"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, 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.

Common problems include leaks, broken glass, and damaged frames. Regular maintenance prevents extensive damage.

The most affordable way to screen in a porch is to add a base track system to an existing wooden frame. The whole process should cost around $2,000 for supplies, depending on the size of your porch. It’s much pricier to build a screened-in porch or sunroom from scratch—and you’ll probably need to hire a contractor for a project like that.

Yes, if you have ventilated skylights, you can install insect screens on them. Insect screens for skylights cost $10 to $50 each, depending on their size and quality. Most pros highly recommend insect screens for ventilated skylights because they keep pests outside of your home while allowing fresh air inside.

The average cost to screen-in your patio ranges from $2,000 to $4,000. How much you spend depends on the size of your patio, the materials used, and construction complexity. Some patio screen room kits are easy to DIY, but you may need to hire a local screened-in porch builder and obtain permits for more complex designs.
