How To Install A New Window In A House With Vinyl Siding

September 6, 2023

Energy Windows Doors and More has many years of experience upgrading Delaware Valley homes with replacement windows, and we’re often asked whether it’s possible to install new windows without replacing existing vinyl siding. The answer to that question is yes, and with that, let’s explore how to install a new window in a house with vinyl siding that doesn’t yet need to be replaced.

DIY Projects Can Be Risky

While it may seem appealing to install a new window in a house with vinyl siding on your own, do-it-yourself solutions frequently cause more harm than good. It is best to consult with a specialist who can answer all of your questions and provide a speedy, long-term solution.

• Choose the Perfect Replacement Window

The first step in the process is choosing the right window. We recommend a high-quality window from leading brands like Andersen, Ideal, Interstate, Pella, and ProVia, and preferably a product with ENERGY STAR certification. Our company has project consultants available to answer your questions, explore your options, and help you choose the perfect window while working within your budget.

• Measure the Existing Window

The next step is to measure the window being replaced, and our window experts will perform precise measurements. We use those measurements to order a window that’s an exact fit for your home, and in some cases, that window will need to be custom-made by the manufacturer.

• Remove the Old Window and Prep the Window Area

Once your new window arrives, our team will install it, and that process is typically completed in a day. The first phase of how to install a new window in a house with vinyl siding involves removing the old window while preserving any of the exterior and interior components that may need to be reused.

After our team has removed the window and frame, we’ll be able to remove the vinyl casing. This provides an opportunity to inspect the vinyl around the window and verify its condition. In most cases, it’ll be fine, but if there is damage, this is the time to replace it. This is also the point at which our window installers will add end caps to the window sill.

• Install the New Window

The next phase of how to install a new window in a house with vinyl siding involves inspecting the window area and ensuring there is no rot or other damage. Such damage isn’t usual, but if it exists, the wood needs to be replaced, as it could undermine your new window in the years ahead.

Our window installers will then apply flashing tape and other materials in order to create a moisture barrier. Once the window area is prepped, we’ll dry-fit the new window. We’ll then fasten the window and add a new J-channel to the window frame. The finishing touches will involve reinstalling any vinyl siding and filling in the gaps around the window to deliver beautiful curb appeal.

• Test the New Window

Once the window installation is complete and our work areas are cleaned up, we’ll thoroughly test the window to ensure that everything is functioning as it should. Finally, we perform an interior and exterior walkthrough with the homeowner to ensure their complete satisfaction, and we advise them to let the window rest for 24 hours prior to heavy use in order to allow the sealants to cure.
