Insurance Restoration PM's Deep Guide to Dry Ice Cleaning

This guide is written for one specific reader: the insurance loss adjuster, restoration project manager, IICRC-certified hygienist, or restoration build owner who’s responsible for closing claims and managing scope. We’ll cover what dry ice cleaning is in detail, when it makes sense in restoration workflows, what documentation we produce, and what the real claim economics look like across fire, mold and water-damage scenarios.

If you’ve used the method before, this is the technical-and-commercial backbone you can show to a sceptical adjuster, hygienist or insurer. If you haven’t, this is the case for adopting it as a documented step in your restoration workflow.

Why this method matters in restoration

Restoration work runs on three constraints: timeline, scope, and documentation.

Timeline pressure. Tenants want their property back. Customers want operations resumed. Every day a building is out of service has direct cost. Cleaning steps that are slow, water-introducing, or rinse-required eat into the build schedule.

Scope discipline. The difference between a $40K claim and a $400K claim is whether materials and equipment can be cleaned or replaced. Aggressive cleaning methods — sandblasting, acid wash, chemical strippers — drive replacement decisions because they damage substrates that could otherwise be saved.

Documentation requirements. Adjusters need photo evidence and process records. Hygienists need clearance-friendly procedure documentation. Builders need tender-style proposals and per-claim records. The cleaning method either supports those documentation flows or makes them harder.

Dry ice cleaning is a category of cleaning that:

• Doesn’t introduce moisture into structures that have already been compromised
• Doesn’t damage substrates beyond the contamination layer
• Produces a physical-removal outcome aligned with IICRC frameworks
• Generates structured documentation as part of the standard process

Used correctly, it shifts the default scope decision from “replace” to “save” on a measurable percentage of restoration claims.

IICRC framework alignment

We don’t claim IICRC certification per se — but our procedures align with the relevant standards across all three claim types we routinely work in.

S500 — Water damage. Dry ice supports equipment recovery, post-drying material cleaning, and the removal of biological growth on water-affected substrates. We work after structural drying is complete and at moisture content acceptable to the hygienist. We sequence with the drying contractor and the hygienist’s clearance schedule.

S520 — Mold remediation. Dry ice is a primary physical-removal step for mold from timber, masonry and HVAC. The S520 framework emphasises physical removal over chemical inactivation; dry ice does exactly that. HEPA-filtered negative pressure containment, hygienist clearance protocol, and post-clean antimicrobial step where required.

S540 — Fire and smoke damage. Dry ice removes soot from timber framing, masonry, contents and equipment without sanding dust or chemical residue. Particularly valuable for saving structurally-sound timber that would otherwise be replaced. Smoke odour treatment (ozone or hydroxyl) follows physical removal as a separate step.

For each framework, we work alongside IICRC-certified hygienists, restoration builders and (where applicable) directly with the loss adjuster. We provide procedure documentation suitable for hygienist review and per-zone records suitable for adjuster sign-off.

The documentation pack

This is the operational backbone. Every restoration job we run produces:

Per-zone photo log. Pre-clean, during-clean, post-clean for every grid square (typically 1m × 1m for residential, 2m × 2m for commercial). Photos timestamped, geotagged to the building, and labelled to the zone naming convention.

Area map. Building floorplan with zones marked, work sequence, and (for mold work) sample collection locations. Annotated with hygienist’s pre-clean readings and post-clean targets.

Procedure record. Equipment used (rig serial, pellet supplier, pellet size), pressure setting per zone, dwell time per surface, atmospheric monitoring readings, operator on-site, hours worked, dry ice consumption.

Surface readings. Where applicable — surface moisture readings (for S500 work), ATP swabbing results (where contamination is biological), insulation resistance (for S500 equipment recovery). All time-stamped to the photo log.

Operator log. Crew on-site, hours worked, dry ice consumed, any deviations from procedure with reason.

Sign-off summary. Adjuster-friendly one-pager with key facts, photo highlights, surface readings, and certification statements. Signed by the on-site lead.

The pack is delivered as a structured PDF + photo bundle within 48 hours of job close-out. For high-value or complex claims, we can deliver the same content as an XML feed for direct ingestion into your claims management platform — ask if you want this.

Sub-trade structure

Most of our insurance restoration work is sub-trade to restoration builders. Standard structure:

Insurance certificates. Public liability $20m, with sub-trade endorsement available. Workers compensation in all states we operate. Professional indemnity. Issued direct to your broker.

Engagement. Per-claim quote against scope-of-works document, or framework agreement for high-volume builders with rate-card pricing.

Billing. Net-30 monthly billing for active builder partners. Itemised invoice per claim. Match-to-scope reconciliation provided.

