Cost of Energy-Efficient Windows in San Diego (2025 Update)

Energy-efficient windows are a smart upgrade for San Diego homes. They lower heating and cooling costs. They also block noise and improve curb appeal.

But what do they cost in 2025? And what should you know before replacing your old windows?

Average Installation Cost per Window

The cost of window replacement in San Diego ranges from $390 to $1,128 installed.

• Basic vinyl double-pane: $400–$800 installed
• Premium or oversized styles: $1,000+ each
• Full home replacement (10–15 windows): $8,000–$15,000

This price includes both the window unit and professional installation. Labor usually makes up 10–20% of the total cost.

What Affects the Cost of Window Installation?

Several factors change the cost to install windows in San Diego:

• Frame Material: Vinyl is the cheapest ($300–$900). Fiberglass and wood cost more. Premium composites like Fibrex® can exceed $2,000. 
• Type of Windows: Double-hung or sliding windows cost a few hundred. Bay windows or glass doors cost thousands. 
• Double or Triple Pane Glass: Double pane with Low-E and gas fills is standard. Triple-pane is more efficient but 20–40% more expensive. 
• Installation Complexity: Enlarging openings, repairing frames, or upstairs work adds cost. 
• Permits and Removal: Permits cost $50–$150. Removing old windows may add $50–$100 each.

Energy Savings and Long-Term Value

Installing energy-efficient windows cuts utility bills by 7–15% each year.

Benefits include:

• Lower heating and cooling bills
• A steady indoor temperature
• Less outside noise
• Higher resale value

Choosing Energy Star-certified models ensures savings and comfort for years.
