Best Plumbing Excavation in Seattle WA

Wow! This company has blown my mind. We have used them twice in the last year and they have gone above and beyond. Big Bill was our main guy & Dominic was his second. Cannot recommend them more

Frank was professional thorough and quick. I highly recommend Jim Dandy plumbing

Came home to a busted water heater. I couldn't even locate the source of the leak because there was a torrential downpour in my garage. In a panic I called O'neill plumbing and Donna was extremely helpful and calmed me down. I sent her pictures and she was hopeful that the water heater didn't need to be replaced. She was able to confirm that they could send a plumber that night. James and Kyle arrived 3 hrs later and wore masks and shoe coverings. They quickly assessed the problem - my expansion tank failed. They were both nice and courteous while they were in my home and replaced the tank within 30 minutes. I was pleasantly surprised at the cost - less than $400. Such a good experience from start to finish. I highly recommend this company.

I called them late in the evening, they still came out that night and were extremely nice and helpful. Would highly recommend using them for any plumbing job!!!

The reviews about this crew are true, I also had a great experience with Dirt Cheap Sewers for a complete sewer replacement. From Angel initially determining the cause and location of the problem, to offering every option available and on the spot estimating with fair pricing, to delivering on exactly the promise made. Day one, they trenched by hand, in the cramped space under the deck, replaced the root destroyed pipe, and had me back in action by the end of the day. The remaining days also required hand trenching to protect a slope sensitive tree line, and even without requesting it, I watched them take care to not hurt the large primary root structures of the trees, digging under and around them to access the old line, only cutting a few that needed it. This type of care was demonstrated throughout.

Accessing the portion under the house required cutting the slab, and a touch of jack hammering, but before the work began, Austin and Poncho took the time to seal off the rest of the house, as well as some belongings left in the basement. This crew works hard, staying as late as it took each night to finish the days portion of work and get me reconnected, while being receptive to my questions or specific requests. Then, at the end of it all, after back-filling and pouring me a beautiful cement patch, gifting me two new and more convenient clean outs, they literally cleaned my basement better than they found it.

This is a stellar crew, very easy to work with, and I am extremely pleased with the result. I definitely feel like I got my money's worth with these guys.

Amazing drainage repair services! Our storm drain in our driveway was totally clogged and there was no drainage every time it rained. They came out and identified the drainage problem immediately and repaired the drain same day. After hydro jetting they discovered holes in the pipe and more drain clogs. It turned into a two day job because the cast iron pipe was completely impacted and rusted out. They cut the concrete, dug out a new channel and installed about 30 ft of pipe that led to a pop up drain. They also did a great job cleaning up afterwards, which most contractors don’t bother with. Super knowledgeable, professional, affordable and skilled team. Highly recommend and will hire again if needed.

Incredible work from honest businessmen. Was charged 25% of what the other company was offering. On time, communicated easily, and even power washed my driveway for free. Will Call Trenchless any time something goes wrong with my drain

Bryce has reached back out to us, so I will amend my prior review.

Wow, what a quick response from Shane! My client called, frantic, as their shower unit broke right before they were to put their home on market. Shane called immediately and was there early the next morning to fix. They were so impressed!
