My carpet was just filthy - lots of high-traffic dirty areas. Low-and-behold, Sam got it clean! I only have 2 carpeted rooms, so I couldn't take advantage of his Five Rooms for $80 special, so he only charged me $40 for both rooms! No ridiculous minimum charges! And, since the previous owners who installed the carpet went cheap, Sam gave me pointers on what to look for in the future when I install my own new carpet, everything from the best type of carpet fiber, to padding, to fiber guard. Thank you, Sam!
