Factors That Affect Window Replacement Costs
Several key factors influence the total cost of replacing windows:
1. Number of Windows
Naturally, the more windows you replace, the higher your total project cost will be. However, you may get a volume discount when replacing multiple windows at once.
2. Window Frame Material
- Vinyl: Most cost-effective and energy-efficient.
- Wood: Offers a classic look but requires maintenance.
- Fiberglass: Durable and energy-efficient but pricier.
- Aluminum: Affordable, but not as energy-efficient in colder climates like Illinois.
3. Glass Options
Upgrading to double-pane or triple-pane insulated glass improves energy efficiency, but also increases upfront costs.
4. Labor and Installation
Labor costs vary depending on window accessibility, whether structural changes are needed, and if there are any unforeseen issues during installation.
5. Energy Efficiency Features
ENERGY STAR®-rated windows can qualify you for rebates or tax credits, which can help offset installation costs.
