"We were very impressed with the paver work the Accurate Grading team did for our driveway and sidewalk to our house. Cameron did a thorough walk-through with us and provided a very reasonable quote, compared with others. They got our project going within a week, and showed up on time daily. The crew paid great attention to detail and kept us up to date and confirmed decisions on design along the way. They did an excellent job grading and prepping the driveway after finding several large boulders. Can't recommend enough - great value and enjoyable experience!"

"Very respectful and friendly. Needed to have a site cleared for construction and they were able to accommodate my needs as I lived on the property at the time of clearing and grading. I was more than satisfied with the results and time it took for them to complete the job."

"Had 2 properties that needed upgrades on backflow valves to meet new requirements. Major excavation, removal of old valves, installation of new valves and concrete replacement. CRM crews were punctual, professional and knowledgeable of permitting procedures and inspections. Great to work with, on budget and willing to work with us on schedule since our business is 7/24/365."

"This is the second time I've used Silverback and I'm about to call for a third job. They're fantastic! I had an old shed filled with pesticides and rat poop that I wanted gone. Without me even having to be there, Chris came out, took a look and then called me with an estimate of $450.00. I came home later that day and that longstanding eyesore was gone, the rat pooped cleaned up and the pesticides stored in a box and left for me to dispose of at the next neighborhood hazardous waste drop off day. Another great experience."

"When we purchased the house, it was a 30 year old home. Almost everybody in the period of five years to seven years wanted to convert to copper plumbing. So what they offered at that time was anyone you referred to if they chose to use their service, you have $500 cash payment which was really nice because half of our neighbors and our family members used them. I do not know what they do now, but it is a really nice service because they are a very good company. They did a great job."

Excavating questions, answered by experts

Yes, you can install a trench drain if you already have concrete in your yard or garden. While it can complicate some aspects of the job and slightly run up the cost, it is doable. Residential trench drains can be easily retrofitted to outdoor areas with concrete without having to remove excessive amounts of your patio, pool area, or decorative walkways.

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.

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. 

The easier way to find buried sprinkler lines is to use the plan from the professionals who installed the system. If you don’t have professional plans, listen for running water on your lawn when you turn on the system. You may also spot wet areas, giving you an idea of where the heads are. Once you find the sprinkler heads, you’ll likely be able to connect the dots between them, revealing the system below.

Trenchers can dig holes as narrow as 4 inches or as wide as 4 feet. Check the specifications of the trencher you rent or buy to determine how wide it will cut into the landscape. Better yet, let the excavation company know how wide you’d like the trench to be, and they can help you choose the right trencher for the job (or do it for you).
