I bought a new-construction home in July 2010. Contractor installed a therma-tru front entry door. We had no problems with the door until about a month ago. We had a very heavy thunderstorm with gusty winds. The wind blew the rain up under the 4'-deep porch/covered entry. Water was pouring inside the house from where the bottom lock-side corner of the door was not contacting the weatherstripping tightly.
The next day I started looking at the door and found that the contractor had not installed the door properly. You could see daylight coming in around the bottom corner of the door. They had not installed the corner pads where the jamb meets the adjustable sill, among other things.(more later). I watched therma-tru's troubleshooting video and tried to address some of problem areas. I installed the corner pads, trimmed the bottom of the weatherstrip appropriately, and adjusted the threshold cap. I adjusted the lock/latch plates so the door would shut a little tighter. I thought I may have gotten the leak taken care of.
Last Friday, however, we had the same type of thunderstorm again. We still had water coming in the same spot. I called the builder, but he blew me off. He said the door will flex if it's windy and let rain in. He said to get a towel and put it up against the door if there's a storm. He said get a storm door, blah, blah, blah.
Now, I'm gonna see if I can take care of this myself. I pulled my level out and did some checking. The opening is square and level. Looking at the door from the front, the jambs are plumb left to tight. The lock side of the jamb is plumb front to back. The hinge side, however, is out of plumb front to back by slightly over 1/8" in 4'. Therefore, the door, when it meets the jamb on the lock side is almost 1/4" more loose at the bottom than the top.
How does one go about fixing this? Do I need to adjust the hinges where they meet the door frame, or where they attach to the door? Is there a better way that I 'm not thinking about?
Thanks in advance. BTW, this wouldn't be such a big deal if we didn't have a hurricane bearing down on us right now.
