    I had a contractor caulk all the windows and it really made a difference in the winter time. I am sure I get better energy efficiency now that all the windows got a new caulking and no more cold drafts either. In the summer with the air conditioner running, I am not sure but I would think I am not losing any more air to the outside now which is nice.

    I purchased a Toll Bros home, paid extra for south facing French doors. What they did not tell me, aside from their workmen not knowing how to install front or rear doors, was the fact that one should not install French doors facing south. They will leak. Any suggestions as to how to stop a mini flood?

      Hi Stuart,

      There’s no restrictions when it comes to positing French doors that we are aware of.

      Regardless of the location, the door itself should not leak when it is exposed to outdoor elements. All patio doors, including French doors include seals that are positioned and designed to prevent direct water intrusion.

      If you think that the doors were installed incorrectly, I would invite you to take photos of the door/trim around the door and post it on the Home Depot Forums…One of our How-to experts will help you out.
