"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!"

"The crew complete work in May 2025. Project complete included building a rock wall, repairing the fence and another rock wall, making a small patio with flagstone, building a raised bed, removing several shrubs and transplanting 2 shrubs and a small tree. The crew picked up the flagstone, and rocks and also compost to use in the garden. In addition, several indoor projects were building a mantel, doors for a small closet and cabinet and dry covers in the laundry room. Norbert was great to work with and Ali for his carpentry skill, as well as the crew. The all worked hard, were efficient and very professional."

"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

Hard soil could be a sign of overly dry dirt, either from poor drainage or drought. It's important to test the nutrient levels, density, and drainage capacity of your soil to see if it's absorbing water properly. Begin by adding a light layer of water and observing how long the soil retains moisture. If you experience a good deal of runoff, you may need to aerate your lawn, apply a wetting agent, or hire a professional for a closer look.

Depth is not a qualifying component of evacuation. Any human-made cut, cavity, or depression in the earth’s surface is considered excavation. The hole from excavation can be any size, shape, or depth. Excavation is used to create foundations, reservoirs, drainage ditches, and roads. Long, narrow excavations are called trenches and are often used for underground utilities.

The digging depth will depend on the size of the trencher you use. Even smaller units can dig up to 4 feet deep, which is plenty for a DIY job. However, much larger trenchers can reach a depth of 18 feet and are better used by a team of pro contractors, not a single DIYer. As with all home improvement projects, use the right tool for the job and proceed with caution.

The average cost of excavation is approximately $3,200, with typical projects ranging from $500 to $15,000. Depending on the contractor, you may be charged between $50 and $200 per cubic yard or an hourly rate of $40 to $180 for an excavation specialist. The total cost is influenced by several factors, including the project size, the amount of soil to be removed, and the soil's condition. Hard soil, tree roots, or excessive rocks and clay can increase the price, potentially adding $200 to $1,200 to the final bill. Other factors that can drive up costs include the presence of nearby structures that complicate the work or tight spaces that require manual excavation instead of heavy machinery.

Errors in site preparation can lead to structural failures or appear costly midway. Professionals ensure detailed, reliable home base development layouts.
