Ruben We are very much grateful for the wonderful job you have done on our pond. The two water falls are working perfectly well, and the rock work is just excellent. We had this pond a while and were just about to give up as it was not done right before. You corrected everything so well, and now we are the proud owner of a very nice pond that added so much to the beauty of the house. Thanks you very much for the excellent work you did. I am sure that we are one of your many very satisfied customers.
