When you buy a home in CT or NY, the standard home inspection includes a foundation walk-through. The findings often drive negotiations at closing or follow-up specialty inspections. A typical foundation report uses language that sounds alarming whether the issue is cosmetic or structural. Here's how to read it.
Standard sections you'll see
Most foundation reports include:
- **Visual condition** — overall assessment of what the inspector saw
- **Cracks** — locations, sizes (often by feeler-gauge measurement), patterns
- **Moisture** — staining, efflorescence, active seepage, ambient humidity
- **Bowing or deflection** — measured against a plumb reference
- **Floor flatness** — slope readings if uneven
- **Drainage** — exterior conditions, downspout discharges, grading
- **Recommendations** — usually one of: monitor, further evaluation, repair
How to translate the language
- **"Settlement cracks"** — almost always vertical, usually historical, often stable. Cosmetic to medium-severity
- **"Hairline cracks"** — generic term, see our crack widths guide for what actually matters
- **"Efflorescence noted"** — water has moved through the wall at some point. Inspector saying moisture is reaching the interior
- **"Lateral deflection observed"** — the wall is bowing. This is structural, get it inspected by a foundation specialist
- **"Recommend further evaluation by a qualified specialist"** — inspector found something they don't want to call but think a professional should look at. Almost always worth doing
- **"Active leak" / "Active moisture"** — water is currently entering. Different from historical staining
What deserves immediate action
- 1Any horizontal crack, regardless of width
- 2Any bowing or deflection over 1 inch
- 3Active water entry through cracks or the slab
- 4Stair-step cracks in block walls
- 5Any crack actively growing month to month
What's worth monitoring but not urgent
- Stable vertical cracks under 1/8 inch
- Hairline cracks at typical concrete-shrinkage locations (corners, around windows)
- Old efflorescence with no current water entry
- Minor floor cracks that are tight and not transmitting water
What's a red flag in the report itself
If the report has any of these features, get a specialist's second opinion before signing or budgeting:
- Generic language without specific measurements ("some cracking observed")
- No photographs of identified issues
- Recommendations that pivot to selling a service (some inspectors are also installers, conflict of interest)
- Categorical statements like "foundation is sound" or "all cracks are cosmetic" without supporting evidence
When to get a specialist's read
A general home inspector is a generalist. They're trained to identify foundation issues, not always to diagnose the cause or scope a repair. Anytime the report uses language like "recommend further evaluation," or finds anything in the immediate-action category above, a foundation specialist's free inspection is the next step. We typically respond within 48 hours and the inspection itself is free, regardless of whether you book the work.
