| Interior access | Pets, children, allergies, and tenant access can change preparation and timing. | What prep steps, product category, and re-entry window apply? |
| Warranty limits | Some warranties exclude sanitation issues, structural entry points, or heavy infestations. | What conditions would void the service guarantee? |
