Why does my ceiling crack?

A. A ceiling that keeps cracking may be due to the plaster being too thick or it cured too fast , or both. But if repeated repairs did not work I suggest you go back to a time-honored technique. I did not invent it, but I have suggested it to many people, with no replies that it did not work.

Can a window be caulked on the outside?

A. Yes , it is faulty window installation. If the windows were caulked on the outside, moisture may have been trapped behind the frames, and decay occurred. I don’t think windows should be caulked on the outside for this very reason. Normally when a new window is installed, strips of tarpaper are applied to the sheathing on each side and the top, then the frame (casing) is installed, and finally the siding. This may be old-fashioned, but it allows water to run behind the frame and downward, dissipating harmlessly. It is called drainage. Another important thing is window flashing, an L-shaped piece of metal or plastic at the top of the window frame. One leg of the L goes under the siding, the other leg folds over the top of the frame. If there is no window flashing, decay will quickly follow. A third reason for failure is the outside sill. It is unlikely, but if the sill is level and not slanting downward, decay is sure to follow. Those windows need an expert who knows what the heck he is doing.
