Yes, we provide energy-efficient window solutions designed to improve your home’s energy efficiency, reduce energy bills, and enhance overall performance.
Yes, you can replace windows without replacing the existing window frames, as long as the existing frame is in good condition. This is typically done using a pocket window installation, where the new replacement window is fitted into the existing window opening. This method preserves the original window frame, making the process quicker and more cost-effective than a full frame replacement.
However, if the existing window frames are damaged or you want to change the window type, size, or style (like upgrading to full frame windows for better energy savings), you might need a full frame replacement. For older homes or frames showing signs of rot, a complete replacement is recommended to ensure proper insulation and curb appeal.
Smaller tasks like replacing a lower sash or installing smaller windows can be done without changing the frame, but larger changes often require full frame replacements. We always recommend hiring professionals to assess your existing windows and help you decide on the best approach.
The time it takes for a window replacement installation depends on several factors, such as whether you’re installing full frame replacement windows or working with existing frames. For standard replacement windows, the process typically takes about 30 minutes to 1 hour per window.
If you’re opting for full frame replacement windows, it might take longer, especially if additional work is needed to remove the wood windows, adjust the solid wood frame, or use a utility knife to carefully remove parts of the old frame. Installing features like custom colors, low maintenance finishes, or other materials may add time as well.
For larger windows with two sashes or difficult-to-reach areas, it may also take longer. On average, a complete window replacement project for a house can take 1-2 days, depending on the number of windows, access to the areas, and any additional work like fitting doors or addressing paint and maintenance needs.
