Mold Remediation. Independently Verified.

Every ZeroSpore project is tested by a separate accredited laboratory. We don't grade our own work. You get proof, not promises.

How ZeroSpore Works

Every project follows the same four-step protocol. No shortcuts. No guesswork. No exceptions.

01
Professional Assessment $399

We inspect the affected area, map moisture conditions, identify the mold type and extent, and develop a remediation protocol specific to your home. You receive a written report and a detailed scope of work with fixed pricing — not an estimate, not a range.

02
Contained Remediation

Our crew seals the affected area under negative air pressure, removes or treats contaminated materials, runs HEPA filtration throughout the process, and applies antimicrobial treatment to all affected surfaces. Every step follows IICRC S520 standards.

03
Independent Lab Testing $350

After remediation, we do not test our own work. A separate accredited laboratory collects air and surface samples from the treated area and issues a clearance report. This is part of every ZeroSpore project. It is not optional.

04
Documentation Package

You receive a complete package: scope of work performed, before-and-after photos, independent lab clearance results, and a certificate of completion. Everything a buyer, seller, lender, or insurer needs — in one file.

Assessment credit: If you proceed with a remediation project of $3,500 or more, the $399 assessment fee is credited in full toward your project.

What Does It Cost?

Every home is different. We provide fixed-price quotes after an on-site assessment — never over the phone, never based on photos alone. Here are typical project ranges.
