Mortensen Custom Plumbing

Mortensen Custom Plumbing is a full-service residential plumbing provider rooted in Flagstaff, AZ. The company operates under the leadership of owner Marty Mortensen, who began working with tools and plumbing designs in a family business. After pursuing a Biology degree at Northern Arizona University, chance and personal inclinations steered him away from a medical career. In 2003, Marty earned his Plumbing Contractors License and launched his own business in Flagstaff, driven by a love for the community and a genuine knack for problem-solving.

A believer in transparency, Mortensen Custom Plumbing emphasizes upfront pricing, ensuring clients receive a firm cost estimate before any work begins—no surprise bills or unplanned expenses. The company also prides itself on unmatched quality, focusing on precise diagnoses, clear explanations, proactive prevention strategies, and safeguarding homes for the long term. To support client confidence, they provide written warranties, making it easy to seek follow-up help when needed.

Their service offerings are extensive, covering everything from whisper-quiet garbage disposals; trench-less (“No-Dig”) sewer replacements; water treatment and filtration systems; tankless water heating installations; to residential baseboard and radiant heating, septic repairs, flood-safety enhancements, maintenance services, and more.

Client feedback underscores exceptional reliability and professionalism. One longtime customer praised Marty for arriving punctually, providing clear repair or replacement options, maintaining wallet-friendly pricing, delivering meticulous cleanup, and exemplifying kindness and transparency—qualities that earned ongoing trust and referrals.

Serving Flagstaff neighborhoods primarily in zip codes 86001, 86004, and 86005, Mortensen Custom Plumbing blends deep local roots, skilled craftsmanship, and customer-focused practices to deliver dependable home plumbing solutions
