""ABSOLUTELY SUPERB" - Ken and Rowen were contracted to install Round River Rock Stone along approximately 180 feet (both sides) of my driveway. Ken promptly answered my request for an estimate. The next day he arrived to view the job and was very thorough about understanding my expectations for the project, He offered advice and is very knowledgeable about how to do top quality work. After my reviewing other estimates my decision was to go with McAdams Excavating, Ken and Rowen arrived as promised and quickly began meticulous work. Material was excavated to provided a 3 inch depth of stone, landscape fabric was installed, finally the stone. The duo were meticulous in all facets of this project and it looks absolutely gorgeous! Do not hesitate to hire this company!!!"

Excavating FAQs, answered by experts

Most states do not require excavation companies to hold specific licenses, but many require at least a contractor’s license. Additionally, heavy equipment operators require a special commercial equipment license to operate machinery required for excavation. You can use Angi’s contractor licensing tool to confirm that an excavation company you’re considering hiring is fully licensed. You should also make sure that the excavation team is fully insured before allowing them to work on your property.

Digging out a basement takes anywhere from a few days to a few months. Most projects take at least two to five weeks, but it could take several months if you encounter obstacles. This project takes longer if you need to brace or raise your home before the excavation. Digging out a basement in new construction can take as little as three days.

The average cost for pool excavation is $2,500. This cost can range from $450 to $4,500, depending on the pool shape and size, time of year, and any need to move buried utilities. 

When excavating for your pool, you might have to move existing utilities. You can expect to pay an additional $15 to $25 per linear foot to move gas lines. To move a septic system, it’ll cost an additional $2,000 to $20,000. A pool that is 10 feet by 12 feet averages $450 to excavate, and a 20-foot-by-40-foot pool averages $3,020.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

Dumpsters work best on hard, study, and level surfaces made of asphalt, stone, or concrete. If the surface is uneven or too soft, the dumpster could get stuck or tip over when filled. Keep in mind that you must obtain a dumpster permit to keep it on a city street in many areas.
