Energy-Efficient Replacement Windows

What makes a window energy efficient? If your windows don’t already have insulating features, they’re likely allowing warm air to move freely to and from your home—which can affect your indoor temperatures. This is an occurrence called thermal transfer, and the replacement windows we install are designed to minimize it. They feature dual-pane glass systems with argon gas fills between the panes to create a layer of insulation that prevents thermal transfer, and their low-emissivity coatings also protect your home’s interior and furniture from harmful UV rays.

You've Got Options

We offer a large collection of styles, shapes, sizes, and colors. You can count on our experienced team to help you find the right windows for your needs, budget, and style.

Double Hung Windows

Double hung windows are a popular choice for any style home. They feature a top and bottom sash that slides up and down to provide two levels of ventilation. The inward tilting sash makes them easy to clean.

Single Hung Windows

Leahi offers custom single hung windows with a wide range of hardware finishes, colors, and sizes for you to create the perfect window for your home.

Slider Windows

Sliding windows glide open horizontally along a track for easy operation. The 2-lite slider window has two sliding sash while the 3-lite slider offers two sliding sash on each side of a fixed picture window.

Casement Windows

With casement windows you can enjoy expansive views, with lots of natural light and full ventilation. Their weather-resistant design delivers superior energy efficiency which can help improve interior comfort and reduce energy costs.

Awning Windows

Awning windows are hinged at the top and designed to open outward with the turn of a handle, providing additional ventilation and light. Use them in combination with stationary windows to create a beautiful focal point.

Picture Windows

Picture windows, also known as fixed windows, offer expansive views and abundant natural light. They are inoperable windows, meaning they do not open. Fixed windows are versatile and can be used alone or in combination with other window styles to create an eye-catching focal point.

Geometric Windows

We offer shaped windows designed to highlight your home’s design, create a focal point, and add more natural light. Our geometric windows are available in many specialty shapes including octagon, triangle, circle, half-round, quarter-round, and more.
