"Quick response to my request on Friday and demolition the next Monday. The demolition and removal took less than an hour. I am pleased because the dilapidated shed was in the way of my next home improvement project. I told Alan I was leaving for vacation Monday morning. He was on site at 7:15 am."

Excavating questions, answered by experts

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.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

The digging depth will depend on the size of the trencher you use. Even smaller units can dig up to 4 feet deep, which is plenty for a DIY job. However, much larger trenchers can reach a depth of 18 feet and are better used by a team of pro contractors, not a single DIYer. As with all home improvement projects, use the right tool for the job and proceed with caution.

Preparation involves site assessment, clearing debris, grading surfaces, and compacting soil to support stable construction.

Digging a well can cost between $20 and $25,000, depending on your needs. If you’re looking to dig a well yourself, all you need is a shovel. If you’re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total cost of drilling a well will average to $5,500.
