Dave Graham was to install an above ground pool in the ground along w/a deck & patio. The pool once it was installed, after almost 4 weeks at 2 to 5 hrs. here and there if and when he showed up, was unlevel by over 2 1/2 inches. The deck around the pool was below the coping on one side of the pool and about 5 inches above the coping on the other side of the pool. We had to pull up the composite decking in order to re construct the deck entirely. Upon doing this we discovered why the pool water was unlevel. One of the rails which he installed was bent at the bottom. The pool now has got to be drained out and totally removed in order to properly level and pack the ground under where the pool will rest and the bent rail will need to be replaced. We are not sure if the pool frame will need to be replaced as well for we'll need to hire a real "pool expert" to come and inspect this pool. David Graham did not even as much as have a transit. He was consatntly using our tools as well. He did not even as much as install a retaining wall for we had to do this. He and his so called "crew" of one and sometimes two, had a total disrespect for ones property. All trash was thrown on the ground & under the deck. We had to tell him that was unexceptable and we did not want over 30 empty sand bags, concrete bags, dunkin donuts cups, gatorad bottles and food bags all over the grounds and buried under our "new warped deck". We also found the directions for the pool filter buried under the deck. Davis Graham also wants all the money for the job before the work is even done or completed. Claims he is licensed and insured...yet to be seen.
