We are getting our floors sanded. MY daughter got a new house but they did not have the money to sand the floors so I bought the materials for her house and mine and her husband is doing the work on both. The estimate for mine from the commercial company was $1600 but the materials for both (sander, sanding disks, stain and sealer) is $450. A good deal I think!
BTW, Rafael (the step grand son from Cuba) is 14 and a freshman in high school! He is pulling staples from the crap carpet job the previous owner did to hold the carpet in place.
