You Should Know Exactly What's Under Your House

Introduction

What's Hiding Under There Could Be Costing You More Than You Think

MOST HOMEOWNERS HAVE NO IDEA WHAT THEIR CRAWL SPACE LOOKS LIKE — AND SOME COMPANIES COUNT ON THAT

I found something recently that stuck with me.


A homeowner had hired a crawl space company — not us — because they could do it cheaper. Reasonable decision. Most people shop that way.


But when I got under that house, here's what I found.


The dehumidifier discharge line was dumping water directly under the plastic. The unit that was supposed to pull moisture out of the crawl space was pumping it right back in. And it had never been serviced. Not once.


The foundation vents? "Sealed" with spray foam used as glue. Still wide open. Outside air coming in freely.


Mold everywhere. Mice. No rodent proofing.


This wasn't a crawl space that had been encapsulated. It was a crawl space that looked like it had been encapsulated. There's a big difference.

The Problem With Invisible Work

Here's the thing about crawl spaces — you don't walk past them every day. You can't glance over and notice something's off. Bad work can hide under your house for a year or two before you see a single sign of it.


Some companies know that.


They know that once the crew packs up and the invoice is paid, nobody's checking. So corners get cut. Units don't get plugged in. Vents get "sealed" in thirty seconds with a can of spray foam. And the homeowner has no idea — because why would they?


Nobody told them what done right was supposed to look like.

  • The ceiling of a basement with a lot of pipes and insulation.

  • A basement with a lot of insulation and a light on the ceiling.

  • A basement with a lot of pipes and columns

  • An empty basement with a wooden ceiling and white walls.

What You Actually Deserve

When a crawl space job is done right, you should be able to see it.


Not take someone's word for it. Actually see it.


Before we finish any job, I walk every inch of that crawl space with a 4K camera. You get a full before and after — every corner, every vent, every inch of liner, the discharge line, the dehumidifier. Everything.


You see it at your kitchen table before you pay a single dollar.


The vents are sealed — properly, not with a bead of spray foam holding a cover that's still open to the air. The discharge line runs where it's supposed to run. The dehumidifier is running, connected, and doing its job. You leave with a moisture reader so you can check on your crawl space any time you want.


And a year from now, I come back to service the unit. Because a dehumidifier that nobody maintains is just expensive equipment waiting to fail.


That's what done right feels like. You know what's under your house. You've seen it. You paid for it because you were satisfied — not because someone handed you an invoice and disappeared.

Before You Hire Anyone, Ask This

Ask them if you'll see the finished job before you pay.


Ask them who comes back to service the unit.


Ask them what happens if something isn't right.


If the answers are vague, that's your answer.

A Lower Price Shouldn't Mean Lower Standards

There's nothing wrong with wanting to save money on crawl space repairs. It's a big investment, and you should feel comfortable with what you're spending.


But two companies can give you quotes for the same job and have completely different plans for how they'll do it.


One might include proper drainage, sealed foundation vents, rodent proofing, and a dehumidifier that's installed correctly. Another might leave some of those details out to bring the price down.


That's why it's important to understand exactly what's included in your quote.


Ask questions. Look at the materials they're using. Make sure you understand how the system will keep moisture out and what kind of maintenance it will need afterward.


A good contractor should be willing to explain their work before you agree to anything.

I was in a crawl space recently that stopped me in my tracks. Spray foam on the walls. Poly on the floor. Clean install. Solid workmanship. Honestly? It looked great.

You hired someone. You did the right thing. They came out, encapsulated the crawl space, installed a dehumidifier, and left. You wrote the check and got on with your life.

You spent real money on your crawl space. The crew came out, did the job, and drove away. And now it's done, right?
