A Family Plumbing Business

Two generations and counting...

Welcome to Nix Plumbing, your trusted family-owned plumbing contractor serving Pittsburgh, PA, and surrounding areas since 1983. Founded by Mark Nix, our company has proudly provided reliable, high-quality plumbing services for over 40 years. Today, under the leadership of Mark’s son, Justin Nix, we remain committed to delivering the same dedicated service and expertise that our clients have come to rely on.

As a second-generation, family-operated business, we bring a personal touch to every project—whether it’s a residential or commercial job. Our team is small, but we care deeply about the work we do and the communities we serve. From tackling new construction plumbing to the unique challenges of older buildings, Nix Plumbing specializes in a full range of essential services, including sewer line repair and replacement, gas line services, dye testing, backflow testing, and detailed camera inspections. Additionally, we offer some HVAC services.
