Find out what is actually wrong with the air in your home. Then fix it once.
We find the cause of mold, musty smells and bad indoor air, tell you plainly what needs to happen and in what order, and make sure the fix holds. It starts with a free 15 minute call with an expert.
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.
Mold inspection and investigation →A big or complicated property
Large homes, estates, several properties, custom builds, a household with health concerns. Keystone puts one expert in charge of the whole problem, from investigation to verified fix.
Keystone →You need a straight answer, now
A lab report you cannot read, a remediation bid that feels high, a house you are about to buy. Talk to an expert today and know your next step before you spend another dollar.
Talk to an expert →Attorney, adjuster, property manager or agent? Independent investigations and written findings for your clients. Work with us →

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.
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.
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 →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.
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.
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.
