Aluminum Frames
Aluminum frames are easily the most affordable of the bunch but not the most versatile. They tend to lack in the efficiency and insulation department, making them less of a practical choice. Should that not be an issue, however, you can replace aluminum windows for an average of $100 to $420 per unit — which is ideal if you’re on a tight budget.
Fiberglass Frames
Although fiberglass window frames share the same benefits as their vinyl counterparts in terms of durability, energy efficiency, and aesthetic value, they tend to be more sturdy. As a homeowner in California, you can expect to pay between $460 to $1,600 for replacing a fiberglass window.
Composite Frames
Composite frames consist of a mix of PVC polymers, offering the same aesthetic versatility of wood as well as the durability of vinyl. Windows with composite frames are also energy efficient, meaning that you can save money down the line. Composite replacement window prices in California typically range from $345 to $1,400 per unit.
