In this blog post, we will explore everything you need to know about new construction window installation in existing home. From understanding what these windows are, to how they differ from other types of windows to the process involved in installation, we will break it all down to help you make an informed decision.

What Are New Construction Windows?

Before diving into whether it’s possible to install new construction windows in an existing house, it's important to first understand what new construction windows are. New construction windows are designed specifically for homes that are being built from the ground up. They are typically installed during the framing stage, before the walls are finished. These windows come with a nail fin, a flange that allows them to be attached to the studs and the rough opening of the home.

New construction window installation in existing home is a process that differs from the installation of replacement windows. Replacement windows, as the name suggests, are designed to replace an existing window without the need to remove the entire frame. New construction windows, on the other hand, are installed in such a way that they require the removal of the existing window frame, making them a more involved process.

Why Choose New Construction Windows?

There are several reasons why a homeowner might choose to install new construction window installation in existing home rather than opting for replacement windows:

1. Aesthetic Appeal: New construction windows often provide a more updated look, with modern frames, materials, and energy-efficient features.


2. Improved Energy Efficiency: Many new construction windows come with enhanced insulation properties, including double or triple glazing, which can improve your home's overall energy efficiency.


3. Customization: These windows offer more customization options, allowing homeowners to choose from a variety of frame materials, styles, and finishes.


4. Structural Integrity: If your current window frames are in poor condition or have become warped or damaged over time, new construction windows can be a better long-term solution.


5. Increased Home Value: Installing new construction window installation in existing home can potentially increase your home’s market value, particularly if you are updating older or outdated windows.

Can You Install New Construction Windows in an Existing House?

The short answer is yes—new construction window installation in existing home is entirely possible. However, it is important to note that the process is more involved than simply replacing windows. There are several factors to consider, including the structural condition of your home, the scope of the project, and the necessary permits.

Here’s a breakdown of the main considerations:

1. Structural Integrity of the Home

One of the first things to assess when considering new construction window installation in existing home is the condition of the structure. New construction windows are designed to be installed into a rough opening with a frame that is free of damage. If the framing around your existing windows is in poor condition, you may need to repair or replace the surrounding structure before installing new construction windows.

In many cases, installing new construction windows will require cutting into the wall or altering the frame. This means that your home’s framing must be strong enough to support the window. If there are issues with the framing, such as rot or warping, it may be necessary to reinforce the wall structure before proceeding.

2. Window Size and Placement

Another consideration is the size and placement of the new construction window. New construction windows come in a variety of sizes, and in some cases, the window opening in an existing home may need to be altered to accommodate the new window.

For example, if you’re replacing an old window with a larger one, you may need to widen the rough opening, which could involve removing drywall or siding. Conversely, if you’re replacing a larger window with a smaller one, the rough opening will need to be resized to fit the new window, which could also require modifications to the structure.

It’s important to consult with a professional to determine whether your existing window openings can accommodate the new windows without extensive modification. The goal is to ensure that the new windows fit securely within the existing framing, without compromising the structural integrity of the wall.

3. Removal of Existing Windows

One of the most significant steps in new construction window installation in existing home is the removal of the old window. Unlike replacement windows, which are designed to fit into the existing frame, new construction windows require the entire window frame and surrounding structure to be removed.

This process can be time-consuming and labor-intensive, as it may involve cutting away siding, drywall, and trim. It’s important to ensure that the removal is done carefully to avoid damaging the surrounding structure. Once the old window and frame are removed, the new construction window can be installed in the rough opening.

4. Permits and Building Codes

In most cases, installing new construction window installation in existing home will require permits and inspections. Building codes vary by location, so it’s essential to check with your local municipality to determine whether a permit is necessary for window installation. This is especially important if you plan to make structural changes to the wall or enlarge the window opening.

A professional contractor will typically handle the permit process, ensuring that the installation complies with local building codes and regulations. This can help prevent any issues down the line and ensure that the installation is done safely and correctly.

5. Cost and Time Involved

Installing new construction window installation in existing home is generally more expensive and time-consuming than replacing windows with retrofit or replacement windows. This is because the process involves removing the old window frame, potentially making structural changes, and ensuring that the new window is properly sealed and insulated.

On average, the cost of installing new construction windows can range from $300 to $1,000 per window, depending on the size, style, and material of the window. Labor costs can also vary, but you can expect to pay anywhere from $150 to $500 per window for professional installation.

Additionally, because the process is more involved, it may take several days or even weeks to complete, depending on the scope of the project. Be prepared for some disruption to your home during the installation process.

Steps Involved in New Construction Window Installation in an Existing Home

Now that we’ve discussed the key considerations, let’s take a closer look at the steps involved in new construction window installation in existing home:

Step 1: Assessment and Planning

The first step in the process is to assess the existing window openings and determine whether the new construction windows will fit. A professional contractor will inspect the framing, walls, and window openings to ensure that the new windows can be installed without major structural modifications.

Step 2: Removal of Old Windows

Once the assessment is complete, the next step is to remove the old windows. This involves cutting away the trim, removing the window sashes, and carefully extracting the old window frame. If necessary, the surrounding drywall or siding will also be removed to expose the rough opening.

Step 3: Preparation of the Rough Opening

After the old window is removed, the rough opening will be prepared for the new construction window. This may involve reinforcing the framing, enlarging the opening, or making other modifications to ensure that the new window fits securely.

Step 4: Installation of the New Window

Once the rough opening is ready, the new construction window can be installed. The window will be placed into the opening, and the nail fin will be attached to the framing using nails or screws. The window will then be sealed to prevent drafts and moisture infiltration, and the surrounding wall will be repaired.

Step 5: Finishing Touches

After the window is installed, the finishing touches can be applied. This includes reinstalling trim, repairing any drywall or siding, and ensuring that the window is properly insulated and sealed.

Conclusion

In conclusion, new construction window installation in existing home is entirely possible and can offer numerous benefits, including improved energy efficiency, enhanced aesthetics, and increased home value. However, the process is more involved than replacing windows with retrofit or replacement models, and it requires careful planning and professional installation. If you’re considering installing new construction windows in your existing home, be sure to consult with a contractor to determine the feasibility of the project and to ensure that it’s done correctly and safely.

By understanding the steps involved and the factors to consider, you can make an informed decision about whether new construction windows are the right choice for your home. With the right preparation and professional assistance, you can enjoy the many benefits that these windows have to offer.
