That depends on the nature of the loss. Contact your Insurance Agent and he will be able to advise you on coverage.
I have my contents covered on my home owners policy.
If your garage doors were damaged by a covered peril as defined by your home insurance policy then the door would be covered.
If the motorcycle was inside the garage of the house, most likely it will be covered. Check your policy.
If the garage is attached to your home then it would be covered under Coverage A of your policy. If the damage was caused by a bad storm then more than likely the damage would be covered under your policy. If you have a HO-3 policy then the damage should be covered. Call you agent and ask him/her to review your policy to determine if the damage is covered before you call your insurance company.
They are only covered if they themselves are insured under their own policy.
If you have wind and hail coverage on your policy and the detached garage is a covered structure on that policy then Yes, your policy would cover the damages.
No. It covered under a motorcycle policy.
Any motor vehicle is not covered under the HO policy.
home owners always need to pay their water policy.
No, it is covered under your comprehensive part of the policy. You will have to pay the deductible tho.
The theft of the auto itself would be covered by your auto policy. Damage to your structure caused by burglars would be covered by your homeowner's policy.
This will vary from policy to policy but generally musical instruments are covered. You should check to see if there are any limits on an item's value or any specific clauses in your policy.
