independent, unbiased
testing. always.

The Mold Marshal was founded after watching homeowners get caught in a cycle we felt shouldn't exist. You call a mold company, get a cheap test (sometimes free)  and receive a quote for a $8,000 remediation job. It didn't sit right with us because the company handing you test results has a direct financial interest in what those results say. It's not always dishonest, but it's always a conflict of interest and many homeowners feel pressured.

Founded in 2023, our mission is to establish ourselves as the leading indepedent air quality testing experts across Western Washington, from Bellingham to Seattle. By prioritizing our clients' safety we aim to protect our community from hazardous toxins, creating healthier homes and more secure environments.

“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."

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.
