"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!"

"I recently had the pleasure of working with Rich and his crew, who transformed my outdoor space over the course of two weeks. They created a beautiful patio, fixed my sprinkler system, repaired the edging, and added rock to enhance the landscape. Rich’s attention to detail was evident when he identified that my French drain needed replacement and suggested sealing my back patio. His expertise and proactive approach made a significant difference in the quality and longevity of the work. I highly recommend Rich and his crew for any landscaping needs. Their professionalism, skill, and dedication to their craft are truly commendable."

Excavating questions, answered by experts

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

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.

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.

Directional drilling is complex and requires training to use the advanced machinery. It can be challenging to monitor the position of the drill since there’s no direct line of sight. Directional drilling can also be more expensive with a cost of $10 to $30 per linear foot compared to $5 to $12 per linear foot for trenching.
