"Josh and Zach are fantastic! They can do anything! Building on heavily treed undeveloped acreage. The built the construction road, dug foundation pits, cleared brush, thinned trees, dug trenches for water lines and electric conduit. They work directly with other contractors and county to get specs, handle inspections, ask questions. Very professional, highest quality work, reasonably priced. I have never worked with a better contractor!"

"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."

"Ron arrived on time and removed the propane tank on my balcony. I was very grateful for the service because the tank was in a grill and the company taking the grill would not take the propane tank. Ron was very personable and efficient. It was great to see the propane tank go."

"Gary and his crew worked very quickly and efficiently on a challenging demolition job that required a great deal of precision. They also did a drain field for my septic system and both projects were completed in 2 days. His crew were hard working, polite and left the job site swept, picked up and very clean. Gary is a pro! No contractor drama. He showed up on time and got right to work. I highly recommend Gaston Brothers Excavating."

"I have had the pleasure of working with the owner of this excavation company on a residential project, and the service was exemplary. He went out of his way to help with the preparation of the house, making sure everything was in order before the continuation of work. Knowledgeable, efficient, and clear, he kept us updated every step of the way. The attention to detail and willingness to accommodate changed everything and were the reason I would highly recommend his services to anyone in need of reliable professional work."

"NestEx provided a quick response for our inquiry for getting our yard graded. He provided a quality job at a reasonable price. I can’t recommend him enough. We are super satisfied with the project and will be using him in the future for any upcoming projects. 11 out of 10."
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.
