ABOUT THE SERVICE
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.
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.
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.

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.
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.
Any pipe burst, roof leak, basement flooding, or appliance failure in the past 48 hours. 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.

From $249FAQ
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 testing to any inspection for an additional $100+.
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.
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.
Yes — but for a different reason than most people expect. Visible mold doesn't need to be proven (EPA guidance says sampling just to confirm visible growth is usually unnecessary). The inspection's real job is finding the moisture source, tracing how far growth extends into materials you can't see, and defining an accurate remediation scope. What's visible is often a fraction of what's there.
