I had these guys refinish the hardwood floors in my house. The stain looked fine(minus a few missed spots which they corrected after I pointed it out). The issue was in the prep work. The two men sanded grooves and ruts throughout the floor, along the edges of the trim(which they should have removed), and in spots where the wood meets tile. Another contractor later confirmed that this is unacceptable. A proper sander knows not to add pressure unevenly. Two-thousand dollars later, I cringe each time the light catches the mistakes in my once gorgeous floors. I should have left it alone.
