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 of the services under mold inspection and testing.
It is one part of the mold inspection & testing work we do across Falls Church, VA.

“Spoke to Bryce. Genuine guy, gives tips even if you don't use their service. Nuff said. He even recommends a competitor if he thinks some services they offer is more appropriate with client's needs. You tell him what you need, he gives you the right answer within his professional/moral view. Rare breed of honest pros. Highly recommended.”
“Bryce has always done an outstanding job for me. Always finds creative solutions to practical problems and gets the job done right the first time.”
“EnviroPure is a fantastic technology employed by fantastic people who value quality work, integrity, and customer health and satisfaction. Our experience with EnviroPure was wonderful. We had a leaking pipe that was hidden behind walls that we discovered when mold started to grow in a visible location but when we investigated the issue we found that the mold spanned 2 levels and several rooms in our home. We did a combination of physical mold removal for step 1 in remediation but knowing that it was already in our air and impossible to truly get it all like that, we followed that up with EnviroPure's services before putting drywall back up and fixing the mess. Bryce was awesome about scheduling and was easy to work with every step of the way. He is a trustworthy resource in a very confusing industry and will not sell you on something that is not a good fit for you. I would recommend this service to anyone who wants to feel better about the air quality in their home, anyone who is renting a home or buying a home that is not brand new... very helpful in so many circumstances. Grateful we found EnviroPure!”
“Bryce was very friendly and took time to explain the process to me. He was responsive to questions and phone calls. Most importantly, he showed up when he said he would and did a great job. Thank you!”
“My wife had the pleasure of working with Mr. Bryce for a remediation project. We had come to know that he is honest with a genuine will to help you and guide you through a hard process such as mold remediation. Glad we got in contact with you Mr Bryce, thank you!”
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.
Each air sample comes from a spore trap that pulls a measured volume of air through a cassette. 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 costs nothing, and on it we'll tell you whether testing is likely to answer your question.
The same accredited lab reads the indoor and outdoor samples, so the comparison is like for like.
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.
The consultation is free, and so is a visual mold inspection. On that call we'll go over what testing your house needs and the earliest visit we can offer.
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.
