The vast majority of Mastic products are covered by an exclusive V.I.P Limited Lifetime Warranty. This means your products are covered for as long as you live in and own your home, and if you sell your home, the warranty is transferable and the new owners are covered for 50 years from the date of original installation. See the specific terms of our warranty below.
