Will Homeowners Insurance Cover Cracked Chimney Liner?
Only if the crack came from a covered peril like a chimney fire or lightning strike, not from age or normal wear.

If the chimney liner cracked on its own
A chimney liner that cracks from years of heat cycling, moisture, or old mortar breaking down is treated as wear and tear, and that's excluded on every standard policy regardless of who insures the house. If a chimney fire caused the crack, or lightning hit the chimney, that's a covered peril and the claim should go through like any other covered loss. This matters more right now if you're working from a non-renewal letter, because a chimney problem found during an inspection, even one that was never claimed, can be part of why an insurer flagged the house. Check the inspection report or the adjuster's notes if there was a claim. If the liner's age or condition was the real reason behind the letter, a repair or a newer liner can make the house easier to place with another insurer.
A damaged chimney liner still needs a policy behind it
If the liner's condition contributed to your non-renewal, other insurers will ask about it too. Comparing quotes now shows which ones still price the house fairly before your current coverage runs out.
What happens if the inspection flags the chimney but it never caused damage
Insurers sometimes order a four-point or full home inspection before a renewal, and a chimney liner showing cracks or a deteriorating flue tile can get written up even if nothing has happened yet. That's not a claim, and it's not damage from a covered peril, so there's nothing to file. But it can still show up as a reason for non-renewal, because insurers treat it as a future liability rather than a past loss. The letter itself should say what the inspection found. If it doesn't name the chimney specifically, ask for the inspection report or the underwriter's notes so you know exactly what triggered the decision.
A cracked liner found this way is a repair issue, not an insurance issue. Chimney sweeps and masons can reline a flue or replace damaged tiles, and many insurers want to see that work documented before they'll offer a new policy. Keep the invoice and any inspection report showing the repair was done. Some companies will ask for a follow-up inspection to confirm the chimney passed before binding coverage.
If the house has a wood-burning fireplace or insert, expect chimney condition to come up again at the next renewal even after repairs, since insurers that write older homes tend to inspect chimneys on a cycle rather than once. Keeping records of when the liner was last inspected or relined helps if a future insurer asks, and it can also keep the house from getting flagged again over the same issue.
Not every insurer weighs chimney condition the same way. Some decline any house with an older unlined chimney outright, others accept it with proof of a recent sweep and inspection, and some don't ask at all if the fireplace is capped and unused. That range is exactly why shopping around matters here. A house that got dropped for a chimney issue with one insurer isn't automatically a hard case everywhere.
Does the type of chimney matter for coverage or for getting re-insured
A masonry chimney with a clay liner, a metal chimney with a factory-built liner, and an unlined older chimney are not treated the same by insurers. A cracked liner on any of them is still wear and tear rather than a covered loss. Unlined chimneys draw the most scrutiny because there's no barrier between the heat and the masonry itself, and a lot of insurers won't write a house that still has one in active use. If the inspection report lists the chimney as unlined, that detail alone may matter more to an underwriter than the fact that it has a crack.
Metal liners and clay tile liners fail in different ways and get judged differently too. A metal liner that's rusted through or separated at the seams often gets flagged as a fire risk regardless of the house's age. A clay liner with a few cracked tiles in an otherwise sound chimney might be seen as routine deterioration on an older home. The inspection report or the adjuster's notes, if there's a claim history involved, usually say which kind of liner is installed and what shape it's in. That's worth knowing before calling around for quotes, since it changes which insurers are worth asking.
Whether the fireplace is actually used changes the calculation as well. A capped, disconnected, or decorative-only fireplace with a cracked liner is a much smaller concern to most insurers than one that's lit every winter, because the liner's job is to safely vent active combustion. Some insurers will overlook liner condition entirely if the chimney is permanently capped and documented as not in use. If that's the case on this house, it's worth saying so upfront when getting quotes, since it may open up options that a plain reading of the inspection report wouldn't suggest.
None of this changes what triggered the non-renewal letter, but it does explain why one insurer's decision isn't necessarily shared by the next one. A house with an old unlined chimney that's still in daily use is a harder sell across the board. The same house with a relined flue, a recent sweep, or a capped and unused fireplace looks like a different risk on paper, even to insurers that ask the exact same inspection questions.
