How do I fix a wet crawl space?

Question

And how much will it cost me

Answer 1

If rain water is getting in, not much you can do except relandscaping or trenching around the exterior and installing a drainage system.
Otherwise if it is just dampness you would have to add additional ventilation. You can also install plastic sheeting over the ground which will block most of the moisture getting into the house. There are too many variables to estimate a price.
Sometimes adding roof gutters and directing the rain water away from the exterior walls is sufficient.

Answer 2

How wet? I mean, are we talking standing water wet? or just damp.
I think most all crawl spaces are damp, I put a bucket of charcoal in mine to keep the mold down.
If you have actual water there, You have a more serious problem.
You have a leak somewhere.

Answer 3

First find out the problem. Damaged drain tiles? Broken drain pipe from the perimeter? Increasing water table in your area?
These are foundation problems, and it is best to get some pros for estimates. Hire the one who does the most extensive examination, does not look only at this problem but will address future ones based on what is happening now.

Answer 4

Interior vs exterior fix? Interior fix is cheaper...entire basement perimeter likely between $5-7000. For a proper job good luck

Answer 5

We have a sump pump in our crawl space....hubby put it in himself, wired it himself, so I can't tell you how much it would cost. I'm thinking not too much. Sorry I can't be of more help
