During the crazy rains after the August long weekend my girlfriend called me to tell me the water was coming in the basement door like a river. When I got back and the rains had subsided I tried to run a small hand snake down the outdoor drain but quickly hit the obstacle. Armelin from New Canadians came with the snake and told me my options. I didn't think I needed the video, I knew it was blocked and was pretty sure it was the giant chestnut tree beside the house getting its roots into the drain. He went to work with the snake and quickly got in to the tangle of roots. It certainly didn't look easy but he kept at it, pulling the snake out 3 times to clear it of roots up to 3/8" in diameter. Finally the snake was coming out clear and water was running easily. Today, a month later, it is pouring rain and there is no pooling at all at the drain, clean as a whistle. The roots will eventually be back. I will call New Canadians again.
