Who we help

Three kinds of calls we take every week.

It keeps coming back

You cleaned it, painted it, maybe paid a remediation company, and the smell or the spots are back. That means the moisture source was never found. Finding it is our job.

How it works

One call. A clear plan. A fix that holds.

Talk to an expert

Free, 15 minutes, by phone or video. Tell us what you see, smell and feel, and what has already been done. Send photos or reports if you have them.

Get the right next step

Sometimes that is a dehumidifier and a weekend. Sometimes it is a full on-site investigation. We tell you which, and what it will cost, before anything is booked.

Fix it in the right order

Moisture first, cleanup second, verification last. We make sure the people doing the work are solving the cause, not just the stain.

The part nobody tells you

Most mold comes back because it was fixed in the wrong order.

Mold is the symptom. Moisture is the cause. Keep indoor humidity between 40 and 60 percent and mold struggles to grow; let a surface stay damp and it will return within months, however well it was cleaned.

Stop the air

Close the hidden paths moving humid air inside.

Control the water

Find and cut off every moisture source.

Dry the air

Bring humidity into a safe, stable range.

Fix ventilation

Make the building breathe the way it should.

Clean it once

Remove what is there, the right way.

Verify

Prove it is dry and clean before walls close.

Why people trust the advice

Inspectors first. Nothing to sell you but the truth.

Monitor My Air was built by people who have stood in waterfront estates and in single-wide trailers and found the same problems in both. The air does not care what the house cost. Our investigations draw on the same field discipline taught and practiced by Stanley Yeskolski, President of the Indoor Air Quality Association (IAQA), who consults with us on complex cases.

We do not sell remediation and we take no commissions from the companies that do. When the honest answer is that you do not need to spend money yet, that is the answer you get.

About us →
Established

Damp, moldy homes are linked to asthma, respiratory infection, coughing and wheezing. Estimates summarized by the EPA tie roughly 21 percent of current U.S. asthma cases to home dampness and mold.

Honest

Claims that household mold causes autoimmune disease or "mold illness" are not medically established. We will tell you what is proven, what is not, and what to do either way.

Practical

EPA guidance treats a moldy area under about 10 square feet as something most people can clean themselves. Bigger than that, or coming back, and it is time for a professional.
