Mold Remediation Protocol Template: Sections, Example Language and the IICRC Basis

A mold remediation protocol, which remediators often call the mold removal protocol or the scope of work, is the document the assessor writes and the contractor works to. It turns the assessment's findings into instructions: which areas, which materials, what containment and protective equipment, how each material is removed or cleaned, how dry it has to be, and what the assessor will check before the job is cleared. A proper mold remediation protocol is one a contractor can price and perform without calling you, and one the clearance visit can measure the finished job against. Why the protocol has to derive from the assessment, and why the moisture fix is the element most often dropped, is covered in remediation protocol writing. This page is the template: the sections, in order, with example language for each.

Bracketed text in the examples is a placeholder, and the figures are illustrative. The finished version of this document, produced for a demonstration job, is the sample remediation protocol (PDF).

What the IICRC standards for mold remediation give you, and what they don't

IICRC S520, the Standard for Professional Mold Remediation, is the consensus standard a protocol is read against; the current version is the 2024 ANSI/IICRC revision (IICRC, S520). It supplies the condition categories, the remediation goal of returning affected areas to normal fungal ecology, the principle of correcting the moisture source, containment and protective controls scaled to the work, and independent post-remediation verification. It does not supply a fill-in protocol, a numeric spore-count pass mark or a fixed moisture percentage. IICRC S500, the water damage standard, supplies the water categories and classes and the comparative dry-standard method used for drying targets. The EPA's Mold Remediation in Schools and Commercial Buildings is the freely available companion most protocols also cite. Cite these documents by name, and by section only if you have read that section.

1. Project information and scope of work

Identify the property, the client, the assessment report the protocol derives from (by date), and the assessor. Summarize the affected areas and their total by condition, the moisture source, the sequencing, and, where it applies, the estimated cost and timeframe. New York requires the cost estimate and timeframe in the plan (NY Labor Law §945); elsewhere they are optional, and a figure should come from the job, never be guessed.

This protocol derives from the Mold Assessment Report for [address] dated [date]. It covers [n] areas: [list] at Condition 3, approximately [x] sq ft in total, and [area] whose condition is not determined, approximately [y] sq ft, scoped below with an investigative step. The moisture source is [source]. Remediation does not begin until [type of contractor] has corrected the source and documented the work. Estimated cost: [amount or "to be provided by the contractor"]. Estimated timeframe: [duration].

2. Affected areas, S520 condition and the remediation goal

A table, one row per area: area, S520 condition, approximate quantity, materials, and the action. The conditions are the ones the assessment assigned; the protocol does not raise or lower them, because two signed documents that disagree on the condition of an area disagree on the fact that sets containment and PPE. The goal for every area is a return to Condition 1, normal fungal ecology (IICRC, S520; see condition categories).

Condition 3 (actual growth) gets the removal-and-containment procedures below. Condition 2 means primarily settled spores or fragments that originated from a Condition 3 area, which may include traces of actual growth but no established colony; it is cleaned (HEPA vacuuming and damp wiping, with porous materials that cannot be cleaned removed). An area where growth is suspected but not confirmed is not Condition 2. Its condition is not determined, and its procedure starts with an investigation and an outcome rule.

Hallway ceiling junction: investigative step. Under the controls of the adjacent work area, open the stained ceiling at the junction and photograph the cavity side. Where growth is confirmed, remediate the area as Condition 3 under the containment, PPE and removal procedures in Sections 4 to 6. Where it is not, clean and document the area, and remove material only where it is wet or damaged. The controls specified for this area are precautionary pending the investigation.

3. Moisture source and its correction

Name the source, what has been corrected and on what record, what remains open, who corrects it (by type of contractor), and that it is corrected before remediation starts. Then say how the correction will be confirmed at the end: what is re-tested, under what operating condition, by whom. New York's plan carries the moisture source and the type of contractor who would remedy it "when possible" (NY Labor Law §945). The EPA is plain that mold returns if the moisture problem is not corrected (EPA, A Brief Guide to Mold, Moisture and Your Home).

Source: overflow of the attic air handler's secondary condensate pan. The primary drain was cleared on [date] ([invoice no.]). The secondary pan drain stub remains capped and no float shutoff is installed. Correction: a licensed HVAC contractor terminates the secondary drain and installs a float shutoff before remediation begins, documented by invoice. Verification at clearance: the system is run through a full cooling cycle; the pan must hold no standing water and the shutoff must operate when tested.

4. Containment and negative air

Specify the containment per area and say why that level, and not a lesser one. The EPA scales containment to the size of the contaminated area: limited containment (a single layer of polyethylene with a slit-and-flap entry) for moderate areas, and full containment (double barriers with a decontamination chamber) for larger or higher-risk work (EPA, Mold Remediation in Schools and Commercial Buildings). Containment runs with HEPA-filtered negative air, so any leak draws air into the work area rather than out of it. The setup itself is described in containment and negative air.

