A home warranty, or home protection plan, is a service contract, normally for one year, which protects homeowners against the cost of unexpected repairs or replacement on their major systems and appliances that break down due to normal wear and tear. A negotiable contract between the buyers and sellers which do not overlap or replace homeowner's insurance policy, this type of warranty can save the new homeowner lots of headaches, as well as put seller's fears to rest. The warranty covers mechanical breakdowns, while insurance typically repairs the related damage, for example: if a hot water heater burst and destroyed a wall in your home, the warranty would repair the water heater and your insurance would pay to fix the wall.
