"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!"

"This man did way more than the option I chose. He worked hard and do an amazing job and fixing my home after a tree fell through the roof of one of my bedrooms. I couldn’t have asked for a better job done. I’d hire him again for any other repairs or builds that I may need in the future."

Excavating questions, answered by experts

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

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.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

The time it takes to build a pool—and dig out the area—varies based on the pool size and type. A professional excavator will take between four and eight hours to dig a pool. The process will take longer if they encounter large boulders or tree roots. Keep in mind that this is a small part of the process in the long run. You will need between eight and 12 weeks to build a pool from start to finish, including the time to apply for permits.

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.
