Comment: Technicians were friendly and professional. I know most companies outsource to sub contractors and the last two companies that came out to clean our wood floors were sent away due to not knowing what they were talking about or understanding what needed to be done. These guys were great, the only thing I wish they had done, was being a little more careful applying the grout sealer, it is on the tiles as well and has been very hard to clean up. The spots make the floor look dirty..
