Stop Worrying About Your Crawl Space

THIS SIMPLE TOOL PUTS THE POWER BACK IN YOUR HANDS

You know what's frustrating?


Taking your car to a mechanic when you don't know anything about engines.


You're sitting there, completely at their mercy, hoping they're giving you straight talk about what really needs fixing.


Well, that's exactly how most folks feel when a crawl space contractor shows up at their house.


But here's the thing - it doesn't have to be that way.


What if I told you there's a simple tool, cheaper than dinner for two at Halls Chophouse, that could tell you exactly what's going on under your house?


Because there is, and I'm kind of surprised I haven't talked about this sooner.

Welcome to Crawl Logic Lowcountry!


The Game-Changing Tool

Here it is: a two-pin moisture reader. You can grab one at Lowe's for less than thirty bucks. This little device is honestly the single most important tool any Charleston homeowner can have for monitoring their crawl space health.



Quick tip if you're getting the Lowe's version - make sure it's set to "wood" and the letter "C" (unless you've got a historic home). That "C" setting is for soft woods, which is what your crawl space is almost certainly built with. This simple setup is all you need to know exactly what's happening under your house.


Think about it - these crawl space solutions we install can cost thousands of dollars. They're expensive, they can be loud, and sometimes they come with a distinct smell. Wouldn't you rather know for sure if you actually need any of that before making that investment?




How to Use It

Look, this isn't rocket science - and that's exactly why I love this tool. You're looking for one magic number: 16%. If your readings are under 16% everywhere in your crawl space, congratulations! You don't need anyone or anything. It's really that simple.



Just stick those two pins into your floor joists and subfloor in different spots. Check a few different areas - especially any spots that worry you. And here's a pro tip: make it part of your regular home maintenance. Check every few months, just like you'd change your air filters. It takes maybe 15 minutes, and it could save you thousands.

Real World Example

Just today, I got a call from a guy who recognized me from Housing BJJ (great gym on Long Point Road, by the way - best kids' program in the state, but that's another story). He was worried about his crawl space, had been watching our videos, and wanted me to take a look.



His house is about 10 years old, open air with lattice. Pretty standard Charleston setup. I went in there with my moisture reader, and guess what? Every spot I could reach was showing 15.6% to 16.2%. With the dry season coming up, those numbers are only going to get better.


Instead of selling him an expensive encapsulation system, I told him the truth: just remove the insulation yourself on a Saturday. Save the money we'd charge you for that simple job. Keep checking with your moisture reader every few months. If it stays under 16%, you're golden.

When to Take Action

Now, don't get me wrong - sometimes you do need professional help. If you're consistently seeing readings over 16%, that's when you should start thinking about solutions. But here's the key: you're making that decision based on actual data, not just someone's sales pitch.



Remember, Charleston's humidity changes with the seasons. What might look like a problem in our sticky summers might naturally resolve as we head into drier months. That's why regular monitoring is so important. It helps you understand what's normal for your house and what's actually cause for concern.

The Only Way Forward

Listen, I'm probably not supposed to tell you how to avoid hiring us. But here's the thing - I'm building my first house right now, and you know what's in my toolkit? A two-pin moisture reader. Because knowledge is power, and I'd rather see you spend $30 on a tool that helps you make informed decisions than thousands on work you might not need.



Think about it this way: if you're dealing with actual moisture issues, we'll still be here to help. But wouldn't you rather know for sure? Wouldn't you rather have real data backing up that decision? That's what this simple tool gives you - the power to know what's really going on under your house.


So here's my advice: head to Lowe's, grab yourself a moisture reader, and start checking your crawl space. If you're under 16%, sleep easy. If you start seeing higher numbers, or if you're not sure what you're looking at - that's when you give us a call. We'll give you the same straight talk I gave the guy from my BJJ gym: either you need help, or you don't. No sales pitch, just facts.


Because at the end of the day, this isn't about making quick money. It's about helping Charleston homeowners make smart decisions about their homes. And sometimes the smartest decision is spending $30 instead of $3,000.

So here's something you don't see every day: I'm about to show you a crawl space that isn't technically a crawl space at all. It's the entire area underneath a pool. And let me tell you, this was some of the hardest work I've ever done. If there was an award for crawl space poly work, I'd be putting this job up for it.

Got a call today to head back to a job we finished about two or three months ago. Now, before you think something went wrong with our work, let me explain what actually happened. This was a new construction project - we've been doing a lot of work with custom home builders lately, which has become a nice niche for us.

I got a call recently from a potential customer who'd already talked to another crawl space company. She told me they said hundreds of gallons of water were flowing into her crawl space. When I asked if they said "maybe" or "we think" or anything like that, she said no - they told her it was a fact. Hundreds of gallons
