What drives the cost of fire sprinkler installation in Dearborn

  • Building size, height and occupancy hazard

  • Water supply strength and whether a fire pump is needed
  • New underground service or tap into an existing line

Before you hire in Dearborn

Lead-safe work rules apply to most homes

The typical home in Dearborn was built around 1952. Painting, window, siding and remodeling work that disturbs paint in homes built before 1978 must follow the EPA lead-safe (RRP) rule. Ask any contractor for their RRP certification before work starts.

Older plumbing and sewer lines

71% of homes here were built before 1960, when cast iron drains, clay sewer laterals and galvanized supply pipe were standard. A sewer camera inspection before buying or remodeling is cheap insurance.

Permits: check with the Dearborn building department before work starts.
