A builder warranty is the builder's written promise, given as part of the sale, that its own work meets the standards in the document for a set period. A home warranty is a service contract you buy from a separate company that pays for repairs to systems and appliances, for a fee per visit, for a set term. The builder warranty covers construction defects; the home warranty covers breakdowns. Neither one covers the other's territory, and a new home usually also has a third layer: the manufacturer warranties on its equipment.
This post is about which document covers what, and which one to open when something fails. For how to read the builder warranty itself, the guide to reading a builder warranty goes clause by clause.
What is a builder warranty?
A builder warranty is a contract between the builder and the buyer, delivered at or before closing, that promises to repair defects in the builder's workmanship, materials, systems, and structure within stated periods and stated tolerances. It costs nothing extra because it is part of the purchase. It is the builder's promise, and sometimes a third-party warranty company administers it, but the buyer does not choose the company or the terms.
The common shape narrows as it lengthens: the shortest period covers workmanship and materials, a middle period covers the delivery systems (pipes, wires, ducts), and the longest covers load-bearing structure. What a 1-2-10 warranty usually covers walks through that shape and its exclusions. The point for this comparison is what kind of failure the builder warranty answers: something was built or installed wrong, and the document's standards say so.
What is a home warranty?
A home warranty is a service contract. The Federal Trade Commission's consumer alert on home warranties puts it plainly: home warranties are really service contracts, they cost extra, and they typically cover replacements and repairs for things like appliances or air conditioning systems for a set amount of time. You pay a yearly premium, and a fee each time a technician comes out. The company chooses the technician and decides what the contract covers.
The FTC's page on extended warranties and service contracts says a service contract is different from the warranties that may automatically come with a product, that it costs extra and might cover different issues than a manufacturer's warranty, and that the value of an extended warranty or service contract is only as good as the company that is responsible for coverage.
The kind of failure a home warranty answers is a breakdown from use and age: the water heater stops heating, the air conditioner's compressor fails, the dishwasher pump quits. It does not answer a defect in how the house was built, and most contracts exclude problems that existed before the contract started, problems caused by improper installation, and problems that follow from skipped maintenance. Read the exclusions before the coverage list; that is where the contract is decided. The service contract explainer goes through the terms in detail.
How do the two compare?
The two documents differ in who gives them, what they cost, what triggers a claim, who does the repair, and how long they last. The builder warranty is free, covers defects, sends the builder or its subcontractor to fix them, and runs in tiers from closing. The home warranty is paid, covers breakdowns, sends the company's contractor, charges a fee per visit, and renews yearly. Put side by side, they overlap less than most owners expect.
| Question | Builder warranty | Home warranty (service contract) |
|---|---|---|
| Who provides it | The builder, sometimes through a warranty administrator | A service contract company you or the seller chose |
| What it costs | Included in the purchase | A yearly or monthly premium plus a fee per service call |
| What triggers a claim | A defect that fails the document's standards | A covered system or appliance stops working from normal use |
| What it commonly excludes | Appliances and equipment, normal wear, owner damage, items within tolerance | Pre-existing conditions, improper installation, lack of maintenance, items or parts not listed |
| Who does the repair | The builder or its subcontractor | A contractor the company assigns |
| How long it lasts | Stated tiers from closing, longest for structure | The contract term, usually renewed yearly |
| Where the rules live | The warranty document and the purchase contract | The service contract and its exclusions schedule |
The FTC's alert suggests asking before buying a home warranty whether it is likely to save money considering the upfront cost and hidden costs like deductibles or fees, whether there are limits on reimbursement, whether certain appliances or systems are excluded, whether accidental damage is covered, whether there are cancellation restrictions or fees, and whether the claims process seems difficult or slow. Ask the same questions about a contract a seller or a sales office included with the house.
Where do manufacturer warranties fit?
Manufacturer warranties are the third layer, and in a new home they are usually the ones you use most. The furnace, the air conditioner, the water heater, the roofing shingles, the windows, the siding, and every appliance each carry a warranty from the maker, with its own start date, term, registration step, and maintenance condition. Builder warranties commonly exclude this equipment because the manufacturer already covers it, and a home warranty usually excludes anything still under a manufacturer's warranty.
That makes the first year or two of a new home a period when a home warranty has the least to do. The builder covers the construction, the manufacturers cover the machines, and the service contract would mostly be paying for coverage that already exists. Registering those manufacturer warranties in the first month is the task that makes the layer real; an unregistered warranty with no proof of the install date is harder to use.
Which one should you call when something breaks?
When something fails, decide which document answers it by asking what kind of failure it is: a defect in the builder's work goes to the builder warranty while it is in force, a failed piece of equipment goes to its manufacturer warranty while that is in force, and a breakdown from use on an item a service contract lists goes to the service contract. Sudden damage from an event goes to the insurer. Check them in that order, because the free coverage comes first.
The same failure can touch two documents, which is why the record matters. The claim to the builder needs the date you noticed the leak and the photos; the claim to the manufacturer needs the model, serial, install date, and the service history; the insurer needs the photos and the receipts. If every warranty in the house is on the Warranties list with its end date and its document, the order of calls is a glance rather than an afternoon. Property Station builds that list from the dates on your systems, your documents, and the builder connection, so there is no separate list to keep.
Should a new-construction owner buy a home warranty?
For most new-construction owners, a home warranty adds little in the first year or two, because the builder warranty and the manufacturer warranties already cover most of what it would. The question opens again as those expire: once the systems period closes and the appliance warranties run out, a service contract covers the same breakdowns that a repair fund would. Decide with the FTC's questions and a yearly cost comparison, not with the brochure.
We recommend treating a home warranty as a budgeting choice, not a safety net. Work out its yearly cost including the per-visit fee, compare it with what you would put aside for repairs on the same equipment, and read the exclusions for the items you actually worry about. A contract that excludes the air conditioner's compressor is not covering the failure you bought it for.
None of these three documents is homeowners insurance, which covers damage from events rather than defects or wear, and which a new home needs at closing regardless.
Common questions
Do I need a home warranty on a new construction home?
Usually not in the first year or two, because the builder warranty and the manufacturer warranties on the equipment cover most of what a home warranty would. The case gets stronger as those expire. Run the FTC's questions against the contract before buying, and compare the yearly cost with what you would set aside for repairs anyway.
Can I have both a builder warranty and a home warranty?
Yes, and some new homes come with both because the builder or the sales office included a service contract. They do not conflict; each covers different failures. When something breaks, check the builder warranty first while it is in force, then the manufacturer warranty, then the service contract.
Which warranty covers the appliances in a new home?
The manufacturer's warranty, not the builder's, in most cases. Builder warranties commonly exclude appliances and equipment because those items carry their own warranties from the maker. A home warranty may cover appliance repairs once the manufacturer warranty ends, subject to its own terms.
Does homeowners insurance overlap with either one?
Only at the edges. Insurance covers sudden damage from an event such as a fire, a storm, or a burst pipe, not a defect or a worn-out part. A pipe that leaks because it was installed badly is a warranty matter; the ruined floor beneath it may be an insurance matter. Read all three documents for the boundaries.
What should you do next?
Find all three kinds of document for your house, write each one's end date on its first page, and enter the dates where you will see them before they pass. Then read the builder warranty with a pen, because its deadlines come first, and set up the maintenance the manufacturer warranties expect with the first-year schedule for a new build.
