5.0 out of 5 stars from 11 Google reviews. Here's what families say after their 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. 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 👍”
Independent inspections, lab-grade testing, and plain-language reports. We don't sell remediation you don't need — and when treatment is required, you decide with the data in hand.
Samples processed by an accredited third-party lab so the report stands on its own — no in-house conflict of interest.
Humidity, moisture content, behavioral contribution — we map why a problem exists, not just whether it's there.
Spore counts, species, comparisons, and recommendations — written so you can act on them without a PhD.
If you don't have a mold problem, we'll tell you. Real homeowners say it best — see our verified Google reviews.
Serving Northern California homes, rentals, and commercial properties alike.
Ascertain if your home or workplace has a mold problem, how bad the problem is, why the problem exists, what its cause(s) are and what can be done. We do this in two ways as part of our mold inspection and testing service.
We have several options when it comes to mold testing. We can discuss which would be most appropriate for your situation if you give us a call or fill out our contact form.
Our expert technicians will use their suite of specialist diagnostic tools along with their expertise to identify problem areas, likely cause(s) and effective solutions.
Expert diagnostics
Our expert technicians use a suite of professional diagnostic tools, combined with their knowledge, to offer insights as unique as the conditions in your home.
The aim of the inspection is to form a picture of why a mold problem exists and, crucially, what can be done about it.
The type of test you need may differ depending on your circumstances and desired outcomes. Call us for clarification — we'll help you pick what fits.
Air samples are analyzed for both alive (viable) and dead (non-viable) mold spores. The lab records spore count per cubic meter alongside the species present.
We capture mold spores in a mold trap. Captured spores are then cultured on a Petri dish. Any living (viable) spores reproduce, and the species are identified and recorded.
Dust and surface samples are collected from suspected areas and analyzed by an independent laboratory for spore count and genus identification.
Data-driven testing
Testing determines whether mold is present, how severe it is (spore count per m³), which mold strains are present, and how those readings compare against contextual baselines.
Results combine into a single report that gives you fact-based insight into the air quality in the home, the cleanliness of its airspaces, and whether any mold remediation is required.
When To Test
Not every situation needs a lab-grade test — sometimes a visual inspection and moisture reading tell us everything we need to know. Other situations benefit from the extra data a test provides:
