Price

What drives the cost of foundation underpinning in Algonac

  • Method: concrete underpinning, push piers or helical piers
  • Number of locations and depth to stable soil
  • Interior or exterior access and working room
  • Soil testing or engineering required
  • Whether the house is lifted back toward level
  • Restoration of concrete, landscaping or finishes
  • The age of the home: the typical Algonac home was built around 1967, so older materials, lead-safe rules and hidden damage can add time

Before you hire in Algonac

Lead-safe work rules apply to most homes

The typical home in Algonac was built around 1967. 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

40% 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 Algonac building department before work starts.
