The Crawl Space Mistake That's Costing Knoxville Apartment Owners Thousands
When Crawl Space Work Goes Wrong
WHAT A 6,000 SQUARE FOOT DISASTER LOOKS LIKE
I'm out here at an apartment complex in Knoxville, and the more I crawl around, the worse it gets.
Someone already paid to have this crawl space "fixed."
They've got vapor barrier down, they've got drainage installed, they've even got support jacks in place.
But none of it's working. Actually, it's worse than not working - some of this stuff is actively causing problems.
Now this property owner is looking at paying again to fix what should've been done right the first time.
And because the first crew did such a terrible job, the repair bill is going to be way more than proper encapsulation would have cost from the start.
This is a 6,000 square foot crawl space.
We're talking about weeks of work and a massive bill to undo the damage and actually solve the problems.
Let me show you what went wrong and why it matters.
The Support Jack Disaster
Support jacks are supposed to stabilize your floor joists when they're sagging or damaged. They're literally holding up your floor.
So when you install a support jack, you need solid, stable lumber underneath it. Usually that means a beam made from engineered lumber or multiple boards laminated together - something that's not going to shift or warp.
What did they do here? They installed jacks on single two by sixes.
And because this crawl space has major moisture problems, those two by sixes are warped. I mean seriously warped - they look like strips of bacon. Curved, twisted, completely compromised.
So now you've got support jacks that aren't supporting anything. They're sitting on warped lumber that's moving and flexing. That means the floor joists they're supposed to be holding up are still sagging, still damaged, still causing problems upstairs.
We're going to have to sister those joists - which means attaching new lumber alongside the damaged ones to reinforce them. That's extra time, extra materials, and extra cost that wouldn't have been necessary if they'd just done the jacks right in the first place.
The Standing Water Problem After "Repairs"
Here's how you know crawl space work failed - there's standing water everywhere.
Not just a little moisture. We're talking water pooling on top of the vapor barrier, water sitting along the foundation walls, visible water stains showing this has been an ongoing problem.
If you've got standing water on top of your vapor barrier, that means water is coming up from below and the barrier isn't sealed properly. Or it means you've got drainage problems that were never addressed. Either way, the encapsulation didn't work.
The water stains on the walls tell me this isn't new. This has been happening for a while, probably since right after they "fixed" it.
When you do crawl space encapsulation right, you shouldn't have standing water. Period. The whole point is to control moisture and keep water out. If water's pooling after the work is done, something major was missed or done wrong.
In this case, it's pretty clear what happened - they put down a vapor barrier and called it done without actually addressing where the water was coming from or how to get it out.
The Drainage System That Doesn't Work
So they did install drainage. That's something, right?
Except they didn't bury it. They just laid the pipe on the ground and covered it with gravel.
Let me explain why that doesn't work. Drainage pipes need to be buried in a trench at the lowest point of your crawl space so water naturally flows to them. Then the water enters the pipe through perforations and gets routed to your sump pump.
When you just lay a pipe on top of the ground and throw gravel over it, water isn't going to magically find its way into that pipe. It's going to sit there and pool, exactly like it's doing in this crawl space.
You can see the pipe right there above ground, just sitting under a layer of gravel. It's not doing anything. It's not catching water, it's not routing water anywhere. It's just... there.
This is what I call a cover-up job. It looks like they did something if you don't look too close. But it's not actually functioning. And now we're going to have to dig proper drainage trenches, bury the pipes correctly, and install sump pumps that actually work.

The Real Cost of Bad Crawl Space Work
So let's talk numbers. I don't know exactly what this property owner paid for the original work, but based on the size and what was supposedly done, I'd guess several thousand dollars minimum.
And what did they get for that money? Nothing. Actually worse than nothing - they got problems that are now more expensive to fix.
Here's what we're looking at to actually fix this 6,000 square foot crawl space:
Sistering floor joists to repair the structural damage from those failed support jacks. Pulling out all the incorrectly installed drainage and digging proper trenches. Installing new drainage systems with pipes actually buried where they need to be. Multiple sump pumps because of the size of the space. Multiple dehumidifiers to handle moisture control across 6,000 square feet. Cleaning out all the standing water and failed materials.
This is going to take weeks. And it's going to cost way more than proper encapsulation would have cost if they'd done it right the first time.
That's what happens when you go with the cheapest bid or hire someone who doesn't actually know crawl space work. You pay once for work that doesn't work. Then you pay again - usually a lot more - to fix it right.
Why This Happens (And How to Avoid It)
So how does work this bad happen in the first place?
Sometimes it's contractors who genuinely don't know any better. They think laying drainage on the ground is fine. They don't understand why support jack bases matter. They've never been trained properly on crawl space encapsulation.
Other times, it's contractors who do know better but cut corners anyway. Maybe they're trying to save time. Maybe they're trying to come in under budget and pocket the difference. Either way, the property owner ends up with a mess.
Here are some red flags to watch for: A bid that's way cheaper than everyone else's. Contractors who can't explain exactly what they're doing and why. Anyone who rushes through the inspection without spending real time in the crawl space. Crews that show up and finish impossibly fast.
Questions you should ask before hiring anyone: How do you install support jacks and what do you use for the base? Where exactly will you place the drainage and how deep will you bury it? How will you handle moisture control in a space this size? Can you show me pictures of similar jobs you've completed?
The cheapest bid almost always costs the most in the end. Because you're either getting inexperienced work or corner-cutting work, and both end up needing to be redone.
