"But the Home Inspector Should Have Found That"

If you work in real estate long enough, you will hear it. A contractor opens up a wall six months after closing, finds something ugly, and says it to the new homeowner with total confidence:

"Your home inspector should have caught this."

It sounds authoritative. It feels like an answer. And nine times out of ten, the person saying it has never read a home inspection Standards of Practice, has never performed a home inspection, and could not tell you where a home inspector's job begins or ends. As a Certified Master Inspector, I want to unpack why this phrase causes so much confusion, what a home inspection actually is, and why professionals in every trade, mine included, should be careful about speaking with authority on someone else's profession.

What a Home Inspection Actually Is

A home inspection is a visual, non invasive examination of the readily accessible systems and components of a home, performed on a single day, under the conditions present that day. That is not my personal definition. It is the foundation of the Standards of Practice published by both ASHI and InterNACHI, the two major professional bodies in this industry, and it is echoed in licensing language across the country.

Every word in that definition is doing work.

Visual means we report on what can be seen. We do not open walls, lift flooring, dismantle furnaces, or excavate around foundations.

Non invasive means we do not cause damage to find problems. The seller still owns that house on inspection day. I cannot cut a hole in their drywall on a hunch.

Readily accessible means if a crawlspace hatch is screwed shut, an attic is buried under the seller's storage, or a panel is blocked by a freezer, those areas get documented as inaccessible, not inspected by X-ray vision.

On a single day means the inspection is a snapshot, not a warranty. A water heater that worked Tuesday can fail Friday. A roof that was dry during a drought can leak in the first hard rain.

When a contractor demolishes a shower surround and finds rot behind the tile, they are looking at something I was never permitted, equipped, or contracted to see. They are comparing an invasive teardown to a visual inspection and calling the difference a miss. That is not a fair comparison. It is two entirely different scopes of work.

Generalists by Design

Here is something many people outside the profession do not realize. Home inspectors are generalists on purpose. In a single inspection I evaluate the roof, structure, electrical, plumbing, HVAC, insulation, ventilation, exterior, interior, and built in appliances. No other professional walks a property with that breadth of scope in a few hours.

The tradeoff for breadth is depth. The plumber who works on drain lines all day knows drain lines more deeply than I ever will. The roofer who tears off thirty roofs a summer knows shingles more deeply than I ever will. I am not threatened by that. It is the entire reason inspection reports say things like "It is advised that a qualified contractor further evaluate." The inspection identifies the symptom and routes the client to the right specialist. That is the system working exactly as designed.

But that street runs both ways. The roofer who knows shingles deeply does not know my Standards of Practice. The plumber who knows drain lines does not know what was accessible on inspection day, what the conditions were, or what my report actually said. Speaking confidently about whether an inspector "should have caught" something requires knowing all three, and the contractor standing in the demolished bathroom knows none of them.

Why Inspectors Cannot Just "Say More"

Buyers sometimes ask why inspectors hedge, why we defer, why we will not just tell them what the repair will cost or whether the furnace has five good years left. The honest answer is that saying more than we know is how inspectors get sued, and worse, it is how clients get hurt.

If I estimate a repair cost and the real number comes in triple, I have anchored my client to bad information. If I guess at the age of a system instead of reading the data plate, I have guessed with someone's largest purchase. If I diagnose the cause of a foundation crack instead of reporting the crack and deferring to a structural engineer, I have practiced engineering without a license. Every one of those statements feels helpful in the moment. Every one of them is a liability for me and a disservice to the client.

Professional discipline in this field is not about doing less. It is about knowing precisely where my expertise ends and saying so out loud. The most dangerous inspector in the business is not the cautious one. It is the one who never met a question he would not answer.

The Same Standard Applies to Everyone

And this is the heart of it. The discipline I just described should not be unique to home inspectors. No professional should publicly assess another professional's performance in a field that is not their own, based on partial information, in front of that professional's client.

I hold myself to this. When I find amateur looking wiring, my report describes the condition and advises evaluation by a licensed electrician. It does not say "the electrician who did this was incompetent," because I did not watch the work get done, I do not know what the electrician was hired to do, and electrical contracting is not my license. I extend that courtesy because it is accurate, because it is professional, and because someday a contractor will be standing in a basement I inspected, and I hope they extend it back.

What does the alternative sound like? It sounds like a contractor telling a homeowner their inspector missed something behind a finished wall. It sounds like an inspector telling a buyer the previous HVAC tech botched an install he never witnessed. In both cases, a professional borrows credibility from their own field and spends it in a field where they have none. The homeowner walks away with a grievance instead of an understanding, and trust in everyone gets a little cheaper.

The better script is simple and takes ten seconds: "I found this once we opened things up. It would not have been visible during a standard inspection, but it does need to be addressed. Here is what I recommend." Accurate. Professional. Helpful. Nobody's reputation used as a prop.

What Homeowners Should Take From This

If a contractor ever tells you your inspector missed something, ask two questions before you accept it. Was this visible and accessible on the day of the inspection? And what does the inspection report actually say? Pull the report. Very often you will find the symptom was noted, the limitation was documented, or the area was flagged as inaccessible. Sometimes you may find a genuine miss, because inspectors are human, and a good one will own that conversation directly. But the report and the Standards of Practice are the measuring stick, not a comment made over an open wall.

Here is the plain truth that every Standards of Practice, every inspection agreement, and every honest inspector will tell you. We will not find every issue in a home, and we are not required to. It would be an impossible task. A house contains thousands of components, hidden assemblies behind every wall and under every floor, and conditions that change with the weather, the seasons, and simple use. No visual inspection performed in a few hours could ever uncover all of it, and no standard in the industry asks us to. What the inspection does is identify visible, significant deficiencies in accessible areas at a single point in time, and that alone routinely saves buyers from expensive surprises.

A home inspection is one of the best risk reduction tools available to a buyer. It is not a guarantee, not a warranty, and not a crystal ball, and no honest inspector has ever claimed otherwise. Understanding what it is, and what it is not, protects everyone in the transaction, including the contractor who shows up six months later.
