We hired Jay/Nader for tile and grout cleaning in kitchen and bathrooms.
He promised to remove the grease and bring back tiles and grout to original condition including grout color. He did an OK job in kitchen but a sloppy job in bathrooms.
We paid him while the tiles and grout were wet, so no way to check his work, but trusted him and his words as everything will be perfect when dry. it dried out and left lots of marks behind with areas he missed out. We called him to get him back, he promised to come and check his work but he never did.
Think again before hiring him and do not pay him until you check his work thoroughly.
