For construction professionals, accurately estimating the cost of new basement windows is crucial. In 2025, the average cost for a standard replacement hopper window ranges from $900 to $1,400, while an egress casement window with a well and ladder can cost between $3,800 and $6,200. These figures are influenced by regional labor rates and material costs, which are essential for precise budgeting.
Component Cost:
Code Requirements: Egress windows must meet specific size and height regulations, often requiring structural modifications.
Foundation Type: Cutting through block is generally less expensive than reinforced concrete.
Site Logistics: Urban sites may require manual labor, increasing costs.
Finish Level: High-end finishes increase costs, while basic options are more budget-friendly.
Energy Efficiency: Advanced glazing and frames improve efficiency but raise initial costs.
