AZEK decking is prone to manufacturing issues including deterioration, cracking, sagging and lifting, as of 2015. The material also has design defects including discoloration, fading, staining, scratching and chalking, states FineHomeBuilding.com.
AZEK claims its product outperforms both wood and composite decking and offers lifetime warranties on its products to support that claim. However, both AZEK and parent company CPG have had numerous lawsuits filed against them because of denied warranty claims, as AZEK and CPG claimed that the reported problems were aesthetic in nature and not performance related. The plaintiffs in these cases are spread across New Jersey, Illinois, Massachusetts, Maryland, Virginia and Connecticut. According to Plastics News, damages from the lawsuits could eclipse $5 million.
According to Seeger Weiss LLP, the law firm representing the plaintiffs in these cases, AZEK’s advertisements claim that their decking product is stain resistant and scratch resistant. However, products such as suntan lotion and bug repellent discolor the material and many customers report problems with scratching.
AZEK's typical solution is to send a maintenance crew to clean and condition defective decks. However, customers do not find that this is an effective long-term solution. Alternatively, customers can purchase a conditioner for $60 to $100 on top of what they have already paid. Homeowners find that neither option permanently solves the problem.
