We had a tricky bit of hardwood floor to repair in a small hallway and were initially very happy that Sean agreed to do the work so quickly. After the project was completed, however, we were quite unhappy with a number of aspects of the work.
The biggest problem was that the work was quite sloppy. Sean left a large gap between two boards, screwed through the top of another board, and left a few very short and unstable pieces right at the edge of the floor.
Secondly, we had initially discussed attempting to level or at least flatten the subfloor before laying the boards. Sean unfortunately did not address this issue and instead merely used a great deal of glue to level the floor.
Finally, we were also very unhappy that he left quite a lot of garbage around, as well as pencil marks on some of the boards, and no trim replaced. I actually had to dig the hardware for our closet door out of a trash bag he left.
Overall, I would say that the work was done quickly and cheaply, but that you get what you pay for. We did not even bother addressing how unhappy we were with Sean because we didn't want him to do more work in our house.
Edit June 29th, 2013: These photos were taken after Sean finished the job and had been paid. We're even more unhappy at the lack of professionalism following this review.
