“

Needed the floor in our downstairs bathroom glued down and Carl found a water damage and mold issue. He did an excellent job replacing the floor and suggested waterproof vinyl laminate in place of one-piece vinyl for the flooring. I purchased the flooring at Alfieri's and love Carl's suggestion. Would highly recommend Carl's workmanship! He has done deck stairs work in the past for us and I have no hesitation in calling on him. Very reasonable prices and excellent quality of the work done
