I would recommend Patrick and the Carpet Repair Guys. I had some major ripples in my upstairs carpet which was not a repair that i would ever think that i needed to be done, but since i couldn't close my doors without rubbing on the carpet, you have to get it done. The work was completed for a reasonable price and comes with a guarantee. I had to vacuum up afterwards which i really didn't mind as his prices were lower than the competition, and it enabled me to get a real close look at the work (which appears to be done quite well). Apparently rippling is quite common in new home construction and I was really surprised how much the carpet had to be stretched to remove the waves.
