It depends on several factors
What caused the cracks
What are the ramifications of those cracks.
If the cracks were caused by a covered peril and there is actual damage beyond aesthetics then yes it would be covered
Bear in mind though that all concrete structures will develop cracks. It's a natural occurrence that generally has no effect on usability. So long as the cracks do not adversely effect the structural integrity of the home there is generally no need for repairs as this is a natural and expected occurrence.
If the foundation problems are not covered then it naturally follows that any resulting cracks would also not be covered.
It is not a good idea to cover foundation cracks with gardening. Have a knowledgeable building expert check the foundation crack and repair it. Don't hide it with plants and invite water to leak into your house.
No. Unless the foundation problem happened because of an earthquake or flood (and you have insurance to cover both catastrophic events), then your insurance will not cover something that has degenerated with time.
"Flood Insurance" will cover damage resulting from a Flood. Homeowners Insurance will not.
No.
Settlement cracks and cracks from ground shifting are not covered.
No. Movement of earth is specifically excluded by homeowners insurance. This is the fault of the builder for not compacting the earth properly and providing the proper foundation. Home insurance was not made to cover such.
You'll need to check your policy or contact your insurance agent to find out if you have coverage for ground movement. Most homeowners insurance policies do not provide coverage for damages resulting from ground movement as this normal and expected over the life of a structure.
I had a large crack in my foundation and my homeowner's insurance refused to pay. When such a thing happens, it must be repaired immediately and the person you need to repair it must be an expert in foundation repairs. It cost me $5,800, plus another $1,000 because I choose to call in a structural engineer. I was angry with my insurance company; later learned that most (all?) insurance companies do not pay for cracks in foundations as they are very common.
no
No, that is a maintenance issue. Insurance companies don't pay for maintenance on your house.
No unless the foundation crack was caused by something like an earthquake. Normal wear and tear is not covered.
