Don't Replace- Insulate

Phone: 209-465-3200

We have a mid-century modern home with single pane aluminum and jalousie (Florida slat style) windows. You can imagine how poor they were at keeping out the weather, bugs and noise as a result. All of the new vinyl window products on the market simply do not fit our aesthetics. We have been very pleased with our new magnetized window covers and, because they were made to match the aluminum, we are especially happy that we did not have to compromise the look of our house. The "icing" was that we were able to solve our problem at a fraction of the cost. Thank you for the excellent product and service.

Thanks for the great job installing the window covers. I was a little skeptical, even after your demonstrations, but the results have been great. Besides the huge noise reduction, the thing I like best is the consistency of the temperature in the house. I used to feel the house getting cold before the heater kicked on. Now I don’t notice the heater working because the temperature is so much more stable. My wife especially noticed we no longer had any kind of condensation on the windows. Thanks again for the great work.

We would like to express to you our thanks and satisfaction with the window covers you installed in our home last year. The panels have exceeded our expections, being excellent in both thermal and acoustical abilities, the peace and quiet is wonderful, the easy access when we want them open and the trim blends very well in all the rooms. Also you and your crew's friendliness throughout the installation made this an entirely pleasant experience.

Have a great 2006!


We had Castle Window Covers put in our acrylic window covers throughout the house about a year ago. They have been a blessing for us, really a great fit for our needs. At first we had these neat windows installed in our larger floor to ceiling windows all across the back West facing windows. We were a little skeptical at first since these windows are really the focal point of our décor (view). We quickly saw that these look just like regular windows and sometimes I still do a double check while checking if I snapped them back on or not. We quickly realized how the rest of bedroom windows would draw in the cold air and cause a chilly draft, so we had them come back to finish the rest of the windows. Since our energy bills were killing us, I was more than motivated to see how this would help save and conserve. We were nicely impressed. Awesome customer service from the start, and they even helped us with financing. With a little extra care and attention to these windows, you can have affordable Castle Window Covers.

We are so thankful to have our window covers. Our family room faces east and there is no way to shade the upper windows. By midday the hot summer sun made the room like an oven. These window covers have made a tremendous difference in the comfort for our family. My wife now wants to have the lower windows covered so we won't need the drapes closed in the morning during the summer. They also help keep the heat in during the winter.

My home was built in 1927 and when I bought it ten years ago, I made a commitment to respect it's integrity regarding retro-modeling and repairs. Because I live on a busy street and have leaded paned windows, temperature, moisture and noise became a real issue. I could not find anyone locally who would help me with this problem. Fortunately, a friend told me about Castle Window Covers and they figured out the perfect solution for my "custom" problem. You cannot believe the improvement!
