Will a home warranty refuse a claim for a pre-existing condition?

The regulator page behind this guide does not use the phrase "pre-existing condition"; what it says about exclusions is below. This guide reports what California's Department of Insurance does say about exclusions, required disclosures and denied claims, and says plainly where its page stops.

What CDI says about what a home warranty covers

CDI describes a home warranty as a contract in which the warranty company "promises to repair or replace parts of a home system or certain appliances." It says home warranties "cover wear and tear, deterioration, or defects that existed when you bought or leased your home," and that the specific appliances, systems and components covered "will be stated in the contract."¹ That sentence is CDI's general description of the product. It is not a promise that any given claim will be paid, and the same page goes on to stress exclusions and limits.

What CDI says about exclusions

The page tells buyers it is "especially important to read and understand the 'exclusions' and dollar limits on what the company will pay."¹ It states that "home warranty forms are not standardized."¹ It also says "all home warranties contain dozens of exclusions" and that "many buyers only discover the exclusions, conditions, and limitations that exist in every home warranty when they file a claim and have it denied."¹ CDI lists "unfair claim denials and unreasonably delayed repairs" among the things consumers sometimes complain about.¹ A complaint is a record that someone complained, not a finding that a denial was wrong.

What California law requires a home warranty to say

CDI says California law requires home warranties to state, "in clear and conspicuous terms," the following, among other things:¹

• each of the appliances, systems and components covered;
• "all exclusions and limitations";
• the period the contract stays in effect, the fee, and the renewal terms, if any;
• the services to be performed and the terms and conditions of performance, and the service fee or fees, if any;
• all limitations on performing services, including restrictions on when or where services may be requested or performed;
• a statement that services will be performed on a telephone request without claim forms being filed first; and
• a representation that services will be initiated by or under the direction of the company within 48 hours after a request.

CDI's list includes "all exclusions and limitations." The page does not say what follows if an exclusion is not stated, or how a company must apply one. This is a description of one state's consumer page. Other states regulate home warranties differently; see our state guides.

If a claim is denied

CDI says that "if a home protection company denies your appeal, you may seek assistance from the Department," and gives a phone number (1-800-927-4357), a Getting Help page for chat, and an online Request for Assistance.¹ Our guide on where to turn after a denied home warranty claim covers other routes, and how claims get processed describes the usual sequence.

Questions to bring to your contract

These are our suggestions for reading a contract; they are not taken from the CDI page.

• Does the contract mention pre-existing conditions, prior wear or prior damage anywhere? If so, how does it define the term?
• Does the contract say what proof, inspection or maintenance records the company may ask for when you file a claim?
• Are the exclusions and dollar limits listed in one place, and does the contract say whether they apply to the item you are worried about?
• If a claim is denied, where does the contract say you can appeal, and does it have an arbitration clause? (See arbitration clauses.)

How this connects to our standard and Register

Point 5 of our standard asks whether a pre-existing-condition exclusion is stated plainly before purchase and applied as written. The Register explains how we check home warranty providers against that point and the rest of the standard. This guide is not a verdict on any company and does not predict how any company will treat your claim.

How to verify this yourself

• Read the CDI page itself (reference 1): the sections "What Is a Home Warranty?", "Required Home Warranty Terms" and "What Should I Do If My Claim Is Denied?".
• Read your own contract's list of exclusions and limits before you buy, and ask the seller to point to the exact wording on any item you care about.
• If you are outside California, ask your state consumer protection office (USAGov directory) what your state requires a contract to disclose.

What this page is not

This is general information, not legal advice. It reports one California regulator page. It does not say that any claim will or will not be denied, whether a particular denial was correct, or what your contract or your state's law requires. For your own situation, ask your state consumer protection office or a lawyer.
