Septic Industry Experience in Western Washington Since 2017
Mark joined the family business almost as soon as it launched in 2017. He learned the trade alongside his older brothers, Art Nikolin and Denis Nikolin. On the job, he picked up how drain fields behave, what common pump and float failures look like, and how to read a septic system from what you find at the lid and in the soil around it.
Over time, Mark built up his experience, completed the required Washington State Department of Health coursework, and passed his exams.
"When my brothers brought me into the business, I didn't think twice," Mark says. "First and foremost, I knew my family needed my help and my work. That's how it goes in our family. One starts something, the rest step in and help build it together. The other thing that pulled me into septic work was my love for the nature of our state. I knew that as a septic expert, I could protect the nature of my state and my country."

Mark's Approach: Root-Cause Septic System Diagnostics
Mark's work focuses on finding the root cause, not treating the symptom. One of the most common myths he comes across is the belief that pumping the septic tank solves any septic problem. In reality, the tank's main job is to separate solids, while most of the actual wastewater treatment happens out in the drain field. When a system backs up, the real cause is usually somewhere beyond the tank itself.
Clients respect Mark because he does what his brothers taught him from day one. He keeps the homeowner involved at every step of the job. If the septic is in good shape, he shows the homeowner why. If something is wrong, he walks through each issue with the owner on the spot, so they can see it for themselves. It is not a separate service. It is the way Mark learned the trade in his first years on the job, and it is how he still works today.
"I'm a man of faith, born into a family of faith. Honesty matters a lot to me. That's how my parents raised me," Mark says. "So I always show clients exactly what I find. I always speak honestly about the problems and about the good signs too. I don't know any other way, and I don't want to. God sees everything."

Protecting Western Washington's Natural Environment Through Quality Septic Service
The rivers, forests, and Puget Sound shoreline are what Mark grew up around. Family hikes, fishing trips, woods right outside the window from his earliest memories. When his brothers asked him to join the septic business, Mark wasn't just thinking about the work itself. Septic systems in Western Washington are infrastructure that local rivers, lakes, and bays depend on. A failing septic at one house is not only that homeowner's problem. It is untreated wastewater seeping into the soil, then into the groundwater, then into the streams and bodies of water that everyone shares.
"I was born here. I grew up around this nature," Mark says. "I have three kids of my own, and they're growing up on the same land. I want them to see the same state I saw: the same rivers, the same forests, the same Puget Sound. How carefully I do my work shapes what they and their generation will see of this place. This isn't just a job for me. It's a responsibility to the place where you live and to your own children."

Mark's Educational Mission: Helping Homeowners Understand Their Septic Systems
After years out in the field, Mark realized something. Most of the problems he runs into on service calls could have been prevented. Not because homeowners are careless, but because no one ever explained how their system actually works, which warning signs matter, and which small habits save thousands of dollars in repairs down the road.
That is why Mark decided to step beyond the truck and start sharing what he knows in writing, through articles, case studies, and educational content. He writes for two audiences: the homeowners in the counties he serves, and other professionals in the industry.
The reasoning is simple. If homeowners understand their system the way Mark understands it, they can catch a problem early and save themselves time and money. If other professionals in the trade start recognizing the same patterns Mark sees in the field every week, the overall quality of septic service across the region goes up. And in both cases, the bigger win is the same: less strain on the environment. Less untreated wastewater in the soil, cleaner groundwater, healthier rivers and bays. The same waters Mark grew up around and the same waters his children are growing up around now.
