"They came to look at some work on a Saturday and just did it rite then. I wasn't expecting that so was thrilled. Did a great job on a totally miserable project, got it done quickly, cleaned up and cost was very fair. I'd recommend them in a heartbeat"

"Loved there fnshed work. Had fifteen yards of concrete patio and a block wall bulit. They not only did great job but they spent the time doing it right. Not one crack in the concrete. They took care of dranige issues I did not even think of. Had a buddy go with a diffrent compney at the same time and his 10 yard patio is all cracked up. If you want it done right then go with Universal Landscaping."

"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."

"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!"

"Arcadian designs installed a paver patio and low retaining wall in the side yard of our home. They were very communicative, helpful when answering my questions and professional. They went above and beyond to ensure the design of the patio was functional and beautiful. The work was completed on schedule and with great attention to detail, plus a 5 year warranty that other bidders didn’t offer. I would highly recommend Arcadian for hardscape work!"

"They quickly assessed the situation, gave a reasonable quote, and were very proficient and professional. My condo unit was under contract and a water leak caused by another unit needed to be repaired asap and they did it. Also kept me well informed."

FAQs for excavation projects in Bellevue, WA

Depth depends on the type of installation and the regulations in your area. Water supply lines typically require 24 inches, while drainage pipes are often installed 36 inches below grade. For most general projects, a depth of 12 to 24 inches and a width of about eight inches is sufficient. Sticking to these specs keeps your utilities safe, code-compliant, and easier to maintain later.

When you need to run utilities underground, you’ve got two main options: boring or trenching. Boring employs directional drilling to install utilities without exposing a continuous channel, while trenching requires excavating an open channel to place utilities securely. Directional drilling preserves landscape integrity, whereas trenching provides direct access for installation, albeit with greater surface disruption. This clear comparison helps you select the method best suited to your project.

Plan on 12 hours to dig 100 linear feet when the soil is cooperative and you can work continuously. This timeframe applies when work is performed consistently and methodically. Factors such as rocky soil, tree roots, obstructions, and frozen ground increase the overall duration, demanding extra planning and effort. Comprehensive operational planning ensures that every challenge is managed efficiently and the project is completed on schedule.

If you want your yard to look untouched, laying fresh sod over the trench is the quickest fix. New sod needs 30 to 45 days to root and blend with the rest of your lawn. A local sod pro can provide you with a firm timeline and tips to ensure the grass takes hold and maintains your curb appeal.