Communication. WhatsApp / Slack channels for active jobs (your preference). Photo log uploaded to your QA platform if you have one. Customer-facing communication handled by your build (we don’t reach out to your customer directly).

Scheduling. Slot into your build sequence. We work after drying contractor; before re-fit trades. Specific zone scheduling agreed with your build lead.

This is built on long-term builder partnerships rather than one-off transactions. The structure assumes ongoing volume and reciprocal predictability.

What we don’t replace

Worth being clear on this — dry ice cleaning is one step in a restoration. It doesn’t replace:

• Structural drying — that comes first. We work after drying contractor handover.
• Hygienist sampling and clearance — runs in parallel; we coordinate.
• Specialist consultation — for heritage or high-value-contents work, conservator or specialist input still needed.
• Re-fit trades — carpentry, painting, electrical, plumbing all happen after our work.
• Smoke odour treatment — for deeply-absorbed odour. Ozone or hydroxyl is a separate step.
• Decontamination of biohazard materials — outside our scope. Specialist Cat-3 / hazmat contractors required.

We integrate; we don’t substitute.

Claim economics — real numbers

A few real comparisons from claims we’ve worked on:

Residential mold (timber framing). 80m² affected zone in a 1990s timber-frame house, post-flood mold growth on bottom plates and framing. Replacement scope (existing scope-of-works): $52,000 (timber, labour, plaster reinstate, paint). Dry ice clean + hygienist clearance + retained timber: $11,200 cleaning + $4,800 minor reinstate. Savings: $36,000.

Commercial fire (timber-framed warehouse). 1,200m² timber-framed warehouse with localised flame damage and heavy smoke deposit throughout. Original scope: full structural replacement ($380,000+). Dry ice clean + targeted replacement of charred zones only: $42,000 cleaning + $68,000 partial replacement. Savings: $270,000+.

Industrial water damage (motor recovery). 4× 75kW motors flooded in a manufacturing event. Replacement scope: $96,000 + 12-week lead time. Dry ice clean + IR test + return to service: $8,400 cleaning, $0 motor replacement, $0 manufacturing downtime extension beyond drying period. Savings: ~$96,000 + 10 weeks of avoided downtime.

Heritage building post-fire (decorative plaster + masonry). 600m² affected area in a heritage council building. Original scope (heritage authority requirement: replacement-by-replication): $480,000+. Dry ice clean + heritage authority-coordinated documentation: $58,000 cleaning + $0 replacement. Savings: $400,000+.

These are not unusual outcomes. Per-claim savings in the $20K-$200K+ range are routine. Across an active builder partnership we run, average savings per claim where dry ice is the primary cleaning step land $45-$80K.

The cleaning cost is real but small. The replacement cost it avoids is large. Your scope-of-works decisions become better economics when cleaning is on the menu.

Mobilisation timelines

Declared events. 24-72 hours in metro areas; 3-5 days in regional. We staff for declared-event response. Multiple zones in parallel for large-loss work.

Standard restoration. 5-10 business days for scope agreement and start. Faster for active builder partners with rate-card pricing.

Multi-week campaigns. Per-week scheduling agreed with the build lead. Crews dedicated for the duration.

Out-of-hours / weekend. Available with appropriate prior notice. Particularly common for commercial restoration where business hours work isn’t possible.

When NOT to use dry ice cleaning

A few honest “don’t” answers:

• Charred / structurally compromised timber. Replace, don’t clean.
• Cat-3 water damage (sewage / heavily contaminated). Specialist hazmat contractor.
• Severely water-saturated organics. Dry first; clean second.
• Materials with deeply-absorbed odour beyond surface soot. Ozone/hydroxyl follow-up needed.
• Asbestos-containing materials. Specialist asbestos contractor.
• Electrical equipment that’s failed catastrophically. Replace, don’t clean.

Over-claiming the method’s reach is bad for everyone — it leads to disappointment, callback work, and reputation damage. We say “no” when no is the right answer.

Final thoughts

Dry ice cleaning has shifted the default scope decision on hundreds of restoration claims we’ve worked on. The cases where “replace” was the only option used to outnumber “clean” — now it’s the other way around for the claim types we work in. The change in scope decisions is enabled by:

• Method that physically removes contamination without damaging substrate
• Documentation that satisfies adjuster, hygienist and builder
• Sub-trade structure that fits existing restoration build workflows
• Cost that’s small relative to the replacement it avoids

If you’re a restoration builder evaluating us as a sub-trade, the 60-second quote tool is the right starting point. If you’re an adjuster considering us for panel inclusion, download the Insurance Adjuster’s Guide and we’ll set up a follow-up call to walk through the operational fit.
