How much does a plumber cost in Troy, MI?

What are the most common plumbing problems in Troy homes?
▾
Most common plumbing issues in Troy: (1) Hard water scale — Troy receives Oakland County water with 12–18 GPG hardness. This shortens water heater lifespan to 7–10 years and causes mineral buildup in appliances. (2) Copper pinhole corrosion — homes built in the 1960s–1980s with original copper supply lines develop pitting corrosion from decades of hard water exposure. (3) Sump pump failure — Troy's clay-influenced soil and spring snowmelt create basement water infiltration risk. (4) Aging PVC drain joint failures in homes from the 1970s–1980s. (5) Water softener maintenance — Troy homeowners frequently have water softeners that require annual service.
Does Troy have hard water?
▾
Yes. Troy receives water from the Great Lakes Water Authority (GLWA) through the Oakland County system. Hardness averages 12–18 grains per gallon — classified as hard to very hard. Hard water shortens water heater lifespan (to 7–10 years instead of 12+), creates mineral scale inside pipes and appliances, and causes limescale on fixtures. Most Troy plumbers install and service whole-home water softeners and can advise on the right grain capacity for your household size.
Do Troy homes have galvanized pipes?
▾
Most Troy homes do not have galvanized supply pipes. Troy developed primarily in the 1960s through the 1990s — after copper supply had replaced galvanized in new construction. Homes built before 1965 in Troy's older established neighborhoods may have some galvanized sections, but this is far less common than in Warren, Sterling Heights, or Detroit. The primary supply pipe concern in Troy is copper pinhole corrosion from hard water — different problem, different solution (PEX repiping or spot repair rather than full galvanized replacement).
Are Troy plumbers licensed through Michigan?
▾
Yes. All Michigan plumbing contractors must hold a state license through LARA. Verify any Troy plumber's license at michigan.gov/lara. Troy Building Department requires permits for water heater replacement, any new plumbing installation, and sewer lateral work. Troy inspectors are thorough — ensure your plumber pulls the permit and schedules the inspection.
Does Troy require a permit for plumbing work?
▾
Yes. Troy City Building Department requires permits for water heater replacement, any new plumbing rough-in, sewer lateral repair or replacement, and any work that modifies the home's plumbing system. Your licensed plumber should pull the permit. Troy's inspection process is consistent — plan for a 1–3 day permit turnaround and a post-completion inspection before walls are closed on any rough-in work.
