How to Seal a Water Leak
• Look for areas of condensation in your home and basement.
Condensation is what occurs when moist, warm air comes in contact
with cool walls. If you notice any wet areas on the floors or walls,
this could signal a problem with condensation. There is an easy test
you can perform to see if you are experiencing an issue with
condensation. Tape some plastic wrap to the wall, ensuring that it is
completely sealed to the wall. Leave it there for a few days. When
you return to the area, check to see if there is any moisture build-up
within the plastic wrap. If you see moisture on the wall covered by
the plastic wrap, you have a leak. If there is moisture on the outside
of the plastic wrap, then it is condensation.
• If it turns out to be a condensation problem, that can be easily
resolved: open a few windows to let the air circulate and also install
a dehumidifier in the room.
• If it is a leak, you are going to have to take more serious steps to fix
the problem. A sealant must be applied to the area to mend the
leak. There are many types of sealants made for repairing water
leaks. You must do your homework and figure out which one is right
for your situation. Sealants can be placed on a damp surface;
however, if there is any standing water, it must be removed first.
