What Does Dry Ice Blasting Cost?
Dry ice blasting projects with Service-Tech Corporation start at a $2,000 minimum engagement. That minimum reflects what it takes to put a trained crew, a blasting rig, an industrial air compressor, and fresh CO2 pellets on your floor for a productive shift — dry ice blasting is a crew-and-equipment service, not a per-square-foot commodity.
Above the minimum, pricing is scoped per project after a site assessment. Across the wider market, contractors typically frame dry ice blasting in hourly or day-rate terms with per-project variables layered on top.
Because scope varies so widely — a single electrical cabinet versus a full production line — a firm number requires a walkthrough. Every Service-Tech estimate is free, and travel is factored into the quote rather than billed as a surcharge.
The Six Cost Drivers Inside Every Quote
Two facilities can request "dry ice blasting" and receive very different quotes. These are the variables that actually move the number:
- Contaminant type. Carbonized grease, cured adhesive, paint, mold, and production residue each release at different rates. Softer, thicker buildup can slow a crew more than a harder, thinner layer.
- Substrate. Delicate surfaces (wiring, gaskets, historic wood) require lower pellet aggression and more passes than steel or concrete.
- Access. Ground-level equipment blasts faster than ceiling-level ductwork, elevated structural steel, or interior tank surfaces that require confined-space procedures.
- Containment. Blasting sends dislodged contaminant airborne. Food plants, mold jobs, and occupied facilities may need poly containment and HEPA-filtered vacuum recovery, which adds setup hours.
- Hours of operation. Work restricted to sanitation windows, overnight shifts, or planned shutdowns compresses the schedule and shapes crew planning.
- Pellet consumption. CO2 pellets are consumed continuously during blasting; heavier buildup means more pellets per square foot.
How a Dry Ice Blasting Quote Is Built
A credible dry ice blasting quote has a predictable anatomy. When you compare bids, look for these line items rather than a single lump number:
| Quote line item | What it covers | What inflates it |
|---|---|---|
| Mobilization | Crew travel, rig transport, setup and teardown | Distance, rigging, elevated or confined access |
| Labor | Blast technicians plus a lead | Contaminant thickness, substrate sensitivity |
| Equipment | Blasting unit, industrial compressor, hoses, nozzles | Specialty nozzles, aerial lifts |
| CO2 pellets | Media consumed during blasting | Buildup volume, job duration |
| Containment and recovery | Poly, negative air, HEPA vacuuming of debris | Food-grade or mold-remediation requirements |
| Downtime coordination | Off-shift, weekend, or shutdown scheduling | Compressed work windows |
Service-Tech scopes each of these during the free site assessment, so the quote you sign is the invoice you receive.
The Total-Cost Comparison Competitors Leave Out
Ranking cost pages compare hourly rates. Facility managers should compare total cost of cleaning — and that is where dry ice blasting frequently wins despite a higher headline rate, because CO2 pellets sublimate on contact and leave no spent media behind:
| Cost category | Dry ice blasting | Abrasive media blasting | Pressure washing |
|---|---|---|---|
| Secondary waste stream | None — pellets sublimate | Tons of spent media to collect and dispose | Contaminated wastewater to manage |
| Disposal line item | Only the removed contaminant itself | Media + contaminant disposal | Wastewater capture/treatment where required |
| Drying downtime | None — completely dry process | None, but grit cleanup extends re-entry | Hours to days before equipment restart |
| Disassembly labor | Often cleans equipment in place | Frequently requires teardown or masking | Limited around electrical components |
When you add disposal, drying, and disassembly to the competing methods, the dry process is often the lower total number — which is why the honest comparison is project-to-project, not rate-to-rate.
When Dry Ice Blasting Is the Cheaper Option
Three scenarios where the $2,000 minimum routinely beats the alternatives on total cost:
Electrical and control equipment.
CO2 is non-conductive and moisture-free, so switchgear and panels can be cleaned without the drying, dielectric testing, and re-energization delays a wet method forces.
Food production environments.
No water, no chemical residue, and no grit means production can resume as soon as removed debris is vacuumed — a decisive advantage inside a short sanitation window. Food plant sanitation projects with Service-Tech carry a $1,375 minimum.
Fire and smoke damage restoration.
Dry ice removes char and smoke residue from structural surfaces without soaking materials that water would push toward demolition.
There's also a bundling advantage: Service-Tech crews already mobilize across Ohio, Florida, and Arkansas for commercial air duct cleaning (from $1,375) and cooling tower cleaning ($1,375 minimum). Adding a blast scope to a crew that is already on your site spreads mobilization cost across both jobs.

Which Steps Actually Consume the Hours
Blast time is rarely the biggest number on a dry ice quote.
- Ventilation and monitoring setup. Sublimated CO2 gas is denser than air and settles low, so any enclosed space needs forced ventilation running to ventilate it continuously and the atmosphere metered before work starts. In a vessel or pit that setup can exceed the blasting itself.
- Masking and containment. Anything that must not be blasted gets masked, and the removed contaminant still has to be caught. The medium leaves as gas; the residue does not.
- De-energising. Panels and switchgear are de-energised, locked out and tagged before cleaning. Coordinating that with production is often the scheduling constraint, not crew availability.
- Pellet consumption. Media is consumed continuously while the trigger is down, so surface area and contaminant hardness drive supply cost directly.
- What you are not paying for. No dry-out wait, no grit to sweep and characterise, and no wash-water to contain — which is where dry ice usually wins the total-cost comparison even when the hourly rate is higher.
Frequently Asked Questions
How Much Does Dry Ice Blasting Cost per Hour?
Most of the market quotes dry ice blasting in hourly or day-rate terms, but the honest answer is that rate alone won't predict your invoice — contaminant, access, containment, and pellet consumption move the total more than the rate does. Service-Tech Corporation prices dry ice blasting per project with a $2,000 minimum engagement, quoted free after a site assessment.
Why Is There a $2,000 Minimum Engagement?
Every blast job requires the same baseline: a trained crew, the blasting rig, an industrial compressor, and fresh CO2 pellets delivered to your site. The minimum covers that mobilization so small projects are priced honestly instead of padded. If your scope is small, bundling it with duct, tower, or other industrial cleaning work on the same mobilization is often the economical path.
Is Dry Ice Blasting More Expensive Than Sandblasting?
The headline rate is often higher, but the total is frequently lower. Sandblasting produces tons of spent media that must be swept, hauled, and disposed of — sometimes as regulated waste when it captures paint or oils. Dry ice sublimates on contact, so you pay to remove only the contaminant itself, and equipment often stays in place instead of being torn down.
Do You Charge Extra for Travel?
No separate surcharge. Service-Tech operates offices across Ohio, Florida, and Arkansas with a 150-mile service radius from every office, and travel is factored into the project quote you approve up front.
What If I Get a Much Cheaper Dry Ice Blasting Quote?
Compare scope, not totals. Ask whether the low bid includes containment and HEPA recovery of dislodged debris, adequate compressor capacity for continuous blasting, and enough pellet volume to finish the job — the common places a lowball quote quietly cuts. A quote built on a real site assessment protects you from change orders later.
