How it helps
Use it for a focused task
This guide walks you through the most common ways wildfire smoke gets inside a house. It ranks leak paths by how much smoke typically enters, gives you low-cost fixes using materials most homes already have, and provides a printable room-by-room checklist you can save in your browser and return to each season.
Start with the leak path ranking to understand where to focus. Then work through the room-by-room checklist, marking each item as sealed, skipped, or not applicable.
Use the material alternatives section when you don't have weatherstripping or tape on hand. When done, print or save your checklist.
