Contractor Warranty vs. Home Warranty: What's Actually Covered

Q: How long does a contractor's workmanship warranty typically last?

There's no single legal standard, but 1-2 years is common in the industry for general workmanship, while structural work is sometimes warrantied longer. Always get the specific warranty period and what it covers in writing as part of your contract, not as a verbal assurance.

Q: Does a home warranty cover a leak caused by a remodel?

Usually not if the leak stems from installation error during a recent remodel — that falls under the contractor's workmanship warranty, not a home warranty, which is designed to cover mechanical failure of existing systems and appliances from normal wear, not construction defects.

"Warranty" gets used loosely in home renovation, and it covers at least three genuinely different things: your contractor's workmanship warranty, a home warranty service plan, and manufacturer warranties on the fixtures and appliances themselves. Knowing which one applies before something goes wrong saves a lot of frustration after the job is done.

What a Contractor's Workmanship Warranty Covers

This is the contractor's promise that their labor and installation was done correctly. If a tile installation cracks because it wasn't set properly, if a door doesn't hang right, or if a newly installed fixture leaks because of an installation error, that's a workmanship warranty claim against your contractor — not a home warranty issue. Get the specific warranty period and scope in writing as part of your contract, not as a verbal promise. Typical terms run 1-2 years for general workmanship, though some contractors warranty structural work longer.

What a Home Warranty Covers (and Doesn't)

A home warranty is a separate service contract, usually purchased annually, that covers the repair or replacement of home systems and appliances (HVAC, water heater, plumbing, electrical) when they fail from normal wear and age — not from installation defects. Critically, most home warranty companies will deny a claim if they determine the failure traces back to improper installation during a recent remodel, which routes you back to the contractor's workmanship warranty instead.

	Contractor Workmanship Warranty	Home Warranty
Covers	Installation errors and defects in labor	Mechanical failure from normal wear/age
Who provides it	Your general contractor	A third-party home warranty company (paid annually)
Typical duration	1-2 years (negotiable, get it in writing)	Annual, renewable
Covers a leak from a badly installed fixture?	Yes	Usually no — considered a construction defect

Manufacturer Warranties on Fixtures and Appliances

Separately, the individual products installed during your remodel — the range, the water heater, the plumbing fixtures — carry their own manufacturer warranties, typically covering defects in the product itself for anywhere from 1 to 10+ years depending on the item. Keep your product manuals and registration confirmations; many manufacturers require product registration within a set window after installation for the warranty to apply.

What Happens If Something Goes Wrong After the Job Is Done

Identify what actually failed — a product defect, an installation error, or normal wear
If it's an installation issue, contact your contractor directly under their workmanship warranty first
If it's a product defect, the manufacturer's warranty applies, though your contractor can often help facilitate the claim since they have the install documentation
Document everything — photos, dates, and any correspondence — from the moment you notice the issue

A contractor who stands behind their work will still be reachable and responsive well after final payment. That responsiveness — more than the specific number of months on paper — is usually the real difference between a warranty that means something and one that doesn't.
