"My overall experience was wonderful! Beginning with Chris, my sales rep, to the young men who came to conduct measurements and go over logistics with me. They took their time and answered all my questions. The installation crew were courteous, professional and friendly. At end of installations, the project manager made sure that I checked all aspects of the windows, from hinges, to opening and closing and testing for any draft. He and his crew also cleaned up after themselves. And let's not forget Diana (my new bestie), who kept me abreast of project with updates. Truly a great experience!!!! I highly recommend and will conduct any future door, window or sliding installation with Ecoview."

"The professional (Mitch) tackled a difficult job. These were heavy patio doors, installed over 25 years ago, with damaged and worn tracking. They are now sliding easily and more securely with a new, secure lock. He is now putting a new lock on our front door. He is reliable, efficient and extremely competent."

Window Door Contractors FAQs, answered by experts

Yes, you can replace the screen without removing the door in most cases depending on the frame holding the screen. Doors with removable spline and screen frames make it a snap to replace the mesh while the door remains in place. The best part is that it’s a simple DIY project requiring a few tools in addition to the screen material.

Window screens can take anywhere between 10 minutes and an hour to replace, depending on the complexity of the replacement and the accessibility of the window. Replacing the screen inside an existing frame normally takes longer than replacing an entire screen, frame and all, if you purchase a prefabricated screen already mounted on the frame.

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.

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. 

Many windows carry warranties from the manufacturer or installer that may cover the cost of repairs for a fixed amount of time. When installing or replacing windows, ask about any applicable warranties, what kinds of damage and repair they may cover, and what the procedure is for making a warranty claim.
