Questions to ask before you approve any odor work

Ask what the proposed work is meant to solve

An odor assessment should start by describing where the smell is strongest, when it changes, and what has already been tried. Ask the professional to explain which observations support the suspected source and what alternatives remain possible. If an answer depends on an unverified assumption about the building, ask how it will be checked. Avoid accepting a neighborhood-level generalization as a diagnosis of an individual home.

For each proposed task, ask which room and material are included, how the source will be stopped, what cleaning method matches the substrate, and what conditions would change the plan. Ask whether a product will be used, where its label and safety information can be reviewed, whether occupants must leave, and how the area will be ventilated. A responsible explanation should discuss limits, not promise that every odor will disappear.

Clarify exclusions and next steps in writing. Will the assessment include plumbing, HVAC, moisture, or only visible surfaces? Who is responsible for diagnosing a system outside the person's scope? What is excluded from cleanup, and how will hidden conditions be handled? No phone number, urgency claim, or assurance of service availability should substitute for verifying the actual operator, qualifications, and written agreement independently.
