"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!"

"They installed a new fence and repaired both gates to my existing fence, and weâ re in and out with the job completed in two days. The quality of their work is consistent with the pictures you see. I will be using them on my next project and I will recommend them to anybody who needs a fence. Great communication and an easy to read estimate made things go real smooth during the whole entire process."

"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."

"Jesse is an incredibly hard worker. He removed around 1000sq ft of blackberry bushes, which uncovered lots of junk left over from previous homeowners. He was generous enough to remove the junk along with the bushes, cleaning up our yard to make it safe for the kids to play."

Excavating FAQs, answered by experts

Consultation with the local government helps identify necessary permits, avoid project delays or legal issues, and protect project integrity.

Prior to excavation, you should prepare the dig site and call 311 before you sign anything.

To get your site ready for excavation, you should move anything in the area that isn’t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.

Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.

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.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.
