Take me once, shame on you. Take me twice, shame on me.
Several years ago we had our existing floors re-finished by this firm, and they used a highly carcinogenic finish and failed to tell us about how dangerous the product was (we found out in our own research).
A few months ago, this firm was used again through our General Contractor on a larger project of ours. We knew he was hiring them, but figured they couldn't screw up twice; boy were we wrong. They installed new floors this time, in a new area of the house. The installation went fine, but the finishing was a nightmare that set the larger project back a couple of weeks. Our GC noticed some problems with some filler used on the floor, and had a supervisor come take a look. Sure enough, the wrong filler had been used, so the floors had to be re-sanded and finished again. The supervisor fired one of the employees who had done the initial finish as he'd been a problem for awhile (lucky me had this guy working on my project), and the other one quit. The next round of finishing left severe discoloration all over the place do to pooling (unskilled application; again!). They came out to sand, for the third time, and re-applied. Finally the finish was right, but they'd failed to take the heater vents off and finish them independently, so they were sealed into the floor and required someone else to carve them free.
I have a feeling Floor Crafters has a corner on the Boulder market, so, as with any good monopoly, then can provide a poor product. I particularly enjoyed the fact that Floor Crafters made no offer to discount their work, which ultimately cost us a couple of extra thousand dollars in setbacks and delays.
