"I highly recommend Windo-Well Cover Co. They were here when they said they would be, came prepared do the job even if it rained, and went above and beyond by cleaning out the window well before installing the cover. I am happy with the look of the cover, but am especially pleased with the strenth and durability of the cover. We will use them again to cover additional window wells."

"CJ Construction reconstructed a bridge that I need to go over a creek so I can get my riding mower to the back of my property. He was friendly, efficient, professional and did this unusual project at a good price. He was very thorough and made the bridge stronger and better than it ever was. I would hire him again for any project he was willing to do. No mess and considerate of property. I would hire Jeff again without even looking for another company."

"Hired to replace 2 window screens on the second story of our home. Val found another one that needed replacing, and he did that one too, for no additional charge. He also fixed our kitchen light so that it stopped blinking when we first turned it on. Friendly, courteous, punctual and professional. Will be hiring again."

Window Door Contractors FAQs, answered by experts

The screen on many screen doors is held in place by screen spline. Screen spline is typically a thin vinyl tubing that fits into the groove of the door’s frame and holds the screen in place. To install the spline on a screen door, you’ll need a spline roller—a tool that presses the spline and screen into the door’s narrow groove. Note that old spline can crack and break, so replacing your screens is a good time to replace the spline, too.

Many kinds of window screens, such as solar screens, are designed to reduce the amount of harmful ultraviolet rays that pass through them and enter your home. The materials typically have UV-blocking properties. However, they may not completely eliminate all UV rays from passing through your home. Different window screens are designed for different purposes, and not all are designed to block or reduce UV rays. Do your research to make sure you’re getting the type of window screen to suit your needs.

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.

Typically every 10-15 years or whenever they show signs of wear and tear.

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.
