Re: Storm window question
The two weep holes on the bottom of the storm window unit are plugged either with debris or paint.
HOME CLINIC; Smoothing the Way For Storm Windows
Poke a wire through the weep holes at the base of the frame to clear the holes of debris. Weep holes allow moisture from condensation to escape from the space between the primary windows and the storm windows when the storm windows are closed. Moisture trapped between the windows can cause wood window sills to decay.
If you cannot find weep holes, they may be covered with caulking compound. Replace old caulking that is dry and cracked, instead of poking through it with the wire. To do that, gouge out the caulking from the seam with a screwdriver or other pointed tool. Next, clean the area by brushing it free of debris and wiping it with a cloth dipped in mineral spirits. Apply fresh caulking with a caulking gun and poke open the weep holes immediately.
In the winter, if condensation forms on the inside of storm windows, add or replace weatherstripping around the primary sashes. That will keep warm indoor air from entering into the space between the windows, which causes the problem.
If condensation forms on the inside of the primary windows, the problem is usually that the storm windows are allowing cold air from outside to enter the space. Weep holes can cause condensation, but noticeable problems are usually the result of looseness.
