"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."

In addition, he is very patient when it comes to answering questions. We are also very grateful for the fact that he completed the job for us without going one bit over the pre-work estimate. We won't hesitate to use his services again for our next landscaping project."

"Tanner and his crew were professional and thorough. They took care to minimize the impact of having a small loader in my yard, and rehung the gate to the back yard better than it was before. Well done and would recommend."

"Steve was so wonderful to work with. We needed someone to excavate and grade our side yard in preparation for laying gravel. He was very timely in getting us scheduled and his work was very well done. Overall, Steve was a clear communicator, gave a fair price, and took care to ensure we were happy with the results of his work. I would highly recommend him!"

Excavating FAQs, answered by experts

Yes, chipmunk holes may have two or more entrances. Chipmunks can create an entire network of burrows. Having multiple entrances makes it easier for them when trying to escape from a predator, such as a snake, or if an entrance collapses due to flooding. Each entrance leads to the nesting chamber underground, which is where the chipmunk spends the majority of its time sleeping.

The cost to drill a well varies, with a national average of around $5,500 for a 150-foot well. However, prices can fluctuate significantly based on several factors, including your location, the required well depth, geological conditions, local regulations, and the specific drilling methods used. For the most accurate cost assessment, it is best to research and get quotes from local well-drilling professionals in your area.

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.

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.

The best method for digging a trench depends on the scope of the project. For a short, shallow trench (less than 2 feet deep) in light, soft soil, digging by hand may be sufficient. However, digging by hand is labor-intensive, so consider the effort required. A machine trencher is the better option for longer trenches (over 100 feet), deeper ones, or when dealing with difficult soil conditions, such as rocky or hard ground, or obstructions like tree roots. A machine can save significant time and energy in these situations.
