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.

Why others have chosen our vinyl replacement windows

Unlike other companies, we do not charge our customers extra for different features and styles. We understand that everyone’s tastes and preferences are varied, and no one should have to put more money out of their pocket because they like a certain option. Every Diamond Bar homeowner’s personal taste is equally valuable. You take the wheel and tell us exactly the color you want your windows, how transparent or obscure you want them, and choose the shape you would like. We have a variety of grid patterns, limitless style choices, and infinite size options. Take your pick. You can trust our windows because they are not put up for sale until they are tested and certified for safety and durability. We also test their impact on energy conservation.

The Owner Called Me Personally!

“Highly recommend the Window Design Group in Simi Valley! To date they have completed new window installs at two rental properties for me in Los Angeles County. V.P. Christoper Margott worked with me on these projects from start to finish. Turn around time was approximately 3-4 weeks and the windows are of high quality, look fantastic and I am saving bundles on the bills! This company is fast, professional and very responsive to your needs. Check out their website as they offer many other products and services. Window Design Group has all my future business! Thanks again!”

Highly Recommended

“Great company. Had them out for an estimate only for shades at my Ventura County home, and they recommended replacing all my windows and sliders with the new energy efficient kind. Said would help on my crazy electric bill since I had those old 70’s windows. I didn’t think I could afford them, but the price was really reasonable and they let me do financing. I even got my roman shades and I love them. They installed them fast and professionally in the timeframe they gave me. I liked that they were very cognitive of my wood floors and plastered walls not getting damaged. They laid out tarps and let me know that the gaps in the windows are temporary. Meaning since I was WATCHING everything to make sure I waited until the end to start making judgements. It’s an interesting process changing out ALL windows. The windows and shades have now been installed for a few months now and everything is awesome. What a difference they make.”

Great Company!
