The worst house inspector Aguiar says he has ever inspected was in Anaheim, in Orange County. It was a mobile home (manufactured home) whose main shower had been through a botched repair. With the house empty, everything was dry. But Aguiar has a habit of running every faucet, shower and toilet while he is in the space under the floor (crawl space) — and he found what he and the show's realtors nicknamed a "waterfall," coming down about three feet from the main electrical panel.

The case sums up the value of an inspection done right: the buyer would only have found the leak in the first shower, weeks after moving in. And it also shows why a report has to be read carefully — not everything in it carries the same weight.

What the colors mean

Most modern reports, generated on digital platforms, sort findings by severity, generally into three colors. The standard varies from company to company, but usually follows this logic:

• Red: a relevant defect or a safety risk — calls for a repair or evaluation by a specialist;
• Orange or yellow: an item that needs repair or maintenance, with no immediate urgency;
• Blue or gray: information, an observation or routine maintenance.

The point Aguiar makes a priority of explaining is that red is not a synonym for expensive. One example that comes up a lot: the gas outlet for the stove or dryer with no cap on it. If the appliance hasn't been installed yet, the line needs a cap, a plug that costs about three dollars. It's a red item because it's a serious risk: a child can open the valve thinking it's water, and a spark from a loose outlet is all it takes for an accident.

A $10 detail that saves lives

Another example Aguiar gives involves the gas water heater. The vent that carries combustion gases outside — including carbon monoxide, toxic and odorless — has to run upward from the unit; installation codes require a continuous rise in the connector. At a house inspected by an employee of another Orange County company, the vent ran flat, the problem was never written down, and the company had to file on its own insurance and pay for the repair.

In California, it's worth adding another basic item: the water heater must be strapped to the wall with seismic straps, a state law requirement so it doesn't topple in an earthquake and break the gas line.

A new house has defects too

Plenty of people think inspection is only for old houses. Aguiar says the opposite: on a 2026 build, he expects to find 10 to 15 findings. He has inspected a 1909 house in excellent condition and new houses with basic problems.

The most common ones he lists:

• Air conditioning ducts badly connected in the attic, leaking air — the engineer designs it, but the hookup is done by a subcontracted crew. The joke in the episode is that the work was done "on a Friday at 4 in the afternoon."
• Mislabeled breakers in the electrical panel. One of the show's realtors tells of an inspection at a new house where every label was wrong.

Aguiar also reports that some builders don't want the inspector going up into the attic, citing fall risk. His answer: send over the insurance policy and insist, because he has to protect his client.

The inspector doesn't estimate — and shouldn't scare anyone

Two limits of conduct come up in the conversation. The inspector should not say how much each repair costs: a number pulled out of the air frightens the buyer and can be wrong. Estimates come from a licensed contractor, and the negotiation with the seller stays with the agents. And the inspector cannot leave anything out — not even to "help" the sale go through.

The balance, for Aguiar, is explaining the real severity. Many findings are things the owner can handle "on a Saturday morning"; others, like replacing all the plumbing, are expensive and change the negotiation.

What's left out of the general inspection

A home inspection is visual and limited to accessible areas. Aguiar lists items he is not required to evaluate:

• the yard irrigation system (sprinklers);
• the water conditioner or whole-house filter (water softener);
• antennas;
• plumbing inside walls and underground, and the foundation beneath the concrete floor (slab), which can't be seen.

Beyond that, some evaluations are specialized and hired separately: termites (done by pest control companies, which usually inspect for free and sell the treatment), a camera down the sewer line, the roof by a roofer, the pool, the chimney, mold and a structural engineer when there is a sign of a foundation problem. A good report tells you when it's worth calling each specialist.

How to use the report

• Read the red items first and separate cheap safety fixes from big repairs.
• Get estimates on the relevant items while you are still within the contingency window.
• Negotiate on the basis of data: a repair request, a credit at closing or a price reduction.
• Keep the report. Even if you walk away from the house, it helps you compare properties; if you buy, it becomes your maintenance plan.
