Mountain High Plumbing Inc

Mountain High Plumbing Inc has served Flagstaff and surrounding northern Arizona communities since establishing their licensed operation under ROC 153084/172028. The company maintains a 4.1-star rating across 98 customer reviews and provides round-the-clock emergency availability every day of the week. Their service footprint spans six cities including Flagstaff, Sedona, Williams, Winslow, Page, and Cottonwood, delivering both residential plumbing solutions and commercial installations to homeowners and businesses throughout the region.

What distinguishes Mountain High Plumbing from competitors is their specialized expertise with Navien tankless water heater systems, a premium brand that requires factory-certified installation knowledge. Multiple reviewers specifically mention the team's willingness to go beyond the immediate repair, with technician Kleimer noted for identifying hazardous DIY plumbing work near a water main and spending additional time replacing sharkbite fittings with permanent copper connections. The company also handles new construction plumbing design and installation, water filtration system setup, and comprehensive drain cleaning services across their service territory.

Customer stories from reviews reveal the human side of their service. Technician Dave and partner Cheyenne completed a full kitchen sink replumbing with garbage disposal installation in a single day, earning high praise for efficiency. Another reviewer, a mobile notary business owner, described how Kleimer repaired a failed water pump faster than expected while improving water pressure. The company has also been credited for their transparent pricing and honest diagnostic communication, with technician Aliesha noting that customers feel empowered to make informed decisions about repairs rather than simply accepting expensive recommendations.
