They do a good job overall when they focus but this focus seldom happens. Crews on my projects did not appear to have a person in charge or if someone was in charge that person could not lead. There is a dearth of Quality Control (QC) and Quality Assurance(QA) that led to incomplete projects and erroneous results. I often had to get personnel to return to fix problems that should never had been necessary if they had a good QC and QA approach. These are the firm's problem areas on my projects: 1. Firm-installed water feature leaked an enormous amount of water. The firm checked the feature and declared there was no leak. However it still leaked a lot of water and personnel had to return 2 more times to finally solve the problem. I got the bill for the water. 2. Prior to fixing the water feature leak, I shut off the water to the feature. When the crew returned to continue work, for some reason they turned the water on to the feature even though they knew there was a leak. 3. Shut-off float on a water feature failed repeatedly. 4. Precipitation gauges did not work. The firm took 5 trips to address this. I'm still not sure they work. 5. Shut-off valve to a water feature was not initially installed even though the design called for one to be installed. 6. After 2 years, the bluegrass died and I had to replace it at my cost. 7. A sprinkler control in one sprinkler-area was sodded over and I have no idea where it is. 8. When grass was re-sodded, areas around bushes and trees were left bare and muddy. To date, there are still bare areas and there are dry areas that are not getting water from the sprinkler system. For the past several weeks, I have repeatedly contacted the firm via phone and email about this and they haven't addressed this to date (16 Oct 2011). 9. A bush was dug up to be placed elsewhere but was simply left on the ground. 10. There was ivy running up a tree and I repeatedly asked the firm not to cut it. Guess what happened? 11. Several weeks ago a crew cut my front lawn and I did not request this service. 12. Several weeks ago, I've received an invoice with no explanation as to what it is for. Called firm and left a voice message. As usual, I have yet to hear from them.
