I hired Martin to remove old carpeting from two bedrooms, install unfinished hardwood (strip flooring) because the adjacent hallway had old strip flooring and I wanted to match the floors. The scope of his job included finishing (sanding, filling, staining and finishing) the newly installed hardwood in the two bedrooms plus the existing hardwood in the hallway in order to make them match.
The end result is beautiful. You can't tell which is the old and the newly installed hardwood. They're seamless.
We're really happy with the job.
The only negative was that I had the walls and trim of the bedrooms painted white a week before Martin started his job. I should have had the painting done after the floors because when Martin was done there were scuffs and dusty hand prints on the walls which I was able to wash off with Mr. Clean magic eraser and a damp cloth for most areas but also had to resort to using spackling and paint for other areas where small bits of drywall were scraped from the wall and in one spot from the ceiling which I assume was damaged when they removed/replaced the doors. Also, the job was dusty despite them using dust-reducing sanders which vacuums the dust as it sands. I think the dust was unavoidable though due to the nature of the job involving sanding of entire floor surface. Next time I would do a better job of blocking off parts of the house with sheets of plastic.
