How Long Do Replacement Windows Last? A Guide to Durability & Longevity

Investing in Long-Lasting Windows for Your Home 

When considering replacement windows, longevity is one of the most important factors. Homeowners want to know how long their investment will last before needing another upgrade. The good news? High-quality replacement windows, especially those from Renewal by Andersen, are designed for durability and lasting performance.

In this guide, we’ll explore the lifespan of replacement windows, what factors impact their longevity, and how you can ensure your new windows stand the test of time.

How Long Do Replacement Windows Last? 

The lifespan of replacement windows varies depending on the material, quality of installation, and maintenance. On average: 

  • Vinyl Windows – 20 to 30 years
  • Wood Windows – 15 to 20 years (unless properly maintained)
  • Aluminum Windows – 20 to 25 years
  • Composite Windows (like Fibrex® by Renewal by Andersen) – 40+ years

Renewal by Andersen’s Fibrex® windows are designed for long-term durability, outperforming traditional vinyl and wood windows. Fibrex® combines the best qualities of wood and vinyl, resisting rot, warping and cracking over decades. 

What Affects Window Lifespan 

Several factors determine how long your replacement windows will last: 

Window Material 

As mentioned, different materials have varying durability. Fibrex® composite windows offer one of the longest lifespans, withstanding extreme temperatures and wear without losing efficiency.

Installation Quality

Even the best windows can fail if they aren’t installed correctly. Poor installation leads to air leaks, moisture damage, and premature wear. That’s why professional installation by Renewal by Andersen ensures maximum performance.

Climate & Weather Conditions

Harsh winters, high humidity, and strong winds can damage window materials. Fibrex® windows are designed to withstand Wisconsin’s varying climate without warping, expanding, or deteriorating over time.

Maintenance & Upkeep

Some windows require more maintenance than others. Vinyl and composite windows require minimal upkeep, while wood windows need regular painting and sealing to prevent rot.

Signs It’s Time to Replace Your Windows 

Not sure if your current windows need an upgrade? Look for these signs: 

  • Drafts or air leaks
  • Condensation between panes
  • Difficulty opening or closing 
  • Increased energy bills
  • Visible damage or warping

If you notice any of these issues, it might be time to invest in durable, energy-efficient replacement windows. 

Maximize the Longevity of Your Replacement Windows 

To get the most out of your replacement windows: 

  • Choose high-quality materials like Fibrex®
  • Work with expert installers to ensure a proper fit
  • Perform occasional maintenance (cleaning, checking seals, etc.)

Hear From Our Customers

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgeable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.
