Replacement vs New Construction Windows: What’s the Difference?

When it comes time to replace or upgrade the windows in your home, you’ll need to choose between replacement windows and new construction windows. Replacement windows are designed to fit into your existing window frame, while new construction windows require the removal of your current window frames and the installation of an entirely new frame system.

Installation Requirements

The main difference between replacement and new construction windows is how they are installed.

Replacement windows can be installed directly into your existing window frame, so installation is usually quicker and less invasive. New construction windows, on the other hand, require the removal of your existing window frames. Installation includes building an entirely new frame into the wall opening, so it typically takes longer and requires minor renovations.

Energy Efficiency

In terms of energy efficiency, new construction windows generally outperform replacement windows. Since new construction windows are installed with a new, tightly-sealed frame, they tend to provide better insulation. They can significantly reduce air infiltration and improve the overall energy efficiency of your home. While replacement windows can still provide energy savings over older windows, the efficiency is often not as great as with a new construction window installation.


Not surprisingly, new construction windows tend to cost significantly more than replacement windows. The additional time, labor, and materials required for removing the existing window frames and installing the new frames lead to a higher price point. For homeowners on a budget, replacement windows can be a more affordable option to gain improved functionality, efficiency, and aesthetics. However, new construction windows may prove a better long-term investment for both comfort and home value.

In the end, you must weigh the pros and cons of replacement and new construction windows to determine what makes the most sense for your needs and budget. Either option can provide a worthwhile upgrade, so take the time to make an informed decision.

Key Factors to Consider When Choosing Between Replacement and New Construction Windows


One of the most significant factors to consider is cost. Replacement windows are typically more affordable since the window frame and structural components are already in place. New construction windows require creating an entirely new window opening, which can increase costs substantially. If budget is a concern, replacement windows may be the more practical choice.

Energy Efficiency

New construction windows offer the opportunity to choose extremely energy efficient options since you have more flexibility in the window size and framing. Modern new construction windows can achieve significantly higher energy efficiency ratings which can lower energy bills and improve the comfort of your home. For the energy conscious homeowner, new construction windows may be worth the added investment.


For many homeowners, the appearance and style of the windows is an important consideration. New construction windows provide more flexibility to change the size, number, and configuration of windows in your home. This allows you to dramatically alter the look and curb appeal. Replacement windows are limited to the existing window openings, so they typically do not provide the same opportunities for major aesthetic changes.

Light and View

If you want to increase the amount of natural light in your home or improve your outdoor views, new construction windows are likely the better choice. They give you the freedom to add more or larger windows where there were none previously. Replacement windows are confined to the current window openings, so they typically cannot significantly change the amount of light or alter views.

In summary, replacement and new construction windows each have their advantages and disadvantages. Carefully evaluating factors like cost, energy efficiency, appearance, and light can help determine which is the best option for your unique needs and priorities. With proper planning and an experienced installer, either replacement or new construction windows can be an excellent choice to improve your home.

Cost Comparison: Replacement vs New Construction Windows

When considering replacement or new construction windows for your home, cost is often a driving factor in the decision. Replacement windows are typically more budget-friendly since they are sized to fit your existing window frames. New construction windows, on the other hand, require creating an entirely new frame and installing the window, which can increase costs.

Materials and Efficiency

The materials you choose for your windows will significantly impact the price for both replacement and new construction options. More energy-efficient windows, like triple-pane windows, will be more expensive than standard dual-pane windows, though they can lower your energy bills over time. Similarly, higher-end framing materials, like vinyl, wood, or aluminum, tend to cost more than basic materials. Consider how important energy efficiency and material quality are for your needs and budget.


Installation fees will also vary between replacement and new construction windows. Replacement windows are often simpler to install since your contractor can use the existing window frame. Expect to pay between $200 to $500 per window for a professional replacement window installation. New construction windows require creating an entire new frame and installing the window, which typically ranges from $500 to $1,000 per window or more, depending on the size and number of windows.

Additional Costs

Other costs to keep in mind include permits, disposal of old windows, and trim or siding repair. Permits are typically required for new construction windows but not replacement windows. You will also need to pay for the disposal of your existing windows if doing a replacement, which can cost $50 to $100 per window. New construction windows may require repairing or replacing trim, siding, or stucco around the new window openings, adding several hundred to over a thousand dollars to the total project cost.

By evaluating your needs, priorities, and budget constraints, you can determine whether replacement or new construction windows make the most financial sense for your situation. Replacement windows offer a more budget-friendly solution while new construction windows provide higher-quality results. Compare estimates from contractors to find the right balance of costs for your home improvement goals.

Aesthetics and Design: How Replacement and New Construction Windows Differ

Replacement windows are installed in existing window frames, so they must conform to the shape and size of your current windows. New construction windows, on the other hand, are installed during building construction or renovation, so they can be custom-sized and shaped.

Window Styles

Replacement windows typically offer a more limited selection of window styles since they must fit your existing window openings. The most common styles for replacement are double-hung, casement, and slider windows. New construction windows provide many more style options, including bay windows, bow windows, garden windows, and custom shapes. You have the flexibility to choose windows that enhance your home’s architecture and design.

Window Frames

Replacement window frames are also usually limited to materials that fit standard window openings like vinyl, aluminum, and wood. New construction windows can utilize any frame material, including more high-end options like wood, aluminum-clad wood, and fiberglass. These frames often provide superior insulation and durability.

Glazing Options

While replacement windows may offer double or triple-pane glazing for improved energy efficiency, new construction windows provide the opportunity to choose specialized glazing for sound control, UV protection, security, or high-impact resistance. Glazing can also be selected based on the window’s orientation to maximize solar control and visible light transmittance.

trim and Accents

New construction windows allow for custom trim, sills, and accents that seamlessly match your home’s style. Replacement windows typically lack these custom finishing touches since they must utilize existing window trim. Exposed sashes and frames can detract from your home’s curb appeal.

In summary, while replacement windows serve an important purpose in improving the function and efficiency of existing windows, new construction windows offer superior flexibility and design options to enhance your home’s architecture and achieve your aesthetic vision. By considering both the advantages and limitations of each option for your specific needs and goals, you can make the choice that is right for your home.


When faced with the choice between replacement or new construction windows for your home, it is crucial to thoroughly evaluate the advantages and disadvantages of each option.

Frequently Asked Questions About Replacement vs New Construction Windows

Do replacement windows require a contractor?

Yes, replacement windows typically require a professional contractor for installation. Replacement windows are designed to fit into existing window openings, so installation requires removing the old windows and securing the new windows in place. This often involves tasks like installing window trim, ensuring proper sealing and insulation, and connecting the windows to your home’s frame. Unless you have experience with window installation, it is best to hire a licensed and insured contractor.

Do new construction windows require a contractor?

New construction windows also typically require a contractor for installation, especially if they are being installed in an existing structure. New construction windows are designed for installation during the building process, so adapting them for an existing home requires professional skills. The contractor will need to create proper openings, ensure structural integrity, and install the windows so they are secure, sealed, and provide adequate insulation. Some homeowners do choose to install new construction windows themselves to save money, but this requires significant DIY experience and knowledge.

Are replacement windows more expensive than new construction windows?

The cost difference between replacement and new construction windows can vary depending on factors like the type of windows, materials, brand, and contractor rates in your area. In general, replacement windows tend to be slightly more expensive. This is because replacement window installation requires additional work like removing the existing windows. However, replacement windows can still often provide cost savings over time through improved energy efficiency. New construction windows may have a lower upfront cost, but provide less opportunity for energy savings if your existing windows are very old or inefficient.
