Here is how much to dig out a basement.

A lot of remodeling goes on with structures.

In homes without a basement, the homeowner may wish to have their crawl space converted or dug into a basement.

Digging out a basement involves a lot of work.

Dig A Basement Deeper: Financial Costs

First, adequate preparations must be to provide reinforcements to load-carrying components.

If you want to have such a procedure performed, one of the primary things to be concerned about is the cost of digging. How much will it cost you to have your basement dug deeper?

This is what we’ll be focusing on.

Here, we’ll be looking at the different aspects of the dig-out basement cost.

Digging an Existing Basement Vs New Construction

Basement excavation falls under one of two categories; digging an existing basement, or performing entirely new construction or dig-up.

For an existing basement, the old concrete floor will have to make a way to dig beneath. The process of digging an existing basement is referred to as underpinning.

Also, additional supports need to be made available for old concrete footings. With the desired depth reached, a new floor and walls are poured.

The process of digging up an existing basement can be done in multiple ways. If you prefer a less invasive approach, then the “benching” method is applied.

New constructions on the other hand are just that; a new basement dug up from scratch. Grading and hauling off of debris and dirt applies to all situations.

In terms of cost, digging up an existing basement might cost less than one being dug from the beginning.

How Much Does It Cost To Dig A Basement?

How much to excavate a basement?

When it comes to digging a basement deeper, you’ll have to consider the cost variations.

These are determined by a lot of factors including the contractor used. Many contractors charge between $40 and $75 per sq. ft. to deepen or excavate your basement.

  • Average Cost Of Digging A Basement

Project costs could range anywhere from $10 to $30. In some cases, you might spend as much as $100,000 or more. It all depends on existing factors that impact prices.

Some of these factors include the size of the basement, as well as the depth of excavation.

On average, you’re likely to incur an excavating cost of around $50 per cubic yard of earth. Now, this cost per cubic yard doesn’t include labor costs.

When added, you’re likely to incur anywhere from $100 to $200 as cumulative costs. The larger and more challenging the project is, the higher the fees will be.

Factors Affecting Basement Excavation Costs

There are cost-determining factors that are central to how much you incur in excavation costs. These include fill removal, provisions for additional support, basement depth, as well as the size of the basement.

Other factors to consider include digging permits, and the method of excavation.

Grading is another possible factor that may determine your eventual digging costs. With these mentioned let’s get into more details about what these factors are and how they impact digging prices.

i. Fill Removal

Any time a basement is being dug, there’s a need to figure out what to do with the fill or earth removed. One of the most common actions taken is having such fill hauled off by dump trucks.

Provisions for the dump truck are mostly included in a contractor’s pricing structure.

Sometimes, homeowners may want to reuse the fill for purpose of grading or simply to fill up another hole or pit around the area. Your particular situation will determine whether or not you get charged fill removal and disposal.

ii. Provisions for Additional Support

When it comes to digging a basement deeper, the extent of work to be done comes under focus. For an existing basement, provisions need to be made for additional support.

This is especially true for underpinning where support is provided for existing concrete footings.

The degree of challenge involved in the dig-up process translates to the cost of the project. The more complex it is to provide additional support, the higher your project costs will likely be.

iii. Basement Depth

Here, we’re looking at excavating your basement a little deeper than it presently is.

As such, it’s important to note that the more the depth, the more costly the excavation project will be. The cost of digging up extra cubic yards of the earth varies from one contractor to the next.

This is mostly due to variations in pricing structures. Every company has its unique pricing structure that’s likely to differ from those of others.

iv. Size of Basement

Size always plays a price-determining role when it comes to digging a basement deeper.

For larger homes, it’s common to see much higher digging prices. Due to the size, grading requires more labor. There’s also the cost of hauling off more fill materials from the digging site.

In a nutshell, the larger your basement is, the higher the cost of digging deeper will be. Having a fair idea of pricing will require calling for estimations.

v. Digging Permits

Digging permits are likely to apply when it comes to digging your basement deeper. Different states have their requirements. As such, you’ll need to find out what applies to your situation.

Doing so goes a long way in helping you budget adequately for the process.

Of course, you’ll need to discuss with your contractor what digging permits are necessary. This is an area in which the contractor is very knowledgeable.

vi. Method of Excavation Used

Basement excavation methods vary.

Two of the most common include underpinning (which tends to be more expensive but worth the investment) and the benching method.

By consulting with your contractor, you get an idea of what benefits and disadvantages apply to both.

More importantly, you get professional recommendations on what best serves your needs and budget.

vii. Grading

After digging a basement deeper, there may be a need to grade the area around. The level or extent of grading mostly translates to cost.

Extensive grading means significant time needs to be spent making the surrounding area suitable enough. This in turn increases the total cost of the project.

The cost of digging a basement deeper has been discussed with lots of possible cost-influencing scenarios looked at. With such knowledge, you’re able to budget adequately for the procedure.

    I would like to get the drainage tubing replaced around the footing of the basement. It’s difficult to find someone to give estimate besides Ayer’s. Can you recommend someone?
