Foundation Inspection Before Closing: What Buyers Should Look For | KAR Concrete

Learn the critical elements of foundation inspection before closing a property deal, with insights from KAR Concrete's 49 years of experience.

Why Most Foundation Inspections Miss The Mark

Most contractors in Ventura County are getting this wrong. They overlook the soil conditions that can drastically impact a foundation's integrity. For example, the expansive clay soils in areas like Oxnard and Ventura can cause significant foundation movement. A comprehensive inspection should assess soil conditions alongside visible structural elements to catch issues early.

The Spec Nobody Reads

Let's talk about building specifications. Too many times, we've stepped onto a job site only to find that crucial parts of the spec sheet, particularly regarding rebar placement and concrete mixing ratios, are ignored. According to ACI 318-19 Chapter 18, the correct PSI for residential foundations is typically 3,000 to 4,000 PSI, yet we've seen under-strength mixes lead to cracks and failures.

What Good Looks Like

A quality foundation inspection is thorough, detail-oriented, and backed by technical experience. Good inspections involve soil testing, visual inspections for cracks or water damage, and verification of compliance with relevant building codes. Properly placed #4 rebar and high-quality concrete mixes are telltale signs of a foundation built to last.

The Cost of Poor Inspection

Failing to conduct a proper foundation inspection can cost homeowners tens of thousands in repairs later. From moisture issues in Simi Valley to seismic cracks in Malibu, we've seen repair costs range from $5,000 to upwards of $50,000, depending on the extent of the damage.

Foundation Bids: Why They're Often Wrong

Foundation bids lacking specificity are an issue. We've seen bids that don't account for necessary components like proper drainage systems or fail to mention the quality of materials. A precise bid should detail each component's dimensions, material quality, and comply with CBC and IBC standards.
