A home warranty can be purchased at almost any point during homeownership — when you are buying or selling, years into owning the home, as a builder’s new-construction coverage winds down, or at the end of an existing contract term. The timing you choose affects three things: whether a waiting period applies before you can file a claim, how pre-existing conditions are treated, and in some cases who pays the premium.
During a Real Estate Closing
The most common time to buy is at closing. Buyers often negotiate for the seller to pay the premium as part of the purchase agreement, and the cost appears as a line item under “Other Costs” on the federal Closing Disclosure, paid from the sale proceeds at settlement.1Consumer Financial Protection Bureau.

The practical advantage of buying at closing is that most providers waive the standard waiting period. Coverage begins the day the transaction closes rather than 30 or more days later.
Sellers can also buy a warranty while the home is listed, covering systems and appliances during the marketing period. If a covered item fails after the listing warranty is in place but before the sale closes, the contract can pay for the repair, preventing a surprise breakdown from derailing the deal.
Any Time After You Already Own the Home
You do not have to be buying or selling to get a warranty. Providers accept applications for existing homes at any point during ownership, regardless of the home’s age, as long as covered systems and appliances are in working order when the contract starts. Many homeowners add coverage after a few years, once appliances begin aging and repair bills become less predictable.
The Waiting Period
A policy purchased outside a real estate transaction comes with a waiting period, typically 30 days, though some providers impose waits of up to 60 or 90 days. You pay the premium during that window but cannot file claims. The rule exists to stop people from signing up after a system has already failed. If your air conditioner breaks during the initial window, the claim will be denied.
Pre-Existing Conditions
Even after the waiting period ends, providers will not cover problems that existed before coverage began. A pre-existing condition means any malfunction or defect that would have been detectable through a visual inspection or a simple mechanical test, even if you had no idea the issue existed. When you file a claim, the warranty company sends a technician to diagnose the problem. If the technician determines the failure predates the contract, the claim is denied. Some providers offer coverage for items with known pre-existing issues, but at a higher premium.
Most warranty companies do not require a formal home inspection before selling you a plan. Keeping inspection records from a recent purchase can help support a later claim by documenting that systems were functioning when coverage started.
As a Builder Warranty Winds Down
New-construction homes come with builder warranties that follow a tiered structure. Workmanship and materials coverage on components like siding, doors, drywall, and paint typically expires after one year. Protection for heating, cooling, plumbing, and electrical systems generally lasts two years. Some builders provide coverage for major structural defects, sometimes defined as problems that make the home unsafe, for up to ten years.2Consumer Advice – FTC. Warranties for New Homes
Builder warranties usually do not cover household appliances or items already protected by a manufacturer’s warranty.2Consumer Advice – FTC. Warranties for New Homes A private warranty fills that gap. Purchasing a third-party contract around the eleventh month of ownership, before the first-year builder coverage lapses, keeps systems and appliances continuously protected.
The handoff matters most for HVAC and plumbing. Once the builder’s two-year systems coverage expires, a private warranty keeps those items protected. Without one, any repair that falls outside the structural defect category becomes an out-of-pocket expense.
At Renewal
Most home warranty contracts run one year. The provider sends a renewal notice and updated quote before the term ends, and premiums and coverage terms can change. Review the new offer carefully, particularly any adjustments to per-item payout caps or the aggregate coverage limit, which is the maximum the company will pay across all claims in a single contract period.
Timing is the critical detail. Renew before the current term expires and coverage continues without interruption, with no new waiting period. Let the contract lapse, even briefly, and most providers treat the next policy as a brand-new purchase. That means a fresh 30-day waiting period and potentially a new pre-existing condition evaluation. Any system that developed a problem during the lapse would likely be excluded from the new contract.
What a Home Warranty Will Not Cover Regardless of When You Buy
The timing of your purchase controls waiting periods and pre-existing condition reviews, but certain exclusions apply to every contract:
- Repairs tied to improper installation or systems that do not meet building codes.
- Damage traced to neglected routine maintenance, such as never changing an HVAC filter.
- Damage you cause deliberately.
- Cosmetic issues, including dents, scratches, and surface problems that do not affect function.
- Pre-existing conditions detectable before the contract started.
Payout caps also vary by provider and plan tier. Air conditioning caps can range from roughly $1,500 to $6,000, and appliance caps from $500 to $7,000. Some providers set an aggregate limit for all claims during the term. Review these numbers before buying, because a low cap on an expensive system could leave you covering most of a replacement yourself.
Cancellation If the Timing Does Not Work Out
If you buy and then change your mind, most providers allow mid-term cancellation with a pro-rata refund — the unused portion of your premium, minus any claims already paid and an administrative fee. Many states cap the administrative fee by regulation, with the specific limit varying by jurisdiction. Some states also require a short cooling-off period after purchase, often around 10 to 30 days, during which you can cancel for a full refund with no penalty. Check your contract for the exact terms, since they differ by provider and state. Home warranty service contracts are typically regulated at the state level, most often by the state’s department of insurance.
