Basement Mold Inspection
Most of the mold calls I get in York County start in the basement. I come out, test it, and tell you what is actually there — I do not sell remediation, so there is nothing for me to talk you into.
What's included
Crawl Space Mold Inspection
Nobody goes in their crawl space, which is exactly why problems sit down there for years. I'll go in, take readings, pull samples, and show you photos of what's under your floor.
What's included
Attic Mold Inspection
Attic mold usually isn't a leak. It's ventilation, and a bath fan dumping wet air into the attic instead of outside. I'll find which one it is and document it.
What's included
Bathroom Mold Inspection
Surface mildew on grout is normal and you can clean it yourself. What I look for is the water that got behind the tile, under the vanity, or into the subfloor.
What's included
Real Estate Mold Inspection
Somebody flagged mold and now the deal is stuck. I test it, the lab analyzes it, and you get a report in one to two business days that both sides can actually use.
What's included
Mold Clearance Testing
The contractor says it's done. Clearance testing is how you find out. I'm not connected to whoever did the work, so the result is just the result.
What's included
Commercial Mold Inspection
Offices, apartment buildings, schools, restaurants, warehouses. Independent testing and documentation you can put in a file, send to a tenant, or hand to your insurer.
What's included
Landlord / Tenant Mold Inspection
Rental mold arguments go in circles until somebody brings numbers. I test the unit, the lab analyzes it, and both sides get the same report.

A bedroom or living room that just feels stuffy often needs more than a mold sample. Room-by-room readings of CO2, fine particulate and dust show which rooms stand out and whether ventilation is part of the story — clues that targeted mold testing alone won't give you. Available on inspections in the city of York and across the county. If it's a sleep-room issue, see how indoor air affects sleep.
- PM1.0
- PM2.5
- PM10
- CO2
- TVOC
- Formaldehyde screening
- Relative humidity
- Temperature
Particle readings point to common household sources consistent with the particle-size pattern observed. They don't identify a particle as mold, dust, pollen or pet dander.

Rated 5.0 from 5 Google reviews.
I could not recommend this business enough for mold inspections! If you're looking for quick turnaround, great communication and honest upfront service - this is your place. Tom was respectful, professional, and explained everything in great detail.
Truly the best! I can't say enough good things about Tom. I truly feel like I had someone I could count on by my side during this very stressful situation.
We had a great experience with Tom at Mastertech throughout this whole process. They took extra time to answer all of our questions and explained everything in a way that actually made sense.
Questions I get asked a lot
Call or text and describe what's going on. Most of the time the area you're worried about picks the inspection for you — basement, crawl space, attic, bathroom. If it's a real estate deal or a dispute, that changes the report more than the fieldwork.
Where I work
I cover York and the towns around it — basically anything within about 7 miles of 2400 Taxville Rd, York, PA 17408, plus a good bit of York County beyond that. If you're close and don't see your town, call me anyway.
Based in York, not a call center
You reach me directly, and I'm the one who shows up and does the inspection. Most weeks I can be out within a couple of days, sooner if you're up against a closing date.
