It all starts with the test
Meet the InstaScope™: a CAT scan for your whole house
The InstaScope reads the air as we walk through every room, classifying airborne particles more than 160 times per second, so we can see where mold activity is highest. Your results are emailed to you before we leave. The technology traces back to UK defense research into detecting airborne biological threats, adapted for indoor air quality by DetectionTek.
- Every room scanned
- Results emailed on-site
- Pinpoints likely sources, including vents and wall cavities
- Lab species testing available
Room by room
How an InstaScope scan works
- 01
Baseline scan
We measure your air undisturbed to see what your family breathes day to day.
- 02
Source tracking
We walk each room and watch readings live to pinpoint where mold activity spikes, including around vents, under cabinets, and near wall cavities.
- 03
Resuspension scan
We gently disturb carpets, cushions, and soft surfaces and scan again, to see how much is hiding just below the surface.
- 04
Results on the spot
Your results are emailed to you before we leave, and we walk you through them in plain English.
- 05
Next steps
If you need to know the species, we take lab samples where the readings were highest. If treatment is needed, your scan guides exactly where we treat.

What our lab tests for
The species that matter most in Central Valley homes.
Where vs. what
The InstaScope shows where mold activity is concentrated and how much is in your air. It doesn't name species. That's what our accredited lab is for: when your doctor needs specifics, you're buying or selling a home, or you just want to know exactly what you're dealing with, lab samples identify which species are present and how many spores of each.
Lab reports list each species and its count. Results in 24–48 hours.
- Stachybotrys chartarum
The notorious 'black mold' — toxin-producing and tied to indoor water damage.
- Aspergillus
Common in HVAC and damp drywall; multiple species, some allergenic, some toxigenic.
- Penicillium
Fast-spreading on wallpaper, fabrics, and water-damaged materials.
- Cladosporium
Found on painted surfaces, fiberglass air ducts, and damp window frames.
- Chaetomium
A reliable indicator of long-term water intrusion in walls and ceilings.
- Alternaria
A leading allergen — frequent in showers, around windows, and under sinks.
