What’s the Difference Between Excavated and Unexcavated Crawl Space?


When considering a crawl space for a new home or a remodel, its important to understand the differences between an excavated and an unexcavated crawl space.

In this article, we will look at the pros and cons of both types of crawl spaces, as well as the cost comparison and maintenance requirements.

We will also discuss some considerations to help you decide which type of crawl space is right for your needs.

Read on to learn more about the differences between excavated and unexcavated crawl spaces.

Short Answer

An excavated crawl space is a crawl space that has been dug out further below the surface of the ground.

An unexcavated crawl space is a crawl space that is at the same level as the surface of the ground.

An excavated crawl space has the potential to provide more space for insulation and other components, whereas an unexcavated crawl space is more limited in what can be installed.

Additionally, an excavated crawl space may require additional waterproofing measures to protect the area from water damage.

Definition of an Excavated Crawl Space

An excavated crawl space is an underground chamber that is created by lowering the ground level beneath the houses floor level.

This type of crawl space provides more space than an unexcavated crawl space and can be used to store items, provide access to plumbing and electrical systems, or even be used as a living space.

An excavated crawl space is typically more accessible than an unexcavated crawl space, as it is easier to reach the lower level.

The excavation process for an excavated crawl space involves the use of heavy equipment to dig out an area beneath the floor of the home.

This can be a time-consuming and expensive process, and some homeowners may opt for an unexcavated crawl space instead.

However, the benefits of an excavated crawl space may outweigh the cost, as it can provide additional storage and living space, as well as easier access to plumbing and electrical systems.

Definition of an Unexcavated Crawl Space

An unexcavated crawl space is one in which the ground level is left at its natural level, creating a shallow space beneath the home.

This type of crawl space can be accessed by a door or hatch in the floor, or through a vent in the wall.

Unexcavated crawl spaces are typically not very large, but they can provide additional storage or access to plumbing and electrical systems.

Unexcavated crawl spaces are generally more affordable than excavated crawl spaces, since they do not require any excavation or additional materials.

They also require less maintenance than excavated crawl spaces.

However, they are often more difficult to access, since they are usually located in tight, hard-to-reach places.

Additionally, since they are not as large as excavated crawl spaces, they may not provide as much storage or access to plumbing and electrical systems.

Pros and Cons of an Excavated Crawl Space

When it comes to crawl spaces, an excavated one has a number of benefits.

By lowering the ground level, you create an underground space that can be used for storage or access to plumbing and electrical systems.

This can be particularly beneficial if you need more space for these purposes.

Additionally, because you have lowered the ground level, the crawl space is easier to access.

This makes it easier to access any plumbing or electrical systems that need to be worked on.

It also makes it easier to clean, inspect, and maintain the crawl space.

However, there are a few drawbacks to having an excavated crawl space.

One is the cost.

It can be more expensive to excavate a crawl space than to leave the ground level at its natural level.

Additionally, an excavated crawl space may require more maintenance, as the walls and floor must be waterproofed and insulated.

Finally, if there are any existing underground pipes or utilities in the area, they must be rerouted to make room for the excavation.

Pros and Cons of an Unexcavated Crawl Space

Unexcavated crawl spaces are an attractive option for homeowners who are looking for a more affordable and low-maintenance solution for their crawl space.

The natural floor level of the house is left at its original level, creating a shallow space between the ground and the floor of the house.

One of the main benefits of an unexcavated crawl space is the cost savings.

There is no need to excavate the ground to create an underground space, which can significantly reduce the cost of installation.

Additionally, an unexcavated crawl space requires less maintenance than an excavated crawl space, as there is no need to regularly monitor the ground level or make any changes to the structure.

However, there are some drawbacks to an unexcavated crawl space.

The shallow space means that there is less room for storage or access to plumbing and electrical systems.

This can be a problem if the homeowner is looking for more storage or additional access points to the homes systems.

Additionally, an unexcavated crawl space can be more difficult to access than an excavated one, as the shallow space can be harder to maneuver.

