Replacement windows are generally built to last for several decades, but their lifespan can vary depending on several factors, such as the materials used, the climate in which you live, and how well the windows are maintained. Here’s a breakdown of how long replacement windows typically last:
Vinyl Windows: These are the most common type of replacement windows and are known for their durability. With proper maintenance, vinyl windows can last anywhere from 20 to 40 years or more. They are resistant to fading, cracking, and warping, making them a popular choice for long-term performance.
Wood Windows: Wood windows can last 30 to 50 years or longer if properly maintained. However, they require more upkeep, such as periodic painting or staining to prevent rot, warping, and weather damage. If well-maintained, wood windows can be a very durable option.
Aluminum Windows: Aluminum windows are typically good for 20 to 30 years, but they can be prone to corrosion, especially in coastal or humid areas. Modern aluminum windows often have a protective coating to help them last longer.
Fiberglass Windows: These are one of the most durable types of windows, lasting anywhere from 30 to 50 years or more. Fiberglass windows are resistant to warping, rotting, and UV damage, making them a great long-term investment.
Ultimately, most modern replacement windows come with warranties ranging from 10 to 50 years, depending on the manufacturer and type of window. These warranties often cover defects in materials and workmanship but may not cover damage due to external factors like storms or improper installation.
