If you’re noticing that stubborn musty smell that won’t go away, or you’re worried about an old water issue or indoor air quality, it might be time for a professional mold inspection.
I handle mold inspections and testing in Spring Garden Township, PA, and throughout York County — including York City, East York, and surrounding communities. You’ll get clear, straightforward results based on real data so you know exactly what’s going on inside your home.
Every inspection starts with a thorough walkthrough of your property — not just the visible areas. I check basements, attics, crawl spaces, HVAC systems, and behind plumbing fixtures where moisture tends to hide.
Using thermal imaging and moisture mapping, I can detect leaks and damp spots that often lead to hidden mold growth. If testing is needed, I’ll collect air or surface samples and send them to an independent, accredited lab for certified analysis.
Once the results come back, you’ll get a clear, detailed report that outlines:
What type of mold (if any) is present
How significant the issue is
What’s likely causing it
Practical next steps for your property
Everything is explained in plain language so you actually understand what’s happening — no confusion, no technical fluff.
Mold isn’t always visible, and it doesn’t always smell. It can hide in walls, flooring, or ductwork for months before showing up. A professional mold inspection and testing service in Spring Garden Township, PA helps you identify what’s really going on.
I regularly work with:
Homeowners dealing with musty odors or past leaks
Buyers and sellers during real estate transactions
Property managers who need documentation for tenants
Getting a proper inspection means getting real answers — not guesses.

If the lab results confirm mold, don’t panic — it doesn’t automatically mean you’ve got a huge problem. The report will explain what type of mold it is, how elevated the levels are, and what might be causing it.
Since I don’t perform remediation work, I have no reason to exaggerate the results or suggest unnecessary cleanup. If it’s minor, I’ll say so. If it needs attention, I’ll point you toward qualified professionals who can handle it properly.
Homes around Spring Garden Township vary — some are historic, others newer builds — but they all deal with the same local moisture challenges.

I’m Tom Duff, the owner and lead inspector at Mastertech Environmental of York.
Before starting Mastertech, I spent almost ten years in the Fire Department, where I learned how buildings are built and what happens when water or humidity gets trapped inside them.
After that, I spent six years working in pest control and environmental cleaning, gaining hands-on experience with the kinds of moisture and ventilation issues that often lead to mold.
I founded Mastertech because I grew up dealing with mold-related illness myself.
That personal experience shapes how I approach every job — carefully, methodically, and with the goal of helping people understand what’s really going on in their homes.
Each inspection is about clarity and education. I’ll show you what I’m seeing, explain what the data means, and help you understand the next step that makes sense for your situation.

Before I started Mastertech, I spent nearly a decade in the Fire Department, where I learned how homes are built — and how water, smoke, and humidity affect them from the inside out.
After that, I worked for about six years in pest control and environmental cleaning, which taught me how moisture issues quietly grow into bigger problems.
I started Mastertech to help people dealing with mold because I know firsthand what it’s like. I grew up with mold-related illness, so I understand it from both sides — as a professional and as someone who’s lived through it.
