Didn't take very long to complete, made me want to learn to do it myself since it looked so easy and was fast to do. Jeff was great though, he was very professional and he laid out our beautiful sydney blue hardwood floors perpendicular to the floor joists. There were no cracks or spaces between them, it was neatly done. The dust was vacuumed off the sanded floor, and most of the fine dust was picked up with rags. We are completely satisifed with the job and love walking on our wooden floors.
