The time it takes to replace windows and doors depends on several factors, such as the number of windows and doors being replaced, the type of materials used, the complexity of the installation, and whether the frames need to be replaced as well. Here’s a general idea of how long each type of installation might take:

1. Replacing Windows:

• Standard Window Replacement:
  • For one or two windows, a professional installer can typically replace them in 1 to 2 hours.
  • If you’re replacing all the windows in a home (e.g., 10 to 20 windows), the entire project can take anywhere from 1 to 3 days, depending on the size of your home and the complexity of the installation.
  • This includes removal of old windows, installation of new windows, and any necessary finishing touches such as trim or caulking.
• Factors that Influence Time:
  • Size and Type of Window: Larger windows or custom-sized windows may take longer to install.
  • Condition of the Frame: If the existing window frames need to be repaired or replaced, it will add extra time to the installation process.
  • Window Style: Certain types of windows (e.g., bay windows, double-hung, or casement windows) may require more time to install than simpler, single-hung windows.
  • Weather Conditions: If you’re replacing windows during bad weather or in an area with extreme temperatures, it could slow down the process due to potential challenges with fitting or sealing the windows.

2. Replacing Doors:

• Standard Door Replacement (Exterior Door):
  • Single door replacements (e.g., entry doors, patio doors, or storm doors) generally take about 4 to 6 hours to complete.
  • Double doors or larger sliding glass doors may take a little longer, from 6 to 8 hours.
  • The time estimate includes removing the old door, prepping the frame, installing the new door, and adjusting hardware such as locks and handles.
• Factors that Influence Time:
  • Frame Replacement: If the door frame needs to be replaced (due to damage, rot, or shifting), this will add extra time, often a full day or more.
  • Weather: Like with windows, inclement weather can slow down the process, particularly if the installation requires working outside or with materials that can be affected by moisture.
  • Type of Door: If you’re installing a more complex or custom door, such as a decorative front door, a French door, or a door with special features like sidelights, the installation may take longer.

3. Whole House Window and Door Replacement Project:

• If you’re replacing both windows and doors throughout your home, it can take several days to a full week (or longer) depending on the scope of the project.
• A typical full-home window replacement (for a medium-sized home with 10-20 windows) will take around 2 to 4 days.
• Adding door replacements into the mix might extend the timeline, but if you’re working with an experienced crew, they can often overlap tasks to reduce the overall project duration.

Other Considerations:

• Lead Time for Custom Orders: If your windows or doors are custom-made or need special sizing, they may take several weeks to be manufactured and delivered. This waiting period can add significant time to your overall project.
• Weather and Site Preparation: Severe weather, especially in areas with snow, rain, or high winds, could cause delays, particularly if the installers have to work in less-than-ideal conditions. Additionally, if the work area needs preparation (such as clearing the area, moving furniture, etc.), this could add time.

Summary:

• Windows: Typically 1 to 3 days for a full home (depending on number of windows and complexity).
• Doors: Generally, 1 day for replacing a few doors (up to 6 hours per door), with more time needed if frames need replacement.
• Full Home Replacement (windows + doors): Usually 3 to 7 days, but this can vary depending on the number of units, materials, and complexity.

Before beginning your project, it’s always a good idea to get an estimate of both the timeline and any potential delays from your contractor or window/door supplier.
