reduced hours on Sunday from 8 a.m. to 4 p.m., serving residential clients throughout Hummelstown and the surrounding Dauphin County communities. Reviewers consistently describe the principal technician as prompt, personable, and professional, noting his ability to schedule same-day appointments and complete repairs efficiently.
Customer reviews repeatedly highlight three distinguishing qualities: transparent upfront pricing with options presented before work begins, expertise in well pump systems that many area contractors lack, and honest assessments that sometimes recommend DIY fixes over paid repairs. Multiple reviewers describe receiving callbacks suggesting self-service solutions despite the potential loss of revenue, a practice several customers cited as evidence of genuine integrity. The business also offers comprehensive plumbing diagnostics, addressing issues ranging from frozen pipe emergencies to new construction installations.
