"Never came to the door the morning they began. Just jumped on the roof and started pounding. The job did get done and the work appears good. Early to tell because the weather hasnt been warm enough to even seal yet. Workers left ketchup packets in the yard."

"We had cracks in the dyed mortar of the bricks above our garage. Grady took the time to match the color, even with the color having aged 10 years, and you would not even be able to tell that there was new mortar. If your project is anything like ours, you will not be disappointed."

"The installation was efficient and satisfactory; however, I would have appreciated it if the sales rep, when meeting with me at my home and going over the options, would have pointed out that the color of the window frame would not match the color of surrounding wood."

"We were installing all new windows in our home, 12 total. Chance, their crew leader arrived with the truck containing the windows and immediately did an inventory as the crew was arriving, and making sure all windows and tools were on hand. Chance advised they would have all windows installed in one day. Based on the number of the crew they made fast work of the installation. Each worker knew the task at hand and completed all the installation and clean up by end of the day. We did a walk around with Chance looking for any issues or problems we could find. Chance and crew advised their office on the completion. The crew did a great job and every window was installed correctly. I would recommend their company, crew and sales people. Modern Windows were the only ones that wanted to come to our region of NY and had a Sales Person on the road the next day."

Window Door Contractors FAQs, answered by experts

Most windows last for 15 to 30 years, depending on the frame material and the glass quality, but most will require repairs during that time. Windows gradually lose efficiency, so it’s usually best to have a window repair technician inspect and service your windows every five to 10 years. You should also repair your windows if you experience the following:

  • Leaks

  • Drafts

  • Difficulty opening or closing

  • Sudden increases in heating and cooling bills

  • Outdoor noise becomes more audible

  • Signs of physical damage

For most common repairs, a professional window repair service can fix a window in one to three hours. However, replacing window frames or repairing a large, multi-pane window will likely take longer to complete. For comparison, a window installation or repair professional should be able to replace up to 15 windows per day.

Some hardware or specialty window stores in your area may repair damaged screens, but it’s less time-consuming, more convenient, and potentially more affordable to hire a screen repair technician to come to your home to do the work on-site. The screen technician will have the tools and experience to get the work done the same day, and they can inspect other screens while there to help avoid repeat repair costs in the future.

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.

While the telltale signs can vary for different types of screen doors, it may be time to learn how to install a screen door if you're noticing rotting, warping, or splintering accompanying the sagging. If you’re unsure whether to replace a sagging screen door, consult a local screen door pro for an inspection and final decision.
