We needed the upper main floor of our 60's home refinished and stair treads replaced. Our floors are red oak and original, so we wanted to preserve the flooring.
I interviewed several companies before settling with AHF. One thing to consider is that for all other companies, I wasn't sure who would be doing the actual work. With AHF you actually get to meet Ken who does the refinishing, so you know that you are going to get someone that is actually skilled in the job.
Ken was very considerate, responsive to our calls, and left the place tidy and clean each day. Everything sealed so there were no issues of dust. He definitely knows his trade and has been in the flooring business for his entire career. The quality of our floors look great, right up to the edges. The only thing I was a bit surprised at was the nails are very visible now that we have a clear coat, but hopefully the will disappear over time like the last finish that was on there. The best part is our stair treads, which look amazing. We chose to go with the Glitza product because it is known to last. So in summary, Ken did a great job, was trustworthy, and knows hardwood floors inside and out.
