There is no one-size-fits-all when it comes to how long replacement windows will last. The reason for this is linked with materials.
For example, vinyl windows can have a lifespan between 20 to 4 years, while wooden windows can last for a minimum of 15 years, and aluminum (metal) windows can last up to 25 years.
This endurance is possible if you maintain your windows right and clean them regularly and with proper cleaning products.
