Condensation on metal door
 
Hi, i'm really hoping somebody on this forum can help me!

I moved into a rented flat in September - but since the weather has got colder I have had some really bad problems with condensation and resulting mold.

Turning the thermostat up has fixed most of the condensation - apart from the metal door in the bedroom leading to the outside. The frame is very cold and gets damp extremely quickly, I dry it out and it's wet almost straight away.

Is there anything I can do to the door frame to stop it from getting so cold?

Thanks a lot,
Jon

Condensation happens when warm, moist air hits something cold. If you have high humidity, do whatever you can to lower it, ie, run an exhaust fan (esp when making excess water), and/or run a dehumidifier. Approx 40% relative humidity is about right for health. If possible, insulating the door w/ foam on the outside may help; if the inside is warmer, it won't condense as much.

Is there a pattern to the condensation? Around the perimeter? Middle of the door?
If around the edges, install weatherstripping around all 4 sides. If in the middle, as previously ststed, the humidity is too high in the house.
What sort of heat do you have?

Ron: good points. I should have asked "where is it". j

Thanks for the replies.

When I check back after drying it the condensation seems to form from the bottom up. The sides are damp too aswell as the centre between the two panes of glass - but the top seems unaffected and the glass is fine.

check your weather stripping, as suggested. i suspect the top seems fine because air is going out there. either way, seal. good luck. j
