Who Pays for Mold Remediation?
Only if the mold comes from a sudden covered loss, like a burst pipe. Gradual leaks usually aren't covered.

What caused the leak
A pipe that bursts overnight is a sudden loss, and the mold that follows it usually gets covered along with the water damage. A slow drip under a sink that nobody noticed for months is treated as a maintenance problem, and mold from it is not.
How your policy defines it
Your declarations page may list a specific dollar limit for mold remediation, often lower than your dwelling coverage, even when the underlying leak is covered. Some policies exclude mold entirely unless you add it back with an endorsement. Check the policy wording, not just the limit on the summary page.
What the inspection found
If a home inspection before closing turned up existing moisture, past leaks, or visible mold, an insurer will treat that as a known condition, not a future claim. Fixing it before you close protects both your health and your ability to get a clean binder issued.
Your deductible before any payout
Even a covered mold claim tied to a burst pipe only pays out above your deductible. If the remediation and repair come in under that amount, the policy pays nothing, and the cost falls on you the same as an excluded claim would.
A low mold limit can undo the rest of your coverage
Two policies with the same dwelling coverage can set very different mold limits and deductibles. Comparing them before you bind, not after a leak, is how you find out which one actually pays.
What to do if you find mold before closing
If an inspection or a walkthrough turns up mold, don't expect a new policy to pay for cleaning it up. Insurers ask directly about known damage or current conditions when you apply, and mold found before the policy exists is a known condition, not a loss. Disclosing it is not optional. Leaving it off the application can get a future claim denied, or the policy itself canceled once the insurer learns about it later.
The seller's response to the inspection matters more than your insurance search at this point. A seller can pay for remediation before closing, credit you at closing so you handle it after, or refuse. Whichever happens, the mold needs to be dealt with before an insurer will treat your house as insurable in the normal sense. Some carriers will decline to write a policy at all on a house with unresolved mold or moisture damage, which can hold up the binder your lender is waiting for.
If the mold is tied to something structural, like a roof that's been leaking for years or a foundation that lets water in after every rain, fixing the mold without fixing the source means it comes back. An insurer looking at that house later, at renewal or after a claim, will ask what caused it. Getting a moisture or leak source corrected, not just the visible mold removed, is what actually protects the coverage you're trying to put in place.
None of this shows up on a quote. A quote reflects the dwelling value, your deductible, and the coverage options you picked, not what an inspector found last week. The mold question gets resolved separately, between you, the seller, and sometimes a remediation company, before the house is in a condition any insurer wants to take on.
What if the inspection found mold after you already got a quote
A quote you got before the inspection doesn't change once mold turns up. The number was built from the dwelling value, your deductible, and the coverage options you chose. It wasn't built from the condition of the house that week. If the inspection comes back with mold, the quote is still sitting there, but it isn't the thing standing between you and a binder anymore.
What usually happens next is the underwriter asks for more information before issuing a policy at all, not a different price. Some insurers will ask for proof the mold was remediated, a letter from whoever did the work, or photos of the area after repair. Others will decline the house until the underlying cause is fixed and documented, whether that's a roof, a pipe, or grading around the foundation. None of this gets solved by paying more. An insurer that doesn't want the risk won't take it at any price.
Timing against closing gets tight here. If the lender is waiting on a binder and the insurer is waiting on remediation proof, the two deadlines can collide. Getting the remediation done fast, and getting paperwork from whoever did it, matters more at this point than comparing another round of quotes. A second insurer will likely ask for the same proof the first one did.
If one insurer declines the house over mold, that doesn't mean every insurer will. Underwriting guidelines differ, and some are more willing to write a policy once remediation is documented, even if the mold was extensive. This is a reasonable point to compare insurers again, not on price alone but on whether they'll issue a policy on a house with a mold history at all. Some ask about it at every renewal going forward. Others move on once the fix is documented and never bring it up again.
Before you bind
Find the mold remediation limit and deductible in the policy wording, not the summary page, and check whether mold needs its own endorsement. If the inspection found any moisture or mold, get it resolved before you ask for the binder.
