"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

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.

Yes, adding windows adds value to a brick house. Homeowners don’t shy away from more natural light and an opportunity to get fresh air. Adding a window is particularly beneficial if you live in an area with good weather for much of the year or if your home has a nice view. Keep in mind that many older brick homes have historic wood windows that add to the charm of the house. When you install a new window in a brick house, you’ll want to find one that matches the aesthetic of the existing windows.

While windows increase a home’s value, how much they increase it can vary. It depends on the age of the home and the type of windows. You can expect about 70% to 85% return on investment (ROI) when adding a window to your home.

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.

Most solar screens last 10 to 15 years, depending on the material quality, exposure to weather, and the level of maintenance. High-quality materials and regular cleaning can extend their lifespan, while harsh climates or neglect may shorten it. Routine cleaning, inspecting for damage, and avoiding harsh cleaners can help extend the lifespan of your screens.

Window screens are available in several standard sizes. Common dimensions include 24 to 36 inches wide by 36 to 48 inches tall, as well as sizes like 18 by 14 inches and 20 by 20 inches. These often correspond to standard window sizes, such as 2 feet wide by 3 feet tall or 4 feet wide by 6 feet tall. Screens are also sold in replacement rolls to accommodate various dimensions. It is always best to measure your windows for accuracy before a repair or replacement. If your windows are a non-standard size, you will likely need to order custom screens, which can increase the cost. However, a screen does not necessarily have to fit the entire window, so you may be able to use a standard-size screen even if your window is slightly larger.
