    Poor follow-up and execution. Previously had a good experience with window installation but recently had new doors installed. The installation appeared to be quick and easy but the installer was unable to use previous hardware that we were told could be used at time of sales consultation. Installer drilled a hole into the door and left it just filled with caulk. Used old hardware from another door as a temporary fix and said this would be resolved ASAP. I received no follow-up and it took nearly a week to get a call back. They then said they couldn't get a service tech schedule until 2 weeks later. This is inexcusable. I found a screw that would be long enough to put my hardware back in but now I find out that the hole isn't even in line with where it should have been. I would have chosen new hardware if I knew this was going to be an issue. Hardware compatibility should have been discussed at time of sale. The installer should have known before drilling a useless hole in a new door. We were not informed of this until it was too late. Now I am left with a door with a hole drilled through it and no door knob. I now will need a whole new door to fix this error.

    Quick friendly and efficient crew. Replaced 10 doublehung windows. Cleaned up and gone in 2hrs 40 minutes. The only way it could have been better is if they would have rehung the curtains and blinds for me. (Just kidding 😂 )

    This is the second home where I installed windows from Window World. The sales and installation process is always easy and professional. I would definitely use them again.