Considerations for Choosing an Excavated or Unexcavated Crawl Space

When considering whether to choose an excavated or unexcavated crawl space, it is important to think about the purpose of the space, the amount of space available, and the cost of installation and maintenance.

For example, an excavated crawl space provides more space and can be easier to access, but it also requires more labor and material costs for excavation and installation.

Unexcavated crawl spaces, on the other hand, are generally more affordable and require less maintenance, but they may not provide the same level of access as an excavated crawl space.

In addition to the cost of installation and maintenance, homeowners should also consider the purpose of the crawl space.

If the space is used for storage, an excavated crawl space may provide more space and easier access.

However, if the crawl space is used for access to plumbing and electrical systems, an unexcavated crawl space may provide more room and easier access.

Finally, homeowners should consider the amount of space available.

An excavated crawl space requires more space for excavation, and an unexcavated crawl space requires less space.

Homeowners should also take into account the size of their home and the area available for excavation or to leave the ground at its natural level.

Choosing between an excavated and unexcavated crawl space is an important decision that requires careful consideration.

Homeowners should consider the purpose of the crawl space, the cost of installation and maintenance, and the amount of space available in order to make the best decision for their home and their needs.

Cost Comparison of Excavated and Unexcavated Crawl Spaces

The cost of having an excavated crawl space installed can vary significantly depending on the size of the space, the type of excavation work that needs to be done, and the materials that are used in the project.

Generally speaking, excavated crawl spaces are more expensive than unexcavated crawl spaces, as the excavation process requires more labor and materials.

Excavated crawl spaces also have the potential to be more expensive to maintain, as they may require more insulation, waterproofing, and ventilation to ensure that the space is properly sealed and that the air quality is not compromised.

Unexcavated crawl spaces are likely to be less expensive to install, as they require less excavation and labor.

Unexcavated crawl spaces can also be easier to maintain, as they generally require less insulation, waterproofing, and ventilation.

The downside to unexcavated crawl spaces is that they tend to be more cramped than excavated crawl spaces, and they may be more difficult to access in order to perform repairs and maintenance.

Its important to consider all of these factors when weighing the costs and benefits of excavated and unexcavated crawl spaces.

Depending on your needs, one type may be a better fit than the other, so its important to do your research and consult with a professional before making a decision.

Maintenance Requirements for Excavated and Unexcavated Crawl Spaces

When it comes to the maintenance requirements for excavated and unexcavated crawl spaces, there are some key differences to be aware of.

In an excavated crawl space, the ground level has been lowered to below the floor level of the house.

This creates an underground space that can be used for storage or access to plumbing and electrical systems.

While this additional space can be beneficial, it also requires more regular maintenance in order to keep the area free of moisture and pests.

This includes regular inspections of the space for signs of water damage, mold, and other potential problems.

Additionally, any plumbing or electrical systems in the space should be regularly serviced to ensure they are in good working order.

In an unexcavated crawl space, the ground level has been left at its natural level, creating a shallow space that can also be used for storage or access to plumbing and electrical systems.

While this type of crawl space does not require as much maintenance as an excavated one, it still needs to be periodically inspected for any potential problems.

Additionally, any plumbing or electrical systems in the space should also be serviced regularly to ensure they are in good working order.

Overall, both types of crawl spaces require some form of regular maintenance and inspection.

However, the type and frequency of maintenance required will depend on the individual needs of the homeowner.

If the homeowner is looking for a more affordable option with less maintenance involved, an unexcavated crawl space may be the best choice.

On the other hand, if the homeowner is looking for more space and easier access to the plumbing and electrical systems, an excavated crawl space may be the better option.

Final Thoughts

Choosing between an excavated or unexcavated crawl space can be a difficult decision, but it doesn’t have to be.

Understanding the pros and cons of each type of crawl space, as well as the cost and maintenance requirements, can help you make the best decision for your home.

Consider your needs and budget to determine which type of crawl space is right for you.
