Get matched with top excavation pros in Seattle, WA

"Mark was prompt, knowledgeable, and did a great job. I also appreciated the fair price he gave me."

"We had a great experience with Knockout. Small plumbing repair job that they were able to fix quickly. Gave us multiple options on how best to address the immediate problem, as well as prospective problems in the future. No complaints and would definitely hire again."

"Couldn't have gone better. I found Rodrigo on Angi, but then discovered that several of our neighbors had used him and loved him. We were going to get multiple bids but after talking with him, he was so nice, knowledgeable, and reasonably priced that we decided to go ahead on his removing the concrete. We then came up with the idea of using that concrete as a broken concrete entryway path and decided to have him do that as well when our backyard unit was finished. Couldn't have made a better choice. He's creative, conscientious, meticulous, notices things that we hadn't thought of and just a terrific person to work with. Our broken concrete entryway has different colored stones in between and it looks great, a wonderful entrance to the new house. Rodrigo also did a surface for a bike shed we're building and a walkway to and platform for a hot tub. We'd recommend him to anyone."

"Great. It was not an easy job but they went the extra mile to get it done. Thanks."

"ORGINIAL POST: DO NOT USE THIS COMPANY!!! After spending over $2,000 on pumping, inspection and camera work, I had one simple request- WAIT 30 DAYS BEFORE SUBMITTING FINDINGS TO THE COUNTY! We were trying to work the problem. I called TWICE about this and was told both times, no problem, we will wait. They submitted it this morning. Because they did not respect my wishes to wait, I now have to pay over $20,000 through the county when we had a plan in place to avoid that and get it fixed independently. Go with a company that follows instructions, not absolutely ruins your life. Thanks for the 10 year debt I will now have due to your negligence. My realtor and contractor will be referring all other agents and all clients elsewhere, and notifying them all of this unprofessional behavior. EDIT: Here's how I would have expected Serena, the office manager I spoke to today to enter the conversation: yes, you're absolutely right, we did breach agreement, how can we make it right? Here's what happened: per her: "there was a human error that was not our fault. The result would have been the same no matter what" (no it would not have and she has no way of knowing that). "I have you on record asking not to submit it at all" (I told her yes I did say that, then asked what's the extension period, and we're getting off track). "Here's the history of your septic system" again no, we're getting off track. You admitted three times in this conversation you breached our verbal contract. You say the results would have been the same no matter what, but that's absolute garbage- no way she'd know that. If you truly have nothing to hide, and know you messed up (which you admitted to) send me the phone recordings I requested not respond "we will be happy to do that upon getting subpoenaed.""

"They were wonderful to work with. Great communication and great price. I would definitely use them again."

"They are Great People and did everything to help me. I Highly Recommend them to others."

"No none sense! Super skilled! Beyond expectations."

"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!"
