Frequently Asked Questions

How much does a foundation inspection cost in New York?

A basic foundation inspection typically costs $350 to $600. A licensed structural engineer's formal report typically costs $600 to $1,200. Engineering reports are required by most lenders when significant foundation issues are found.

What are common foundation problems in New York homes?

Common issues include wet or leaky basements (common due to high groundwater table and clay soils), horizontal and stair-step cracks in block or brick foundations, bowing basement walls, settling and sinking in newer construction on fill soils, and deteriorated mortar in older stone foundations. Coastal and low-lying areas face additional hydrostatic pressure issues.

When should I get a foundation inspection in New York?

Get a foundation inspection if you notice cracks wider than 1/4 inch, doors and windows that stick, uneven floors, water seeping into the basement, or white mineral deposits (efflorescence) on basement walls. A foundation inspection is especially important for homes built before 1970, many of which have older block or stone foundations.

Do I need a structural engineer for a foundation inspection in New York?

A qualified home inspector can identify visible foundation issues, but a licensed Professional Engineer (PE) is recommended for a formal structural assessment. Lenders typically require a PE report when significant cracks or settlement are found. Engineers can also design repair solutions and provide cost estimates for local soil and construction conditions.
