Cost To Build A Crawl Space Foundation

A crawl space foundation is a type of foundation that is made up of a series of horizontal beams and posts, which provide support for the floor and walls. This type of foundation is usually constructed in areas where the ground is too difficult to dig into or where soil conditions make it difficult to build on top. Crawl space foundations are typically made from wood or concrete.

Crawl space foundations are a popular foundation type, but they come with their own set of challenges. In this post, we’ll discuss how much it costs to build a crawl space foundation and what you should consider if you’re hoping to DIY it or hire a contractor. We’ll also delve into the various types of foundations (including slab) so that you can make an informed decision about the best type for your home.

How Much Does It Cost To Build A Crawl Space Foundation?

The cost of a crawl space foundation is directly related to the scope of your project. For example, if you’re building a new home on a concrete slab foundation, it will cost more than if you’re simply adding a crawl space under an existing house. Some factors that affect the price include:

  • The type of soil in which you’re digging the trench for drainage pipes
  • The size and shape of your crawlspace
  • Whether or not landscaping needs to be done around it

What Is A Crawl Space Foundation?

A crawl space foundation is a type of foundation that is built below the ground level. This type of foundation can be used for houses, garages and other structures. It’s often used in areas where there isn’t enough space for a full basement.

Cost To Build A Crawl Space Foundation

There are many factors that can affect the cost of your crawl space foundation project, including:

  • Size and complexity of your crawl space. A large, complex crawl space is going to be more expensive than a smaller and simpler one.
  • Size and complexity of your home. Customized materials can increase construction costs, often by hundreds or thousands of dollars per square foot.
  • If you live in an area with harsh winters like Colorado, Iowa, or Maine — those extra months of snow removal will add up.

Installation Costs

The installation costs of a crawl space foundation can vary widely depending on the size of your crawl space, the type of foundation, and the materials used. If you do some of the work yourself it will lower your overall cost.

The cost for a standard foundation installation is about $10-$15 per square foot. This does not include excavation or concrete work needed to frame for an above-grade floor system such as poured walls, studs and joists (13).

What’s The Difference Between A Basement, Crawlspace, and Slab Foundation?

You’ll need a foundation for your home. But what kind? Basement foundations are more expensive to build than crawl space or slab foundations and should only be chosen if you really have no other option. A crawl space foundation is much cheaper to build than a basement foundation and should always be considered as an alternative for homeowners on a budget.

A basement is located below ground level, which means it has to be dug out with shovels and backhoes before the walls can be erected (since they’re higher up). This makes building them extremely labor intensive, which increases their price tag by thousands of dollars compared to other options like crawl spaces and slabs—and those aren’t exactly cheap either.

Basement Foundation

To understand the cost of a basement foundation, you must first consider the differences between this type of foundation and other types.

Basement Foundation vs Crawl Space Foundation

The most noticeable difference between a crawl space and basement is the height from ground level. A crawl space is usually located at least 18 inches below grade (the level of your property), while basements are set below that point by about six feet or more. This can affect how much work needs to be done on your home before construction begins—for example, digging out dirt from underneath where pipes may be buried or removing old structures like plumbing lines or stumps that may have been left behind after clearing out trees or shrubs during landscaping projects. A crawl space already has some natural insulation in place because it’s partially underground; however, if you’re building an attached garage then this will also add a layer of surface area where moisture could build up if not properly ventilated as well as provide additional protection against outside elements such as rainwater runoff during storms (it won’t leak into your house). It’s important to understand these differences before deciding which type would work best for getting started on your next project.

Slab Impact On Home Value

If you had to choose, which foundation would you pick?

A slab foundation offers the least expensive and easiest way to build a home. It is also the most common type of foundation in North America because it requires the least amount of excavating and concrete work. However, this type of foundation is often considered unattractive by many homeowners and they tend to take away from their home’s curb appeal. The lack of footings also makes slab foundations less energy efficient than other types of foundations such as crawl spaces or basements.

Cost To Build A Crawl Space Foundation Compared To Other Types Of Foundations

Crawl space foundations are cheaper than basement foundations, but they’re also less durable. Because they aren’t below ground, crawl spaces aren’t as protected from the elements. However, they can still be a good option depending on what you need your house to do and how much money you want to spend.

Crawl spaces are more affordable because they require less concrete than other types of foundations (e.g., slab or basement) since there isn’t any need for support columns or beams that go all the way into the ground; however, slabs and basements offer structural strength and durability that crawl spaces don’t have. A slab foundation is generally better at resisting earthquakes; however, both crawl spaces and basements tend not to do well in areas with high seismic activity like California or Alaska.

DIY Or Hire Poured Concrete Crawl Space Contractor?

If you are thinking about pouring your own crawl space foundation, do not do it. It’s not worth it. You’ll end up spending more than the cost of hiring a contractor and creating a better foundation for your home. The best way to proceed is to hire a professional crawl space foundation contractor who can take care of everything from start to finish.

Here are some things you need to consider:

  • Price – Most contractors will charge by the square foot or cubic yard (not all contractors do this but most do). They may also have different rates depending on what kind of material they use or whether they use their own equipment or yours. Also consider any additional charges such as travel time if they have to come out multiple times before completing work on-site, which can sometimes add up quickly.
  • Contractor History – Do they have references? What kind of work has been done in past projects? Will there be problems down the road with these types of structures due to poor installation practices? A good way around this problem is by using an experienced company that has been around longer than just five years; then again maybe those newer companies know more about how things should be done correctly so maybe go with one instead. Either way make sure whatever decision you make works best for YOU so YOU don’t end up having second thoughts later after making decisions blindly..


Overall, a crawl space foundation is a great option for homeowners looking to save on their home’s overall cost. They are also ideal for anyone living in an area with harsh weather conditions, as they offer more protection than other types of foundations. Once you know how much it will cost to build one on your property, it’s time to decide whether or not this type of foundation makes sense for your needs.
