One of the most obvious areas of coverage for a homeowner living in Thornhill is water damage. Items such as basement finishes, drain backups, sump pumps, sewer backups, and policy exclusions should all be considered when getting a quote.
Crime, flood, and fire risk explain why individual home prices vary from the median of $1,950 for a standard-profile home, a figure that is lower than the median for Ontario as a whole.
Also check the terms of insurance policies, such as limits on water damage, the size of deductibles and exclusions, and required or recommended precautions.
