Odor Cleanup FAQs

The source may still be present in surfaces, porous materials or contents. Temporary masking can change what is noticed without removing the source. An assessment should consider where the odor is strongest and what materials may be holding it.

Record where and when the odor is noticeable, relevant occupancy or building conditions, the known or suspected source, and previous cleaning or treatments. Keep observations separate from guesses about the cause.

No. Persistent odor work should start with source assessment and appropriate cleaning or removal. Supplemental equipment may support the plan, but it does not replace decisions about materials that continue to hold or release odor.

That depends on the source, extent and condition of the materials. Some can be cleaned; others may require removal or treatment of the underlying assembly. Ask why each material decision is proposed before approving the scope.

Not by itself. Screening instruments measure particular parameters, not every odor or the human experience of smell. Discuss how the result will be assessed under normal building conditions and how remaining concerns will be handled.

A reliable scope depends on the source, affected materials, access and prior treatments. Photos and a description may help start the conversation but cannot establish every condition. Confirm expectations and any written terms after assessment.

Yes. Describe the vacancy or occupancy status, access arrangements and target turnover date. Clarify which source work is included and how completion will be assessed before new finishes or incoming occupants complicate access.
