"From start to finish, working with Premium Drainage and Erosion Solutions was the absolute best experience I've had with any home project! I met with Adrian, the owner, and he listened to all of my concerns, answered all questions, was so friendly and honest in doing so, and came up with a plan that made the most sense to me compared to other quotes I received. Communication about every aspect of the job - finalizing a plan, scheduling start dates, etc. - was very responsive and clear. As for the work that was done, the Premium D&E crew was absolutely professional, clean and detail-oriented! They went above and beyond what I imagined or thought was possible. They didn't just add the features that were discussed, they totally transformed the space. These guys worked so hard, and you can tell they really love and take pride in what they do. When the project was finished I didn't have enough words to thank them and share my appreciation for all of their hard work!"

"I hired Pro Landscapes to demolish and remove an old shed in my backyard that was rotting and falling apart. Once I contacted them, the owner of the company reached out very quickly and set up an appointment to come and look at the shed. He was friendly and honest, he offered me the cheapest way possible to get the work done, he actually told me the more expensive job I had in mind probably wasn't the way to go, very honest. I am very happy with the work David's company did, they were fast, professional, and kind. And they even hauled away some trash for me that was not in the contract. I'd highly recommend this company for any yard or demolition projects, they will figure out a way to make the price fit the job. Thanks again!"

"ATD did a wonderful job of completely redoing our front yard. The yard is shaded by trees, grass would not grow, and invasive plants had taken over. ATD first met with us to understand what we wanted, and provided a concise but complete proposal. They developed a landscape design which they discussed with us as it evolved. For the installation they first removed the existing plants, grass and weeds and applied an organic weed killer to kill the invasive plants. They installed the new landscaping a few weeks later, and completed it in one day. They applied soil and hardwood mulch, planted a variety of native plants, and installed stone pavers to provide a walkway from our driveway to the house. In addition they installed a dry creek and river rocks to control water runoff. Maintenance, included for next year, includes Spring and Fall cleanups and weeding every 4-6 weeks during the growth season. We are thrilled with the yard, and neighbors have already given complements. The price was good - we did get a quote from another landscaper, and it was significantly higher. We plan to have ATD work on our back yard next Spring."

Excavating questions, answered by experts

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.

Tree experts don’t advise against digging through tree roots, but instead encourage caution and consultation with a local arborist to make sure you don’t damage the tree’s structure or interrupt its water or nutrient intake. An arborist can recommend specific practices when digging and help prune the roots or dig a trench for utilities with a tool that can remove soil without touching the tree’s roots.

In most areas, you will need a permit for excavation work, even for projects that only involve grading or yard leveling. Permit requirements depend on your local government and the scope of the project, but they are especially common for significant digging or work that could affect utilities or public property. These permits help protect the local topography and prevent drainage issues. An experienced excavation company will typically know whether permits are needed and can often handle the process of pulling and closing them for you. You can also verify permit requirements by contacting your local building department and describing your project.

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.
