"It went very well! They showed up on time and addressed all the concerns I had. Jeremiah went through everything with us and was able to have it done in no time. We’ve had contractors before and they would say they would get it done by those time and it would never be done by the time they would say. We were very happy and pleased that they had it finished when they said they would. They did amazing work and I would recommend them to anyone!"

"6 month wait due to supply issues, and had to call back after install due to sloppy caulking. They did come resolve the issue promptly, and quality of the door installed is excellent."

Window Door Contractors FAQs, 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.

No, it’s not safe to leave a doggy door open. It might be more convenient, especially at night when you just want to lay in bed. However, when you leave it open, it increases the chance of other critters getting in without your knowledge. Also, it leaves your pup unsupervised for hours at a time.

If you’re not an experienced DIYer, consider hiring a local patio repair contractor to rescreen your porch or sunroom. Unless you’re only repairing a small rip or hole, this project is not an easy job. A professional can also make recommendations for materials that will work best for your porch.

Yes, you can absolutely put a screen on a casement window, and most casement windows come with screens. Unlike with a double-hung, single-hung, or sliding window, the screen in a casement window sits on the inside of the window so that the sash can freely open outward. Screens are especially important for casement windows because the large window opening the window provides leaves your home more open to bugs and outside debris than most other types of operable windows.

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.
