Exquisite doors

The vinyl patio doors that we offer are one of the many reasons why people choose the Window Design Group. Diamond Bar homeowners opt for our vinyl patio doors because, just like many Californians, they want to enjoy the outdoors in style. These doors are easy to maintain and can endure any weather.

If you want to add even more sophistication to your Diamond Bar home, you should opt for our popular and chic French doors, which can be installed indoors or out.

Window shutters that fit any lifestyle

The Window Design Group offer lavish interior window shutters that are designed with your budget and lifestyle in mind. They are customizable for your personal preference. Do you want automated plantation shutters that can open or close on a timer? We offer that. Do you want to manually operate your interior window shutters? We have more traditional, less high-tech shutter options for you as well.

Our window shutters allow you to control exactly how much natural light you want to enter your home, and they also give you control over when and how much privacy you desire. They come in a wide range of colors and styles to match any interior. A lifetime warranty comes with our composite shutters, which are beautiful and will never rot. Our rich Basswood shutters are made of all-natural wood, and they can endure all weather conditions without wearing down.
