Who Performs Foundation Inspections?
Foundation Repair Contractors
Many foundation repair companies offer free or low-cost assessments as part of their sales process. These inspections can be thorough and are performed by experienced field personnel who have seen thousands of foundation conditions.
Advantage: Often free or $50-$150. Experienced, practical assessment. Limitation: Inspector works for a company that sells repairs. Recommendations may not be fully objective.
Cost: $0-$250 (often refunded if you hire them for the repair)
Independent Home Inspectors
A home inspector who includes foundation assessment in their general home inspection provides a broader view but typically does not have the specialized depth of a foundation contractor or structural engineer.
Best for: Buyers in the process of purchasing a home who want a general assessment alongside the full home inspection.
Cost: $400-$600 (for full home inspection including foundation assessment)
Licensed Structural Engineers
A licensed PE (Professional Engineer) with structural expertise provides the most authoritative assessment of foundation condition. Their report is defensible, suitable for permit applications, insurance claims, and real estate disclosures.
Advantage: Independent, licensed, most credible. Can specify repair method precisely. Limitation: More expensive; may not include repair recommendations (only assessment).
Cost: $400-$1,000 for residential; $800-$3,000 for commercial.
What to Expect in a Foundation Inspection
Exterior Assessment
- Visual inspection of foundation walls, perimeter, and adjacent grade
- Assessment of drainage patterns (does water flow away from the foundation?)
- Observation of any visible cracks in the foundation, brick veneer, or stucco
Interior Assessment
- Inspection of drywall, door frames, window frames for cracking and misalignment
- Floor level measurement - a laser level or manometer maps differential elevation across the home
- Inspection of basement or crawlspace structure and conditions
Documentation
A written report should include:
- Observations and photographs
- Measured floor level data
- Assessment of severity and likely cause
- Recommendations (repair urgency, suggested method, or recommendation for further investigation)
What a Foundation Inspection Won’t Tell You
A visual inspection has limits:
- It doesn’t show what’s beneath the slab
- It can’t definitively identify the root cause without soil testing or subsurface investigation
- It doesn’t tell you what the soil conditions are at depth
- It can’t detect closed voids or pre-collapse sinkholes (GPR scanning required for that)
For complex cases - unusual cracking patterns, suspected sinkhole activity, or pre-purchase on an older structure - additional investigation (soil boring, GPR) may be recommended after the initial inspection.
Is the Inspection Worth the Cost?
Yes, almost universally. A $400 inspection that identifies a $12,000 repair before you purchase a home could be worth tens of thousands of dollars. An inspection that tells you your foundation is fine (and explains what you’re seeing is normal shrinkage cracking) is worth $400 for the peace of mind.
For any property where you’re seeing symptoms - uneven floors, sticking doors, visible cracks - an inspection cost is trivial relative to the decision you’re about to make.
