We measure the humidity first, because a damp room tells us where the air samples should go.
Our air quality testing in Falls Church measures indoor humidity before it samples the air for mold spores. Typical July dew points at Dulles sit in the mid-60s °F (NOAA hourly normals), and air that humid makes the Virginia Department of Health's suggested indoor range of 30 to 60 percent hard to hold without air conditioning or a dehumidifier.
Testing suits a problem you can smell or feel but can't point to: a musty room with nothing visible, a leak that was dried out with doubts about whether it dried in time, or a room that stays damp with the dehumidifier running.
It is one part of the mold inspection & testing work we do across Falls Church, VA.

“Ron and his son did a fantastic job, working around schedules and price was unbeatable value. Thank YOU.”
“Working with Enviropure was a great experience. Ron explained the mold removal process in detail. Jake arrived at the appointed time and the house felt refreshed and clean after the service. I would highly recommend this company.”
“After discovering I had mold throughout my house I contacted EnviroPure. Prior to the treatment Ronald Payne (owner) came to my home & thoroughly explained the entire process of the mold removal dry fog vapor treatment. He was professional & personable. I chose EnviroPure over several other companies. Ronald & Jake Payne did a thorough job removing the mold from my home. I left home for 6 hours as requested & upon my return I could tell that the air was cleaner & fresher with a slight vinegar aroma which dissipated. I just referred a family member & a friend for their services.”
“Absolutely phenomenal company. They took amazing care of our house finding the issue and resolving it. They communicated well with everything that was going on, and their pricing was very reasonable. Hopefully we don’t have to deal with mold again, but if we do we’ll be calling Ron again!”
“We experienced minor water damage from a small leak, but unfortunately, our insurance declined coverage. Several large remediation companies provided quotes that seemed excessive given the scale of the issue. Based on our realtor’s recommendation, we reached out to EnviroPure, and we’re glad we did. Ron appears to be very knowledgeable and answered all our questions and addressed any concerns we had. He is responsive, and completed the work exactly as discussed. So far, everything looks great, and the solution appears to be both cost-effective and appropriate for the scope of the problem. I plan to update this review in a year, but for now, I’m very satisfied with the results and appreciate the savings and straightforward approach.”
We take relative humidity readings room by room, including the basement and any crawl space, and moisture readings in walls, floors and framing wherever something looks or smells wrong. A room reading above 60 percent is where the air samples go first.
A hygrometer from a hardware store shows where a room sits from day to day. Leave one in the room that worries you for a week before we come, and tell us the highest reading you saw.
By our calculation from NOAA's hourly normals at Dulles, dew points average in the low 60s °F in June, the mid-60s in July and August, and the low 20s in January. A house that reads dry in January can read very differently in August, so we note the date and the weather beside each reading.
If the smell comes with humid weather, test in summer, because testing in January can miss an August problem.
Spores drift in from outside all the time, so we take an outdoor sample on the same visit, as close in time to the indoor ones as we can.
For the most useful indoor sample, keep the windows closed, run the HVAC as you normally would and skip vacuuming and dusting the day before.
The numbers mean most side by side. Indoor counts close to the outdoor sample, with a similar mix of genera, describe a house breathing ordinary outdoor air. Indoor counts well above the outdoor sample, or a genus indoors that barely shows outside, point to something growing inside, and the humidity readings usually show which room to look in.
A single high room in an otherwise ordinary house narrows the search to that room and the ones around it, which is where we take a closer look at walls, floors and any ductwork.
Our testing looks for mold spores and the moisture behind them. Radon, carbon monoxide and chemical pollutants such as VOCs need a different specialist, and if that is what your question really is, we'll say so on the first call.
Samples go to an accredited third-party lab with no affiliation to EnviroPure. Air and tape results usually come back in 2 to 3 business days.
The report gives the spore count per cubic meter and the genus of what was found, compared against outdoor and baseline samples. It is written in plain language with clear next steps, and it is yours to keep.
The consultation and visual inspection are free, and when the inspection confirms visible mold, you get an estimate. On the call we'll also tell you whether testing is likely to answer your question.
EnviroPure is a licensed provider of Pure Maintenance's patented VaPURE process.
The mold inspection & testing page walks through the whole process, start to finish.
That is one of the most useful times to test. Moisture readings show whether materials are still wet, and air samples show whether indoor spore levels sit above the outdoor sample.
It can lower the indoor count for a while without touching the source. Tell us if one has been running, and where, so we can note it beside the sample from that room.
Then the air itself looked ordinary on the day. A smell with ordinary numbers can come from a damp material that isn't releasing many spores, so the moisture readings in that room decide where we look next.
If we confirm visible mold, you get an estimate. If the concern is the air rather than a visible patch, we'll talk through testing.
