A missing inspector, a crawlspace adventure, and an unexpected plumbing leak became a reminder that some of the most important parts of a home are the parts homeowners rarely see.

A few weeks ago, I was sitting in a living room with some sellers while their pre-listing inspection was taking place. The inspector had gone into the crawlspace, and after quite a while we realized we hadn't seen him come back out. At first, we laughed about it, but after calling for him several times and getting no response, we started to wonder if we should check on him.

We walked around to the crawlspace entrance and called again. Nothing. I called his phone twice and still didn't get an answer. We looked around the house for another access point but couldn't find one. Finally, I did something that probably wasn't in any real estate training manual. I crawled under the house.

My seller, who is 76 years old, crawled in behind me.

Now we had a missing inspector, a homeowner, and a Realtor all under the same house trying to figure out where everyone was. As we worked our way through the crawlspace with flashlights, we discovered something that no one expected. There was water under the house beneath the primary bathroom. Quite a bit of it.

The crawlspace had recently been encapsulated, so naturally my seller became concerned. We continued looking for the inspector while also trying to understand where the water was coming from. Eventually, the homeowner's wife was able to locate the inspector from another access point near the garage. He was perfectly fine and had simply been doing a very thorough inspection.

As it turned out, he believed that a recently installed dehumidifier may have led to a plumbing pipe being bumped or loosened, creating a leak beneath the bathtub area. Suddenly, finding the inspector wasn't the biggest issue anymore. The water under the house had everyone's attention.

Eventually we all made it back outside, although I think my seller's back was questioning his decision to follow me under the house. As we stood there talking, I realized how common this situation really is. Most homeowners spend a great deal of time taking care of what they can see. They paint walls, replace flooring, update kitchens, mow grass, and pressure wash driveways. But very few people ever think about what is happening underneath their home.

The truth is that some of the most important systems in a house are hidden in a crawlspace. Plumbing lines, ductwork, electrical connections, insulation, dehumidifiers, and structural components all live there. If something begins to fail, homeowners often have no idea until an inspector discovers it.

Over the years, I have seen standing water, fallen ductwork, damaged insulation, rodent activity, moisture issues, electrical concerns, and even a dehumidifier that had caught fire. In most cases, the homeowner had no idea there was a problem because nothing inside the house appeared wrong.

One of the assumptions many of us make is that if everything inside the home feels fine, then everything underneath must be fine too. Unfortunately, crawlspaces don't always work that way. Problems can quietly develop for months or even years before they become visible.

That is one reason I encourage my sellers to have pre-listing inspections. I would much rather discover an issue before a buyer does. A small leak, a loose duct, or a moisture problem is usually easier to address when you find it on your own timeline rather than during negotiations.

I am certainly not recommending that homeowners crawl under their houses looking for inspectors. After this experience, I think we've all agreed that wasn't our finest moment. But I do think homeowners should be aware that one of the most important parts of their home is often the part they never see.

Sometimes the difference between a simple repair and an expensive surprise is simply knowing what is happening under your house before someone else discovers it for you.
