Room checklist

Basement checklist

Use this page to create a practical task list for your basement. Record only what you can observe safely. Choose “unknown” when information is missing; uncertainty is a useful next step.

Five things to look at

Choose Observed, Needs follow-up or Unknown for each row. Nothing you choose is sent or saved, and it does not change the full checklist.

  1. Row 1: Record visible water entry, dampness or staining in accessible areas.
  2. Row 2: Note whether stored items obstruct inspection or equipment access.
  3. Row 3: Check whether you have prior radon-test information without interpreting it through this website.
  4. Row 4: Locate instructions for dehumidification or monitoring equipment already present.
  5. Row 5: List unresolved building questions for the responsible professional or property manager.

Nothing is pre-selected. Choose what you can observe safely; skip the rest.

What to do with your notes

Use official radon guidance for testing decisions and the moisture checklist for observations. Do not enter hazardous areas or treat this checklist as a building inspection.
