"Randy and team did an excellent job on our walkway. They were prompt, stayed in close communication, and were ready to go when the weather allowed. Our walkway looks fantastic and is safe which was our primary concern. We couldn't be happier and would highly recommend!"

"Totally professional, cordial, & detail oriented. Many thanks to Paul and Ron for doing such a fantastic job! Our large fuel tank had shifted underground, but they handled the unusual situation well. Dig site looks perfect, as though untouched. Too bad we only had 1 fuel tank, because I'd gladly hire them again.Paul even arranged to have our oil burner picked up by someone that may be able to reuse it. Thank you!"

"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!"

FAQs for excavation projects in Sammamish, 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.
