If you're looking for hardware replacement parts for Pella doors, then don't despair, you don't have to run out and buy a competely new door! To replace a hardware door part instead of saying, "oh this is broken, I better go out and buy a new door" is a much better way to go. It means less strain on the environment if you can use what you have a little longer, and it also will be cheaper for you. Example of some of the door parts which could replace if they broke down would be door handles, locks, sliding door handles, multipoint locks, hinges, flushbolt systems and more.
Over at Pella's website they list all of these replacement parts, however you can't buy things directly from their site, so what you need to do is go someplace that sells Pella products. Lowes is one example of stores that carries Pella doors and windows, so they would be the first place I would check out if I were looking for a special part. In some cases you might have to order something specific, since they probably don't carry everything in stock. Another option would be to check with your local general contractor since if they work with Pella products, then they should surely be able to order replacement parts. Perhaps the easiest thing to do would be to just talk to the people that installed the door in the first place, however if the door was there when you bought the place, or you installed it yourself, that's when you better start looking around.
One thing however that you shouldn't ignore, is going with another brands. Just because you have a Pella door doesn't necessarily mean that you have to go with a door handle of the same manufacturer. As long as you get the size right, you can often just go with another brand, and in most cases that will work out very well, and it might even be cheaper in the end...
