What drives the cost of fire sprinkler installation in ST Clair

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

Before you hire in ST Clair

Lead-safe work rules apply to most homes

The typical home in ST Clair was built around 1959. 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

51% 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 ST Clair building department before work starts.
