"AP Excavating installed a drinking post for our horses and replaced a water hydrant. Wonderful father and sons family business - great to work with them and their crew. I was impressed with the quality of work and their commitment to making sure they exceeded our expectations. I will be using them for our next projects: entry gate, trenching work and landscaping driveway island. Thank you AP Excavating!"

"Rich Che and the CNS Empire Landscape crew did fabulous improvements on our family home in Wheat Ridge. They corrected drainage on three sides of an addition so water flows away from the house instead of into the crawlspace; replaced 30 feet of exit pipe from the perimeter drain around the foundation of the addition; installed new sod; and removed weeds from landscaped rock areas in the front yard. The improvements look great. Shortly afterwards, I engaged an inspector to check the foundation. The inspector said he visits about 400 houses each year, and this drainage remediation is among the best he’s seen."

"Tanner and his crew were absolutely amazing. Tanner was able to get me an estimate in a timely manner and very reasonably priced. I couldn't believe how nice and fun his crew was they had my driveway installed in no time, actually a day early! I have no doubt its going to last for years to come. I would recommend these guys to anyone who needs an excavator!"

Excavating questions, answered by experts

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help. 

The average cost of excavation is approximately $3,200, with typical projects ranging from $500 to $15,000. Depending on the contractor, you may be charged between $50 and $200 per cubic yard or an hourly rate of $40 to $180 for an excavation specialist. The total cost is influenced by several factors, including the project size, the amount of soil to be removed, and the soil's condition. Hard soil, tree roots, or excessive rocks and clay can increase the price, potentially adding $200 to $1,200 to the final bill. Other factors that can drive up costs include the presence of nearby structures that complicate the work or tight spaces that require manual excavation instead of heavy machinery.

The rules and regulations regarding groundwater use vary between states. To find out if you can dig a well on your property, you’ll have to consult these regulations, address any compliance requirements, and get the appropriate permits. It’s also important to check that your intended location has the right geology and water table to support a well.

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.
