Francisco and his crew, including his son, did a fantastic job. We have some hundred-year-old pine floors, several of which were painted with very old oxblood paint. They never looked good, but Francisco sanded, stained and coated them, and now they look fantastic. He used a neutral oil-based stain and several coats of polyurethane coating, which he had to apply by hand because there were largish gaps between the floorboards. He's clearly a perfectionist, and there were no little bits of paint missed along the edges and so on.
The job included a landing and a flight of stairs. I was surprised that he was able to easily handle the rounded lips of the stairs, and absolutely amazed that he was able to get in between the bannister support legs, which are not even two inches apart. I wish I had been able to see how he did that, but the area was sealed off with plastic sheeting to contain the dust.
He and his crew showed up when they said they would, and worked efficiently until the job was done. It took about four days (the sanding took two days). His price was quite reasonable, probably because as an owner-operator, he did some of the work himself and we weren't paying extra to deal with a separate sales staff.
I would recommend him to anybody. We plan on having him back to do a couple more floors that couldn't be done at the time.