Attic and Bedroom 3: full containment. 6-mil polyethylene, floor to ceiling, seams taped; decontamination chamber at each entry; critical barriers over HVAC supply and return registers in or next to the work area; HVAC serving the area shut down or isolated. HEPA-filtered negative air machines exhausting outdoors maintain a pressure differential of [value set by the assessor] relative to adjacent spaces, verified by manometer and logged at the start of each shift and after any breach. Justification: confirmed growth on structural and insulation materials across two areas, with removal that will disturb it directly above occupied rooms. Containment stays in place until written clearance is issued.

5. Personal protective equipment

Scale PPE to the disturbance the task creates and keep it consistent with the containment you specified: a protocol that calls for full containment and an N95 contradicts itself (see HEPA and PPE for mold work). The EPA treats an N95 as suitable for small areas and calls for more protective respirators as the area and the disturbance grow (EPA, Mold Remediation in Schools and Commercial Buildings); an N95 only protects when it seals to the face (NIOSH, Respirator Guidance). Name gloves, eye protection and coveralls as the work requires (OSHA, Mold Hazards and Controls). Use the same respirator in this section and in every procedure step that names one. Respirator selection, fit and medical clearance for the workers sit with the remediation contractor as their employer. In New York the PPE element reads "to be supplied by licensed remediators for use by licensed abaters" (NY Labor Law §945).

Inside containment, all removal and cleaning: half-face air-purifying respirator with P100 particulate cartridges [or full-face]; disposable coveralls with hood and boot covers; nitrile gloves; eye protection where a half-face respirator is worn. Waste handling outside the work area: N95 respirator, gloves.

6. Removal and cleaning methods by material

Methods per type of remediation per area, in imperative steps a crew can follow, with a measurable boundary for every cut. Porous materials with growth (gypsum board, insulation, carpet and pad, ceiling tile) are removed, not treated (EPA, Mold Remediation in Schools and Commercial Buildings); see why dry-looking drywall comes out. Structural wood and other semi-porous materials are generally cleaned in place where sound and replaced where weakened or where cleaning cannot remove the growth. Non-porous surfaces are HEPA vacuumed and damp wiped. If an antimicrobial is used, it is an EPA-registered product applied per its label and never a substitute for removal (see bleach vs antimicrobial). Do not apply coatings or encapsulants before clearance. If materials of unknown composition that could contain asbestos or lead paint will be disturbed, they are tested and handled under those programs before demolition.

Bedroom 3, west wall.

1. Photograph the wall and record pin readings on the bottom plate before disturbing anything.
2. Score and remove gypsum board, both faces, from the floor to [24 in.] above the floor over the full wall length, extending [distance] beyond any growth found above that line.
3. Remove batt insulation and baseboard. Double-bag all debris in 6-mil polyethylene inside containment, seal, wipe the bag exterior, and remove through the decontamination chamber.
4. HEPA vacuum the exposed studs and bottom plate, then clean them [by wire brushing or sanding] until no growth remains visible. Replace any member that is structurally weakened.
5. Record the bag count and the disposal facility.

7. HEPA cleaning

HEPA filtration captures at least 99.97 percent of particles at 0.3 microns (NIOSH, HEPA Filtration Guidance), which is why HEPA vacuums, not shop vacuums, are used for every cleaning step. Specify the final cleaning sequence and what it covers, including any Condition 2 surfaces where settled material from the work area may have landed.

After removal and drying are complete, HEPA vacuum all surfaces inside containment from top to bottom, damp wipe, and HEPA vacuum again, including the polyethylene, the decontamination chamber and the egress path. Notify the assessor when final cleaning is complete; do not remove containment.

8. Drying targets

Two numbers, kept apart. The dry standard is a reference reading on unaffected material of the same kind in the same structure, taken with the same instrument. The drying goal is the target retained materials must reach before clearance sampling is scheduled, derived from the dry standard plus a stated tolerance, so it is never the same number. IICRC S500 describes the comparative method and publishes no fixed percentage to substitute for it (IICRC, S500). ASTM D7438 covers calibration and use of hand-held meters on wood (ASTM D7438).

Dry standard: [9.8% MC], pin meter, unaffected rafter tie in the attic, [date]. Drying goal: [15% MC] on all retained framing and decking (dry standard plus a [5]-point tolerance set by the assessor), measured at [three] points per member and logged before clearance is requested.

