How to Repair a Vinyl Window Frame
Last Updated: Mar 17, 2025Vinyl windows are increasingly popular for their excellent insulation, ease of maintenance, and variety of available styles.
Nothing quite compares to the weather protection and energy efficiency of a double or triple pane vinyl window for a sustainable home. And, unlike wood and aluminum windows, vinyl windows are less likely to fade, bend, warp and peel.
Like any exterior element to your home, vinyl windows are susceptible to damage from hail, windstorms, and human error. While some damage made requires the replacement of the entire window, it’s always best to consider whether it can be repaired first. Why?
The average vinyl window should last about 10-20 years. If your windows are newer than that, it’s almost always more sustainable to seek a repair first. Replacing an entire window costs $400-$600 each. A professional repair runs about $175 per window, saving you a great deal of money. Repairing also reduces unnecessary waste.
Can Vinyl Windows Be Repaired?
Yes! It is possible to repair most damage to vinyl window frames. Some repairs are even simple enough that you can do them yourself.
The structure of a vinyl window is a careful composition of two to three panes of glass separated by a gap, often filled with gas, and sealed tightly with a PVC sash held tight to the windows by welding.
Common Problems Requiring Repair Include
- Cracks in the window frame
- Holes in the window frame
- Broken window seal
These vinyl window problems can arise naturally as your house settles, from weather, or if you happen to hit the window from the inside or outside by accident. Checking your windows after a storm or when a fly ball hits the house will help you spot problems quickly. Making immediate repairs will improve your home’s insulation and energy efficiency.

How to Repair Small Vinyl Window Frame Issues Yourself
Before beginning any repair to your vinyl window frames, start by determining how much vinyl you’ll need. If you notice a hole in one window, it’s always best to check the rest of your windows and get all cracks and holes taken care of at one time.
Using a tape measure, measure each crack and hole, taking note of your measurements. Then, add all needed repairs together to determine how much vinyl is required. Take your time to measure each issue twice, so you don’t run out of material during the repair process.
Once you have your materials ready, it’s time to start your vinyl window repair. It’s best to begin in the evening or on an overcast day, as adhesive needs 24 hours to dry, and direct sunlight can lead to warping. If that’s impossible, position an umbrella or sunshade over the window to prevent direct sunlight from hitting the window.
Unlike aluminum and wood-framed windows, it’s not simple to replace the glass in a vinyl window. The glass of a vinyl window is manufactured with the sash attached, so it’s imperative your order the exact glass for a perfect fit. A professional window installer can help you order the right one and install it carefully to avoid breaking the glass and ensure the new seal is tight.
If you must replace the window, ask about high-quality vinyl windows that (a) have a longer life and (b) have “double warranties” that carry on to second owners. Both of these will provide value to your home should you sell before the windows meet the end of their life.
