"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

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.

There are a number of ways to secure windows. You can add motion detectors or window sensors to detect movement and impact or change the window locks to make them stronger. Some of the ways you can secure windows are much like how you secure a home: closing the curtains at night and setting up security cameras outside so you can monitor your property even in your absence. 

If you’re not keen on using a traditional doggie door, there are some alternatives. One popular option is a solid, insulated door that you can lock when you’re out of the home for added security. You can also opt for a doggie screen, which you can lift and lower to allow your pooch access to the outdoors. These are a bit more convenient to use than a regular exterior door, although security could be an issue. You can also install a screen door with a small opening for your pup to prevent bugs from coming inside as your dog exits.

You can trim an overhead garage door screen to fit your garage door opening. This is a particularly helpful hack if you have an irregularly sized garage door opening but are still interested in installing a garage door screen to keep pests and debris out. Trim the garage door screen carefully to avoid unsightly edges or an uneven fit.

Professionals ensure repairs not only fix current problems but also prevent future issues, improving efficiency and aesthetics.
