The Real Cost of Improper Jack Installation: What I Found During a Nashville Home Inspection
Introduction
Seen During a Real Estate Inspection
WHAT $20,000 SHOULD NEVER BUY YOU
During a recent real estate inspection in Nashville, I found something that really bothered me.
The homeowner had spent between $15,000 and $20,000 on floor jacks from one of those big corporate companies.
That's a lot of money for work that wasn't done right.
Let me be clear - when we're talking about your home's structural support, there's no room for cutting corners.
This isn't just about following rules or regulations.
It's about making sure your home is properly supported and safe for your family.
The Basics of Proper Jack Installation
Here's what proper floor jack installation should look like: You want support jacks every 4 to 5 feet. That's not just a number I made up - it's the industry standard that ensures your floor gets the support it needs. Think about it like fence posts - space them too far apart, and the fence starts to sag. Your floor works the same way.
Even with precast footers (those are the concrete pads the jacks sit on), proper spacing is crucial. You can have the most expensive jacks in the world, but if they're not spaced right, you're not getting what you paid for.
Each jack needs to be:
- Properly spaced (4-5 feet apart)
- Correctly leveled
- Securely positioned
- Installed on appropriate footers
- Aligned with the floor's support structure
What I Found
Let me paint you a picture of what I discovered under this Nashville home. Instead of jacks every 4-5 feet, these were spaced 7-8 feet apart. That's nearly double the distance it should be. And remember - this homeowner paid $700-900 per jack, with about 20 jacks total.

Do the math: that's $15,000 to $20,000 for improper installation. They even charged extra for those metal plates, which wouldn't be necessary if the jacks were spaced correctly in the first place. This wasn't just one or two jacks installed wrong - this was a systematic problem throughout the entire crawl space.
The Big Company Problem
Here's something you need to know about these big three-letter companies in Nashville: they're often more focused on making the sale than doing the job right. I know because I used to work for them. They train their salespeople to push for big numbers, but they don't always train their installers to do quality work.
What typically happens is this: A commission-based salesperson comes out, shows you some pre-recorded videos on their laptop, and quotes you a big number. They might throw around impressive-sounding titles like "foundation specialist" or "structural expert." But when it comes to the actual installation, corners get cut.
In real estate transactions like this one, these problems often don't show up until a home inspector takes a look. By then, the company has been paid, and the homeowner is left dealing with the consequences.
How to Protect Yourself
Listen, I'm not telling you this to scare you. I'm telling you because an informed homeowner is a protected homeowner. Here's what you need to know before anyone installs floor jacks in your home:
First, ask about spacing. If they can't give you a clear answer about why jacks need to be 4-5 feet apart, that's a red flag. Second, get everything in writing - including the exact number of jacks and their planned locations. And finally, ask for documentation. At Crawl Logic, we take detailed photos and videos of every installation. Any company confident in their work should do the same.
The Real Estate Impact
Here's why this matters, especially in real estate: Structural issues found during home inspections can derail a sale or force major price negotiations. That $20,000 jack installation? It might need another $10,000 in corrections to meet proper standards. That's not counting the stress and time lost dealing with the problem.
The good news is that properly installed floor jacks can last decades and add real value to your home. The bad news is that poorly installed ones can cost you twice - once for the initial installation, and again for the corrections.
Proper Installation Investment
When we install floor jacks at Crawl Logic, we do it right the first time. Yes, proper installation takes more time and materials. But wouldn't you rather pay once for work that's done correctly than twice for work that isn't?
Quality installation means:
- Correct 4-5 foot spacing
- Proper leveling and alignment
- Thorough documentation
- Owner verification of work
- Long-term structural stability
