How to Compare Dry Ice Cleaning Quotes

To compare dry ice cleaning quotes, give each contractor the same description of the work and ask them to identify what is included. A proposal total is useful only alongside the assets, surface condition, access, working time, and acceptance criteria it covers.

Give every bidder the same project information

Prepare an asset list or clearly marked vehicle areas, overall photographs, close-ups of the deposits, location, and available work window. State the result you need and the materials that must remain. Flag unknown coatings, restricted access, or previous repairs instead of leaving the contractor to assume ordinary conditions.

For machinery, name the surfaces and production constraints. For automotive work, distinguish the undercarriage from the engine bay. For marine work, include yard or marina access arrangements. Link the request to one defined scope rather than a broad instruction to clean everything.

Compare the basis of the price

Ask whether the proposal is a fixed price for defined work, time and materials, or a booked crew period. These approaches need different checks. A daily rate needs an explanation of the day; a project price needs an explanation of the project.

Quote basis	What to clarify
Fixed project price	The included surfaces, result, assumptions, exclusions, and procedure for changed conditions.
Hourly, daily, or shift rate	Crew size, minimum booking, working-time definition, materials, and any limit on the estimate.
Time and materials	Rates, material basis, records provided, and approval before exceeding an agreed allowance.
Area-based price	How area is measured and which geometry, access, deposit, and surface conditions the rate assumes.

Check six scope items side by side

Scope item	Question to ask
People and working time	How many people attend? Does booked time include setup, moving, replenishment, collection, and inspection?
Dry ice and compressed air	Who supplies them? What allowance, delivery, fuel, air treatment, or additional material charge applies?
Preparation and access	Who handles isolation, guards, panels, lift access, protection, and reassembly?
Test and acceptance	What is the test scope, who reviews it, and what result defines completion?
Collection and disposal	Which containment, equipment, labor, waste handling, and surrounding-area cleanup are included?
Changes and delays	Who approves added work, standby, travel changes, or costs from a moved booking?

Record any answer that remains open. If one proposal includes a compressor and another expects suitable site air, obtain the missing information before comparing their totals. The same applies to lift arrangements, material allowances, and cleanup.

Agree on testing and the limits of the method

Where the deposit or surface is uncertain, ask whether a representative test should precede the final scope. Define the test area, inspection, fee if any, and whether any test charge is credited toward later work. Do not assume a free demonstration or a credit unless it is in the proposal.

Cold Jet’s technical FAQ describes limits for strongly bonded coatings and deeply adhered oxidation. If the requirement involves coating removal or a particular surface profile, ask the contractor to identify the proposed method and any abrasive addition explicitly.

Separate the contractor’s price from your own costs

Add your team’s preparation, supervision, access, and return-to-service work to the internal project comparison. Identify any outside lift, disposal, or specialist work that sits beyond the contractor’s scope. Keep those figures separate so you can see who is responsible for each cost.

If you are comparing dry ice with an existing process, use our total job cost guide. It separates combined labor hours from elapsed downtime and asks whether recovered production time has usable value.

Put approvals and completion in writing

Name the person who can authorize changes. Request a pause-and-review process if deposits, access, or surface condition differ from the information supplied. Agree how completed areas, exclusions, remaining material, and cleanup will be recorded at handover.

For time-based work, ask what progress and time records you will receive. For a fixed scope, ask how the result will be inspected. In both cases, make sure completion means the same thing to the owner and the contractor.

Prepare a scope for your quote

Review the pricing guide and the relevant machinery, automotive, or marine service page. Then request a quote with the surface, deposit, location, and timing. Photos and supporting scope details can follow.
