6 Things Your Home Inspector May Have Missed That Could Cost You Thousands

You paid $400 for the inspection. You got a 40-page report. You assumed the house was thoroughly evaluated. But home inspections have limitations that most buyers don’t discover until the first repair bill arrives — and by then, the inspector’s liability is capped at the cost of the inspection.

A home inspection is a visual, non-invasive examination. Inspectors are not required to move furniture, open walls, dig into the ground, or test every system at full capacity. Here’s what that means for what they may have missed.

They don’t test for mold — and they’re not required to. A home inspector can note visible signs of moisture — water stains, discoloration, musty odors — but standard inspections do not include mold testing. If there’s mold behind a wall, under carpet, or in ductwork, the inspector won’t find it because they can’t see it. A separate mold inspection with air sampling costs $300 to $600 and is the only way to identify hidden mold before you own the problem.

The sewer line wasn’t scoped. A standard home inspection doesn’t include a sewer scope — a camera inspection of the underground drainage pipe connecting the house to the municipal sewer. Tree roots, clay pipe deterioration, bellied sections, and cracks in the lateral line can cost $5,000 to $25,000 to repair. A sewer scope costs $150 to $300 and reveals problems invisible from inside the house.

The roof inspection was done from the ground. Many inspectors evaluate roofs visually from the ground or from a ladder at the eave line. They can identify missing shingles, damaged flashing, and obvious sagging. But they may not walk the roof, and they typically cannot assess the condition of sheathing, underlayment, or fastening patterns without removing materials. A roof that looks acceptable from the ground may have failing underlayment that guarantees a leak within two years.

Cosmetic renovations may be hiding defects. A freshly painted wall covers cracks. New flooring covers subfloor damage. A renovated bathroom hides plumbing shortcuts. Inspectors evaluate what they can see — and a seller who knows their home has problems can legally make those problems invisible with $500 in paint and flooring. If the house was recently “refreshed” with cosmetic updates before listing, ask the inspector to pay extra attention to what’s behind the fresh surfaces.

Electrical panels were evaluated — but not all the wiring. The inspector opens the electrical panel and evaluates the visible breakers, wiring connections, and grounding. They do not trace every wire through the walls. Aluminum wiring, knob-and-tube wiring, and improperly spliced connections behind finished walls are all fire hazards that a visual panel inspection can miss. If the house was built before 1975 or has had significant DIY electrical work, a licensed electrician’s evaluation is worth the additional $200 to $400.

Their liability is limited to the cost of the inspection. Most home inspection contracts include a liability limitation clause that caps the inspector’s financial responsibility at the fee paid — typically $300 to $500. If the inspector missed a $15,000 foundation problem or a $25,000 sewer line failure, your maximum recovery through the inspection contract is $400. The inspection is a risk-reduction tool, not a guarantee. Understanding its limitations — and supplementing with specialized inspections for high-cost systems — is the only way to close the gap.

The home inspector works for you. But the inspection they perform is governed by standards that define what they must check and what they’re allowed to skip. Knowing the difference before you close is cheaper than discovering it after.
