"I am very skeptical of roofing companies, or just contractors in general. I read a lot of reviews, but rarely take the time to make a review myself. I had such a great experience with Star window doors roofing etc.. that I decided to write this review. My salesman, Dennis was top notch. He was very knowledgeable, responsive, and kind, never pushy."

"We couldn’t have replaced this door with a better expert. Ryan took measurements and photos, then recommended several doors in various price ranges. We didn’t realize how many options come with storm doors. Ryan gave us some really good recommendations and helped us make a great choice. He installed the door in a half day while we were out. Came back to a gorgeous door/screen storm door combo- something we weren’t even sure could have been done to begin with. Important to know:Throughout the entire process, Ryan was responsive and easy to reach. That’s vital in a world where ghosting is the norm (unfortunately). Ryan is the expert you need for your remodeling needs. Highly recommend!"

Window Door Contractors FAQs, answered by experts

A garage door screen can be a worthwhile investment, especially if you frequently use your garage for activities like a home gym, workshop, or other hobbies. It allows you to enjoy fresh air and natural light without worrying about bugs. Additionally, a screen provides ventilation that can improve air quality when you're working with paints, varnishes, or producing sawdust.

The best option depends on your usage. For occasional use, a DIY fabric screen is a low-cost, simple solution that you can put up and take down as needed. If you plan to spend a lot of time in the space, investing in a customized, professionally installed garage door screen can help transform the area into a new hub for your household.

While the benefits of garage door screens usually outweigh the downsides, there are some cons to installing one. First off, they can be quite expensive, especially if you’re having a professional install a retracting screen or a custom size screen. Second, they let fresh air and natural light in, but they also don’t provide the same privacy from people in the neighborhood that a solid door does. As you might guess, screens also won’t insulate your garage, so they’re often not usable in colder weather.

Window screens can help keep some heat out of your home, which is one benefit of using them in summer. It’s also the reason experts suggest removing your screens in winter—so it’s easier for the sun’s warmth to filter into your home. This will keep you cozier and potentially reduce your heating bills.

Screen repair is always worthwhile, as tears and holes in your windows and door screens are unsightly and allow pests and debris into your home, rendering the screen useless. The faster you repair your screens, the faster you can open your windows and doors freely to let the fresh air in. Consider repairing multiple door and window screens during one appointment with a screen repair technician to make the investment and labor costs worth it.

Professionals clean window screens the same way a homeowner can—by removing the screens and cleaning them with a sponge. A window cleaning pro may come with better equipment, like a high powered wet/dry vacuum or pressure washer to speed up the process and achieve a deeper clean.
