Your Comprehensive Guide to Retrofit Windows – Save Energy and Money
Welcome to your complete guide on retrofit windows, a practical and affordable solution for upgrading your home’s energy efficiency. At SilverLine Exteriors, we believe in empowering homeowners with information to make the best decisions about their home improvements.
Understanding Retrofit Windows
First, let’s clear the air on what retrofit windows actually are.
Retrofit windows, also known as replacement windows, are custom-built to fit into the existing window opening in your home. They’re designed to replace your old windows without disturbing the surrounding trim or interior wall, making them an excellent choice for preserving the integrity of the existing building envelope and aesthetics.
The most common type of retrofit windows are vinyl windows. They are designed with a flat exterior flange on outside of the window frame. This is also known as the rebate flange. This flange covers up the old window frame, and makes the installation easy, clean and seamless with the exterior siding.

This design is quite different from the new construction frame, which has a nail-on flange. As shown in the photo here, nail-on flanges have punched holes that allow for fasteners to secure the window from the outside. However, the retrofit windows are typically fastened on the side from the interior.

The Benefits of Retrofit Windows
Why should you consider retrofit windows for your home? Here are some compelling reasons:
- Energy Efficiency: Retrofit windows are designed to provide superior insulation, helping keep your home warm in the winter and cool in the summer. This can lead to significant savings on your energy bills over time.
- Cost-effectiveness: Compared to new construction windows, retrofit windows offer a more affordable solution for upgrading your home’s windows. The installation process is less disruptive and often quicker, saving you labor costs as well.
- Ease of Installation: As these windows are custom-built to fit your existing window openings, the installation process is straightforward and fast. Whether you’re embarking on a DIY retrofit window replacement or hiring a professional, you’ll appreciate the hassle-free installation process.
- Variety: With retrofit windows, you have a wide range of styles, colours, and materials to choose from. This makes it easy to find windows that match your home’s architectural style and personal aesthetic.
Investing in retrofit windows can drastically improve your home’s energy efficiency, aesthetic appeal, and overall value. Stay tuned for more on the installation process and cost considerations in our upcoming sections.
The Process of Installing Retrofit Windows
Retrofit windows offer a straightforward installation process, one of the main reasons homeowners find them appealing. In general the process involve the following main components:
- Measurements: The first step involves accurately measuring the existing window openings to ensure your retrofit windows fit perfectly.
- Removing Old Windows: The old window sashes, stops and tracks are removed, while the original frame is preserved. This helps maintain your home’s existing aesthetic.
- Installation: The new retrofit window is then installed in the existing frame. Because they’re custom-built to fit, this process is relatively quick and uncomplicated.
- Insulation: Once the new window is securely in place, the gaps are insulated. This step is crucial for maximizing your window’s energy efficiency.
- Finishing Touches: Finally, the interior trim is reinstalled or new trim is added, and the exterior is sealed.
For homeowners who are handy, a DIY retrofit window installation can be an engaging project. However, with different existing siding on the home, you may need different types of flashing to ensure proper water shedding. To ensure the best results and maintain the manufacturer’s warranty, it might be best to hire professionals like the experienced team at SilverLine Exteriors.
Cost Considerations for Retrofit Windows
Understanding the cost of retrofit windows is an important part of planning your home improvement project. Here’s what you should consider:
- Window Quality: High-quality windows might have a higher upfront cost, but they often offer better energy efficiency and longevity. This can result in cost savings over time.
- Installation: If you’re hiring professionals for your window installation, consider their fees. Remember, a proper installation is crucial for the performance and durability of your windows.
- Energy Savings: Retrofit windows can lead to significant savings on your energy bills. Customers may also qualify for government rebates when choosing EnergyStar windows. We have a separate guide on how to maximize your window rebates.
- Home Value: New windows can improve the curb appeal and value of your home. If you plan to sell in the future, this is a beneficial factor.
In general, retrofit windows are a cost-effective option compared to new construction windows. They require less labor for installation and offer energy-saving benefits that can offset the initial cost over time.
Making an informed choice about retrofit windows for your home means considering both the initial investment and the potential long-term savings. In the next section, we’ll compare retrofit windows to new construction windows to help you make the best decision for your home.
Comparing Retrofit Windows and New Construction Windows
When planning a window replacement project, it’s crucial to understand the difference between retrofit windows and new construction windows. Let’s explore the key differences:
- Installation: Retrofit windows are installed in the existing window opening, preserving the original frame, trim, and interior. On the other hand, new construction windows require the complete removal of the existing window, including the frame, which often involves more labor and higher installation costs.
- Cost: Due to the less intensive installation process, retrofit windows are usually more affordable than new construction windows.
- Home Disruption: Retrofit windows cause minimal disruption to your home’s structure and aesthetics, while new construction windows may require significant changes, especially in older homes. If your existing home has good building envelope, retrofit may be a better option because of it’s ease of install and minimal disruption. However, if you are updating the look of your home, new construction style installation provides more flexibility.
Your choice between retrofit windows and new construction windows will largely depend on your specific needs, budget, and the condition of your existing envelope condition.
Choosing the Right Retrofit Windows for Your Home
Choosing the right retrofit windows involves considering several factors. Here’s a handy guide:
- Style: From sing-hung to casement to picture windows, there are various styles to choose from that will best fit your home’s architectural style.
- Energy Efficiency: Look for features like double glazing and Low-E coating, which can improve a window’s energy efficiency. Be sure to check out the windows Energystar rating before purchasing.
- Cost: Keep in mind both the initial cost of the windows and potential long-term energy savings.
- Installation: Decide whether you’ll take on a DIY installation or hire professionals. Remember, installation can impact the performance and lifespan of your windows.
