    We had an emergency on Saturday and they not only picked up the phone but asked us to take pictures of what we were seeing. Thank fulling it was our sensor on our septic that had failed and not an emergency. They kept in contacted and told us to save our money on a Saturday emergency call and would come on Tuesday. First tech came on time and their plumber came at 6pm to replace the part. We live in Washougal in the country and we are super impressed with their friendleness and professionalism. We will be using them for all future septic maintenance.
