"Leonard expertly repaired my slate walks and patio that had lifted and settled over time. The process included power washing the stones, laying and leveling fresh stone dust, then replacing the stone -- including replacing those that had broken. The pricing was fair and the work outstanding. I will use Leonard again and recommend him to friends and neighbors."

"Andi is the only mason who will ever work on my house. My house is the gray cape in several photos of his websites . He tackled a very steep incline and built magnificent tiered walls, blue stone steps and walkways, and the patio around my pool. He has also built retaining walls, several walk ways and patios for my home. He recently put up stone veneer on my chimney. Andi is a friend, and truly a man of his word. Andi has vision and he always makes time to talk with you about not just what you want, but what you may need, without ever going over the desired budget. If you want quality work, done on time and on budget he is your guy. His crew is as respectful as he is and I cannot express how happy I found him."

Excavating FAQs, 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.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help. 

Yes, an excavation company is the best option for land grading and yard leveling. General landscapers might be able to tackle these projects, but an excavation company will do a better job because they’re used to operating the necessary heavy machinery. Landscapers might opt to do the work manually, which takes much longer and could cost you more in labor fees. Finally, excavation companies will understand local regulations and know when you need permits to legalize the work, while a landscaper might not.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

Excavations take a few days or up to a few weeks. The time it takes to excavate an area depends on the size of the area, the type of soil, the type of excavator, and even the time of year, since winter can make digging up the ground more difficult.
