I would recommend A-1 to anyone and have. We recently had our two story, 12,000 square foot, office building cleaned and I was pleased with the results. From the time I called in for the appointment, it was only a week later that we had the work done after first receiving a quote. Juan, the A-1 tech was efficient and clean while working. There was no damage to the walls or other flooring from his hoses. Again, I would recommend A-1 to anyone.
