“North State Pure Maintenance did a mold inspection for a property I was interested in purchasing. The inspection was very thorough and comprehensive, and included a written report, pictures and lab results. Ron's professionalism and attention to detail was greatly appreciated, and he spent a lot of extra time explaining the results and options to me. I would definitely use them in the future and highly recommend this company to anyone who has a need for the services they provide.”

“I don't know what I would have done without North State Pure Maintenance. Once it was discovered there was a mold issue I called and they called back in less than 5 hours (I called in the middle of the night due to the severity of the mold once it was found) with a time they planned to come and treat entire property in less than 1 day wait time. Immediately the air quality improved and the two technicians that arrived were both friendly, sympathetic towards me in the situation and VERY thorough. They ensured the safety of the home with a follow up call to eradicate any remaining mold spores and left behind filters that would catch any remaining spores from circulating in air Vents. WOW. Above and beyond. Is there a 10 star button on here??!!”
“Ron was really fast and efficient, taking care of the mold after inspection, during my refi, he was able to get rid of the mold in the house in a day or two, then provide documentation verifying there is no more mold in the home and I'm getting ready to close on the refi because he took care of the job that needed to be done by eliminating the mold from my home, which enables me to complete the process and follow through with my refinancing with my lender and close Mold free. Thanks, Ron you get five stars.”

Eureka Services
Our mold remediation services in Eureka.
Mold shows up in different parts of a house for different reasons, so we treat each area on its own terms.
Mold does not show up the same way twice, and where it is growing usually decides how we treat it. Attic Mold Removal deals with roof leaks and vent gaps that trap the coastal marine layer under the roofline, often for months before anyone notices. Basement Mold Removal and Crawl Space Mold Removal cover the below-grade half of an Eureka home, where older wood-frame construction and heavy winter rain keep humidity high most of the year. Bathroom Mold Removal and Shower Mold Removal handle the rooms where daily steam meets tile grout and drywall, a combination that is hard to avoid without strong exhaust ventilation. Wall Mold Remediation and Ceiling Mold Removal reach the mold you cannot always see, since a stain that keeps returning after a coat of paint usually means moisture is still moving behind the surface. HVAC Mold Removal treats ductwork and coils, a common call in older Humboldt County homes where a musty smell only shows up once the heat kicks on. Carpet Mold Removal addresses flooring that has stayed damp long enough for growth to take hold, whether from a slow leak or a closed-off room with poor airflow. Each of these services uses the same patented VaPURE™ vapor and the same accredited third-party lab verification as our whole-home treatment. Tell us where the problem is, and we will scope the right service for it.

The VaPURE™ Process
Four steps. One clear outcome.
Each project follows the same protocol: diagnose, treat, prevent, prove. Here's the high-level view; the detailed walkthrough follows below.
-
01
We find the mold
We inspect your property to find any visible mold growth and the moisture conditions causing it. Air samples are sent to an accredited third-party lab.
-
02
We treat the mold
Our patented VaPURE™ sterilant is applied as a vapor that carries it into most nooks, crannies, and materials in your home, treating mold on surfaces and in the air.
-
03
We inhibit future mold growth
Our antimicrobial protectant bonds to surfaces, helping treated areas resist new mold growth after we leave.
-
04
We prove success with lab tests
Post-treatment air samples go back to the same accredited lab. You get a written before-and-after report, and we don't close the job until the spore counts clear.
Detailed Walkthrough
Whole-home remediation. How it works.
Each project follows the same protocol: diagnose, treat, prevent, prove. We don't improvise, upsell, or spring surprises on you mid-job.
Free · No obligation
01 Property Inspection
We inspect the property to tailor treatment.
Each home is different, and the causes of mold growth could be numerous. Mold can be caused by moisture conditions, structural defects, or a blend of factors. Our specialist technicians help you understand why your home has a mold problem so we can tailor the treatment accordingly.
Our expert technicians use a suite of professional diagnostic and screening tools, combined with their knowledge, to offer insights on the indoor air quality and mold load in your home. We'll use tools on a case-by-case basis ranging from Air-O-Cell tests, Via-Cell tests, moisture readers, and more.
Single-day treatment
02 Mold Treatment
Our patented VaPURE™ process treats mold on contact.
The sterilant is applied as a fine vapor. Its active component is on the EPA's Safer Chemical Ingredients List, and it reaches even the most hard-to-reach areas of the home.
Treatment is delivered in a single visit, typically without demolition and with no relocation required. Most families are back in their home the same evening.
Protective barrier
03 Mold Prevention
The second stage of the VaPURE™ process inhibits the growth of future mold.
We apply an antimicrobial coating that forms a covalent bond with critical surfaces, creating a long-lasting protective layer that doesn't wash off.
The coating electrostatically attracts mold spores, drawing them into contact with the surface. It keeps treated surfaces protected long after we have left.
Third-party verified
04 Accredited Lab Proves Success
Don't just take our word for it.
Verified results, not promises: post-treatment samples go to an independent accredited lab and are compared against your home's original baseline, so you can see the difference the treatment made. We back our work with a workmanship guarantee, so ask about re-treatment options for your property when you book.
Our work is verified by independent scientists working in a third-party, accredited lab. Post-treatment air samples are collected and analyzed against the original baseline, and you get the full report.
The Evidence
Peer-reviewed studies that back each step of the process.
We don't ask you to take our word for it. The VaPURE™ approach is backed by independent research published in indexed journals.

Frequently Asked
Questions about mold remediation.
The time varies based on size and scope, but most homes are treated in a single day.
Costs vary with the unique circumstances in your home that caused mold growth. We tailor our treatment to fit what your home needs. Because VaPURE™ technology is non-invasive, it is often cheaper than traditional mold remediation methods.
No visible residue. The vapor evaporates as it works.
Leave as many personal belongings in the building as possible. Inform your technician of any brass materials inside the home so they can apply the treatment accordingly.
Pets and people need to be out during treatment itself, but the property is safe to return to the same evening: the active ingredient is on the EPA Safer Chemical Ingredients List.
The treatment treats the mold present at the time of treatment, and the antimicrobial protectant continues to work against new spores after we leave. As long as the underlying moisture conditions are resolved, most homes do not need a repeat treatment. We back our work with a workmanship guarantee, so ask about re-treatment options when you book your consultation.
We don't scrape, demolish, and replace: that's the conventional approach. VaPURE™ is a vapor that behaves like a gas, reaching porous materials, wall cavities, and HVAC where mold actually lives. Same outcome, less invasive, lab-verified at the end.
The antimicrobial protectant stage is designed to help treated surfaces resist regrowth, and each treatment is verified by independent lab testing. Because regrowth usually traces back to a moisture source, we also help you identify and address the underlying cause. Ask us about re-treatment options for your property when you book your consultation.
