Hi guys, I need to replace an old exterior door (which goes from a bedroom into the yard). The problem is, the opening is a bit too short: it's 81". I'm interested in a wooden prehung door, and the manufacturer says that the assembled height is 83". This is the door I'm considering: [url=http://www.homedepot.com/p/JELD-WEN-1-Lite-Unfinished-AuraLast-Pine-Solid-Wood-Entry-Door-with-Primed-White-Jamb-and-Brickmold-THDJW185600001/203662219?MERCH=REC-_-NavPLPHorizontal1-1-_-NA-_-203662219-_-N#.Ukt7Xoaxd3s]JELD-WEN 1-Lite Unfinished AuraLast Pine Solid Wood Entry Door with Primed White Jamb and Brickmold-THDJW185600001 at The Home Depot[/url] The installation instructions seem to suggest that the threshold is installed separately (before) the door is installed, so I'm thinking that perhaps I can cut the door and the jambs by ~2". I'm reasonably handy, but I wanted to get your opinion on whether you think this is doable, or a stupid idea. Do you see any issues with this? Thanks a bunch!

Often the threads I read on this wander off into discussions on the entire window lines of these companies. I have beat my head on the wal, I see so many pluses and minuses for each mfr. If we can keep the discussion to the fiberglass/composite lines that would be most helpful, we are pretty much set in stone on wanting that. So specifically, and we know we will pay through the nose to have composite windows, but the choices I see in this area (we don't have Milgard naywhere near us) are: Renewal by Anderson, Pella Impervia, and can do either Marvin (Integrity or Infinity, although different installers for each) If I have this correct, Infinity and Renewal are installed only, although we aren't remotely interested in a DIY anyways. Anderson and Marvin seem to be the front runners, I just found out about the Impervia, there is a showroom we will visit to look at it. We looked at Infinity once and were blown away by the looks, the company also said they would do the staining. I have the previous thread form yesterday about new vs replacement, we are still on the fence about that; we would need to do 2 of them as replacements anyways so might just do it all the same, Infinity and Renewal are both replacement only although Integrity we can do new, not sure on the Pella. Also not sure what the warranties are on each yet. As I mentioned on the previous thread we are planning on residing at the same time. We have time to decide, we are saving a boatload of money, we know this will be big bucks.
