Scope and sequence
Ask for the answers in writing so you can compare them later.
- Which rooms, surfaces and soft items does the scope include, and which are excluded?
- What is the order of work, and why does it start there?
- How will you determine whether carpet pad, filters or duct sections should be replaced?
- What will be cleaned versus sealed, and what has to be dry before sealing?
- What is your plan if you find moisture, mold or electrical hazards?
Safety and materials
- Which products and equipment will be used, and can I see the safety data sheets?
- How are occupants and belongings protected during treatment?
- Will smoke detectors, electronics or sensitive materials be covered or moved?
- How long should the space stay empty, and who decides it is safe to return?

How to read the answers
A useful answer is specific. It names rooms, materials and steps and explains why. A vague answer, such as that everything will be treated, may be hard to evaluate. If a provider recommends replacing a large item, ask what you would see or smell if it were cleaned instead. If a provider recommends a one-visit fix, ask what will be checked afterward.
Ask how a provider documents condition before and after. Photos, notes and readings give you a record for a landlord, buyer or insurer. Check licensing and registration requirements with the appropriate Colorado or Denver agencies yourself, since requirements differ by trade and change over time, and ask about any insurance details in writing.
Finally, take your time. A fair provider should be able to explain the plan without pressure, and a short delay to compare options rarely makes an odor problem worse.
Common questions
- Should I get more than one opinion?
- Often yes, especially for larger scopes. Compare written scopes rather than just totals.
- What if they recommend ozone?
- Use the ozone and fogging guide to ask about occupant safety, materials and what is done first.
- Do I have to ask every question?
- No. Pick the ones that matter most for your situation and ask for the answers in writing so they can be compared.
- What if someone refuses to answer?
- That is useful information in itself. Consider asking another provider for a written scope.
