The Twin cities representative of Window World install 4 double hung windows in our home last fall. The wind was coming throught the windows and we had the company out to check them.
They recaulked (huge amounts) around the windows but the leakage did not improve. In the winter months yoou could see the curtains move. The locking mechanism failed so the windows would not stay shut. The windows are the cheapest pieces of junk on the planet.
Stay away at all cost. Warranty is not worth the ink used to write it.
They have been out 4 times and the windows still leak. We will be removing them and replacing them with complete windows because during install they damaged the frames.
