Dedicated to Healthier Homes and offices, and Healthier lives

What makes us different?

Client-Centered Approach
We take the time to listen, understand your symptoms, and tailor our assessments to your unique situation.

Advanced Diagnostic Tools
From moisture mapping to spore trap analysis, ERMI testing, VOC screening, and more — we use validated methods to deliver accurate results.

Clear, Actionable Guidance
We don’t just hand you a report; we explain what it means, the potential health implications, and the next steps for remediation or prevention.

Ethical, Independent Testing
We do not perform remediation, ensuring our assessments stay objective and trustworthy.

Our Commitment

We believe that everyone deserves a home that supports their well-being. Our role is to empower you with knowledge, data, and confidence so you can make informed decisions about your environment.

Why Test Independently?

When a mold remediation company comes to your home to inspect, they are invested in finding mold and selling you their remediation services. Our company performs thorough, professional mold inspection and testing services only. This way, YOUR best interest remains our top priority. If we find no sources of significant or dangerous mold growth after our inspection and testing are complete, we will recommend that no remediation is necessary. If we do find areas that need to be addressed with remediation, we can provide a written report with recommendations and protocols required to resolve your issue, nothing more.

Secondly, if you have already had remediation work done on your home, how do you know if the problem is actually resolved? Many sources of water intrusion and mold lie hidden behind walls, in ventilation systems, attics, under carpets, etc. It is crucial to have independent mold testing done post-remediation to ensure that your remediator a) used proper containment, not cross-contaminating your entire home, making the situation worse than before, and b) did a thorough and complete job removing the source of the problem. This documentation can be precious if you work with your home insurance company.

Our licensed professional team aims to provide our clients with the most accurate and unbiased information possible. Your health and safety will always be our priority, guaranteed.
