External work comes with a workmanship warranty that nobody reads after the day it is signed. It goes into a folder, the person who signed it moves on, and the site inherits a defect with a live warranty nobody knows about. So the defect gets quoted. Somebody comes out, prices the repair, and the operator pays for work a contractor was still contractually on the hook for. In the twin, the warranty sits on the element it covers, with the term, the contractor and the expiry.
The pavers on the entrance walkway are lifting, and the question is whether the installer gave any warranty. They did: five year workmanship, fourteen months still to run, the installer’s contact sitting on the element they laid. The copilot adds the thing worth knowing — lifting on a walkway carrying that much foot traffic is usually base settlement, which is workmanship rather than wear. The question about a defect answers with who is liable before it answers with what it costs.
