"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"

"Very quick response and turnaround time. Hired them to clear and grade about 3/4 of an acre on our property. They came to check out my land and gave me a quote next business day. Started the project the next week and finished same day. Professional and kind crew. I'd use them for future 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!"

"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

If you have a broken sprinkler pipe underground, there will be some signs you can easily spot to locate it and take action. These include leaks, water spouts, flooding, consistently damp areas on your lawn, low water pressure, and grass around the sprinkler head that’s taller and darker than anywhere else in the yard. 

If there are no obvious signs of a broken pipe, you can use tools such as water leak mics, leak noise loggers, audio devices that record leaks, and acoustic testing links. 

Broken pipes can lead to uneven watering, plant damage, and higher utility bills. The longer you wait to fix them the more the repair cost may be.

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

Yes, professional installations include trenching or borehole drilling required for ground loops.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.
