Hi, I have an 80-year-old house I purchased last year. The basement is half finished and the finished part has a fireplace, tile floor (looks new, probably 2-3 years old) and surrounded with drywall.
There are three area in the basement that gets a little wet when it rains or when the snow melts. One area happens to be finished drywall, and the wall has big watermarks and is breaking down. The unfinished part has blocked wall painted white, and you see the discoloration.
These three area is right under the old drain system that used to be hooked to the gutter downspout, that are not in use currently.
There are several expensive option if I want to fix the problem permanently. Which I am not so sure because I might be moving in the next 5 years. Is there any obvious I can do before the considering more expensive option (digging exterior to seal the cracks, installing drain system in the basement etc).
Am thinking of -
(1) Extend the gutter downspout (although it is pretty extended now).
(2) Clay soil around the house to grade
(3) Water proof coating on the interior wall
(4) "French drain"
I also saw that grass would prevent water to soak in. Currently the house is surrounded with flower bed - is planting grass help relieve the problem?
Appreciate any advise - thanks!
