Commercial mold problems are usually documentation problems too
When mold shows up in a commercial building, there's almost always somebody who needs paperwork: a tenant who complained, an employee who filed something, a property manager reporting to an owner, an insurance adjuster, or a lawyer.
So a commercial inspection has to do two jobs. Find out what's actually going on, and document it well enough to stand up when somebody else reads it months later.
I handle inspection and testing only — no remediation — which means the report is a findings document, not a proposal. That tends to matter a lot when there's a dispute involved.
Tell me what's going on and I'll come back with details and pricing.
When commercial buildings need testing
- Tenant or employee complaints about musty smells or air quality
- A water loss — burst pipe, roof leak, sprinkler discharge, storm flooding
- Visible growth on drywall, ceiling tile, or behind millwork
- HVAC issues, condensate overflow, or mold reported at supply registers
- A lease dispute or habitability complaint that needs third-party findings
- Insurance or legal proceedings requiring independent documentation
- Due diligence before buying or leasing a building
- Verification after a remediation contractor finishes
What drives mold in commercial buildings
Flat roofs and roof drains
Ponding water and clogged drains put moisture into the deck and the ceiling below it, often unnoticed for months.
HVAC and condensate
Overflowing pans, unlined ductwork, poor drainage, and systems running to hit a temperature rather than manage humidity.
Buildings running unoccupied
Setback schedules, vacant suites, and weekend shutdowns let humidity climb with nobody there to notice.
Plumbing in shared walls
Multi-tenant buildings hide leaks in chases and demising walls where nobody owns the problem.
Kitchens, restrooms, and wet processes
Restaurants, salons, and medical spaces put constant moisture into the building.
Below-grade space
Basements, garages, and storage levels with foundation moisture and little air movement.

Property managers and multi-unit buildings
If you manage rentals, you already know a mold complaint has two parts: making sure the building is actually okay, and being able to show that you took it seriously. Independent testing does both.
I can inspect a single unit, a unit plus the ones around it, or a whole building, and keep the reports separate so you can share only what's relevant to each tenant.
Indoor Air Quality Testing for Offices and Commercial Spaces
In offices, conference rooms and tenant suites, CO2 is often the first sign a space isn't getting enough fresh air, and TVOC screening can flag areas near storage, printing or a recent build-out. Comparing rooms shows which spaces stand out, giving clues beyond mold sampling alone. For what the lab side can and can't show, read what mold testing tells you about indoor air.
- 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.

What people say after an inspection
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.
