Construction Warranty Explained

A construction warranty is a written commitment from the contractor or builder to repair or replace defective work or materials within a fixed period after project completion. Warranties are split into workmanship (the labor and how it was done) and materials (the products installed).

For a residential remodel, workmanship typically runs 1 to 2 years and material warranties pass through from manufacturers. For new-home construction, builder warranties follow a 1-2-10 structure: 1 year on workmanship, 2 years on mechanical systems, and 10 years on structural elements.

A workmanship warranty covers labor defects. Examples: tile that pops because thinset was applied too thin, drywall cracks where a screw missed the stud, paint that peels because the surface was not primed, a door that sticks because the jamb was set out of plumb.

Workmanship warranties do not cover material defects (a tile that delaminates due to a manufacturer defect) or homeowner-caused damage (a chip in the floor from dropping a frying pan). They cover defects in how the work was performed.

Standard residential workmanship warranty is 1 to 2 years. ContractShield contracts default to a 2-year workmanship warranty unless the contractor and homeowner negotiate otherwise.

A material warranty is from the manufacturer of the product, not the contractor. Examples: a 50-year shingle warranty from CertainTeed, a 10-year warranty on a Kohler faucet, a lifetime warranty on a Marvin window.

Material warranties typically require registration within 30 to 90 days of install. The homeowner is responsible for registration. The contractor should provide model numbers and installation date at project close-out so the homeowner can register each warranty.

Material warranties usually require that the product was installed per manufacturer instructions. A roof installed at a pitch lower than the shingle minimum will void the shingle warranty even if the shingle itself is fine.

The 1-2-10 builder warranty is the standard structure on new-home construction in most US states. One year of workmanship coverage on every element. Two years of coverage on plumbing, electrical, and HVAC systems. Ten years of structural coverage on load-bearing elements.

1-2-10 is often backed by a third-party warranty company (2-10 Home Buyers Warranty is the largest). Third-party backing matters because if the builder goes out of business, the warranty company still honors the claim.

Three categories typically void a warranty: homeowner-caused damage (modifications, neglect), maintenance lapses (failing to clean gutters, failing to register a material warranty), and acts of nature (storms, earthquakes, fires).

Maintenance lapses are the most common void. A shingle warranty often requires periodic roof cleaning. An HVAC warranty often requires annual maintenance by a certified technician. A wood floor warranty often requires humidity control inside the home. Read the void clauses at install, not at claim time.

For workmanship claims, contact the contractor in writing (email, signed letter) describing the defect, the date observed, and any photos. Reference the warranty term in the contract. Contractors typically have 30 to 60 days to assess and 90 days to repair.

For material claims, contact the manufacturer with the registration number, install date, and photos. Manufacturers typically dispatch a field inspector to assess. Approved claims result in product replacement, with labor at the homeowner's expense unless covered by a separate workmanship clause.

ContractShield logs warranty calls inside the project workspace, with timestamps and photos, so the paper trail is automatic.

Every ContractShield project closes out with a written warranty document attached to the contract. The warranty document lists workmanship coverage term, material warranties with model numbers, registration links, and void clauses.

The project workspace stays open for the warranty term. The homeowner can log a warranty call inside the workspace, attach photos, and notify the contractor automatically. Response time is tracked, and review ratings reflect warranty follow-through.

Third-party home warranties are separate from construction warranties. A construction warranty is from the contractor or builder and covers defects. A home warranty (American Home Shield, 2-10, others) is a service contract that covers system breakdowns regardless of cause.

A home warranty makes sense for some homeowners as a budgeting tool. It is not a substitute for a construction warranty. Always have both: a contractor-issued workmanship warranty on the work, and optionally a home warranty on the systems.
