Remove Old Windows

For a seamless transition into the new windows, the old windows are removed and a multi-point inspection of the window rough opening is conducted. This inspection step ensures that any structural issues like water damage, termites, or framing issues are addressed before the new windows are installed.



Install New Window Frames

In the last stage of upgrading your home, we will install new windows. Our skilled crew works meticulously to frame them in a level and water-tight manner. We then finalize the installation by trimming out the windows, providing a flawless finish that will give your home the stunning look you have been looking for.

how to select your new windows

The 4 Part Window Selection Process

1. Measure the Area Where You Want to Install Your New Windows

When it comes to selecting windows for your home, there are a few crucial steps you need to follow to ensure that the end result is both functional and aesthetically pleasing. The first step is measuring the areas where you want to install your windows. Take note of the size and shape between the walls and ceilings and any architectural obstructions that may affect the window area. 

2. Narrow Down Your Preferred Window Style

When it comes to windows, selecting the right style is crucial. Need privacy in your bathroom with some ventilation? Consider an awning or hopper style window. Looking to bring in natural light for a large living room? Opt for a large fixed frame window. 

Want to enjoy a view while getting some air in your kitchen? Check out a large sliding window over the sink. With so many options available, we realize that making the right selection can be stressful.

To help we've created a helpful window style guide to assist you in selecting the perfect fit for your needs. Take a look at the different styles and find the ideal window for your application.
