Short answer. Yes. Article 1714 says that when a contractor produces the work from his own materials, he must transfer dominion over the thing, and the contract is governed by the rules on warranty of title and against hidden defects in a sale. So his finished work carries the same hidden-defect protection a buyer gets.
What the law says
This contract shall be governed by the following articles as well as by the pertinent provisions on warranty of title and against hidden defects and the payment of price in a contract of sale.

Work from the contractor's own materials is treated like a sale
Article 1714 addresses a specific arrangement: the contractor agrees to produce the work using material he himself furnishes. In that case he must deliver the finished thing to the employer and transfer dominion over it, and the law adds that this contract shall be governed by the following articles as well as by the pertinent provisions on warranty of title and against hidden defects and the payment of price in a contract of sale. Because the contractor supplies both labor and materials and ends up conveying a finished object, the transaction closely resembles a sale of that object, and the Code borrows the sale's warranty rules to govern it.
What the hidden-defect warranty gives you
Bringing in the sale rules means the finished work carries a warranty against hidden defects, flaws not apparent on ordinary inspection that make the thing unfit for its purpose, or that would have stopped you accepting it or led you to pay less had you known. If such a defect surfaces, the employer generally has the remedies a buyer would: to demand a proportionate reduction in what he pays, or in a proper case to undo the transaction, and to recover damages where the contractor knew of the defect. There is also the borrowed warranty of title, protecting the employer's ownership of what he receives.
Why it matters who supplied the materials
The trigger in Article 1714 is that the contractor furnished the materials. This is what tips the contract toward a sale of a finished product and pulls in the sale warranties. Where instead the employer supplies the materials and the contractor only contributes labor and skill, the relationship is more purely one for a piece of work, and it is governed by the rules on that kind of contract rather than being treated as a sale. So the same craftsman can stand in a different legal position depending on who provided the raw materials. Identifying which situation you are in decides which protections and time limits apply.
Acting on a hidden defect in time
The practical catch with the sale warranty is that its remedies come with short time limits, so a hidden defect must be raised promptly once discovered rather than left to fester. Keep the contract, the specifications and records of delivery and acceptance, because whether a defect is truly 'hidden', as opposed to one you could have seen and accepted, is often the contested point. If a contractor supplied the materials and the finished work later proves defective beneath the surface, Article 1714 gives you a real claim, but one you must assert within the periods the sale rules impose. Delay is the most common way the protection is lost.
