If your home’s starting to smell musty, you’re seeing stains on drywall, or you just want peace of mind that the air you’re breathing is safe, a professional mold inspection is the right move.
I handle mold inspections and testing in Shiloh, PA, and throughout nearby areas like West Manchester Township, Weigelstown, Dover, and York. You’ll get straightforward, data-backed answers — no scare tactics, no pushy sales pitch.
Every inspection starts the same way — with a careful walk-through of your home, top to bottom. I check the places where mold hides: basements, attics, crawl spaces, HVAC systems, and any areas where moisture might linger.
Using thermal imaging and moisture meters, I can find damp spots that often go unnoticed until they become bigger issues.
If testing is needed, I’ll collect air and surface samples and send them to an independent, accredited lab.
When the results come back, you’ll get a detailed report that spells out:
What kind of mold (if any) was found
How serious the problem is
What’s causing it
What to do next
The report’s written in plain language — no technical jargon, just clear information about what’s going on inside your home.
Mold doesn’t always show up as dark patches on a wall — sometimes it’s hiding behind drywall, under flooring, or in the air. A professional mold inspection and testing service in Shiloh, PA gives you real answers about your home’s condition before the problem spreads or gets expensive.
I work with:
Homeowners who notice musty smells or visible mold
Buyers and sellers dealing with real estate inspections
Property managers who need regular indoor air quality checks
A mold inspection helps you understand what’s happening, not guess at it — so you can make smart, confident decisions about your property.

If the lab report shows elevated mold levels, there’s no reason to panic — it’s just information. The report will tell you what’s going on, where it’s coming from, and what’s feeding it.
Since I don’t sell remediation, I have no incentive to exaggerate the problem. My goal is simple: give you accurate information so you can make informed choices.
If it’s minor, I’ll tell you that. If cleanup isn’t needed, I’ll tell you that too. You’ll know what’s real and what’s not — without fear or pressure.
Homes in Shiloh, PA experience plenty of humidity and older construction — perfect conditions for moisture buildup.

I’m Tom Duff, the owner and lead mold inspector serving homeowners and businesses here in York County. I’ve been doing this work for more than 17 years and have personally completed over 8,000 mold inspections across homes, offices, and commercial spaces throughout the area.
Before mold inspections became something people really talked about, I was already deep in the restoration and environmental cleanup world. That background gave me a real-world understanding of how moisture moves through buildings — and how small leaks or bad repairs can quietly cause big problems over time.
Over the years, I’ve seen it all — from slow plumbing leaks hiding behind kitchen cabinets to serious water damage spreading through large commercial buildings. Those experiences shaped the way I inspect today: focused, detailed, and data-driven.
My work has even been featured on HGTV and the DIY Network, including the show Rescue My Renovation, where my team and I tackled real mold issues on camera. We helped homeowners recover from bad cleanup jobs and negligent contractors, showing what proper mold inspection and testing actually look like — and why cutting corners always backfires.
These days, I still approach every inspection the same way. I take my time, explain what I’m seeing, show you the readings and lab results, and make sure you understand exactly what’s going on in your property. No upselling. No scare tactics. Just clear information you can trust.
