PVC gutters can last up to 20 years or more, but they may also become brittle and crack after long periods of exposure to the elements.

PVC gutters can last anywhere from 10 to 20 years, but this will depend on a number of factors, including the quality of the installation, the climate in which you live, and how well they're maintained. It's important to remember that PVC gutters are not as strong as metal gutters and may not be suitable for areas that experience high winds or severe weather. If you're considering installing PVC gutters, it's important to consult with a professional gutter installer to determine whether they are the right choice for your home.
