Contracter #1 came up with a solution of putting a sump pump in the area where the water occurs. Seems easy, cheap, costing around $1000. He said that there is no guarantee water will not leak in in the future and that water that may be in the cinder block walls may leak so he suggested a floor drain system for an additional $4000.
Contractor #2 came up with a much more elaborate solution as well as identifying the problem to be much more severe. His assessment was that there is definately water in the cinder block walls as well as underneath the floor and that the water contains acids from the clay, dirt, etc which damage the mortar of the wall and will lead to structural damage. So... his solution consists of a sump pump system, perforated plastic piping underneath the floor, bleeding the water out of the cinder blocks, blasting mold killing chemicals into the cinder block cavities. All this for $12,000.
Is contractor 2's solution overkill? Seems like a lot more work at a much higher cost. Is it worth it? I do plan to be in the house for many years to come.
Is the acid a major problem in basement water problems? Also, how big a deal is mold inside the cinder blocks? I recently got a dehumidifier and I don't smell any musty odor anymore.
Any comments and suggestions appreciated.Thanks
