ABOUT THE SERVICE
Mold Pro Solutions is an IICRC-certified mold inspection company serving Montgomery County, MD. A professional mold inspection is a comprehensive evaluation of your property by an IICRC-certified technician using advanced diagnostic equipment — including FLIR thermal imaging cameras, professional-grade pin and pinless moisture meters, hygrometers, and borescope cameras — to identify current mold growth, hidden moisture intrusion, and conditions likely to cause future contamination. Our guide to the seven moisture sources behind household mold shows what that search covers.
Unlike a basic visual check, our inspection examines areas you can’t see: inside wall cavities, beneath flooring, around HVAC systems, in crawl spaces, and behind insulation. In Montgomery County — where a significant percentage of homes feature aging waterproofing systems that have exceeded their design life — hidden moisture intrusion is extremely common even in homes that appear dry on the surface. Our guide to how long it takes mold to grow after a leak explains why a dry-looking surface can hide an active problem.
The region’s high humidity and proximity to the Potomac River watershed mean that mold can establish in any home, regardless of age or price point. From the historic stone foundations in Bethesda to the modern developments in Silver Spring, we’ve inspected every type of residential construction in the county to ensure homeowners have the certainty they need.
| Annual rainfall | 41+ inches |
| Summer humidity | 65–74% RH |

| Mold growth starts | 24–48 hrs after moisture |
WARNING SIGNS
Mold often grows hidden behind walls, under flooring, and in crawl spaces. These signs indicate you should call a certified inspector immediately.
Black, green, or white patches on walls, ceilings, or around windows. Even small spots can indicate a much larger colony behind the surface — visible mold is often just the tip of the iceberg. Before reaching for a household cleaner, see our guide on how to clean a small mold area safely and when a patch is too big for DIY.
A lingering earthy or musty smell, especially in basements, bathrooms, or near HVAC vents. In Montgomery County homes with aging ductwork, mold inside HVAC systems is a common hidden source of musty odors throughout the house; when the inspection confirms it, our air duct cleaning team clears the system. Our guide to musty basement and hidden mold warning signs explains what to check first. If the smell is strongest at floor level, read about a musty crawl space and hidden moisture. For a musty odor with no visible source, start with what a persistent musty odor means.
Any pipe burst, roof leak, basement flooding, or appliance failure in the past 48 hours. A roof leak often shows up first in the attic; our guide to what an attic mold inspection checks explains where to look. Montgomery County’s heavy summer storms regularly cause flash flooding in neighborhoods near Watts Branch, Willett Branch, and Rock Creek tributaries.
Sneezing, coughing, eye irritation, or worsening asthma/allergies that improve when you leave home. Airborne mold spores from species like Aspergillus and Penicillium — common in Montgomery County homes — trigger respiratory reactions in sensitive individuals.
A pre-purchase mold inspection protects buyers from hidden remediation costs. For sellers, a clean inspection report provides confidence and accelerates closings. Especially important for older homes in Kenwood, Potomac Village, and other established neighborhoods.
After any mold remediation work, a clearance inspection confirms spore counts have returned to normal background levels. This documentation protects you during home sales and insurance claims.

Why no test for mold you can see? EPA guidance says that “in most cases, if visible mold growth is present, sampling is unnecessary,” and suggests considering sampling in specific situations instead, such as when litigation is involved, the source of the mold is unclear, or health concerns are a problem. Sources: EPA – Mold Testing or Sampling • EPA Mold Course, Chapter 3
INDEPENDENT CHECKS
You don’t have to take our word for it: any samples from your home are analyzed outside our company, and after remediation an outside inspector you pick can confirm the result. A Mold Pro Solutions technician handles the inspection itself — the walk-through, thermal imaging, moisture readings, and photos in your written report. The samples we collect go to an independent laboratory accredited under the AIHA-LAP, LLC EMLAP program, and that laboratory is named on the report you receive. If lab results point toward remediation, those numbers don’t come from the company that would do the work.
Your report also states plainly when remediation isn’t needed. When it is, compare our written estimate with other quotes before you decide — there’s no obligation. And if you hire Mold Pro Solutions, we accept third-party post-remediation verification, so you can have an independent inspector of your choice check the finished job.

