I had my carpet installed 30 years ago and I have been using Lewis Carpet Cleaners every year for around 20-25 years. I think the cleaning that they do has helped my carpets last year after year. They also have educated me on how to maintain my carpet between cleanings. My carpet is a pale yellow so it gets dirty easily. After each cleaning, the carpet looks so amazing and it's like we moved into a brand new home. If for some reason I am not happy, Lewis will come back to my home and remove the stain. In the past, I have tried cleaning the carpet myself or tried another company but the results aren't the same as Lewis. I highly recommend Lewis Carpet Cleaners and will continue to use them for many years to come.
