A finished Potomac basement had water-damaged ceiling drywall with visible growth, mold creeping along the wall bases of closets and corners, dark spotting on the joists and subfloor above, and ductwork that had been pulling air through it all. Here is how Mold Pro Solutions handled a Condition 3 basement: full pack-out, negative-air containment with a decontamination chamber, partial ceiling and lower-wall removal, framing cleaning and encapsulation, and HVAC duct cleaning.
A homeowner in Potomac, MD called Mold Pro Solutions after finding mold on a water-damaged section of the basement ceiling and dark growth creeping up from the floor line inside two storage closets. Our guide to the signs of mold in a house covers both patterns: staining that spreads from a ceiling leak, and growth that starts low on a wall where moisture collects.
The inspection classified the basement as Condition 3 under the IICRC S520 standard — actual microbial growth on building materials — with affected drywall on the ceiling and along the wall bases, spotting on the wood joists and subfloor above the ceiling, and a duct system that had been circulating air through the affected area. Because the basement was finished and full of stored contents, the plan started with a complete pack-out before any demolition.
All work followed the ANSI/IICRC S520 Standard for Professional Mold Remediation, the same protocol behind every mold remediation service we perform, with photos documented at each phase.

See Our Full Process →Under the IICRC S520 standard, Condition 3 means actual mold growth is present on building materials, not just settled spores. It calls for full engineering controls, removal of affected porous materials and physical cleaning of what stays.
Growth and moisture travel inside drywall paper and insulation beyond what shows on the painted face. Removing past the visible line reaches clean, dry material and avoids leaving a colonized edge behind the new ceiling.
In a Condition 3 space, demolition disturbs spores that settle on anything left in the room. Moving contents out, and wiping or bagging them on the way, keeps the stored items from becoming the next problem.
An EPA-registered microbial-resistant coating is applied to remediated wood to resist future growth. It is applied only after the framing has been physically cleaned and dried; it is never used to cover visible mold.
Supply and return ducts in the affected zone carry spores to the rest of the house and back into the cleaned room. Sealing them during the work and cleaning and treating them afterwards keeps the system from re-seeding the basement.
From a water-damaged ceiling to growth at the floor line, our IICRC-certified team remediates finished basements across Montgomery County — contents, framing and ductwork included. Written estimate, no obligation.
