Construction warranty vs. workmanship claims: What’s the difference?

On Behalf of | May 8, 2025 | Construction Law |

When something goes wrong on a construction project, it is easy to feel overwhelmed. After all, it is a big and delicate project to make mistakes. For many Arizona homeowners or builders, figuring out whether the issue falls under a warranty or a workmanship claim can be confusing. 

Arizona contractors and workers take pride in their craft. But even skilled professionals can find themselves facing complaints. Sometimes, the problem is not about a lack of effort—it is about understanding what kind of issue has occurred and how the law treats it.  

Two paths, two purposes 

While both warranty and workmanship claims deal with construction problems, they are not the same. 

  • Workmanship claim: This type of claim focuses on the quality of the work done. A workmanship claim may arise if a contractor or worker fails to meet basic trade standards or the agreed terms. It usually applies to errors caused by poor skill, lack of care or failure to follow codes. Examples include crooked tile installation, uneven flooring or leaky plumbing from careless work. 
  • Construction warranty: This is a written warranty that promises that certain parts of the project will last for a set time. In Arizona, builders often provide a one- or two-year warranty on things like roofing, windows or appliances. If these items break down within that time—not because of bad work, but because they are faulty or wear out too soon—a warranty claim may apply. 

The key difference is how the problem happened: 

  • If the issue comes from bad work, it results in a workmanship claim. 
  • If it comes from a product failure or breakdown, it is likely a warranty issue. 

Understanding this difference can help homeowners and builders take the right steps and avoid wasted time. 

If dealing with a faulty build or a client complaint in Arizona, it is okay to ask for help. Construction law is detailed, and the wrong move can lead to delays or costs. Therefore, it is wise to seek the assistance of a legal professional with a deep understanding of Arizona’s construction rules.
