I purchased a rear entry slab door from http://www.extrabuild.com/, and Adoor fabricated a custom frame, and reinstalled the pre-hung door.
The installer showed up on time with all the necessary tools for the job. He was very detailed with the install. He took his time, and made sure the door was perfectly aligned before he secured the door to the structure, insulated around the frame, caulked and weather sealed door. The door looks fantastic, and it opens and shuts perfectly. I can't believe how much nicer our home looks with the new door. In addition, the installer was very friendly, and he didn't mind me asking questions. Finally, if I need any more door installs, I'll be calling Adoor read more
