"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

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

Landscape edging is more DIYable than trenching. You can DIY your own digging projects, but proceed carefully and only with proper knowledge of the equipment and appropriate safety measures in place. Keep in mind the project's scope and estimate how long it will take you to do it on your own. While you can certainly save money by DIYing home improvement projects, you can’t exactly hide an unfinished—or worse, ruined— landscaping job from the neighbors. It’s always safer to call an excavation pro near you to get an estimate.

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain.
