Hi, I live in an 80 year old house for a year now. I have a half finished basement, with 4 areas that gets somewhat wet after big rain or winter melt. Those area are right under old downspouts no longer in use, but still may be collecting water somehow. They are disconnected from the real downspouts installed in more recent years.
The block wall part of the basement is not so bad except a bit discoloration. But one area has drywall on and is degrading and moldy.
I had three contractors came and got three different suggestions.
1. install internal drain system/sump
2. dig outside and seal the cracks with rubber material
3. change the gutter to bigger one (the worst two areas are right under steep roof, that he said is likely feeding water underneath) and add more dirt for grading.
Cost: 3My floor is a tile floor and am not so excited about internal drain system, but sound more reliable than option 3. Digging I found has two opposite opinions on web.
Any suggestions where to start? Which option is the best for the house?
Thanks in advance!
