Conventional mold cleaning removes what you can see and leaves the rest. North State Pure Maintenance's patented VaPURE™ vapor treats mold on surfaces and throughout the air in your home — then an accredited third-party lab confirms the result before we close the job.

“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. The team was polite and professional and I will definitely have this done again.”
“They did a wonderful job! Treated my home like it was their own. My house was full of mold it’s all gone now — I am forever grateful. Super nice crew, family run business. Recommend them to anyone with a mold problem.”
“We got our house done and all I can say is that this really works, not only organic, but no chemical smell not stains especially with the weather we get here, haven’t seen a spot of mold since. Thank u for ur work.”
“We got our house done a couple weeks ago, and when tell you there is no more musky smell when we get home from work. This WORKS!! Thank you so much!!”
“Ron was more than thorough in his inspection & gave us a quote that was adequate for the scope of work. So glad we went with his company vs the others.”
“Quality work. My home is a much better place now. The owner is very easy to work with. I would absolutely recommend this company. Two thumbs up 👍”
Our patented VaPURE™ system treats surfaces, hard-to-reach void spaces, and the air in your home — not just the places you can see. Air-quality results are confirmed by lab testing before we close the job.
In and out in a single day. No relocation, no multi-week disruption.
The active component of the sterilant is on the EPA's Safer Chemical Ingredients List. It breaks down into natural byproducts shortly after treatment: acetic acid (white vinegar), oxygen, and water. Most families return home the same evening.
Every treatment is verified by an accredited third-party lab analysis. Ask us about re-treatment options for your property when you book your free consultation.
VaPURE™ vapor reaches surfaces, indoor air, wall cavities, and HVAC — far more of the home than conventional crews can reach.
Vapor reaches what scrub-and-cut crews need to break walls to find. Less mess, less rebuild, less cost.
We test the air before and after. You get the lab result on paper.
North State Pure Maintenance is licensed to use Pure Maintenance's patented VaPURE™ vapor treatment — the same technology studied by the U.S. Army Corps of Engineers. It treats mold on surfaces and in the air, penetrating wall cavities, HVAC, and porous materials at the spore level — using an active ingredient on the EPA's Safer Chemical Ingredients List.
VaPURE™ wins where it matters most: lab-verified results, whole-home reach, and a treatment that leaves your home (and your belongings) where you left them. Here's how it compares against the alternatives.
We treat single-family homes, multi-unit residential buildings, and commercial properties across Northern California. The same patented VaPURE™ vapor, the same accredited third-party lab verification, scaled to your site.
Book Free ConsultationEvery project follows the same protocol — diagnose, treat, prevent, prove. Here's the high-level view; the detailed walkthrough follows below.
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.
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.
Our antimicrobial protectant bonds to surfaces, electrostatically attracting spores and mechanically neutralizing them on contact.
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.
Every project follows the same protocol — diagnose, treat, prevent, prove. No improvisation, no upsells, no surprises.
Free · No obligation
Every 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
The treatment applies a fine vapor of the sterilant — its active component is on the EPA's Safer Chemical Ingredients List — which treats mold through cell wall erosion and protein denaturation. Our proprietary technology provides thorough coverage, reaching even the most hard-to-reach areas.
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
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 and other microbes, drawing them into contact with the surface and mechanically neutralizing them — keeping your home protected long after we've left.
Third-party verified
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.
We don't ask you to take our word for it. The VaPURE™ approach is backed by independent research published in indexed journals.

The time varies based on size and scope. Typical home treatments can be completed in 4 to 6 hours.
Costs vary with the unique circumstances in your home that caused mold growth. We tailor our treatment to ensure the best results. 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, the treatment should not need to be repeated. We re-treat at no cost if a follow-up lab test shows it didn't take.
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 every 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.
The first step is a free telephone consultation with a specialist. It helps you understand why you have mold, the causes, and what can be done about it — including North State Pure Maintenance services, availability, and pricing.
A small, senior team — so we treat each home like the only one we're working on this week. Currently accepting new clients across Northern California.
