Don’t Get Scammed: The Ultimate Foundation Inspection Checklist

Resources and Tools

Inspection

A solid foundation inspection is more than a quick crawl, vague measurements, and a salesperson’s pitch. If you’re investing thousands—sometimes tens of thousands—into stabilizing, waterproofing, or repairing your home’s foundation, you deserve a thorough, data-driven inspection backed by qualified professionals. Here’s exactly what a real foundation inspection should include, step by step.

1. Pre-Inspection Preparation

✅ Credentials Check

  • Licensed Structural Engineer: At a minimum, an engineer with a P.E. license or a certified foundation specialist supervised by one.
  • Contractor License & Insurance: Confirm the company’s state contractor license and general liability insurance.
  • Third-Party Verification: Look for BBB accreditation or Angi/HomeAdvisor reviews.

✅ Document Review

  • Historical Reports: Gather any past foundation or structural inspections, including level surveys, repair bids, and warranty paperwork.
  • Home History: Note previous water events, landscaping changes, or interior renovations that might affect your foundation.

2. On-Site Walk-Through

✅ Visual Exterior Assessment

  • Perimeter Grading & Drainage: Inspect soil slope away from the house, gutter downspouts, and signs of pooling water near footings.
  • Foundation Walls & Cracks: Look for vertical, horizontal, or stair-step cracks. Note location, length, and width.
  • Masonry & Mortar Condition: Check brick or block stability, efflorescence (white salt deposits), and bowing.

✅ Visual Interior Assessment

  • Floor Levels: Walk the entire main floor, noting areas of bounce, slapping, or slope—especially at transitions (e.g., doorways, thresholds).
  • Wall & Ceiling Cracks: Inspect around windows, corners, and load-bearing walls for new or expanding cracks.
  • Doors & Windows: Note sticking or gaps that may indicate shifting.

3. Precision Measurements

✅ Digital Level Survey

  • ZipLevel / Bosch Digital Level: Take systematic readings at predetermined grid points (corners, mid-spans, center of rooms).
  • Benchmarking: Set a stable reference point (benchmark) and record all measurements relative to it.
  • Repeatability: Take each reading at least twice; average results to minimize error.

✅ Moisture & Soil Testing

  • Moisture Meter Scan: Use a pin or pinless meter on interior slabs and exterior footings to detect elevated moisture levels (>12–14%).
  • Soil Probe / Core Samples: (When applicable) A geotechnical engineer may perform test borings to assess soil bearing capacity and moisture content.

✅ Thermal Imaging (Optional)

  • Thermal Camera Scan: Reveal hidden water intrusion, insulation voids, or voids under slabs that could affect stability.

4. Structural & Load Analysis

✅ Pier & Beam Inspection

  • Beam Condition: Examine interior support beams for rust, rot, or improper welding.
  • Pier Footings: For pier-and-beam homes, check accessible pier footings for signs of shifting or soil washout.

✅ Load Path Evaluation

  • Load-Bearing Walls & Columns: Identify main structural supports and ensure any recommended repair plan ties into these correctly.
  • Span & Over-Span Concerns: Verify that proposed solutions respect the concrete’s low flexural capacity (piers should not “over-span”).

5. Engineering Report

A professional engineer’s report should include:

  • Scope of Work: Detailed description of recommended repairs, including pier locations, types (push, helical, micropile), and structural supports.
  • Stamped Drawings: Site plans with pier placement schematics, cross-sections, and any required structural details (e.g., steel size, weld types).
  • Calculation Summary: Load calculations, soil bearing pressures, factor-of-safety, and design life assumptions.
  • Permit-Ready Documentation: All items needed for local building permits and inspections.

6. Clear, Tiered Recommendations

A quality inspection report offers multiple plan options, each justified with data:

  1. Minimum Viable Plan: Address only the most severe areas (e.g., readings < –0.75″ or visible structural cracks).
  2. Moderate Plan: Extend support to zones with moderate movement (–0.50″ to –0.75″).
  3. Conservative Plan: Full perimeter stabilization, including areas with slight movement (–0.25″ to –0.50″) for maximum protection.

Each tier should include cost estimates, pros/cons, and phased scheduling options.

7. Transparent Pricing & Warranty

  • Line-Item Breakdown: Labor, materials, permits, engineering fees—all spelled out clearly.
  • No Hidden Fees: Avoid vague “system fees” or “miscellaneous charges.”
  • Warranty Details:
    • What is covered (e.g., pier performance, waterproofing).
    • For how long (lifetime vs. limited term).
    • Transferability to future owners.
    • Exclusions (e.g., undocumented moisture sources).

8. Q&A & Final Review

Before you sign:

  • Ask for References: Speak with recent customers who have done similar work.
  • Site Walk-Through: Request a final meeting to discuss the plan with the engineer or senior project manager.
  • Confirm Scheduling & Logistics: Excavation timing, access points, protection of landscaping/finishes, dust control.

🔑 Key Takeaways

  1. Real Expertise Over Sales Pitches: Verify credentials, demand an engineering review, and insist on data.
  2. Data-Driven Decisions: Use levels, moisture meters, and soil tests to guide your repair scope.
  3. Tiered, Transparent Plans: Choose the phase that matches your home’s actual condition and budget.
  4. Own the Process: Don’t let anyone rush you. The proper inspection is thorough and technical, and it is done before you ever sign a contract.

A foundation is literally what holds up your home—your family’s shelter, memories, and investment. A proper inspection should treat it with the respect and rigor it deserves. Stay smart, stay skeptical, and let the data, not drama, guide your next foundation project.
