"John replaced the glass sash on my Anderson casement windows. He did the complete job in one day, at a cost of 15% of the Anderson replacement window quote. I highly recommend Window MD.. They were perfect!"

"I used Star Windows and Doors LLC to replace the windows in our home. It was a pleasure to work with them - they were very responsive, and from start to finish the entire process smooth. The windows themselves look beautiful, and the installers did a great job with all the little details! I would recommend Star Windows and Doors LLC."

Windows questions, answered by experts

The entire window replacement process, from the initial consultation to the final installation, typically takes between four and 15 weeks. This timeline accounts for measuring appointments, ordering, and manufacturing. On the day of the job, the physical installation takes about 30 minutes to two hours per window. A full-house replacement can take one to three days to complete. Factors that can extend this timeline include the total number of windows, custom sizes, complex window types, second-story installations, and any necessary repairs to existing window frames or openings.

Typically, a bay window is, at minimum, 42 inches wide. That said, you can always design a custom bay window that is smaller—box bay windows are usually less than three feet in width and are ideal for smaller spaces.

Removing a window isn’t a very long process. Depending on several factors, it can take anywhere from 20 minutes to upwards of an hour. The size of the window greatly impacts the time it takes to replace it. Accessibility is another big component. If it’s hard to reach the window or reaching it is dangerous, anticipate it taking longer. 

Lastly, if the old window is in poor condition, it could take longer to remove it safely—especially if the frame has wood rot and is structurally unsound.

You can choose 5/8-inch plywood or 3/4-inch plywood—anything thinner than these sizes may not withstand the impact of debris propelled by strong winds or can be easily torn off by intruders. Remember that the durability of the wood board is crucial, particularly for safeguarding your windows during severe storms. The effectiveness of using wood boards for protecting the investment you made in your home relies on using the appropriate material and ensuring proper installation.

While some homeowners are under the impression that triple-pane windows can help to reduce sound, the truth is that triple-pane windows will not be much quieter than double-pane windows since having a third pane doesn’t make much difference in sound transmission. If you’re looking to reduce sound, you should consider installing laminated glass windows.
