“When mold is in your home or building, “trust me” isn’t good enough. You deserve proof.
As a service extension of Zavza Seal, an informational hub for questions and concerns about mold, and removal of and prevention of household and workplace mold, very project we take on is backed by state licensing, federal safety certification, and building-science training — held to standards you can check for yourself. Below is exactly who certifies us, what each credential means, and why it protects you.”

Serving homeowners, landlords, and businesses across Long Island and the greater New York City area.
Mold remediation is one of the few home services where the state of New York actually requires a license, and for good reason. Done wrong, mold work can spread spores through a building, disturb hazardous materials, and leave the underlying moisture problem untouched, so it all comes back a few months later.
New York’s mold law was written to protect you from exactly that. It sets minimum work standards, requires proper containment and documentation, and, importantly, keeps the people who inspect for mold separate from the people who get paid to remove it, so no one has an incentive to oversell the work.
We built Zavza Seal to meet those standards and then go past them. Here’s the paperwork to back it up.
New York State Mold Remediation Contractor License
When you team up with Zavza Seal, you’re teaming up with a dedicated and caring contractor the state has vetted and can hold accountable, not an unlicensed operator working outside the law. Read some of our reviews on Google Maps here.

Why this work is personal
Jake spent a year sick before anyone thought to check for mold
Jake is our field manager — the one who runs our crews and walks into homes every single day. But before any of that, he spent nearly a year feeling like he just couldn’t shake the flu.
He saw eight different doctors. Every one of them treated it like a virus or an infection — another round of antibiotics, another flu medication, another “give it a couple weeks.” Nothing worked, because none of it was the actual problem.
It wasn’t until someone finally ordered a mold test that it clicked. The results led straight back to his own home — where mold had been growing behind a wall the entire time. No smell he could place, no stain, nothing you’d ever notice just living there. It was completely hidden, and it had been making him sick for months.
“Eight doctors and a year of antibiotics — and the whole time it was mold behind a wall I couldn’t even see.” — Jake, Field Manager
Once the mold was gone, Jake got his health back. That’s a big part of why he does this work the way he does — because he knows firsthand that what’s behind the wall matters just as much as what you can see.
