Which is Better: Slab or Crawl Space?

Are you building anytime soon? Well, there will be a lot of things you will need to decide before you finally get the project running. But one thing that needs to get out of the way right from day one is the foundation. 

As you know, there are many different types of foundations. Whatever choice you make will be determined by your construction budget, soil type on your property, climatic conditions in your area, and a host of other factors. 

In this post, we will be looking at the slab vs crawl space debate, giving you additional information to help you make an informed choice.

What’s the Difference Between Slab and Crawlspace? 

Before we get into the slab vs crawl space cost implications, it’s important to first of all understand the difference between the two. 

A slab foundation is as basic as it sounds. It’s basically a concrete slab upon which the house will be built. Slab foundations often involve additional steel columns for support. 

Crawlspace foundations, on the other hand, leave space between the foundation and the home’s first floor. Concrete pillars are normally used to support the walls but instead of filling the foundation with concrete, you just start working on your first floor right away.

Understanding the Costs of Slab vs Crawlspace 

Slab foundations are very different from crawlspace ones. This means that they will typically cost differently as well. 

Every debate on slab vs crawl space foundation tends to always prioritize the cost, and it’s not hard to see why. Most people are always tight with their construction budgets and will go for the most affordable workable option they can find. 

  • For the slab foundation, you will need materials worth $3,500 for the entire project. Additional labor costs will also be required, hitting around $7,000. At the end of the day, it will cost you around $10,500 to install a slab foundation. 

  • Crawlspace foundations on the other hand will require materials worth around $5,000. The labor cost will reach up to $12,500, bringing the total foundation costs to $17,500.

Remember that all these costs are also based on the assumption that you’re building a 1,500 square foot home.

Durability Considerations 

One thing you need to keep in mind while analyzing the slab vs crawl space pros and cons is durability. After all, if you are going to invest thousands of dollars on a foundation, you want to be sure you will get value from every buck. 

Before we get to the specific pros and cons, it’s important to note that both slab and crawlspace foundations will last for ages. If installed correctly, these foundations will serve you for almost 50 years. 

The Pros and Cons of Slab and Crawlspace Foundations 

  • Slab foundations can easily crack with shifts in the soil below or growth of roots around them. On the plus side, they are super strong and would easily hold a lot of heavy furniture. 

  • Slab foundations are also easier to build and take less time compared to crawlspace. They are very energy efficient and would require very little maintenance once they are put up. 

  • Slab foundations are hard to inspect and they don’t give you space below for AC units, water pipes, and other elements a home needs. Besides, the floor will always feel harder on your feet. 

  • Crawlspace foundations are more susceptible to termites and can easily be compromised in the event of flooding. They also take longer to build and are far less energy efficient. But despite this, these foundations are perfect for homes on sloping ground. They are also easier to inspect and offer you a lot of room below for plumbing. This gives you outstanding versatility in the long run.
