"Bob came out and provided an estimate which included options for completing the work. Once the work was scheduled he arrived on time and courteous, as usual. New security light of our choosing was installed in our backyard and a GFI outlet were installed in the garage in under an hour. We have used Mr. Handyman Metro East for several projects at our home and continue to use them because of their professionalism, value and customer focus."

"I used H&F exteriors to install windows in a 130 year-old historic property. The old windows were crusty and inefficient. The new windows are great, and have cut the heating and cooling bills in half. H&F and their team were terrific to work with, honest and responsive."

"Very professional and at the same time approachable. After looking at pictures of hole in siding and wall, and in person, was able to give a detailed estimate that made complete sense. Agreed with estimate and signed contract. Came out within a week and fixed the issue. Did not need to be home for any of it! Huge plus! Looks great. Will be hiring them again this year for another project. Highly recommend!"

Window Door Contractors questions, answered by experts

Yes, you can add a screen door to most door frames. The screen should be able to fit standard-size door frames, so unless you have an unusually sized door, you shouldn’t have an issue. Just make sure to properly measure the frame. When in doubt, it’s best to let a pro take care of this task for you so it’s installed correctly.

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.

Most window screens in residential homes are designed to be removed from the inside, especially with double-hung, single-hung, and casement styles. That said, some setups require exterior removal. Older homes or custom installs may have exterior clips or brackets, and sunscreens are almost always mounted on the outside. Before removing your window screen, look at how it is held in place.

Yes, professionals can enhance screen durability by using robust materials like stainless steel or fiberglass and employing advanced installation techniques. They provide reinforcement and repair services that extend the screens' lifespan while maintaining functionality and appearance.

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.
