Condensate leaking out of doorknob
My daughter just moved into a new home and both exterior doors are
leaking condensate out on the cold side of the door. What can be done to stop this? |

Moisture enters things like doors knobs through a process of thermal pumping where alternate cycles of heating and cooling cause the doorknob to "breathe". Anything hat will break the cycle will stop the leak, keep it at a constant temp or seal it. Jimmie |

Jimmie Thanks for the help. I'll try sealing it. |

.... Thanks for the help. I'll try sealing it. You definitely don't want to prevent the moisture from getting out the outside and being trapped internally--that will simply cause even more damage than it is at present. If this is actually just condensation in a lockset cavity, I'd suggest at most a thermal break like the wall outlet covers or something on the inner side at most. If there's really liquid water running out the outside, I'd be more inclined to think there's a leak in the door skin or around the escutcheon, etc., and external rain/snow/etc. is getting in and then you're seeing it on its way back out. I'd pull the lockset and see what's actually happening; I'm having trouble thinking simple condensation would do it as there's not enough volume of air it would seem unless there are large leak paths and there's an extremely high humidity issue. -- |

Someone asked this question before and I found where somebody had patented a doorknob insulator. I just found a company that supplies something called "Great Grips". One of the things they do is insulate the doorknob. It may work for you. http://www.greatgrips.com/answers.html TDD |

I talked to the door company yesterday, and they said to replace the insulation around the door jamb. This doesn't make sense to me when it is a brand new door. |

Guess it's possible there was a poor installation job, but that wouldn't seem to explain condensation (assuming, again, it really is condensation and not rain/snow melt). I'm curious as to the type of door and the location and the actual quantity of moisture and where it actually is originating. I'd still think it highly unlikely condensation alone could be the source of water running from the lockset cavity out -- I could see condensation of moisture on an exterior surface from very humid outside air; I can't see sufficient leakage volume for significant moisture from the inside out. -- |

Assuming the doorknobs on both sides are hollow, I would put some sort of foam inside them...there are craft paints that "foam" when applied, but just about anything foamy should work to keep warmth from passing to the outside. |

Both doors are running water out the doorknob plates to the cold side. I noticed yesterday that there is condensate forming around the edges of the door too, but not in such large quantity as through the doorknobs. |

I noticed yesterday that there is condensate forming around the edges of the door too, but not in such large quantity as through the doorknobs. You taken the locksets out to see what's happening? I find this an incredible scenario still. I'm wondering if the doors weren't stored outside before hanging and the cladding is full of water that is the source. It just doesn't seem possible to have the amount you seem to have from simple condensation alone through an essentially closed-off 3" diameter hole. How 'bout posting some pictures on one of the hosting sites? I'd like to see this phenomenon. If it's so, I'm jealous of anywhere that has sufficient humidity to even have any condensation as we're dry beyond the pale even by our expected winter months...not to mention we're 20+F above normal w/ 30-50mph winds last few days and at least another one or two to go...far too warm too soon and we're already pushing moisture numbers lower than the '50s leaving only the '30s as as dry or drier... -- |
