Frequently Asked Questions About Window Replacement
1. How long does a window replacement take?
For most homes, window replacement can be completed in as little as one day per room. The exact timeline depends on the number and type of windows being replaced, as well as the condition of the existing frames.
2. What are the benefits of energy-efficient windows?
Energy-efficient windows reduce heat loss in winter and keep cool air inside during summer. This lowers your energy bills, increases indoor comfort, and contributes to a greener home. They also help reduce outside noise and offer better UV protection.
3. Can I replace just one window, or do I need to do all of them?
Yes, you can replace just one window. While replacing all windows at once offers the most energy and aesthetic benefits, we’re happy to work with your priorities and budget—whether that means tackling one room or the entire house.
4. Do I need to be home during installation?
We recommend being home at the start and end of the project to ensure access and walk through the work. That said, many of our clients trust our licensed and insured crew to work independently after a brief orientation.
5. What types of windows do you offer?
We install a wide variety of window types, including double-hung, casement, bay, picture, sliding, and custom styles. During your free consultation, we’ll show you all your options and help you choose the best fit for your home and goals.
