Description of Work: Grennan Construction cleaned our gutters and did an excellent job. The first morning we were scheduled for service they showed up before the scheduled time. We had one little hiccup though, because we had not informed the crew that our home was so tall (our fault) they didn't have a ladder tall enough to finish the project. They said they would be back first thing the next morning to finish. It rained hard all the next day-I would never have expected them to work in the rain, but I was disappointed when they didn't call to re-schedule. They didn't call for several days, but when they did call back, they very sincerely apologized and we set up another time for them to come out. They showed up early (again) for the next scheduled appt. and they were very courteous - careful around plantings - and cleaned up our yard nicely. I would most definitely hire them again. Even after our "hiccup".
