What insurance companies cover mold damage?
Short answer. Most home insurers treat mold the same basic way: they exclude it, then cover mold that results from a sudden, covered water loss up to a sublimit. The real differences between companies are in the policy form, the size of the mold limit, and whether you can buy an endorsement for more coverage, so compare those terms rather than looking for a company that covers all mold.
What to compare between insurers
- The mold sublimit: the dollar cap for mold, and whether it applies per loss or per policy year.
- What the limit includes: cleanup only, or also testing, tear-out and rebuild.
- Endorsements: whether you can buy higher mold limits, and the cost.
- Water coverage details: how the policy handles seepage, water backup and sudden discharge, since mold coverage depends on the water coverage.
- Roof terms: because many mold claims start with roof leaks, how the roof is valued and whether storm damage is clearly covered matters too.
Questions to ask an agent
- What is the mold limit on this policy, in dollars?
- Does it cover mold caused by a storm-damaged roof?
- Is there an endorsement to increase it?
- What does the policy say about repeated seepage?
No policy covers every mold problem
Mold from humidity, condensation, poor ventilation, long-term leaks or neglected maintenance is excluded by standard homeowners policies regardless of the company. Separate environmental policies exist for some property types, but they are uncommon for homes.
Prevention beats coverage
Keep the roof sound, fix leaks quickly and dry wet areas within 24 to 48 hours. See interior water damage coverage and wear and tear vs storm damage.
