“With the storms this past winter we incurred some water damage to our home and knowing full well that mold grows quickly around here, we wanted to act fast in detecting any issues. We contacted the Mold Marhsal for some testing and luckily, our home doesn't have mold. The peace of mind is worth every penny."

Protecting your home
and health.

Starting with your property's history and floor plan, we assess your ventilation, test moisture levels directly in affected materials, utilize thermal imaging and leverage specialized equipment to dig deep. And because we've developed partnerships with local Seattle area laboratories that provide detailed, honest, and unbiased results, you get a clear picture of what's growing, where it started, and exactly what needs to happen to protect your home and the people in it.

Know Your mold
Our results will uncover the type of mold and spore counts. We'll also compare them against baseline levels so we can determine what's normal, what's not, and if you should do anything about it.
Unbiased Testing
We stand firm in our commitment to unbiased testing. Our pledge is to act as a trusted, transparent, neutral third party dedicated to empowering you with accurate information for informed decisions.
Quick Results
Fast turnaround so you can make decisions, on a home purchase, a remediation bid, or an insurance claim.

upfront Answers,
To Common Questions

What are common signs I should get a mold test?
+
Watery eyes, recurring headaches, or a musty smell are all worth paying attention to. If you're noticing visible discoloration on walls or ceilings, or if someone in your home has been feeling off without a clear reason, it may be worth a test.
Why should I use a testing-only company instead of a remediation company?
+
When a remediation company does your testing, they have a financial stake in what they find. We don't do remediation so we have no incentive to exaggerate findings, recommend unnecessary work, or steer you toward a particular contractor.
What's the difference between a DIY kit and hiring a professional?
+
DIY kits can detect mold, but they rarely tell you what type, how much, or where it's coming from. When we test, we include air and surface sampling, lab analysis with spore counts, and a documented report that identifies the specific mold species and whether levels are elevated beyond normal baseline. The main difference between a DIY and Professional is information, which helps you make the right step forward with a certain level of confidence.
How long does testing take, when will I get my results, and what do they include?
+
Our mold testing service typically takes 60-90 minutes depending on the size of your home. We then take these and process with our lab for analysis. Most results are back within 3-5 days of the test period ending.
How much does mold testing cost?
+
Testing ranges from $200 to $2,500+ depending on the size of your home and the number of samples needed. Most of our clients land somewhere between $500 and $800. The best way to get an accurate estimate is to reach out.
