What drives the cost of subfloor repair in Port Huron

  • Joist or framing repairs found once opened
  • Flooring removal and replacement over the repair
  • Toilet, tub or appliance removal and reset

  • The age of the home: the typical Port Huron home was built around 1955, so older materials, lead-safe rules and hidden damage can add time

Before you hire in Port Huron

Lead-safe work rules apply to most homes

The typical home in Port Huron was built around 1955. 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

59% 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 Port Huron building department before work starts.
