Frequently Asked Questions

What's covered?

Sudden and accidental water (pipe burst, appliance failure). NOT slow leaks (mold buildup from years of dripping is excluded). NOT outside flooding (separate flood policy required).

Sewer backup?

Often excluded by default or sublimited to $5-25k. Rider to add full coverage costs 5-10% of premium. Worth it in older neighborhoods with aging sewer infrastructure.

Mold?

Usually sublimited or excluded. $5-10k typical sublimit. Major mold claims often not covered. Be cautious about water damage history in any acquired property.

How do insurance carriers view this?

Insurance carriers underwrite per-peril and often stack deductibles — named storm, wind, hail, flood, and standard can all apply separately on a single event. Confirm with your broker which deductibles actually apply to your policy and stress-test liquidity against the highest applicable deductible. Endorsements and riders can modify base terms; read declarations carefully and keep a written summary on file for claim time.
