I contacted Jeff late 2011 to get an estimate for the above work. He provided estimate, but recommended he return early spring to do the work. (the pond was so dirty, and it would need another cleaning again in early summer if he did the work in late 2011). Jeff returned in March, and over the course of 2 weeks, he completed the work. (Note: I told Jeff that it would be hard for both of us to schedule 3-4 consecutive days to complete all the work, so we arranged for Jeff to come as our schedules permitted.) I am very happy with Jeff and Paradise Pond. I would absolutely use him again, and recommend him to anyone needing a new pond, a pond cleaning, a pond design update, or any pond related parts and services. Note: I met in 2010 when my pond filter died. I looked up vendors for pond pumps, called Jeff late in the afternoon on a Friday, and he delivered me the new pump within hours.
