Mold doesn’t just affect homes — it can silently spread through offices, warehouses, restaurants, and other commercial properties. And in a city as dynamic and humid as New York, mold can become a serious health and business risk if not detected and handled properly.
At Zavza Seal, we specialize in commercial mold testing, inspection, cleanup, and removal services across Long Island, Brooklyn, Queens, and the Bronx. In this blog, we’ll explain why mold testing is vital for your business, what the process involves, and how we helped one Brooklyn business recover after a mold emergency.
Why Commercial Mold Testing is Crucial
Mold is more than just an eyesore.
In commercial settings, mold can:
- Trigger allergies and respiratory problems among employees and customers.
- Damage walls, ceilings, and inventory.
- Lead to potential lawsuits and fines if it violates health and safety codes.
- Force closures and loss of revenue during remediation.
By investing in commercial mold testing, you’re taking the first, smart step toward keeping your property safe, compliant, and operational.
Common Causes of Mold in Commercial Properties
New York’s unique climate and aging infrastructure create the perfect conditions for mold to grow. Here are a few reasons businesses turn to us for commercial mold inspection:
- Leaky roofs, pipes, or HVAC systems
- Poor ventilation
- Flooding or water intrusion
- High indoor humidity levels
- Unnoticed water damage after a storm
Our team of certified specialists knows how to identify these risks before they spiral into expensive problems.
The Commercial Mold Testing Process
At Zavza Seal, we follow a comprehensive and transparent process for commercial mold inspection and testing:
Step 1: Initial Consultation
We start by discussing your concerns, walking through the property, and identifying visible signs of mold or water damage.
Step 2: Moisture Detection
Using advanced moisture meters and infrared cameras, we pinpoint hidden moisture sources that could foster mold growth.
Step 3: Air & Surface Testing
We take air samples and swabs from suspected areas and send them to certified labs for analysis. This helps us identify the type and concentration of mold present.
Step 4: Detailed Report
Within a few days, you’ll receive a full report of our findings, including lab results, risk assessment, and recommended next steps.

📖 Case Study: Helping a Brooklyn Restaurant Reopen After Mold Infestation
One of our most memorable projects involved a family-owned restaurant in Williamsburg, Brooklyn.
The Problem:
The owner called us after noticing a musty smell in the dining area. Their employees were reporting allergy symptoms, and a city health inspector had warned them about possible violations.
We performed a full commercial mold inspection and discovered extensive mold behind the drywall and under the flooring, caused by an undetected leak in the kitchen. Air tests revealed high levels of Aspergillus spores, which can cause serious respiratory issues.
The Solution:
Our team:
- Contained the affected areas to keep spores from spreading into the kitchen and dining room.
- Removed contaminated drywall and flooring safely.
- Treated all surfaces with EPA-approved antimicrobial solutions.
- Fixed the leak and installed dehumidifiers to lower moisture levels.
- Conducted post-remediation testing to ensure the space was safe.
The Result:
The restaurant passed their health inspection, reopened quickly, and the owner even reported better air quality than before.
