Purchased a beautiful pre-hung round top knotty alder front door. Model ARR662SC Knotty Alder RT Entry W/speakeasy W/clavos. Absolutely beautiful door for a total of $1,785. Upon having it installed it was very obvious the top of the door jamb was out of line with the PRE-HUNG door. There was a large gap around the top. Remember the door was purchased pre-hung. All I did was have it installed. Doors4home was advised and they contacted the manufacturer and tried to act as a go between. According to Doors4home, the manufacturer kept trying to say it was my fault. Problem is that I did not construct the door or frame or attach them. Additionally, I did not buy the door from the manufacturer, nor did I contact the manufacturer. Doors4home who I did business with did nothing. From the outside the door looks great. From the inside, there is a gap at the top. Sorry I did business with them.
