Another way to do the leak repair is:
- Have some clear vapor barrier plastic ready (hardware store carries them, used for laying down on the basement floor before concrete is poured, it is also called a vapor barrier at hardware store!).
- Go to any autoglass place and buy a roll of "butyl". It has a diameter of your pinky finger. The autoglass shop uses this to install windshield glass for older cars.
I just bought a roll of 15 feet for $15 (roughly $1/foot), but I used it for my leaky home skylight on my roof (this is another story!!!).
- Re toddler, place the toddler to bed at lunch time during weekend and you have time to do it. About 1h labor.
