We hired Mud Monkeys for waterproofing one wall from which water was seeping into the basement. They offered us three different ways to fix it (and recommended we do the cheapest one!). We had a French drain put in as well as waterproofing of the wall. It was a very fast process, it only took about two days. There was a sump pump (plumbing) charge above what Mud Monkeys charged but we were reimbursed through the City. We've now been through a very rainy year with no water in the basement at all. Note: Mud Monkeys does the demo/prep work but you'll need to hire someone to put the wall/floor back together after. We did the demo work ourselves and they were cool with that. If there are specific ways you want the demo/prep work done, you should let them know in advance/while they are working. I would definitely recommend them to others as the cost was much less than what we were anticipating and the process was very fast.
