Why I Changed Everything About How We Light Crawl Spaces

Why Your Crawl Space Needs Better Lighting

In crawl spaces, shadows hide problems

Sometimes the biggest lessons come from unexpected places.


For me, it was a jiu-jitsu gym in Tennessee that changed how I think about crawl space lighting.



Sounds weird, right? But hear me out.


I'd been working in crawl spaces for years, thinking I knew everything there was to know.


Then I saw something that made me completely change how we do things at Crawl Logic.


It wasn't just about better lighting - it was about treating these spaces with the respect they deserve.

Welcome to Crawl Logic Lowcountry!


The Old Way Wasn't Working

Let me paint you a picture of how most companies still handle crawl space lighting.


They either use bright flood lights that create harsh shadows, or they rely on headlamps that only light up whatever you're looking directly at.


It's like trying to inspect an entire house by looking through a keyhole.


I remember this one job that really drove the point home.


We were called to fix a two-year-old encapsulation that had completely failed.


The whole thing was a mess - mold everywhere, everything falling apart.


And you know what made it even worse? All those problems had been hiding in the shadows for months because nobody could see them properly.


When you're working with flood lights, you get these super bright spots and pitch-black areas right next to each other.


Miss one small problem in those dark spots, and six months later, you've got major issues.


That's exactly what happened with that failed encapsulation job.


By the time anyone noticed, it was too late.




The Light Bulb Moment

Meeting that contractor in Tennessee changed everything.


Instead of setting up temporary lights or relying on headlamps, he treated the crawl space like a real construction site.


Before starting any work, he installed proper overhead lighting throughout the space.


Simple, right? But I'd never seen anyone do it this way.


It hit me right then - we'd been doing it wrong all these years.


Real construction sites have proper lighting because you need to see what you're doing.


Why should crawl spaces be any different? After all, what's under your house is just as important as what's above it.

Why Proper Lighting Matters For Your Home

Think about it - would you hire a mechanic who works on your car in the dark? Of course not.


So why let someone work under your house without being able to see properly?


Good lighting means:



  • We catch small problems before they become big ones
  • Every seam and corner gets proper attention
  • Nothing gets missed or rushed
  • Future inspections are easier
  • Any contractor who needs to work under there later can see what they're doing

Our Lighting Approach Today

At Crawl Logic, we don't just bring lights - we install them.


Every crawl space gets 10-20 overhead lights as standard.


It's not optional, and it's not an upgrade.


It's just how work should be done.



This isn't about being fancy. It's about doing the job right.


When we can see everything clearly, we can guarantee our work.


That's not just better for us - it's better for your home.

Quick Facts About Crawl Space Lighting

Here's what you need to know about proper crawl space lighting:


Red Flags to Watch For:


  • Companies using only headlamps
  • Single flood light setups
  • "We'll bring lights if we need them"
  • Dark corners and shadows
  • Rush jobs because "they can't see well"


Smart Questions to Ask:


  • How do you light up the crawl space?
  • Will you install permanent lighting?
  • Can I see examples of your lighting setup?
  • How will I check the space later?

I was just out at a high-end project on Sullivan's Island, setting up lighting for a crawl space encapsulation. The number of lights we brought might seem like overkill, but here's something that might surprise you: on a $15,000 crawl space job, proper lighting only costs about $150. Yet when we tell customers it's non-negotiable, they often ask if we can skip it to save money.

You might be surprised to learn that nearly a third of our business at Crawl Logic comes from fixing other companies' crawl space work. Actually, if you've dealt with crawl space companies before, maybe you wouldn't be surprised at all.

Here's a shocking number for you: 20% of the encapsulated crawl spaces I inspect have failed because of one small device that was supposed to make everything easier. I'm talking about condensate pumps, and if you've got one under your Charleston home right now, you might want to keep reading.
