If your home smells musty, you’ve got spots on the drywall, or you just want to know what’s going on behind the walls, a professional mold inspection is a smart first step.
I handle mold inspections and testing in York, PA, and all across the area — West Manchester, Shiloh, Dallastown, Dover, Red Lion, and surrounding towns. You’ll get straightforward answers based on real data, not guesses or sales pressure.
Every inspection starts with a full walk-through of your home. I look at your areas of concern, then I check the areas that matter most — attics, basements, crawl spaces, and anywhere moisture tends to hide. I use moisture meters and thermal imaging to find hidden dampness that you can’t always see.
If I think testing is needed, I’ll take air or surface samples and send them to an independent, accredited lab for analysis. Once the results come back, you’ll get a simple report that shows:
What kind of mold was found (if any)
How serious it is
What’s causing it
What to do next
Everything’s laid out in plain English. No scare tactics, no overcomplicating it — just clear information you can actually use.
You can’t fix what you can’t see. Mold isn’t always visible — sometimes it’s behind drywall, under flooring, or floating around in the air.
A mold inspection and testing gives you real data about what’s happening inside your home instead of guessing based on what you smell or see.
I work with all kinds of clients in the York area — homeowners dealing with past leaks, people buying or selling houses, and property managers who just want to stay ahead of potential issues.
A professional mold inspection in York, PA helps you:
Identify hidden moisture or humidity problems
Confirm if mold levels are normal or elevated
Understand what’s causing the issue
Make informed decisions before spending money on repairs
If testing confirms mold growth or elevated spore levels, don’t panic.
That doesn’t automatically mean you’ve got a disaster — it just means you have solid information to work with.
Your report will show exactly where the problem is and what’s feeding it.
Because I don’t do remediation, there’s no reason for me to exaggerate the issue. My job is to help you understand what’s happening so you can decide what’s next — calmly, with facts in front of you.
If it’s small, I’ll tell you that. If you don’t need cleanup, I’ll tell you that too.

I’m Tom Duff, the owner and lead mold inspector here in York. I’ve been at this for over 17 years and have done more than 8,000 mold inspections in homes, offices, and commercial buildings.
I got my start in restoration and environmental cleanup long before mold inspections became a thing people really talked about. Over the years, I’ve seen just about everything — from slow leaks hiding behind kitchen walls to major water damage inside big commercial spaces.
I’ve been trusted by and featured on HGTV and DIY Network, where my team and I handled real mold inspections and remediation projects on camera. On the show Rescue My Renovation, we helped homeowners fix mold problems caused by bad cleanup jobs and neglegent contractors. It was a chance to show people what proper mold inspection and testing actually look like — and why cutting corners always ends up costing more later.
These days, my approach hasn’t changed much. I take my time, explain what I’m seeing, show you the data, walk you through the lab results, and make sure you fully understand what’s going on in your property. No pressure, no upselling.
