Out of all the floors we’ve installed…we’ve never weaved into existing hardwoods before… until now!! What a process!! Holy cow!! Travis and Justin from 2 brothers flooring… were AMAZING!!!! Seriously, we’ve worked with a lot of sub contractors before… but this guy takes the cake. On time, courteous, trustworthy, HARD WORKING, and didn’t stop until the job was done AND PERFECT!! HE WAS AWESOME!!! The process took several days and we had to be very strategic with our timing of everything. Our 7 day renovation timeline was definitely ran by the timing and install of the floors. First they had to take out the existing 12 ft transition piece and weave the new floor in. Then they covered the entire floor with a wood filler to fill in all the cracks, then they sanded that off. Next they sanded the entire floor throughout the first floor… three times!! Then they stained it and put two coats of polyurethane on it… phew!!
