Mold Remediation Protocol
What a Mold Remediation Protocol Is — and Why It Matters
A mold remediation protocol (MRP) is a written document prepared by a licensed mold assessor that specifies what work a remediation contractor must perform to address a confirmed mold contamination. It defines the scope, methodology, containment requirements, personal protective equipment (PPE), clearance criteria, and verification requirements for a specific mold remediation project. Under Florida Administrative Code Rule 61-31.702, a mold remediation protocol is a required element of regulated mold remediation work in Florida.
Most homeowners and property managers dealing with mold do not know this document exists, let alone that it is supposed to govern what the remediation contractor does. The result is that many mold remediation projects are performed without a protocol — meaning the scope is determined entirely by the contractor with no independent specification of what work is required, how it should be performed, and what success looks like.
What a mold remediation protocol contains
A proper mold remediation protocol under Florida standards should document:
- Scope of contamination: Specific identification of affected materials, locations, and approximate quantities requiring remediation, based on the preceding assessment findings and laboratory results
- Containment requirements: Specification of containment type and boundary appropriate to the contamination level — limited (single-barrier polyethylene sheeting), full (floor-to-ceiling containment with negative air pressure), or enhanced (full containment with additional engineering controls)
- PPE requirements: Minimum personal protective equipment requirements for workers performing the remediation based on contamination level
- Remediation methodology: How affected materials are to be treated — removal (HEPA vacuuming plus physical removal of contaminated materials), HEPA vacuuming with antimicrobial treatment, or encapsulation for specific materials where appropriate
- HEPA air filtration requirements: Specification of air scrubber or negative air machine requirements during remediation to capture airborne particles
- Clearance criteria: Definition of what constitutes successful remediation — typically visual clearance (no visible mold growth), moisture clearance (building materials at acceptable moisture content), and air sampling clearance (indoor spore counts consistent with outdoor background per IICRC S520 criteria)
- Post-remediation verification requirements: Specification that clearance testing is to be performed by an independent mold assessor separate from the remediating contractor
Why having an independent protocol protects property owners
When a remediation contractor determines their own scope of work, the financial incentive is to maximize the scope — more materials removed, more square footage treated, more equipment deployed, more days on site. Without an independent protocol specifying what actually needs to be done, there is no external check on whether the proposed scope matches the actual contamination.
An independently prepared mold remediation protocol from a licensed FL Mold Assessor (MRSA):
- Defines the scope based on assessment findings and laboratory data rather than contractor financial interest
- Gives property owners a specification against which to solicit and compare bids from multiple contractors
- Provides contractors with clear instructions that protect them from later claims that work was insufficient
- Establishes clearance criteria that define project completion objectively rather than leaving it to the contractor’s judgment
- Creates a documented record of what was specified versus what was performed — essential for insurance claims, HOA disputes, and real estate transactions
How mold remediation scope levels are defined
IICRC S520 defines remediation scope levels based on the extent of contamination:
- Level 1 (small isolated areas): Less than 10 square feet. Limited containment. Can often be addressed by property owners following EPA guidance, though professional remediation is advisable.
- Level 2 (mid-sized isolated areas): 10–100 square feet. Full containment required. Licensed remediator required under Florida law.
- Level 3 (large areas): Greater than 100 square feet or entire HVAC systems. Full containment with enhanced engineering controls. Licensed remediator with appropriate methodology required.
Requesting a mold remediation protocol from Coastal Air Assessments
Following a mold assessment that identifies contamination requiring professional remediation, Coastal Air Assessments prepares a mold remediation protocol as part of the assessment deliverable. The protocol specifies scope, methodology, containment level, and clearance criteria based on the specific findings and laboratory results from your property.
If you have already received a remediation bid from a contractor and want an independent protocol to verify whether the proposed scope is appropriate and correctly specified, we can prepare a stand-alone protocol based on the assessment findings. We can also review contractor remediation plans against IICRC S520 standards and identify any gaps before work begins.
Frequently Asked Questions
Is a mold remediation protocol legally required in Florida?
Florida Administrative Code Rule 61-31.702 requires that mold remediation work be conducted in accordance with a written remediation protocol prepared by a licensed FL Mold Assessor. Under Florida Statute 468.8419, the same company cannot prepare the protocol (assessment) and perform the remediation on the same property within 12 months. In practice, many residential mold projects in Florida are performed without a formal protocol — which creates risk for property owners and exposes contractors to liability.
Can I use the remediation protocol to get bids from multiple contractors?
Yes — and this is one of the most valuable uses of an independent protocol. A written specification from a licensed assessor defines exactly what needs to be done. Multiple contractors can bid against the same specification, giving you an apples-to-apples comparison rather than comparing bids that differ in scope, methodology, and assumptions. Properties where remediation is being done for insurance claims often require this documentation.
What happens if a remediation contractor doesn't follow the protocol?
If a contractor performs work that deviates from the specified protocol — remediating less than the specified scope, using inadequate containment, or skipping required steps — that deviation is documented when post-remediation verification is performed. If clearance criteria are not met, the contractor is responsible for additional work. The written protocol is the contractual specification against which the work is evaluated. Without it, there is no objective standard.
Do I need a new protocol for each remediation project?
Yes. A mold remediation protocol is specific to a particular contamination event, a particular building, and a particular set of findings. It cannot be reused for a different project. If mold recurs in the same building after remediation due to an unresolved moisture source, a new assessment and a new protocol are required for the subsequent remediation.
