"They did a great job. They came to fix a leaking toilet bowl and it actually had to be replaced. They picked up the new toilet bowl and supplies and finished the job. Elite was reliable and professional. The cost was reasonable. I am hiring them again to fix the plumbing in my other bathroom."

Excavating questions, answered by experts

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.

It all depends on the scope of the project. A trencher can certainly save time and energy, but you might not need to dig that deep in the first place. Aside from the depth of the trench, the quality of the soil matters. If it’s light, soft soil, you might try a shovel first. However, if the soil is rocky and hard or there are obstructions in it, like tree roots, a machine trencher might be the better option.

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.

Chipmunks dig their burrows about three feet deep and up to 30 feet long. The entrances can be two inches wide or more. Chipmunks are fiercely protective of their burrows and use them to protect the nuts and seeds they gather for the long winters.

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.
