"I needed to stabilize a slope. Norberto presented a plan for a retaining wall and drainage that was both functional and attractive. He provided a detailed bid for labor and materials that was competitive with several other companies He and his crew completed the job efficiently while taking care not to damage existing shrubbery and ornamentals. Norberto is professional and easy to work with. He was very good about coordinating with me. I have and will continue to use his company for other projects."

"I hired Gary Gaston to clear my severely overgrown backyard. He showed up when he said he would to look at the job and give me a bid. I decided to go with Gaston Brothers and we set up a day and time to start the project. Gary said he could do it in one day. Again he showed up on time and started the work. I was impressed at Gary's skill operating the backhoe. That is truly a lost art. He cleared enough to fill 2 full sized dump trucks. Gary went the extra mile by leveling out the yard. It's ready for me to rake it smooth and plant grass. Thank you Gary!"

"All personnel involved were great at their job. From the estimate through the completion, everyone was professional and thorough. What began as removing a concrete drive to allow a plumber access to the sewer main line, became their completing the entire project. This occurred due to the depth of the line. They completed the job quickly, with minimal inconvenience. While they were here, I couldn't have asked for a better experience for a significantly difficult repair."

"Scope of project was removal of existing concrete pavers and hemlock stump, then installing 7-9 rockery flat steps made of natural basalt rockery rocks. We were thoroughly happy with the work from Seattle Rockeries. Harry and his crew were very knowledgeable, fast and friendly. Sharing pics of before and after."

Excavating questions, answered by experts

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.

Landscape edging is more DIYable than trenching. You can DIY your own digging projects, but proceed carefully and only with proper knowledge of the equipment and appropriate safety measures in place. Keep in mind the project's scope and estimate how long it will take you to do it on your own. While you can certainly save money by DIYing home improvement projects, you can’t exactly hide an unfinished—or worse, ruined— landscaping job from the neighbors. It’s always safer to call an excavation pro near you to get an estimate.

A perc test can take anywhere from one to eight hours to complete. The total time depends on factors like the amount of excavation required, the depth and width of the holes, and whether multiple test holes are needed. For a single hole, the process of filling it with water and monitoring the drainage rate usually takes less than an hour. Professionals can often complete the entire test in a single day. While it's possible to get results the same day, some companies may take a few days to provide the official report.

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.

It can take several weeks for the ground to settle after removing a tree, and the soil under larger, more mature trees can take months. The deeper the tree has been ground under the soil, the longer it will take to settle. However, this extra depth can help you plant new landscaping sooner because you’ll have more space for fresh soil.
