The downspout exit is critical. If they're dumping water next to the foundation, you'll always have problems.
I had to hire a backhoe to come in and dig down to the bottom of my foundation to take care of a severe water problem on a house I bought 20 years ago. They knocked a hole in the block and hundreds of gallons of water came out of the block wall. Water flowed out for hours. They added French drains and I rerouted the downspout flow. Never had another problem.
