What Happens When You Skip Crawl Space Maintenance

Introduction

A Real Spring Hill Story

WHY YOUR ENCAPSULATION NEEDS ANNUAL ATTENTION

I was out in Spring Hill yesterday working on a crawl space we encapsulated four years ago.


The homeowner called because his dehumidifier was throwing an error code.


When I got there and pulled the filter, I understood why.


Three years of dust, debris, and neglect had turned it into a solid block.


Here's the thing - we did his first annual maintenance right on schedule.


Then he declined service for the next three years. I get it.


Everything seemed fine.


The crawl space looked good. Why spend money on maintenance when nothing seems broken?


This is exactly why I'm sharing this story.


Because a lot of homeowners think crawl space encapsulation is a one-time fix.


Install it and forget about it.


But that's not how it works, and this Spring Hill job is a perfect example of what happens when you skip maintenance.

The Background Story

Four years ago, we installed a complete encapsulation system for this homeowner. New vapor barrier, drainage system, and a quality dehumidifier to keep everything dry. The first year, he scheduled his annual maintenance like clockwork. We came out, checked the system, replaced the filter, made sure everything was running properly. The crawl space looked great.



Then year two came around, and he declined the service. Same thing happened in year three and year four. No maintenance calls, no filter changes, nothing. The dehumidifier kept running, so from his perspective, everything was fine.


Until it wasn't. The error code popped up on his sensor. That's when he called us back. Lucky for him, he had that sensor. Without it, he would've had no idea his dehumidifier had stopped working. And a dehumidifier that's not working means moisture builds up, which defeats the entire purpose of encapsulation.

What We Found

When I pulled that filter, it told the whole story. Three years of operation without a single cleaning or replacement had completely clogged it. The dehumidifier was basically trying to pull air through a wall. No wonder it threw an error code.



The good news? We caught it before any real damage happened. The sensor alerted the homeowner, and he called us right away. We swapped in a new filter, cleared the error code, and the unit fired right back up. Running perfectly.


But here's what could've happened without that sensor: the dehumidifier would've just stopped working, and he wouldn't have known. Moisture would've started building up again. All that money spent on encapsulation would've been wasted because the equipment wasn't doing its job.

Why Dehumidifiers Need Maintenance

Think about your HVAC system for a minute. You change those filters regularly, right? Your crawl space dehumidifier works the same way. It's constantly pulling air through a filter to remove moisture from your crawl space. That filter catches dust, debris, and everything else floating around down there.



Over time, that filter gets clogged. When it's clogged, the dehumidifier can't pull air through properly. It works harder, runs less efficiently, and eventually throws an error code or just stops working altogether. In this case, three years of buildup basically shut the whole system down.


Your encapsulation system isn't magic. It's equipment that needs regular attention, just like your furnace, your water heater, or your car. Skip the maintenance, and you're asking for problems.

The Real Cost of Skipping Maintenance

Here's what this homeowner got lucky with: his sensor caught the problem early. A new filter and a service call got everything back on track. But let's talk about what could've happened.


Without that sensor, the dehumidifier could've been off for months without him knowing. Moisture would've built back up in the crawl space. That moisture leads to mold, wood rot, and all the problems encapsulation is supposed to prevent. Suddenly, you're looking at thousands of dollars in repairs on top of the original encapsulation investment.


Compare that to the cost of annual maintenance. One service call per year to make sure everything's running right. It's the difference between protecting your investment and watching it fail. This homeowner sees the value now. He's back on our yearly maintenance schedule.

What Annual Maintenance Includes

When we come out for annual maintenance, we're not just changing a filter and leaving. We check the entire system to make sure everything's working the way it should.



Filter inspection and replacement is the big one. We look at how dirty it is, swap it out if needed, and make sure air is flowing properly. We test the dehumidifier to verify it's pulling moisture like it should. We check the sensor to make sure it's reading accurately. And we look around the crawl space itself to catch any issues before they become problems.


It's a straightforward process, but it makes all the difference in keeping your system running right.

Signs Your System Needs Attention

Between annual visits, there are a few things you should watch for. Error codes on your sensor are the obvious one - that's your system telling you something's wrong. If you notice humidity levels creeping up, that's another sign your dehumidifier might not be working properly.



Unusual sounds coming from the unit, musty smells in your home, or visible moisture in the crawl space are all reasons to call before your scheduled maintenance. The sensor helps catch most issues, but it's good to know what to look for yourself.

It's December in Chattanooga. Cold weather is here. And you know what that means - mice and rats are looking for somewhere warm to spend the winter. If you've had your crawl space encapsulated, you might think you're all set. Nice sealed space, moisture controlled, everything protected. But here's something most
