We had hardwoods put into our family room and the existing hardwoods refinished. Kimminau was able to lace the new floors into the existing floors in two rooms and the transition is seamless! The entire process only took 4 days and we did not have to leave the house. Was amazed at how CLEAN the house was at the end of each day. Dust was very minimal. A much cleaner process than we experienced the last time our floors were refinished by a different company. Very satisfied with the results!!
