I'm looking for some general information about condensation on windows.

What is normal? What signs should I be looking for that there may be a problem?

I just bought my first home this July. The building is 10 years old. In one bedroom I see alot of moisture (to the point it begins to drip down the window) in the morning. How do I go about solving this problem?

I walked around the building and inspected the windows. I noticed that there is no calking around the outside casing, it is vinyl siding. should I calk ?

thanks

Where are you seeing moisture?

Inside (living side) of the windows?

Outside of the windows?

Between panes?

Where do you live?

Do you have a dirt basement or crawlspace floor?

Do you have basement water problems?

Does this moisture occur year round or seasonally?

I'm seeing moisture on the inside (living side) of the window.

I live on the shores of Lake Michigan.

I just bought the home this July, so I can't tell you if it is seasonal. It has a crawl space that I just insulated and I doesn't appear to have any water problems, it was damp and humid this summer but, we had ALOT of rain this summer ( one of the ten wettest summers in the last 100 years.) I put fresh vapor barrier down on the sand and put r-19 inbetween the floor joists along with wrapping the heating ducts.

The moisture on the window was there before I insulated and it is still there. It is only this bedroom window that is doing it. It is double pane window and doesn't appear cloudy when dry.

What did you cover the crawl space sand with?

If 6 mil plastic sheeting, did you tape and seal all edges where the seams overlap and tape to the foundation walls?

Foundation walls may still need to be sealed inside to prevent water vapor from entering thru the ground.

Moisture could be from rising damp from the basement even if you did cover the floor but not seal well either walls or floor..

Check your bathroom vents and dryer vents if any. Make sure they are running to the outside of the house not just into the attic or elsewhere.

Since this only occurs on a single window check to make sure this isn't a leak above the window itself showing up as wet on the glass.

Is this a window with an AC unit? Near one? Near an AC vent?

May need to run a dehumidifier.

I used 6 mil on the sand, I did tape the center seam with a type of tape that you can use on Tyvek. I did not tape the plastic to the wall, although I did leave a good foot of plastic. I figured tape wouldn't stick to the cinder block walls.

I have central air, so no window aidr conditioners. when I did the insulation I made sure the dryer vent was connected properly. But I will check the bathroom venting that is in the attic.

I did purchase a dehumidifier and it is in the crawl space.

Question: what tape will work best when taping the plastic to the cinder block walls in the crawl space?

Thank you so much, from your reply I can see I need to keep looking for some source of moisture around this area.
