“Ron came and did a very thorough assessment in our house. Before treatment we were constantly coughing and having drainage issues. After the treatment, we’re not coughing and also sleep much better. Thanks to you and your hard working daughter for fixing our mold problem!”

A burst pipe or a roof that gave out during a storm does not wait for business hours, and neither do we. When something like that happens, emergency mold treatment in Eureka, CA usually starts with a phone call the moment you notice the damage, not a scheduled appointment days out.
We are available 24/7, because water damage and mold growth do not stop for the weekend. Ron Mattson and his daughter Zoe run this family business out of Eureka, and an urgent call gets a real person, not a call center reading from a script.

“Ron and his lovely daughter came and cleaned out all the mold in my 3 bedroom 2 bath apartment today. The kindness and the dedication to getting back to me and working with my situation was truly inspiring. North State Pure Maintenance cares! Ron wants you to live in a healthy environment. He was very thorough in telling me exactly what he was going to do. I felt very safe and comfortable leaving my home in his care. It is the first time in years I do not smell mold in my apartment. My son and I are so happy. Thank you North State Pure Maintenance for helping our family be healthy!!”
“It really works! After my kids left the house, I kept our back two bedrooms closed off to save on heating costs. Both rooms are carpeted and after a couple years they took on a very dank smell. After the treatment the smell was completely gone and the air feels clean. I was initially concerned about what the process would do to my house plants (have many) and not even a brown spot occurred. The team was polite and professional and I will definitely have this done again.”
Know What Actually Counts as an Emergency
Not every mold problem is urgent, and it helps to know the difference. An active leak, a flooded crawl space, storm damage that soaked drywall or insulation, a sale closing that has stalled on a mold question, or new tenants moving in on a fixed date all count as situations where waiting makes things worse.
A patch of mold you have been meaning to deal with for a few months is not the same kind of urgent, and that is fine. We treat both, but knowing which one you are dealing with helps us prioritize your call correctly.
Property managers see a version of this too: a tenant reports a leak on a Friday, or an inspection three days before closing flags something nobody caught earlier. Those situations move differently than a routine service call, and telling us the timeline upfront changes how we schedule the crew.
Stop the Water Before You Do Anything Else
If you can shut off the source without putting yourself at risk, whether that is a supply line, a toilet, or a section of roof you can tarp, do that first. Standing water and ongoing moisture are what let mold spread, so cutting off the source matters more than anything else you could do in the first hour.
Do not scrub, spray, or disturb visible growth before we arrive. Disturbing dry mold can release more spores into the air, and it can also compromise how a follow-up lab sample reads. Leave it alone and call.
If it is easy to do, open a window or run a fan to move air through the space. That helps more than any cleaning product will. Move furniture and belongings away from the wet area if you can do it without stepping in standing water, and take a few photos of the damage for your own records before anything gets touched.
Call Us Day or Night
We are available 24/7, and same-week appointments are available for situations that need a fast turnaround. We will not promise you an exact arrival time on the phone, because every property and every road in Humboldt County is a little different, but we will tell you honestly where you fall in the schedule.
Most homes are treated in a single day once we are on-site, using the patented VaPURE™ vapor process that reaches wall cavities, HVAC runs, and porous materials, not just the surfaces you can see.
Expect a Real Assessment, Not a Guess
When we arrive, expect a walk-through of the affected area, a look at the moisture source, and a conversation about what happened and when. If air or surface samples make sense for your situation, we will collect them and send them to an independent, accredited lab.
From there we walk you through the treatment plan before any work starts. Urgent does not mean rushed. It means we move quickly to stop the situation from getting worse while still doing the job right, and we would rather take an extra few minutes to explain the plan than leave you guessing about what happens next.
Get Ahead of a Closing or Move-In Deadline
Real estate closings and lease start dates do not move just because a mold problem showed up at the wrong time. If you are up against a deadline, tell us upfront. We will be direct about whether treatment and lab clearance can realistically happen in the window you have.
Property managers and homeowners in this position usually want two things: a fast, honest answer, and documentation they can hand to the other side of the transaction. We can provide both, and we would rather tell you a deadline is tight than let you find that out on the day of closing.

Frequently Asked
Have questions? Start here.
Have a question we haven't answered? Contact us, or call (707) 879-8928.
We are available 24/7 and offer same-week appointments for urgent situations. We will give you an honest estimate of timing when you call, rather than a promise we cannot keep.
No. Stop the water source if you can do so without putting yourself at risk, but leave the mold itself alone. Disturbing it can spread spores and affect lab sample results.
Often, yes. Tell us your deadline upfront and we will be direct about whether treatment and lab clearance can happen in that window.
Yes. Wind-driven rain, a damaged roof, or a leak that goes unnoticed for a few days can be enough, especially in older Eureka homes with single-pane windows and older roofing that has taken a beating over the years.
Pricing depends on the scope of the damage, not on how urgently you call. We quote after the inspection either way, so an urgent call does not automatically mean an urgent-rate invoice.
