"Nick did a terrific job removing the entire front yard carefully. He shoveled the areas he could not reach with his Bobcat, removed tough roots, kept me informed about potential problems, and spread 8 cubic yards of mulch and gravel efficiently. Isaac (Ike), the owner, was very professional and gave me a good price, and even discounted it when they had to come a day late. The work took three hours and Nick left the front clean and swept. Much appreciated!"

"Giovani and Dell of Ultra Construction were great to work with and they responded quickly and efficiently to our contractor inquiry. They came out the next day and provided a fair and reasonable estimate. Dell and his crew, including Julian came out and had the concrete walkway and stairs installed in just one day. It looks great and we couldn’t be happier with the results. Their prep work and cleanup were outstanding. Would highly recommend this company for any concrete construction work"

Communication was great at front, we discussed any additional services needed in advance and went over the process in general. The excavation, repair, and finishes were very clean. New Era Rooter & Plumbing are very professionals. I will definitely recommend this company and call them again."

"He was available by phone, and was flexible in scheduling meetings which is great. He was professional, and seemed quite knowledgable. In the end, I didn't use Nato's services because his quote was twice as much as the other contractor I was considering. Perhaps his prices may be more competitive in other services he offers. Either way, working with this company was a pleasant experience."

"Miguel completely re-configured our plumbing under the house a few years ago and we have never had issues again. He diagnosed the issue accurately and was able to complete the job quickly and at the highest level of quality. His knowledge of virtually all mechanical and structural aspects of renovation/repair are second to none. I would recommend him without hesitation to anyone and with highest confidence."

Excavating questions, answered by experts

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

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.

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

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.
