Home Warranties questions, answered by experts

Reputable home warranty companies don’t have hidden costs, but it is important to understand the structure of your agreement and home warranties in general before signing up for one. The most significant and predictable cost you’ll incur is the monthly price. In addition to that, you’ll have to pay the service fee—an average of $85—every time you need to call in a professional for a repair or replacement. The service fee is usually much less than the repair or replacement would otherwise cost, but it’s worth considering in your total.

The average cost of a home warranty is around $55 per month, but you could pay anywhere from $30 to $125 or more, depending on a few factors. Some of the most significant cost factors include the following:

  • Contract service fee 

  • Items covered by your contract 

  • Coverage caps in your contract

  • Whether or not you can choose your own service technician

  • Home’s location

  • Contract length 

  • Any coverage add-ons

You may be able to negotiate an as-is purchase, but many sellers who list their homes as-is aren’t willing to lower their asking price since they’ve already accounted for the price of repairs. Homes are often listed as-is for a quick sale, so there’s a chance a seller may negotiate in order to make the sale—it never hurts to ask.

Before you replace your windows, check your home warranty. Many home warranties don’t cover windows at all, while some have specific clauses about what they will and will not cover and what might void the warranty. If you have any questions, reach out to your insurance specialist, and never make assumptions.

It’s easy to confuse home warranties with homeowners insurance, but they aren’t the same thing. The key difference is that warranties protect your appliances and systems, but insurance guards your house against disasters like fires and storms. Keep in mind that warranties may not cover repairs if the issue was caused by a DIY job gone wrong.
