Our crawlspace filled up with water the day before New Year's Eve. Drain Inspectors was on the scene right away and quickly determined that our sewer line had roots in it. They used a camera to take and show pictures of the stoppage. They made a temporary fix that eliminated the water right away, then returned three weeks later to take care of the problem for the longterm. They advised me on the condition of the line and roots penetrating the line and recommended regular service every couple of years. Fast and friendly and they could show their work thanks to the camera. Icing on the cake: Two hours after they left, my kitchen sink stopped draining. I called them to come back and, instead, the talked me through a solution over the phone. No charge. Good guys.
