Our Top 5 Window Options

double hung windows

Double-Hung Windows

Popular and Highly Effective

Double-hung windows consist of two sashes, each of which can be opened for maximum ventilation and airflow. Double-hung windows are very popular: they are a versatile, easy-to-use window that is a great fit for almost any style of home. These are arguably the most popular of all of our window types, but why? The reason is simple: you get a high performance product that’s also low maintenance. With their unique features, you can open double-hung windows from the top or the bottom for extra versatility in bedrooms and other rooms in your home.

casement windows

Casement Windows

Create Your Own Cross Breeze

Casement windows are excellent for ventilation and airflow, as the entire window swings open like a door via hinges on the side. They can open
a full 90 degrees, allowing you to angle them as you see fit for maximum
comfort. Our casement replacement windows from Home Guard are not only elegant, they’re supremely versatile. Our casement windows are designed to prevent drafts with a perimeter enclosed with two seals of weather strip, providing energy efficiency and comfort with some of the best ventilation out of any window in our selection.

sliding windows

Sliding Windows

Easy to Use with Great Views and
Airflow

Sliding windows use two sashes, one of which is fixed, while the other opens by “sliding” horizontally, providing you with excellent airflow and a great view. Our sliding windows use Narrowline frames and large panes so you can enjoy the best view possible with low maintenance. Sliding windows are well known for being easy to use, simple to clean, and for providing ventilation. What sets Home Guard’s sliding windows apart is that they use fewer moving parts that work efficiently and are lower maintenance for more durability and longevity.

Picture Windows Provide
Picturesque Views

Picture windows do not open, but they provide a clear and unobstructed view of what’s outside. They come in a variety of sizes and can provide you with a picturesque view of your exterior. Picture windows are unique among our selection because they lack the ability to open—but don’t let that fool you into thinking they’re inferior, as they bring beauty, security, natural light, energy efficiency, and stunning sights to your home. The lack of moving parts also means that picture windows are essentially maintenance-free and extra durable.

bay windows

Bay Windows

Panoramic Views and a Stylish
Look

Bow windows consist of at least four windows that are joined together. Like
bay windows, bow windows extend outward, moving beyond the walls of the house. Bow windows also provide an excellent view from the inside, while simultaneously looking stylish from the outside. Our replacement bow window features three to five windows that extend in a more rounded, less angular curve. With the ability to be fully customized to suit your needs, our bow windows bring even more character to your home, along with natural light and excellent airflow.

RJW people are very professional, very caring for the property. They listen, and then they do. And do perfectly. And until you are satisfied, they don't leave. I don't think I have dealt with this level of professionalism before. Really 10 stars.
