We are an alliance of builders, designers, scientists, and remediators raising the standard for what a healthy home looks like in America. Most homes in this country are built on assumptions about water, air, and material that do not hold up over time. We are organizing to change that — in the buildings themselves, in the industry that maintains them, and in the policies that govern both.

They are moisture problems caused by how a building was designed, permitted, and built. Healthier homes already exist. They are not exotic. They are a structural answer to a structural question.
But it cannot fix a building that cannot dry. Treating the wall without treating the assembly produces only temporary relief. The wall is the patient.
Most of the people doing this work are honest people doing their best with the tools available. They deserve a way to be recognized. The homeowners who hire them deserve a way to find them.
The medical questions surrounding mold-related illness are still being studied. We support that research. We do not make claims we cannot stand behind, and we do not need to in order to do this work well.

The home is the patient. The wall is the problem.
From the Founding Charter

Most homes in the United States are built to a code that, in practical terms, makes moisture trouble in concealed cavities a question of when rather than whether. The reasons are technical — vapor management, envelope tightness, ventilation, foundation detailing, mechanical systems — but the result is straightforward. The buildings most people live in are not designed to manage water the way a building needs to manage water.
Around that reality, an industry has grown up to clean up the consequences. In most of the country it is largely unregulated. Only a handful of states require any licensing of mold inspectors or remediators, and the gap has produced a familiar pattern: free inspections that always seem to find a problem, marketing built on fear, encapsulation passed off as remediation, clearance testing performed by the same company that did the work. People who came in worried about their home leave more worried, with a bigger bill and no clear sense of whether they were helped.
None of this is a verdict on the trade as a whole. Most of the professionals in this industry are honest people doing real work. But the structure they operate inside makes it hard for homeowners to tell the careful from the careless, and hard for the careful to be paid like the careful. The Alliance exists for that majority — to give them a public standard, a public roster, and a coordinated voice on the upstream changes the situation actually requires.
Every member of the Alliance signs the Founding Charter. It defines, in plain language, what professionals in this field will and will not do — separation of testing from remediation, root-cause documentation, no fear-based marketing, no encapsulation as cleanup, independent verification.
Members in good standing are listed publicly. Members who fail to live up to the Charter are removed publicly. Membership is a current claim about how a professional operates, not a tenure.
State licensing of mold professionals. Code reforms that fix the structural failures we see daily. Mandatory disclosure of prior water damage. Protections against the non-disclosure agreements that silence affected occupants. These are the levers that actually move the situation.
Building science research. Independent medical research on environmentally-acquired illness. Advocacy organizations like Change the Air Foundation. Hypersensitive-occupant medical communities. The structural answer requires the scientific work to keep moving.
The firm that finds the problem is not the firm that profits from fixing it. We do not grade our own homework.
Every assessment we do identifies why the contamination occurred — not just that it did. A report without a cause is an incomplete report.
No “toxic black mold” framing. No same-day pressure. No manufactured urgency. We will tell you what we found, in plain language, and let you decide.
Encapsulation is not remediation. Sealing in a problem is not solving it, and we will not represent it as such.
If we have a financial relationship with a product, a referred firm, or a downstream contractor, we put it in writing.
Membership is not tenure. It is a current claim. If we cannot keep these commitments, we should not be on the roster, and we won't be.
Most of this industry is focused on the problem. We are here to guide them to a solution.
