"They did a good job especially considering how brittle my old siding had become over the years. I’m pleased with their work and the price was right. I plan to hire them to do a couple more small jobs that I’m to old to do myself."

Window Door Contractors FAQs, answered by experts

Screen doors have a positive ROI because of their safety features. They add protection from debris, critters, and, depending on the material, even heat. However, storm doors are better than screen doors when it comes to overall protection.

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.

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.

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

The steps to replace a retractable screen can vary, but these are the general steps: First, remove the screen cover to expose the screen mechanism and remove the clip that holds the screen in place. Next, depress the end of the screen mechanism so it releases from the door frame. Take your new screen and fit one end into the frame. You may need to rotate the mechanism to engage the spring before inserting the other end into the frame. Finally, pull the screen down the length of the door’s opening and lock it in place with the clip.
