Upgrading your windows enhances the look and comfort of your home, but the replacement window installation process can seem overwhelming. From choosing the right windows to finding the best installer, there are many factors to consider. But don’t worry — we’re here to help.

In this blog, we’ll share helpful information on the replacement window installation process, including tips for a successful and stress-free upgrade.

What Do You Need?

Before diving into the installation process, take the time to evaluate your needs and goals. Are you looking to improve energy efficiency? Does something not work the way it should? Do you want to make your home more beautiful? All of the above? Consider your budget, styles, and features. This little bit of research will get you started in the right direction.

After you’ve given some thought to your needs, it’s time to bring in the experts. Infinity works with a network of dedicated local experts.

Choose the Right Installation Method

Yes, there’s more than one way to install windows. Maybe the area surrounding your windows is in perfect condition. Maybe there’s water damage. Infinity provides two window replacement methods, insert and full-frame, tailored to suit the age and style of your home. Your local Infinity partner will walk you through your options and recommend the best option. Both methods are designed to optimize efficiency while minimizing any disruptions to your home.

Insert Replacement: New windows are installed within the existing frame. Only the old sash, hardware, and covers are removed and replaced.

Full-Frame Replacement: Existing windows are completely removed down to the studs, and the new window is installed in the opening.

Choose the Right Windows

Choosing the right replacement windows is crucial for achieving your desired results. Look for windows that are durable, match your home's architectural style, and meet your functional needs. Consider the material, glass options, and other features such as Low-E coatings, multiple panes, and more. Infinity fiberglass windows are built for strength, beauty, and come in a variety of options to meet your needs. Consult with your local expert to ensure that you select the best windows for your home.

Preparing for Installation Day

Preparing for installation is easy and will help speed things along. Prepare the area around the windows by removing curtains, blinds, and any other window treatments. Clear the surrounding space to provide easy access for the installation team. Next, the old windows will be removed. This involves taking out the window sashes, removing the old frame, and thoroughly cleaning the opening to ensure a clean and smooth installation.


Congratulations! You picked your windows and you’re just a few steps away from enjoying your updated home. The installation process begins by inserting the new window into the opening. The window is leveled and secured using screws or nails. The installer ensures a proper fit, seals any gaps or openings, and insulates around the window frame to prevent drafts and energy loss. They also test the functionality of the window, ensuring it opens, closes, and locks properly.

Finishing Touches

After the window is securely installed, the installer will add the finishing touches. This includes adding exterior trim or casing to enhance the visual appeal and provide weather protection. Inside, they may install interior trim, such as window sills, moldings, or jambs, to create a polished look that matches your home's interior design.

Clean-up and Inspection

And you’re done! Once the installation is complete, the installation team will clean up the work area, removing any debris or packaging materials. They will also perform a final inspection to ensure that the window is properly installed, operates smoothly, and meets your expectations.

Easy, right? By following these simple steps, you can have a clear understanding of the replacement window installation process. Remember, while it's possible to install windows yourself, it's best to hire professionals for a seamless and efficient installation.

Replacing your windows is an investment in your home that improves energy efficiency, comfort, and the look of your space. Get started today and bring new life to your home, schedule a free, no-obligation consultation.
