How to use these guides
Every guide here is written by June Calloway, our restoration guides editor, from the questions homeowners, tenants and property managers ask us most. They are grouped by situation rather than date, so you can go straight to the one that fits.
Where a guide mentions costs, the figures come from published 2026 cost guides and are planning ranges, not quotes. Where it mentions Los Angeles specifics, like the February 2024 storm or the age of the housing, those come from public sources.