Most residential inspections in Montgomery County take 1–2 hours, depending on property size and complexity. Larger homes common in Potomac and Bethesda (3,000–6,000+ sq ft) may take 2–3 hours for a thorough assessment. We never rush an inspection — thoroughness is the entire point.
A mold inspection is a visual and instrument-based assessment to find mold growth and moisture sources. Mold testing involves collecting air or surface samples that are sent to an AIHA-accredited laboratory to identify specific mold species and spore concentration levels. We offer both services and can add lab sampling to any inspection: surface sampling for $150 or an air quality check for $300.
You can look for visible mold, but professional inspectors use FLIR thermal imaging cameras (professional instruments) and calibrated moisture meters to detect hidden moisture behind walls, under floors, and in ceiling assemblies — areas invisible to the naked eye. In Montgomery County homes with 50–80 year old construction, the most dangerous mold is almost always hidden inside wall cavities and under materials.
We strongly recommend it, especially for homes built before 1980. A standard home inspection does not include detailed mold assessment with thermal imaging and moisture meters. Given that approximately 45% of Montgomery County homes were built before 1970, a pre-purchase mold inspection can identify costly hidden problems before you close — potentially saving tens of thousands in remediation costs.
Most homeowner policies do not cover inspection costs directly. However, if mold is discovered and resulted from a covered peril (like a sudden pipe burst), the inspection cost may be reimbursable as part of the overall claim. We provide detailed documentation with moisture readings, photos, and lab results that meet the requirements of all major insurance carriers in Maryland. Read when a mold claim is covered and when it is not before you file.
We offer same-day inspections when you call before noon. Next-day appointments are almost always available. For active water damage emergencies, we dispatch within 60–90 minutes, 24/7. We serve all Montgomery County addresses from Potomac to Silver Spring, Bethesda to Olney.
You receive a detailed written report documenting all findings with photos and moisture readings, plus a clear recommendation for next steps. If remediation is needed, we provide a transparent written estimate. If remediation is NOT needed, we tell you honestly — we’d rather earn your trust than sell unnecessary work.
Yes. Our inspection reports are specifically formatted for use in real estate transactions, insurance claims, and legal proceedings. We are an IICRC Certified Firm with Maryland state licensing, and our reports include calibrated instrument readings, photo documentation, and lab results (when testing is included) that meet the evidentiary standards required by all parties.
Pricing follows our current inspection offer — when the standard fee applies, it's fully credited toward remediation if you proceed with us, so the inspection effectively costs nothing when work is needed. A comprehensive tier with air sampling is available at $349. Check the booking form above for today's offer, or call (301) 351-4508.
Not to prove it is there: EPA guidance says sampling just to confirm visible growth is usually unnecessary, and a free remediation estimate is the faster first step. An inspection earns its fee when the moisture source or the extent behind finishes is unclear — it maps how far growth extends into materials you can't see and defines an accurate remediation scope. What's visible is often a fraction of what's there.
Look for IICRC-certified inspectors, a written report with photos and moisture readings delivered within 24 hours, samples sent to an independent AIHA-accredited laboratory that is named on the report, and a clear statement of when remediation is not needed. The fee should be credited if you proceed with remediation, and booking the inspection should never commit you to hiring the same company for the work. Mold Pro Solutions meets each of these points.
Yes. Mold Pro Solutions accepts third-party post-remediation verification, which means an independent inspector you select can run clearance testing once the work is finished. That way, confirmation that the job worked comes from someone other than the company that did it.
No, and an inspector who always does is selling remediation. Many of our inspections in Montgomery County end with a report that says no active growth was found and names what to watch; the rest get a located, measured finding and a written scope. Mold spores are in every house, so the question an inspection answers is not “is there mold” but “is there growth, where is the moisture feeding it, and does it need professional removal”. Our report states plainly when the answer is that no remediation is needed.
No. A moisture meter and a thermal camera find where water is or has been, which is where mold grows, but they do not detect mold itself. That is why the inspection combines them: moisture mapping and thermal imaging point to the wet spots, and the visual assessment and, when needed, air or surface sampling confirm whether growth is present. A wet reading with no visible growth is still worth acting on, because growth can begin within 24–48 hours of a material getting wet and stay hidden inside the cavity.
Without demolition first. Under carpet: a musty smell that is strongest near the floor, discoloration or stiffness at the edges, and a moisture reading through the carpet are the triggers; lifting a corner at a closet or a wall edge shows the pad and the subfloor. Behind walls: moisture readings along the base of the wall, thermal imaging that shows the cooler wet area, staining or bubbling paint, and an air sample in the room compared with outdoors. When those agree, a small inspection opening confirms the extent before any scope is written. Carpet pad that has been wet is removed rather than cleaned, because it cannot be dried in place. Our guide to how to tell if you have mold in your house lists the other hidden spots.
That is when it earns its fee. Visible mold tells you what to remove; the inspection is for the cases where you have a musty smell, allergy-type symptoms at home, a past leak, a damp basement or a purchase decision and no visible growth to point at. Thermal imaging and moisture mapping find the wet area behind the finish before it becomes a demolition job, and a report that finds nothing is a documented baseline for a sale or an insurance claim. If the inspection does find growth, the fee is credited toward the remediation.
