The Cost Basement Excavation in Olympia, Washington

basement excavation

Basement excavation means digging out a home’s foundation and leaving enough room to create a basement. This service is crucial if you want to add another level or additional space to your house. Basement excavation cost depends on the area you wish to excavate. Most importantly, the professionals need to consider whether there are underlying structures like plumbing systems or electrical lines present or not. They need to plan their excavation to avoid damaging those systems accordingly.

Excavation cost in Olympia, Washington

The basement excavation cost in Olympia, Washington, ranges from $1440 to $5250. There is a difference in price because of the complications involved in the process. A simple and straightforward basement excavation will cost around $1400 to $2550, depending on the area. On the other hand, a more extensive site and complicated excavation process would get costly. The average cost is approximately $3257.

Although most companies charge around $40 to $150 per hour, residential jobs get project bids. Each project bid reflects the amount of dirt removed. For example, one basement excavation company may charge $50 to $200 per cubic yard.

Types of basement excavation

The basement excavation cost also depends on the type of excavation. Here’s a comprehensive guide that will help you negotiate with your service provider better:

1. Basic excavation for new construction

Basic excavation means removing enough earth from the basement to make room for a single-story average home. It requires contractors to dig at least eight feet deep into the ground. The average cost for this type of excavation is approximately $2.75 to $3.50 per square foot. However, excavation costs may go up if the contractors have to work on rocky soil.

2. Additional costs

You may need to pay additional costs for services that don’t necessarily come under regular excavation. For example, most excavation companies will leave the earth on your site. But if you want them to dispose of the earth in a safe place, you may have to pay additional charges—the amount may be $2 per cubic material. You should budget your excavation project by keeping these additional costs in mind. Otherwise, you may need to arrange for transport yourself to get rid of the pile.

3. Preparation work

Sometimes basement excavation requires preparing the work area. But these services don’t come under your excavation cost. For instance, if you want the contractors to provide a satisfactory grading service to prepare the surface, that will later help lay the foundation. You will have to pay at least $1 to $1.5 per square foot more. Stabilization screening may also add another $1.10 to $1.50 per square foot.

4. Excavation in a completed house

If you want to add a basement to your house in Olympia, the excavation cost may range from $12000 to $15000. Again, the total excavated area is crucial to determine the final price. This service is typical for homeowners who want to convert their home’s crawlspace into a basement.
