Small particle cleaning: the basics
What is Small particle cleaning (SPC)?
Â
-
It is a deep, professional cleaning method that removes the tiniest invisible particles (mold fragments, biotoxins, allergens, and dust) that normal cleaning and vacuuming leave behind.
-
We use special equipment, HEPA filters, and safe cleaning techniques to drastically reduce the biotoxin burden within the home.
Â
Why do Small Particle Cleaning?
​
-
These tiny particles can stay in your home after historic water damage/mold remediation and continue to make people sick (especially those with sensitive health or CIRS-like symptoms).
-
Regular cleaning does not remove them effectively.
-
SPC helps lower the overall toxin load so your body can heal and you can breathe easier.
​
How is SPC different from normal cleaning?
​
-
Normal cleaning targets visible dirt and debris
-
SPC targets microscopic particles
-
SPC is done in houses that have had previous water damage/mold issues
Â
When is Small Particle Cleaning Recommended?
​
-
After suspected or confirmed water damage, mold and/or bacterial issues
-
Following mold remediation (to remove any remaining microscopic particles)
-
For individuals who are highly sensitive to mold toxins and biotoxins
​
What is the goal of Small Particle Cleaning?
​
To create a cleaner, safer indoor environment so you can feel better and stay healthier long-term.
Our cleaning process
We follow a thorough, health-focused process to remove microscopic mold fragments, biotoxins, and allergens that standard cleaning cannot reach:
​
-
HEPA Vacuuming - High-efficiency particulate air (HEPA) vacuuming of all surfaces, floors, walls, and contents to capture microscopic particles.
-
Health-Friendly Detergent Solutions - Use of non-toxic, no-VOC, detergents specifically chosen for sensitive environments.
-
Disposable Microfiber Cloths - Single-use microfiber cloths ensure no cross-contamination between areas or jobs.
-
Ethanol-Based Cleaning Solutions - Targeted use of high-purity ethanol solutions for effective disinfection and residue-free results on appropriate surfaces.
-
Containment & Environmental Controls - Full containment, negative air pressure, and air scrubbing systems are used when required to protect the rest of the home.
-
Contents & Detail Cleaning - Careful cleaning of furniture, belongings, and hard-to-reach areas using specialized techniques.

Next Steps
1. Book a Consult
Â
Start with a discovery consultation to review your concerns, health sensitivities, previous testing, inspection reports, and project goals. This helps determine whether further assessment, remediation planning, or additional investigation may be appropriate.
2. Schedule an On-Site Assessment
An on-site assessment includes reviewing previous inspection reports and remediation plans, evaluating moisture and building conditions, taking measurements, and determining containment, filtration, access, and project logistics needed for the work.
3. Receive Guidance for Moving Forward
Following the assessment, you will receive detailed guidance outlining findings, recommended next steps, cleaning considerations, project sequencing, and a detailed quote tailored to the scope of work.
