Visible Damage
Visible damage, such as cracks or chips in the glass or dents or corrosion on the frames, can significantly reduce the performance of your windows.

FAQ
How can I make my old aluminum windows look better?
If you’re looking to improve the appearance of your old aluminum windows, there’s a solution that can restore their color and luster.
Damaged aluminum can be rejuvenated with the use of Everbrite™ coating, which effectively restores the finish of anodized aluminum.
Often, anodized aluminum can become stained or damaged by stucco, mortar, cement, or acid-based cleaners, which can leave unsightly stains and uneven textures.
With the use of Everbrite Coating, you can easily restore the appearance of your aluminum windows and make them look as good as new.
Can aluminium windows be refurbished?
Yes, aluminum windows can be refurbished, but it’s important to note that a professional should do the process.
Cosmetic damage, such as scratches, can be filled and repainted to restore the appearance of the windows.
However, it’s worth noting that anodized aluminum windows can be more susceptible to scratches as the color is the natural color of the aluminum itself. This means that any scratches will be more visible and may require more extensive repairs.
To ensure that your aluminum windows are properly refurbished, it’s best to seek the help of a professional with experience in this area.
How many years do aluminum windows last?
Aluminum windows are known for their durability and are expected to last for around 45 years, which is longer than uPVC frames which have a lifespan of 25-35 years. The lifespan of aluminum windows can vary depending on factors such as the level of maintenance they receive and the conditions they are exposed to.
