Our Standard of Care
Most companies scrub the surface mold and tell you it's gone. We address the root cause, not just the visible effects — identifying what's feeding the mold, treating it with our VaPURE process, and confirming the result with before-and-after testing.

We don't close a job on a feeling. We close it on a completed inspection.

“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.”

Healthier Homes

Whole-home mold specialists.

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.

One-day treatment

Most homes take just a few hours, not days — no hiring extra contractors or extensive renovations.

EPA-listed sterilant

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.

Re-treatment terms available

Ask about our re-treatment terms when we scope your project, plus optional recurring Peace of Mind inspections.

Whole-home, not just the visible mold

VaPURE treatment reaches micro-cracks and crevices throughout your home — areas traditional methods often miss.

Typically no demolition

VaPURE treatment reaches what scrub-and-cut crews need to break walls to find. Less mess, less rebuild, less cost.

Before & after testing

Comprehensive inspections from start to finish to confirm the treatment actually worked.

Inside Our VaPURE Process

Break the cycle of mold.

Other 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.

  • Particles about half the size of a mold spore — sized to reach where mold spores travel
  • At least one-tenth the size of a conventional fogging droplet
  • The active component of our sterilant is on the EPA's Safer Chemical Ingredients List
  • Formulated to leave no residue on electronics and home furnishings — most homes are ready for re-entry the same day

Our Protocol

The North State Pure Maintenance process.

No improvisation. No upsell. Every project begins with an inspection and ends with one — so you know it worked.

01

We identify the cause

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.

02

We address the cause

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.

03

We target existing mold with VaPURE treatment

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.

04

We help prevent future growth

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.

The Science

Patented VaPURE technology reaches what cleaning often can't.

Conventional remediation removes what you can see and leaves the rest — the micro-cracks, crevices, and porous materials where mold actually lives.

    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.