9. Clearance criteria and post-remediation verification

Write the finish line before the work starts. State the visual criterion, the moisture criterion, the air or surface sampling method and criteria if sampling is part of clearance, that verification happens while containment is still in place, how air filtration is handled before samples are collected, and how the moisture correction is confirmed. An air criterion such as "at or below the same-day outdoor control, with no indicator genus elevated indoors" is a criterion the assessor sets for this project; no standard publishes a spore count or ratio, and the protocol should label it as the assessor's. Verification is performed by an assessor independent of the remediation contractor (see assessor vs remediator).

Visual: all scheduled materials removed; no visible growth, dust or debris in the work areas. Moisture: retained materials at or below the drying goal in Section 8. Air: one spore-trap sample in each remediated area and a same-day outdoor control; project clearance criterion (set by the assessor): indoor at or below outdoor in total and by genus, with Chaetomium and Stachybotrys not detected or at or below outdoor. Conditions for sampling: containment in place; negative air machines shut down and the area left sealed for [settling period] before collection; a sample collected with filtration running is void. Source: confirmed as in Section 3.

Running filtration during collection scrubs the air being sampled, which is why the shutdown and settling period belong in writing. The pass/fail logic and what each state requires of the clearance document are on the post-remediation clearance criteria page; sampling strategy is in post-remediation verification sampling.

10. Occupant considerations

Say whether the building is occupied, how and when occupants are notified, where notices are posted, which areas are off limits and until when, and how HVAC is handled. New York requires occupant notification for occupied buildings, plus recommendations for notice and posting sized to the project's "size, duration and points of entry" (NY Labor Law §945). Keep this section about the work, not about health outcomes.

The property is [owner-occupied]. Notify the occupants in writing at least [24 hours] before work starts, with the areas under containment and the expected duration. Post notices at each containment entry and at the second-floor hallway entrance stating that the area is a restricted work zone until clearance is issued. Occupants do not enter any containment. Occupants with asthma, immune compromise or other sensitivities may wish to discuss temporary relocation with their physician; this is a precaution, not a medical finding.

11. Standards referenced, limitations and signature

List the standards by name and what each was used for, the protocol's limitations (it is based on conditions documented on the assessment date; conditions found during the work that differ are reported to the assessor before the scope changes), and the assessor's name, license or credential, signature and the date issued. In the District of Columbia every issued protocol carries the date it was issued and all indoor mold assessment professionals' names, license numbers and, if applicable, business name and addresses (20 DCMR §3204.6(d)).

Texas, New York and the District of Columbia

Three jurisdictions put protocol contents into rule, and the template above is organized to carry them. Other licensing states regulate who may do the work rather than what the protocol says; Florida's assessor develops a remediation protocol but the state prescribes nothing about its content.

Texas adds four clearance items the protocol must pre-specify under 16 TAC §78.100(i): at least one nationally recognized analytical method for use within each remediated area; the criteria to be used for evaluating analytical results; that post-remediation assessment shall be conducted while walk-in containment is in place; and the procedures to be used in determining whether the underlying cause has been remediated. At clearance the consultant may use "only the analytical methods and the criteria for evaluating analytical results that were specified in the remediation protocol" unless documented circumstances require otherwise (16 TAC §78.140(c)(2)), so Section 9 is drafted once and drafted carefully. Full detail: Texas mold assessment report requirements and Texas licensing.

New York places the plan on the assessment licensee, who gives it to the client before remediation begins; containment is permissive, not a required element. Full detail: New York mold assessment requirements and New York licensing.

The District of Columbia requires the assessment to produce a written remediation protocol and enumerates its contents in its rules; see District of Columbia for licensing and the post-remediation clearance criteria page for the District's verification report.

After the work: the remediation report

People searching for a mold remediation report template usually mean one of two later documents. The remediation contractor's completion record shows what was actually done against this protocol: materials and quantities removed, containment and pressure logs, moisture logs, waste records, and before-and-after photographs. In Texas the contractor provides the property owner with before-and-after photographs within ten calendar days of the project stop-date and provides the Certificate of Mold Damage Remediation within the same ten days; the assessment consultant, not the remediator, signs the Certificate's top section (16 TAC §78.150). The assessor's document is the clearance report, which has its own template: mold clearance report template. The assessment that precedes all of this is in the mold inspection report template.

How MoldMind writes the protocol

MoldMind generates the remediation protocol from the same job as the assessment, so each area keeps the condition the assessment assigned, and an area left undetermined is scoped with an investigative step instead of a guessed condition. The PPE section and the procedure steps name the same equipment, the drying goal is derived from the recorded dry standard and labelled as the assessor's, and air criteria are labelled as project criteria rather than attributed to a standard. In New York the plan carries the eight §945 elements; in Texas the six §78.100(e) elements with the §78.100(i) clearance items. A compliance panel lists the elements the jurisdiction calls for and flags the ones it cannot find, a checklist that catches omissions, not a compliance guarantee. The inspector reviews and approves the protocol before it goes to the contractor. See the sample report.
