Energy-Efficient Windows

Are you considering replacing the windows in your Seattle property? Opting for new energy-efficient windows not only enhances comfort in all weather conditions and improves the property's appearance, but it can also yield serious financial benefits.


Beyond saving money on lower energy bills annually, the introduction of federal tax credit incentives and rebates can provide substantial financial returns immediately. This means you could receive thousands of dollars back after upgrading to high-quality windows.

Other Window Types

1. Double-hung windows:

With two movable sashes that allow for ventilation from the top or bottom, these are the most popular window type. They can be installed almost anywhere, providing excellent ventilation and ease of use.

2. Casement windows:

Casement windows are hinged on one side and swing open like a door. They provide excellent ventilation, are easy to operate, and look beautiful.

3. Bay windows:

Bay windows consist of three windows that project outward from the home. They provide a panoramic view and can enhance the aesthetic appeal of a room.

4. Picture windows:

Picture windows are large, fixed windows that provide an unobstructed view of the outdoors. They are ideal for rooms that require natural light but do not require ventilation. While these windows are luxurious, they do come with a higher price tag.

5. Slider windows:

Slider windows slide horizontally along a track, providing easy operation and allowing for plenty of natural light. They come in extra small sizing for basements and showers, too.

6. Awning windows:

Awning windows are hinged at the top and open outward. They are perfect for areas that require protection from the rain - you can open them on a rainy day without worrying about water coming inside.


How Often to Replace Windows

How often you replace your windows depends on the quality of the windows, the materials used, and the climate in your area. Typically, windows can last anywhere from 15 to 30 years. However, if you notice any signs of damage, such as cracks, leaks, or drafts, it may be time to consider replacing them.


If your energy bills have increased significantly, it could be a sign that your windows are no longer efficient and should be replaced. It's best to consult with a professional window installer who can assess your specific situation and recommend the best course of action.

Can I Install New Windows Myself?

While window installation may appear to be a simple task, it is actually a detailed and meticulous process. It is important to ensure that the windows are installed correctly, with precise measurements, level, and square positioning.

Even a small mistake or mismeasurement could result in the windows being rendered useless or even causing damage to your home. Therefore, it is recommended to work with a professional window installation team to guarantee a safe and successful installation process.
