When considering new windows for your home, one of the most common questions homeowners ask is, “How long does window installation take?” Whether you're replacing old windows with energy-efficient models or installing windows in a brand-new home, understanding the installation timeline can help you plan more effectively and minimize disruptions to your daily routine.
At Newman Windows & Doors, we know that every home improvement project comes with a mix of excitement and uncertainty. That’s why we’re here to provide clarity and transparency around the window installation process so you can make confident decisions for your home.
Factors That Affect Window Installation Time
The length of time required for window installation can vary depending on several factors. Understanding these will give you a clearer idea of what to expect for your specific project.
- Number of Windows Being Installed: Naturally, the more windows you’re having installed, the longer the process will take. A single window can often be installed in under an hour, but a full-home installation could take several days depending on the size and complexity of the project.
- Type of Windows: Standard-sized, single-hung or double-hung windows are typically quicker to install than custom-shaped or specialty windows like bay, bow, or garden windows, which may require additional framing or support.
- Condition of Existing Frames: If the existing window frames are in good shape, installation is generally quicker. However, if there is rot, damage, or other structural issues, additional time will be needed for repairs or replacements.
- Accessibility: Windows on upper floors or in hard-to-reach locations may take longer to install due to the need for special equipment or additional safety measures.
- Type of Installation: There are two main methods of window installation—full-frame replacement and retrofit (or insert) installation. Full-frame replacements take more time as they involve removing the entire window, including the frame and trim.
Average Timeframe for Window Installation
While the specifics can vary, here are some general guidelines to help you estimate how long your window installation project might take:
- Single Window: Typically takes 30 minutes to 1 hour, assuming standard conditions and accessibility.
- Small Project (2–5 windows): Often completed in a half-day to a full day.
- Medium Project (6–10 windows): Usually completed in 1 to 2 days.
- Large Project (11+ windows or full-house installation): May take 2 to 4 days, depending on window types, installation methods, and site conditions.
These timelines assume favorable weather and no major structural issues. At Newman Windows & Doors, our professional installers work efficiently while maintaining a high standard of craftsmanship and cleanliness to ensure the best results with minimal disruption to your home.
Pre-Installation Preparation
Proper preparation before the installation crew arrives can make the process go even more smoothly and may even shorten the time needed to complete the project. Here are a few things you can do in advance:
- Clear access to windows: Move furniture, curtains, and blinds out of the way to provide a clear path for installers.
- Deactivate security sensors: If your windows are connected to a security system, be sure to deactivate or remove sensors beforehand.
- Secure pets: For their safety and to avoid disruptions, keep pets in a separate area during installation.
- Communicate any concerns: Let your installer know about any areas of concern or preferences so they can address them during installation.
What to Expect During Installation
On installation day, the Newman Windows & Doors team arrives on time and ready to work. Our process typically includes:
- Setup: We begin by protecting your floors and furnishings with drop cloths and prepping tools and materials.
- Removal of Old Windows: Carefully remove existing windows, checking for and addressing any signs of damage or rot in the frames.
- Installation of New Windows: The new windows are fitted, leveled, and secured. We ensure a snug fit to maximize energy efficiency.
- Sealing and Insulating: Gaps are sealed with high-quality insulation and caulking to prevent drafts and moisture intrusion.
- Finishing Touches: Interior and exterior trim is reinstalled or replaced as needed, and we clean up thoroughly before leaving.
