"From start to finish super easy to work with. They worked around my schedule and kept me under budget. The crew from A.T.F Construction arrived on time they were knowledgeable and professional. They kept me well informed through the entire process. I can’t thank them enough for saving me money where I didn’t need to spend it. They were honest about products and which ones they recommended. I’m over the top happy with the turn out of the floors and paint. A.T.F construction made my home look like new again. Definitely without hesitation going to use them in the future."

"Mountain top Enterprises got back to me very timely. They were on time, go getters that got the job done. There were some alterations ,upgrades that needed done and they troubleshooted it perfect. They fixed the well leak, added a pressure valve and even helped get my sprinkler system on. Hats off to them. It was a little more expensive than the quote but well worth it."

Excavating FAQs, 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.

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.

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 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.

Generally, a trenchless sewer line is worth the cost. If your old system needs replacement, trenchless sewer repair or replacement can save you thousands on excavation costs. Every homeowner’s situation is different, but this method is definitely worth it in a lot of cases.
