What a wonderful pond/waterfall I have. Willie and Tito not only were professional but so polite. Willie explained what they would do at the beginning and also during construction. After construction, Willie not only cleaned up but explained to me the maintenance for the pond. I had used a company in my area to make a waterfall and they never completed the project and all i had was a non functioning pong with a lot of rock. This company is the best. So so happy!
