The average cost for a professional window installation typically ranges from $300 to $1,200 per window, including materials and labor, with a national average around $450 to $600 per window.
Prices vary based on window type (vinyl, wood, fiberglass, or aluminum), size, energy efficiency features, and whether it’s a standard replacement or requires structural changes. Vinyl windows tend to be the most affordable, while wood and fiberglass cost more. Labor typically adds $100 to $300 per window.
A full home replacement (10 to 20 windows) often costs between $4,000 and $20,000 depending on quality and home size.
The Cost of Replacement Windows and Installation
