Many are swayed by warranty claims of major brands offering 5 or 10-year warranties. It is important to remember that most warranties apply only to replace the cost of the product if the paint is proven faulty. As stated above, paint is usually only 10% of the entire cost of a project. The warranty will not pay for the cost of repainting. There is a lot of research, development and technology in modern paint, and the failure rate is very low, especially in the major brands. That said, it is wise not to choose one paint brand or a painting company because of a product warranty. Other factors, such as an itemized quote, reliability and professionalism should be given greater priority over paint warranty.
