Buyers and sellers can read the same lab numbers before closing.
We do mold testing in Falls Church for buyers and sellers who want lab numbers on paper before a closing. Two weeks before settlement, the buyers notice a musty smell in the basement and ask for a test, and the sellers want an answer they can hand over.
A test puts the same numbers in front of both sides. We take air samples, tape samples or both, depending on the question, and send them to the lab.

“Life-Changing for My Family's Health! As a certified health coach, a wife, and a mom to two girls aged 7 and 12, my family’s health is everything to me. Discovering we had mold in our home—and that it was causing our fatigue, anxiety, depression, and allergies—was nothing short of horrifying. We immediately removed the source. After careful research, we invested in dry fogging. The entire remediation process was incredibly easy! The best part was we had our house retested and no mold showed up! :) It works! Once that physical stressor was gone, our symptoms drastically improved. The allergies, fatigue, and anxiety lifted. Every penny invested was worth it. While we still make an effort daily to maintain optimal health and ensure our house stays mold-free, the heavy burden of worry is gone. Best of all, we now know exactly what to do if we ever face this situation again. Being able to lay my head down at night knowing my family is safe is truly priceless. I cannot recommend this service enough! Liz Lowe Dry Fog Client”
“Outstanding service and expertise...offers great comfort to homeowner wanting to address potential health concerns.”
“We've had water damage and mold in our basement in the past that was remediated. This summer we started to smell an odor than concerned us that it might be returning. A trusted friend recommended EnviroPure so we called Ron Payne. He came out the very next day! He was respectful, thoughtful, a good listener, and knowledgeable. He checked our areas of concern; scheduling was seamless and the price reasonable. A few days later, Jake from the company came out to treat our home. When we returned home the next day, everything smelled fresh and clean, not overpowering. The company followed up respectfully and timely. Thank you, EnviroPure, for servicing our home!”
“Can’t recommend them enough! Ron came out to evaluate the items we were worried about and was able to work with us on what we specifically needed. Service was fast and efficient.”
“Ron was great! He didn't make me feel like he was trying to “sell” me and even gave me an option for a quick fix while I think of the big picture of doing my entire home.”
The form that goes with Virginia's Residential Property Disclosure Act tells buyers to do their own due diligence. Among the checks it lists are a home inspection, a mold assessment and a residential energy analysis, and the mold language is the same in the version that takes effect on 1 January 2027.
Whether a particular test meets what a buyer or their agent has in mind is for them to judge. What we provide is a lab test of the air or of a surface, with the results in writing.
Either side can. Sellers sometimes test before listing and hand the report to buyers with the disclosures. Buyers test during their due-diligence period, often after a musty smell or a stain turns up on a showing.
A seller's test before listing also shows whether there is anything to deal with while there is still time, before a buyer's inspection deadline is running.
When both sides want numbers, one test with the report shared saves a second visit. Contract deadlines, contingencies and who pays are for your agent; we don't advise on them.
The Census Bureau's survey puts the median value of owner-occupied homes in ZIP 22043 about a fifth above the Fairfax County median, and McLean's at nearly double the county figure. On a purchase that size, the lab's few business days are worth planning for.
Book the test early in the due-diligence window, so the results arrive with time left to act on them.
High indoor counts mean the next job is finding the moisture that feeds the mold, then agreeing with the other side who handles the work and when.
If treatment goes ahead, post-treatment samples go to the same lab. Keep the before and after reports together with the closing papers, so the next owner can see what was found and what changed.
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.

One report can serve both sides. It belongs to whoever ordered it, and they can share it with the other party and the agents.
No. A test adds the genus and the spore count in the air, which helps when a sale needs proof on paper.
A tape lift suits a stain someone wants identified. Air samples suit a smell, or a worry with nothing to sample. When a buyer has flagged both a stain and a smell, we can take both.
Vacant and staged houses can both be tested. Tell us if the HVAC has been off or the house has been closed up for weeks, because stale, humid air changes what the samples show, and we note it on the report.
Tell us when settlement is. Call us and we'll talk through next steps and the earliest visit we can offer.
