After we bought our 100-year-old house, I did a lot of research before attempting to fix our horrible basement flooding. After every medium to heavy rainfall, our entire basement would be covered with 3 to 6 inches of water. I spent days pumping water after every rain shower. French Drain Man was easily the best resource I could find, from their excellent help videos to their superb products. We called several businesses to help us and they all wanted $3,500 or more for minor fixes. Most said we had to pay well over $10,000 to add additional sump pumps and French drains along the all basement walls. After less than $1,000 and three days of work (following the advice of French Drain Man and using my favorite FDM products), I stopped our basement flooding. It's now bone dry and has been that way for almost one year. I especially love their popup emitters and downspout leaf filters. Definitely worth the extra cost, and shipping was fast. I could not be happier with FDM!
