If you wish, you can dig a brand new basement. Contractors can excavate your home and pour a new foundation.
This comprehensive guide will help you determine how much money you should budget for the project and what factors to consider when calculating basement excavation costs.
What is Basement Excavation?
Basement excavation is the removal of rocks, dirt and other debris in order to create space for a brand new basement. This is the first step in building construction, where you create a hole to build your new space.
After your house is built, you can excavate a basement. It is a more complicated process that requires excavation contractors with the skills to dig deep into the soil, remove the excavated debris and not damage the foundation. Excavation is usually more cost-effective before construction.
Basement Excavation Cost
Costs for excavation of basements in new construction range between $12,000 and $36,000. This is roughly $10 to 20 per square foot.
The average cost of digging underground beneath an existing house is between $40,000 to $50,000. This comes to about $47-$100 a square foot.
Comparing costs, digging a basement is slightly more expensive than expanding an existing crawl space. A 1,000-square-foot basement will cost between $22,500 to $45,000. Costs for crawl space extensions range from $10,000 to $30,000.
Although crawl space expansion might seem less expensive than digging out a new basement, it is important to factor in the costs associated with construction.
Factors that affect the cost of a basement excavation project
Several factors influence the total cost for a basement excavation. Understanding these factors can help you budget and plan effectively.
Size of Excavation
Large excavations that require local contractors and more equipment will increase the overall cost.
Cost: $75-150 per cubic yard removed of dirt
Raising or Bracing
To avoid structural damage, you need to support your home when excavating the basement. Although hydraulic jacks are faster and more affordable, they can compromise stability. Bracing or underpinning is more time-consuming but preserves structural integrity better than raising.
Cost: Raising (3,100 to 9,400 dollars); underpinning (20 000 dollars).

The Plumbing
When planning your excavation costs, it is important to consider the cost of installing a proper drainage and plumbing system in your basement.
The cost of plumbing varies depending on what fixtures you choose and how they will affect the main sewer. Drainage systems should be designed in a way that keeps the basement dry. This is especially important in areas where there is a high level of water.
Cost: The plumbing expenses for a basement renovation range between $1,000 and $3,000. Drainage systems cost anywhere between $2,000 to $6,000 depending on the local climate, soil condition, and yard grading.
Permits
Building permits are required for all major construction projects, including excavation of basements. The cost of permits depends on the local building codes.
Budgeting between $1,200 and $2,000 is a good estimate.
Foundation
After the excavation and plumbing are complete, a foundation of concrete must be laid. Pouring concrete for the foundation walls, floors and footings is part of this process.
Cost: Prices range from $10,000 to $30,000
Unexpected Repairs
The foundation of a basement may need to be repaired, which can reveal existing problems. Repairs that are not expected can include foundation work, drywall repair, and frame repairs.
The cost of foundation repair can range between $2,100 and $7,800, while other repairs may cost $50 to 80 per square foot.
Can You Dig a Basement Deeper?
It is possible to make a basement deeper if you lower the floor. Basement underpinning allows you to increase the height of your cellar without having to reduce its square footage. It is a great option for people who want to maintain the space they already have.
Bench-footing, on the other hand involves digging out the crawlspace to create a deep basement. However, it can result in a smaller finished basement.
How to turn a crawlspace into a basement
The following steps are involved in converting a crawlspace into a basement:
Scaffolding: Build a structure that will support the weight of your home as you build the new foundation.
Excavate Crawl Space. Excavate beneath the house in order to create a basement, which is usually eight feet deep.
Pour the New Foundation. For the basement, pour four to six feet concrete walls around the house. This will create a solid link between the old and new foundations.
Finish the Basement: Finish the basement and move the house onto the new foundation.
Monitor for Settleling: Keep a close eye on your foundation and basement over a period of 1-2 months to identify any issues.
