Do not have windows installed if there is a chance of snow.
My windows were installed on 2/17/15. The windows look good, they did a nice job installing them ---by looks. The day my windows were installed it started snowing , I think they rushed to install them and did not insulate around the window frame. My old windows the seals were bad and we had drafts cold air around windows.----MY NEW WINDOWS STILL HAVE DRAFTS. The curtains move like the windows are open---AND THE ARE CLOSED AND LOCKED!! . I hear my neighbors more now, with the new restorations windows closed and locked than i did with old windows . Called and stopped in office at least 4 or 5 times told someone going to come out and insulate around windows?? And a couple rips in screens I drop them off at office, still waiting for them to get repaired.
