Inspected. Treated. Verified.
As a locally owned, family-run business, North State Pure Maintenance is committed to the health and wellbeing of homes across Northern California. Our patented two-part VaPURE™ process treats mold at the root cause — not just the surface — so you get a verified result.
We don't close a job on a feeling — or a calendar. We close it on a lab result.

“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 two-part VaPURE™ process reaches surfaces, hard-to-reach void spaces, and the air in your home — not just the places you can see. The particles are so fine they bounce off surfaces instead of sticking and creating excess moisture.
In and out in a single day. No relocation, no multi-week disruption.
The active component of our sterilant is on the EPA's Safer Chemical Ingredients List, and breaks down into natural byproducts shortly after treatment: acetic acid (white vinegar), oxygen, and water.
Every treatment is verified by an accredited third-party lab analysis. Ask about our re-treatment terms when we scope your project.
VaPURE™ vapor reaches surfaces, indoor air, wall cavities, and HVAC — the 90% of the home where conventional crews can't go.
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.
From remediation to testing to odor removal — every service is delivered with the same VaPURE™ vapor technology and the same third-party lab accountability.
Our patented two-part VaPURE™ process disperses throughout your home — wall cavities, attic framing, HVAC ducts — and treats mold at the source, not just the spots you can see.

Learn moreOther companies fog with similar chemicals — what's different is how we use them. Our VaPURE™ treatment uses particles so fine they bounce off surfaces instead of sticking and creating moisture, so they stay airborne longer and reach places conventional sprays often miss.
No improvisation. No upsell. Every project begins with an inspection and ends with one — so you know it worked.
A comprehensive, top-to-bottom assessment of attic, living space, crawl space, and HVAC using hygrometers, moisture meters, and infrared cameras — with air, tape, or culturable samples sent to a third-party lab.
When mold is confirmed, timely action matters. We isolate and stop the source of moisture first, and walk you through what caused it and your options going forward.
Our patented VaPURE™ process reaches micro-cracks and crevices throughout your home, treating hidden spores that traditional methods often miss — extensively researched by the Army Corps of Engineers.
Our two-part process leaves an antimicrobial protectant on treated surfaces after we leave, helping resist regrowth when paired with a fix to the underlying moisture source.
“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, and not even a brown spot occurred. The team was polite and professional and I will definitely have this done again.”
Conventional remediation removes what you can see and leaves the rest — the micro-cracks, crevices, and porous materials where mold actually lives.
The active component of our sterilant is on the EPA's Safer Chemical Ingredients List, and breaks down into natural byproducts shortly after treatment: acetic acid (white vinegar), oxygen, and water.
Because the particles don't stick and wet surfaces, they disperse further and treat more of the mold than a conventional spray.
After treatment, a mechanical (not chemical) antimicrobial protectant keeps working against future mold on treated surfaces.
Our patented two-part VaPURE™ process treats your whole property in a single visit. Typically no demolition or relocation needed — and a third-party accredited lab confirms the result before we close the job.
Book Free ConsultationThe VaPURE™ technology North State Pure Maintenance uses isn't just patented — it's been studied. The U.S. Army Corps of Engineers and two independent research teams have evaluated it. Every paper is available below.
Field study · PDF
A six-month evaluation by the Army's Engineer Research and Development Center of the VaPURE™ application system on two occupied buildings at Fort Campbell, Kentucky — measuring both initial efficacy and recurrence.
Lab reports · PDF
A compiled set of GLP-compliant independent laboratory tests of the vapor peracetic acid (VPA) treatment — the underlying chemistry behind the North State Pure Maintenance VaPURE™ process.
White paper · PDF
A technical explainer of the three "magic-bullet" variables — 7.5μm particle size, vapor phase change, and dwell time — that make the treatment behave like a gas and reach where surface cleaning never does.
Authority isn't claimed. It's cited.
Our patented two-part VaPURE™ process is designed to treat mold in your home quickly and thoroughly.
Every inspection and treatment follows NORMI-certified testing and effectiveness standards.
VaPURE™ treatment reaches mold at the source without costly demolition in most cases. The process typically takes just a few hours.
Our patented two-part VaPURE™ process has been studied by the Army Corps of Engineers, and every job is confirmed with before-and-after lab testing.
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.
