"I had a large section of fence that had blown over due to rotting posts. Norberto came out to assess the damage and got back to me the next day with a quote. He was able to man the project the following week and complete the work in 2 days time. Workmanship was excellent and I’m very pleased with the end product. I highly recommend Mount Olive."

"Awesome finish work to our tiny remote cabin! Ryan and crew installed our LVP flooring in just a few hours. He kept us up to date on the project with text and pictures, super helpful since we live in Seattle and had to work. His crew kept the construction site clean and the vendor he used for our cedar interior work was meticulous. Thanks Ryan!"

"We hired Allscapes to do a retain wall on a steep slope in my Redmond house. The job was not an easy one as the slope was steep and along the house. What we really liked - when we had some areas that shall be rethinking and redone, the guys were very attentive, redid everything that we had a concern and finished the job to our satisfaction. We really liked the attitude and customer service. The price was very reasonable when we compared with other contractor. It's been a pleasure to work with the company. I would recommend them to all my friends."

Excavating FAQs, answered by experts

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Excavations take a few days or up to a few weeks. The time it takes to excavate an area depends on the size of the area, the type of soil, the type of excavator, and even the time of year, since winter can make digging up the ground more difficult.

Excavation is priced in cubic yards, so you’ll need to find the volume of the area in order to calculate costs. Multiply the length, width, and proposed depth of your excavation site, then convert it into yards to get the volume. Multiply this figure by the price per cubic yard.

Most homeowners can measure by hand to get a rough estimate, even if it’s tedious. You may want to pull out a tape measure or use a string to help mark the area.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

It can take several weeks for the ground to settle after removing a tree, and the soil under larger, more mature trees can take months. The deeper the tree has been ground under the soil, the longer it will take to settle. However, this extra depth can help you plant new landscaping sooner because you’ll have more space for fresh soil.
